The purpose of `$animateCss` is NOT - * to side-step how `$animate` and ngAnimate work, but the goal is to allow pre-existing animations or - * directives to create more complex animations that can be purely driven using CSS code. - * - * Note that only browsers that support CSS transitions and/or keyframe animations are capable of - * rendering animations triggered via `$animateCss` (bad news for IE9 and lower). - * - * ## General Use - * Once again, `$animateCss` is designed to be used inside of a registered JavaScript animation that - * is powered by ngAnimate. It is possible to use `$animateCss` directly inside of a directive, however, - * any automatic control over cancelling animations and/or preventing animations from being run on - * child elements will not be handled by AngularJS. For this to work as expected, please use `$animate` to - * trigger the animation and then setup a JavaScript animation that injects `$animateCss` to trigger - * the CSS animation. - * - * The example below shows how we can create a folding animation on an element using `ng-if`: - * - * ```html - * - *
- * This element will go BOOM - *
- * - * ``` - * - * Now we create the **JavaScript animation** that will trigger the CSS transition: - * - * ```js - * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) { - * return { - * enter: function(element, doneFn) { - * var height = element[0].offsetHeight; - * return $animateCss(element, { - * from: { height:'0px' }, - * to: { height:height + 'px' }, - * duration: 1 // one second - * }); - * } - * } - * }]); - * ``` - * - * ## More Advanced Uses - * - * `$animateCss` is the underlying code that ngAnimate uses to power **CSS-based animations** behind the scenes. Therefore CSS hooks - * like `.ng-EVENT`, `.ng-EVENT-active`, `.ng-EVENT-stagger` are all features that can be triggered using `$animateCss` via JavaScript code. - * - * This also means that just about any combination of adding classes, removing classes, setting styles, dynamically setting a keyframe animation, - * applying a hardcoded duration or delay value, changing the animation easing or applying a stagger animation are all options that work with - * `$animateCss`. The service itself is smart enough to figure out the combination of options and examine the element styling properties in order - * to provide a working animation that will run in CSS. - * - * The example below showcases a more advanced version of the `.fold-animation` from the example above: - * - * ```js - * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) { - * return { - * enter: function(element, doneFn) { - * var height = element[0].offsetHeight; - * return $animateCss(element, { - * addClass: 'red large-text pulse-twice', - * easing: 'ease-out', - * from: { height:'0px' }, - * to: { height:height + 'px' }, - * duration: 1 // one second - * }); - * } - * } - * }]); - * ``` - * - * Since we're adding/removing CSS classes then the CSS transition will also pick those up: - * - * ```css - * /* since a hardcoded duration value of 1 was provided in the JavaScript animation code, - * the CSS classes below will be transitioned despite them being defined as regular CSS classes */ - * .red { background:red; } - * .large-text { font-size:20px; } - * - * /* we can also use a keyframe animation and $animateCss will make it work alongside the transition */ - * .pulse-twice { - * animation: 0.5s pulse linear 2; - * -webkit-animation: 0.5s pulse linear 2; - * } - * - * @keyframes pulse { - * from { transform: scale(0.5); } - * to { transform: scale(1.5); } - * } - * - * @-webkit-keyframes pulse { - * from { -webkit-transform: scale(0.5); } - * to { -webkit-transform: scale(1.5); } - * } - * ``` - * - * Given this complex combination of CSS classes, styles and options, `$animateCss` will figure everything out and make the animation happen. - * - * ## How the Options are handled - * - * `$animateCss` is very versatile and intelligent when it comes to figuring out what configurations to apply to the element to ensure the animation - * works with the options provided. Say for example we were adding a class that contained a keyframe value and we wanted to also animate some inline - * styles using the `from` and `to` properties. - * - * ```js - * var animator = $animateCss(element, { - * from: { background:'red' }, - * to: { background:'blue' } - * }); - * animator.start(); - * ``` - * - * ```css - * .rotating-animation { - * animation:0.5s rotate linear; - * -webkit-animation:0.5s rotate linear; - * } - * - * @keyframes rotate { - * from { transform: rotate(0deg); } - * to { transform: rotate(360deg); } - * } - * - * @-webkit-keyframes rotate { - * from { -webkit-transform: rotate(0deg); } - * to { -webkit-transform: rotate(360deg); } - * } - * ``` - * - * The missing pieces here are that we do not have a transition set (within the CSS code nor within the `$animateCss` options) and the duration of the animation is - * going to be detected from what the keyframe styles on the CSS class are. In this event, `$animateCss` will automatically create an inline transition - * style matching the duration detected from the keyframe style (which is present in the CSS class that is being added) and then prepare both the transition - * and keyframe animations to run in parallel on the element. Then when the animation is underway the provided `from` and `to` CSS styles will be applied - * and spread across the transition and keyframe animation. - * - * ## What is returned - * - * `$animateCss` works in two stages: a preparation phase and an animation phase. Therefore when `$animateCss` is first called it will NOT actually - * start the animation. All that is going on here is that the element is being prepared for the animation (which means that the generated CSS classes are - * added and removed on the element). Once `$animateCss` is called it will return an object with the following properties: - * - * ```js - * var animator = $animateCss(element, { ... }); - * ``` - * - * Now what do the contents of our `animator` variable look like: - * - * ```js - * { - * // starts the animation - * start: Function, - * - * // ends (aborts) the animation - * end: Function - * } - * ``` - * - * To actually start the animation we need to run `animation.start()` which will then return a promise that we can hook into to detect when the animation ends. - * If we choose not to run the animation then we MUST run `animation.end()` to perform a cleanup on the element (since some CSS classes and styles may have been - * applied to the element during the preparation phase). Note that all other properties such as duration, delay, transitions and keyframes are just properties - * and that changing them will not reconfigure the parameters of the animation. - * - * ### runner.done() vs runner.then() - * It is documented that `animation.start()` will return a promise object and this is true, however, there is also an additional method available on the - * runner called `.done(callbackFn)`. The done method works the same as `.finally(callbackFn)`, however, it does **not trigger a digest to occur**. - * Therefore, for performance reasons, it's always best to use `runner.done(callback)` instead of `runner.then()`, `runner.catch()` or `runner.finally()` - * unless you really need a digest to kick off afterwards. - * - * Keep in mind that, to make this easier, ngAnimate has tweaked the JS animations API to recognize when a runner instance is returned from $animateCss - * (so there is no need to call `runner.done(doneFn)` inside of your JavaScript animation code). - * Check the {@link ngAnimate.$animateCss#usage animation code above} to see how this works. - * - * @param {DOMElement} element the element that will be animated - * @param {object} options the animation-related options that will be applied during the animation - * - * * `event` - The DOM event (e.g. enter, leave, move). When used, a generated CSS class of `ng-EVENT` and `ng-EVENT-active` will be applied - * to the element during the animation. Multiple events can be provided when spaces are used as a separator. (Note that this will not perform any DOM operation.) - * * `structural` - Indicates that the `ng-` prefix will be added to the event class. Setting to `false` or omitting will turn `ng-EVENT` and - * `ng-EVENT-active` in `EVENT` and `EVENT-active`. Unused if `event` is omitted. - * * `easing` - The CSS easing value that will be applied to the transition or keyframe animation (or both). - * * `transitionStyle` - The raw CSS transition style that will be used (e.g. `1s linear all`). - * * `keyframeStyle` - The raw CSS keyframe animation style that will be used (e.g. `1s my_animation linear`). - * * `from` - The starting CSS styles (a key/value object) that will be applied at the start of the animation. - * * `to` - The ending CSS styles (a key/value object) that will be applied across the animation via a CSS transition. - * * `addClass` - A space separated list of CSS classes that will be added to the element and spread across the animation. - * * `removeClass` - A space separated list of CSS classes that will be removed from the element and spread across the animation. - * * `duration` - A number value representing the total duration of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `0` - * is provided then the animation will be skipped entirely. - * * `delay` - A number value representing the total delay of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `true` is - * used then whatever delay value is detected from the CSS classes will be mirrored on the elements styles (e.g. by setting delay true then the style value - * of the element will be `transition-delay: DETECTED_VALUE`). Using `true` is useful when you want the CSS classes and inline styles to all share the same - * CSS delay value. - * * `stagger` - A numeric time value representing the delay between successively animated elements - * ({@link ngAnimate#css-staggering-animations Click here to learn how CSS-based staggering works in ngAnimate.}) - * * `staggerIndex` - The numeric index representing the stagger item (e.g. a value of 5 is equal to the sixth item in the stagger; therefore when a - * `stagger` option value of `0.1` is used then there will be a stagger delay of `600ms`) - * * `applyClassesEarly` - Whether or not the classes being added or removed will be used when detecting the animation. This is set by `$animate` when enter/leave/move animations are fired to ensure that the CSS classes are resolved in time. (Note that this will prevent any transitions from occurring on the classes being added and removed.) - * * `cleanupStyles` - Whether or not the provided `from` and `to` styles will be removed once - * the animation is closed. This is useful for when the styles are used purely for the sake of - * the animation and do not have a lasting visual effect on the element (e.g. a collapse and open animation). - * By default this value is set to `false`. - * - * @return {object} an object with start and end methods and details about the animation. - * - * * `start` - The method to start the animation. This will return a `Promise` when called. - * * `end` - This method will cancel the animation and remove all applied CSS classes and styles. - */ -var ONE_SECOND = 1000; + oldAnimation.addClass = target.addClass; + oldAnimation.removeClass = target.removeClass; -var ELAPSED_TIME_MAX_DECIMAL_PLACES = 3; -var CLOSING_TIME_BUFFER = 1.5; + return target; + } -var DETECT_CSS_PROPERTIES = { - transitionDuration: TRANSITION_DURATION_PROP, - transitionDelay: TRANSITION_DELAY_PROP, - transitionProperty: TRANSITION_PROP + PROPERTY_KEY, - animationDuration: ANIMATION_DURATION_PROP, - animationDelay: ANIMATION_DELAY_PROP, - animationIterationCount: ANIMATION_PROP + ANIMATION_ITERATION_COUNT_KEY -}; + function resolveElementClasses(existing, toAdd, toRemove) { + var ADD_CLASS = 1; + var REMOVE_CLASS = -1; -var DETECT_STAGGER_CSS_PROPERTIES = { - transitionDuration: TRANSITION_DURATION_PROP, - transitionDelay: TRANSITION_DELAY_PROP, - animationDuration: ANIMATION_DURATION_PROP, - animationDelay: ANIMATION_DELAY_PROP -}; + var flags = {}; + existing = splitClassesToLookup(existing); -function getCssKeyframeDurationStyle(duration) { - return [ANIMATION_DURATION_PROP, duration + 's']; -} + toAdd = splitClassesToLookup(toAdd); + forEach(toAdd, function (value, key) { + flags[key] = ADD_CLASS; + }); -function getCssDelayStyle(delay, isKeyframeAnimation) { - var prop = isKeyframeAnimation ?

Therefore CSS hooks + * like `.ng-EVENT`, `.ng-EVENT-active`, `.ng-EVENT-stagger` are all features that can be triggered using `$animateCss` via JavaScript code. + * + * This also means that just about any combination of adding classes, removing classes, setting styles, dynamically setting a keyframe animation, + * applying a hardcoded duration or delay value, changing the animation easing or applying a stagger animation are all options that work with + * `$animateCss`. The service itself is smart enough to figure out the combination of options and examine the element styling properties in order + * to provide a working animation that will run in CSS. + * + * The example below showcases a more advanced version of the `.fold-animation` from the example above: + * + * ```js + * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) { + * return { + * enter: function(element, doneFn) { + * var height = element[0].offsetHeight; + * return $animateCss(element, { + * addClass: 'red large-text pulse-twice', + * easing: 'ease-out', + * from: { height:'0px' }, + * to: { height:height + 'px' }, + * duration: 1 // one second + * }); + * } + * } + * }]); + * ``` + * + * Since we're adding/removing CSS classes then the CSS transition will also pick those up: + * + * ```css + * /* since a hardcoded duration value of 1 was provided in the JavaScript animation code, + * the CSS classes below will be transitioned despite them being defined as regular CSS classes */ + * .red { background:red; } + * .large-text { font-size:20px; } + * + * /* we can also use a keyframe animation and $animateCss will make it work alongside the transition */ + * .pulse-twice { + * animation: 0.5s pulse linear 2; + * -webkit-animation: 0.5s pulse linear 2; + * } + * + * @keyframes pulse { + * from { transform: scale(0.5); } + * to { transform: scale(1.5); } + * } + * + * @-webkit-keyframes pulse { + * from { -webkit-transform: scale(0.5); } + * to { -webkit-transform: scale(1.5); } + * } + * ``` + * + * Given this complex combination of CSS classes, styles and options, `$animateCss` will figure everything out and make the animation happen. + * + * ## How the Options are handled + * + * `$animateCss` is very versatile and intelligent when it comes to figuring out what configurations to apply to the element to ensure the animation + * works with the options provided. Say for example we were adding a class that contained a keyframe value and we wanted to also animate some inline + * styles using the `from` and `to` properties. + * + * ```js + * var animator = $animateCss(element, { + * from: { background:'red' }, + * to: { background:'blue' } + * }); + * animator.start(); + * ``` + * + * ```css + * .rotating-animation { + * animation:0.5s rotate linear; + * -webkit-animation:0.5s rotate linear; + * } + * + * @keyframes rotate { + * from { transform: rotate(0deg); } + * to { transform: rotate(360deg); } + * } + * + * @-webkit-keyframes rotate { + * from { -webkit-transform: rotate(0deg); } + * to { -webkit-transform: rotate(360deg); } + * } + * ``` + * + * The missing pieces here are that we do not have a transition set (within the CSS code nor within the `$animateCss` options) and the duration of the animation is + * going to be detected from what the keyframe styles on the CSS class are. In this event, `$animateCss` will automatically create an inline transition + * style matching the duration detected from the keyframe style (which is present in the CSS class that is being added) and then prepare both the transition + * and keyframe animations to run in parallel on the element. Then when the animation is underway the provided `from` and `to` CSS styles will be applied + * and spread across the transition and keyframe animation. + * + * ## What is returned + * + * `$animateCss` works in two stages: a preparation phase and an animation phase. Therefore when `$animateCss` is first called it will NOT actually + * start the animation. All that is going on here is that the element is being prepared for the animation (which means that the generated CSS classes are + * added and removed on the element). Once `$animateCss` is called it will return an object with the following properties: + * + * ```js + * var animator = $animateCss(element, { ... }); + * ``` + * + * Now what do the contents of our `animator` variable look like: + * + * ```js + * { + * // starts the animation + * start: Function, + * + * // ends (aborts) the animation + * end: Function + * } + * ``` + * + * To actually start the animation we need to run `animation.start()` which will then return a promise that we can hook into to detect when the animation ends. + * If we choose not to run the animation then we MUST run `animation.end()` to perform a cleanup on the element (since some CSS classes and styles may have been + * applied to the element during the preparation phase). Note that all other properties such as duration, delay, transitions and keyframes are just properties + * and that changing them will not reconfigure the parameters of the animation. + * + * ### runner.done() vs runner.then() + * It is documented that `animation.start()` will return a promise object and this is true, however, there is also an additional method available on the + * runner called `.done(callbackFn)`. The done method works the same as `.finally(callbackFn)`, however, it does **not trigger a digest to occur**. + * Therefore, for performance reasons, it's always best to use `runner.done(callback)` instead of `runner.then()`, `runner.catch()` or `runner.finally()` + * unless you really need a digest to kick off afterwards. + * + * Keep in mind that, to make this easier, ngAnimate has tweaked the JS animations API to recognize when a runner instance is returned from $animateCss + * (so there is no need to call `runner.done(doneFn)` inside of your JavaScript animation code). + * Check the {@link ngAnimate.$animateCss#usage animation code above} to see how this works. + * + * @param {DOMElement} element the element that will be animated + * @param {object} options the animation-related options that will be applied during the animation + * + * * `event` - The DOM event (e.g. enter, leave, move). When used, a generated CSS class of `ng-EVENT` and `ng-EVENT-active` will be applied + * to the element during the animation. Multiple events can be provided when spaces are used as a separator. (Note that this will not perform any DOM operation.) + * * `structural` - Indicates that the `ng-` prefix will be added to the event class. Setting to `false` or omitting will turn `ng-EVENT` and + * `ng-EVENT-active` in `EVENT` and `EVENT-active`. Unused if `event` is omitted. + * * `easing` - The CSS easing value that will be applied to the transition or keyframe animation (or both). + * * `transitionStyle` - The raw CSS transition style that will be used (e.g. `1s linear all`). + * * `keyframeStyle` - The raw CSS keyframe animation style that will be used (e.g. `1s my_animation linear`). + * * `from` - The starting CSS styles (a key/value object) that will be applied at the start of the animation. + * * `to` - The ending CSS styles (a key/value object) that will be applied across the animation via a CSS transition. + * * `addClass` - A space separated list of CSS classes that will be added to the element and spread across the animation. + * * `removeClass` - A space separated list of CSS classes that will be removed from the element and spread across the animation. + * * `duration` - A number value representing the total duration of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `0` + * is provided then the animation will be skipped entirely. + * * `delay` - A number value representing the total delay of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `true` is + * used then whatever delay value is detected from the CSS classes will be mirrored on the elements styles (e.g. by setting delay true then the style value + * of the element will be `transition-delay: DETECTED_VALUE`). Using `true` is useful when you want the CSS classes and inline styles to all share the same + * CSS delay value. + * * `stagger` - A numeric time value representing the delay between successively animated elements + * ({@link ngAnimate#css-staggering-animations Click here to learn how CSS-based staggering works in ngAnimate.}) + * * `staggerIndex` - The numeric index representing the stagger item (e.g. a value of 5 is equal to the sixth item in the stagger; therefore when a + * `stagger` option value of `0.1` is used then there will be a stagger delay of `600ms`) + * * `applyClassesEarly` - Whether or not the classes being added or removed will be used when detecting the animation. This is set by `$animate` when enter/leave/move animations are fired to ensure that the CSS classes are resolved in time. (Note that this will prevent any transitions from occurring on the classes being added and removed.) + * * `cleanupStyles` - Whether or not the provided `from` and `to` styles will be removed once + * the animation is closed. This is useful for when the styles are used purely for the sake of + * the animation and do not have a lasting visual effect on the element (e.g. a collapse and open animation). + * By default this value is set to `false`. + * + * @return {object} an object with start and end methods and details about the animation. + * + * * `start` - The method to start the animation. This will return a `Promise` when called. + * * `end` - This method will cancel the animation and remove all applied CSS classes and styles. + */ + var ONE_SECOND = 1000; - if (options.addClass) { - addRemoveClassName += pendClasses(options.addClass, ADD_CLASS_SUFFIX); - } + var ELAPSED_TIME_MAX_DECIMAL_PLACES = 3; + var CLOSING_TIME_BUFFER = 1.5; - if (options.removeClass) { - if (addRemoveClassName.length) { - addRemoveClassName += ' '; + var DETECT_CSS_PROPERTIES = { + transitionDuration: TRANSITION_DURATION_PROP, + transitionDelay: TRANSITION_DELAY_PROP, + transitionProperty: TRANSITION_PROP + PROPERTY_KEY, + animationDuration: ANIMATION_DURATION_PROP, + animationDelay: ANIMATION_DELAY_PROP, + animationIterationCount: ANIMATION_PROP + ANIMATION_ITERATION_COUNT_KEY + }; + + var DETECT_STAGGER_CSS_PROPERTIES = { + transitionDuration: TRANSITION_DURATION_PROP, + transitionDelay: TRANSITION_DELAY_PROP, + animationDuration: ANIMATION_DURATION_PROP, + animationDelay: ANIMATION_DELAY_PROP + }; + + function getCssKeyframeDurationStyle(duration) { + return [ANIMATION_DURATION_PROP, duration + 's']; + } + + function getCssDelayStyle(delay, isKeyframeAnimation) { + var prop = isKeyframeAnimation ?

Animations are not enabled by default, however, by including `ngAnimate` the animation hooks are enabled for an AngularJS app. - * - * ## Usage - * Simply put, there are two ways to make use of animations when ngAnimate is used: by using **CSS** and **JavaScript**. The former works purely based - * using CSS (by using matching CSS selectors/styles) and the latter triggers animations that are registered via `module.animation()`. For - * both CSS and JS animations the sole requirement is to have a matching `CSS class` that exists both in the registered animation and within - * the HTML element that the animation will be triggered on. - * - * ## Directive Support - * The following directives are "animation aware": - * - * | Directive | Supported Animations | - * |-------------------------------------------------------------------------------|---------------------------------------------------------------------------| - * | {@link ng.directive:form#animations form / ngForm} | add and remove ({@link ng.directive:form#css-classes various classes}) | - * | {@link ngAnimate.directive:ngAnimateSwap#animations ngAnimateSwap} | enter and leave | - * | {@link ng.directive:ngClass#animations ngClass / {{class}​}} | add and remove | - * | {@link ng.directive:ngClassEven#animations ngClassEven} | add and remove | - * | {@link ng.directive:ngClassOdd#animations ngClassOdd} | add and remove | - * | {@link ng.directive:ngHide#animations ngHide} | add and remove (the `ng-hide` class) | - * | {@link ng.directive:ngIf#animations ngIf} | enter and leave | - * | {@link ng.directive:ngInclude#animations ngInclude} | enter and leave | - * | {@link module:ngMessages#animations ngMessage / ngMessageExp} | enter and leave | - * | {@link module:ngMessages#animations ngMessages} | add and remove (the `ng-active`/`ng-inactive` classes) | - * | {@link ng.directive:ngModel#animations ngModel} | add and remove ({@link ng.directive:ngModel#css-classes various classes}) | - * | {@link ng.directive:ngRepeat#animations ngRepeat} | enter, leave, and move | - * | {@link ng.directive:ngShow#animations ngShow} | add and remove (the `ng-hide` class) | - * | {@link ng.directive:ngSwitch#animations ngSwitch} | enter and leave | - * | {@link ngRoute.directive:ngView#animations ngView} | enter and leave | - * - * (More information can be found by visiting the documentation associated with each directive.) - * - * For a full breakdown of the steps involved during each animation event, refer to the - * {@link ng.$animate `$animate` API docs}. - * - * ## CSS-based Animations - * - * CSS-based animations with ngAnimate are unique since they require no JavaScript code at all. By using a CSS class that we reference between our HTML - * and CSS code we can create an animation that will be picked up by AngularJS when an underlying directive performs an operation. - * - * The example below shows how an `enter` animation can be made possible on an element using `ng-if`: - * - * ```html - *
- * Fade me in out - *
- * - * - * ``` - * - * Notice the CSS class **fade**? We can now create the CSS transition code that references this class: - * - * ```css - * /* The starting CSS styles for the enter animation */ - * .fade.ng-enter { - * transition:0.5s linear all; - * opacity:0; - * } - * - * /* The finishing CSS styles for the enter animation */ - * .fade.ng-enter.ng-enter-active { - * opacity:1; - * } - * ``` - * - * The key thing to remember here is that, depending on the animation event (which each of the directives above trigger depending on what's going on) two - * generated CSS classes will be applied to the element; in the example above we have `.ng-enter` and `.ng-enter-active`. For CSS transitions, the transition - * code **must** be defined within the starting CSS class (in this case `.ng-enter`). The destination class is what the transition will animate towards. - * - * If for example we wanted to create animations for `leave` and `move` (ngRepeat triggers move) then we can do so using the same CSS naming conventions: - * - * ```css - * /* now the element will fade out before it is removed from the DOM */ - * .fade.ng-leave { - * transition:0.5s linear all; - * opacity:1; - * } - * .fade.ng-leave.ng-leave-active { - * opacity:0; - * } - * ``` - * - * We can also make use of **CSS Keyframes** by referencing the keyframe animation within the starting CSS class: - * - * ```css - * /* there is no need to define anything inside of the destination - * CSS class since the keyframe will take charge of the animation */ - * .fade.ng-leave { - * animation: my_fade_animation 0.5s linear; - * -webkit-animation: my_fade_animation 0.5s linear; - * } - * - * @keyframes my_fade_animation { - * from { opacity:1; } - * to { opacity:0; } - * } - * - * @-webkit-keyframes my_fade_animation { - * from { opacity:1; } - * to { opacity:0; } - * } - * ``` - * - * Feel free also mix transitions and keyframes together as well as any other CSS classes on the same element. - * - * ### CSS Class-based Animations - * - * Class-based animations (animations that are triggered via `ngClass`, `ngShow`, `ngHide` and some other directives) have a slightly different - * naming convention. Class-based animations are basic enough that a standard transition or keyframe can be referenced on the class being added - * and removed. - * - * For example if we wanted to do a CSS animation for `ngHide` then we place an animation on the `.ng-hide` CSS class: - * - * ```html - *
- * Show and hide me - *
- * - * - * - * ``` - * - * All that is going on here with ngShow/ngHide behind the scenes is the `.ng-hide` class is added/removed (when the hidden state is valid). Since - * ngShow and ngHide are animation aware then we can match up a transition and ngAnimate handles the rest. - * - * In addition the addition and removal of the CSS class, ngAnimate also provides two helper methods that we can use to further decorate the animation - * with CSS styles. - * - * ```html - *
- * Highlight this box - *
- * - * - * - * ``` - * - * We can also make use of CSS keyframes by placing them within the CSS classes. - * - * - * ### CSS Staggering Animations - * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a - * curtain-like effect. The ngAnimate module (versions >=1.2) supports staggering animations and the stagger effect can be - * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for - * the animation. The style property expected within the stagger class can either be a **transition-delay** or an - * **animation-delay** property (or both if your animation contains both transitions and keyframe animations). - * - * ```css - * .my-animation.ng-enter { - * /* standard transition code */ - * transition: 1s linear all; - * opacity:0; - * } - * .my-animation.ng-enter-stagger { - * /* this will have a 100ms delay between each successive leave animation */ - * transition-delay: 0.1s; - * - * /* As of 1.4.4, this must always be set: it signals ngAnimate - * to not accidentally inherit a delay property from another CSS class */ - * transition-duration: 0s; - * - * /* if you are using animations instead of transitions you should configure as follows: - * animation-delay: 0.1s; - * animation-duration: 0s; */ - * } - * .my-animation.ng-enter.ng-enter-active { - * /* standard transition styles */ - * opacity:1; - * } - * ``` - * - * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations - * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this - * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation - * will also be reset if one or more animation frames have passed since the multiple calls to `$animate` were fired. - * - * The following code will issue the **ng-leave-stagger** event on the element provided: - * - * ```js - * var kids = parent.children(); - * - * $animate.leave(kids[0]); //stagger index=0 - * $animate.leave(kids[1]); //stagger index=1 - * $animate.leave(kids[2]); //stagger index=2 - * $animate.leave(kids[3]); //stagger index=3 - * $animate.leave(kids[4]); //stagger index=4 - * - * window.requestAnimationFrame(function() { - * //stagger has reset itself - * $animate.leave(kids[5]); //stagger index=0 - * $animate.leave(kids[6]); //stagger index=1 - * - * $scope.$digest(); - * }); - * ``` - * - * Stagger animations are currently only supported within CSS-defined animations. - * - * ### The `ng-animate` CSS class - * - * When ngAnimate is animating an element it will apply the `ng-animate` CSS class to the element for the duration of the animation. - * This is a temporary CSS class and it will be removed once the animation is over (for both JavaScript and CSS-based animations). - * - * Therefore, animations can be applied to an element using this temporary class directly via CSS. - * - * ```css - * .zipper.ng-animate { - * transition:0.5s linear all; - * } - * .zipper.ng-enter { - * opacity:0; - * } - * .zipper.ng-enter.ng-enter-active { - * opacity:1; - * } - * .zipper.ng-leave { - * opacity:1; - * } - * .zipper.ng-leave.ng-leave-active { - * opacity:0; - * } - * ``` - * - * (Note that the `ng-animate` CSS class is reserved and it cannot be applied on an element directly since ngAnimate will always remove - * the CSS class once an animation has completed.) - * - * - * ### The `ng-[event]-prepare` class - * - * This is a special class that can be used to prevent unwanted flickering / flash of content before - * the actual animation starts. The class is added as soon as an animation is initialized, but removed - * before the actual animation starts (after waiting for a $digest). - * It is also only added for *structural* animations (`enter`, `move`, and `leave`). - * - * In practice, flickering can appear when nesting elements with structural animations such as `ngIf` - * into elements that have class-based animations such as `ngClass`. - * - * ```html - *
- *
- *
- *
- *
- * ``` - * - * It is possible that during the `enter` animation, the `.message` div will be briefly visible before it starts animating. - * In that case, you can add styles to the CSS that make sure the element stays hidden before the animation starts: - * - * ```css - * .message.ng-enter-prepare { - * opacity: 0; - * } - * ``` - * - * ### Animating between value changes - * - * Sometimes you need to animate between different expression states, whose values - * don't necessary need to be known or referenced in CSS styles. - * Unless possible with another {@link ngAnimate#directive-support "animation aware" directive}, - * that specific use case can always be covered with {@link ngAnimate.directive:ngAnimateSwap} as - * can be seen in {@link ngAnimate.directive:ngAnimateSwap#examples this example}. - * - * Note that {@link ngAnimate.directive:ngAnimateSwap} is a *structural directive*, which means it - * creates a new instance of the element (including any other/child directives it may have) and - * links it to a new scope every time *swap* happens. In some cases this might not be desirable - * (e.g. for performance reasons, or when you wish to retain internal state on the original - * element instance). - * - * ## JavaScript-based Animations - * - * ngAnimate also allows for animations to be consumed by JavaScript code. The approach is similar to CSS-based animations (where there is a shared - * CSS class that is referenced in our HTML code) but in addition we need to register the JavaScript animation on the module. By making use of the - * `module.animation()` module function we can register the animation. - * - * Let's see an example of a enter/leave animation using `ngRepeat`: - * - * ```html - *
- * {{ item }} - *
- * ``` - * - * See the **slide** CSS class? Let's use that class to define an animation that we'll structure in our module code by using `module.animation`: - * - * ```js - * myModule.animation('.slide', [function() { - * return { - * // make note that other events (like addClass/removeClass) - * // have different function input parameters - * enter: function(element, doneFn) { - * jQuery(element).fadeIn(1000, doneFn); - * - * // remember to call doneFn so that AngularJS - * // knows that the animation has concluded - * }, - * - * move: function(element, doneFn) { - * jQuery(element).fadeIn(1000, doneFn); - * }, - * - * leave: function(element, doneFn) { - * jQuery(element).fadeOut(1000, doneFn); - * } - * } - * }]); - * ``` - * - * The nice thing about JS-based animations is that we can inject other services and make use of advanced animation libraries such as - * greensock.js and velocity.js. - * - * If our animation code class-based (meaning that something like `ngClass`, `ngHide` and `ngShow` triggers it) then we can still define - * our animations inside of the same registered animation, however, the function input arguments are a bit different: - * - * ```html - *
- * this box is moody - *
- * - * - * - * ``` - * - * ```js - * myModule.animation('.colorful', [function() { - * return { - * addClass: function(element, className, doneFn) { - * // do some cool animation and call the doneFn - * }, - * removeClass: function(element, className, doneFn) { - * // do some cool animation and call the doneFn - * }, - * setClass: function(element, addedClass, removedClass, doneFn) { - * // do some cool animation and call the doneFn - * } - * } - * }]); - * ``` - * - * ## CSS + JS Animations Together - * - * AngularJS 1.4 and higher has taken steps to make the amalgamation of CSS and JS animations more flexible. However, unlike earlier versions of AngularJS, - * defining CSS and JS animations to work off of the same CSS class will not work anymore. Therefore the example below will only result in **JS animations taking - * charge of the animation**: - * - * ```html - *
- * Slide in and out - *
- * ``` - * - * ```js - * myModule.animation('.slide', [function() { - * return { - * enter: function(element, doneFn) { - * jQuery(element).slideIn(1000, doneFn); - * } - * } - * }]); - * ``` - * - * ```css - * .slide.ng-enter { - * transition:0.5s linear all; - * transform:translateY(-100px); - * } - * .slide.ng-enter.ng-enter-active { - * transform:translateY(0); - * } - * ``` - * - * Does this mean that CSS and JS animations cannot be used together? Do JS-based animations always have higher priority? We can make up for the - * lack of CSS animations by using the `$animateCss` service to trigger our own tweaked-out, CSS-based animations directly from - * our own JS-based animation code: - * - * ```js - * myModule.animation('.slide', ['$animateCss', function($animateCss) { - * return { - * enter: function(element) { -* // this will trigger `.slide.ng-enter` and `.slide.ng-enter-active`. - * return $animateCss(element, { - * event: 'enter', - * structural: true - * }); - * } - * } - * }]); - * ``` - * - * The nice thing here is that we can save bandwidth by sticking to our CSS-based animation code and we don't need to rely on a 3rd-party animation framework. - * - * The `$animateCss` service is very powerful since we can feed in all kinds of extra properties that will be evaluated and fed into a CSS transition or - * keyframe animation. For example if we wanted to animate the height of an element while adding and removing classes then we can do so by providing that - * data into `$animateCss` directly: - * - * ```js - * myModule.animation('.slide', ['$animateCss', function($animateCss) { - * return { - * enter: function(element) { - * return $animateCss(element, { - * event: 'enter', - * structural: true, - * addClass: 'maroon-setting', - * from: { height:0 }, - * to: { height: 200 } - * }); - * } - * } - * }]); - * ``` - * - * Now we can fill in the rest via our transition CSS code: - * - * ```css - * /* the transition tells ngAnimate to make the animation happen */ - * .slide.ng-enter { transition:0.5s linear all; } - * - * /* this extra CSS class will be absorbed into the transition - * since the $animateCss code is adding the class */ - * .maroon-setting { background:red; } - * ``` - * - * And `$animateCss` will figure out the rest. Just make sure to have the `done()` callback fire the `doneFn` function to signal when the animation is over. - * - * To learn more about what's possible be sure to visit the {@link ngAnimate.$animateCss $animateCss service}. - * - * ## Animation Anchoring (via `ng-animate-ref`) - * - * ngAnimate in AngularJS 1.4 comes packed with the ability to cross-animate elements between - * structural areas of an application (like views) by pairing up elements using an attribute - * called `ng-animate-ref`. - * - * Let's say for example we have two views that are managed by `ng-view` and we want to show - * that there is a relationship between two components situated in within these views. By using the - * `ng-animate-ref` attribute we can identify that the two components are paired together and we - * can then attach an animation, which is triggered when the view changes. - * - * Say for example we have the following template code: - * - * ```html - * - *
- *
- * - * - * - * - * - * - * - * - * ``` - * - * Now, when the view changes (once the link is clicked), ngAnimate will examine the - * HTML contents to see if there is a match reference between any components in the view - * that is leaving and the view that is entering. It will scan both the view which is being - * removed (leave) and inserted (enter) to see if there are any paired DOM elements that - * contain a matching ref value. - * - * The two images match since they share the same ref value. ngAnimate will now create a - * transport element (which is a clone of the first image element) and it will then attempt - * to animate to the position of the second image element in the next view. For the animation to - * work a special CSS class called `ng-anchor` will be added to the transported element. - * - * We can now attach a transition onto the `.banner.ng-anchor` CSS class and then - * ngAnimate will handle the entire transition for us as well as the addition and removal of - * any changes of CSS classes between the elements: - * - * ```css - * .banner.ng-anchor { - * /* this animation will last for 1 second since there are - * two phases to the animation (an `in` and an `out` phase) */ - * transition:0.5s linear all; - * } - * ``` - * - * We also **must** include animations for the views that are being entered and removed - * (otherwise anchoring wouldn't be possible since the new view would be inserted right away). - * - * ```css - * .view-animation.ng-enter, .view-animation.ng-leave { - * transition:0.5s linear all; - * position:fixed; - * left:0; - * top:0; - * width:100%; - * } - * .view-animation.ng-enter { - * transform:translateX(100%); - * } - * .view-animation.ng-leave, - * .view-animation.ng-enter.ng-enter-active { - * transform:translateX(0%); - * } - * .view-animation.ng-leave.ng-leave-active { - * transform:translateX(-100%); - * } - * ``` - * - * Now we can jump back to the anchor animation. When the animation happens, there are two stages that occur: - * an `out` and an `in` stage. The `out` stage happens first and that is when the element is animated away - * from its origin. Once that animation is over then the `in` stage occurs which animates the - * element to its destination. The reason why there are two animations is to give enough time - * for the enter animation on the new element to be ready. - * - * The example above sets up a transition for both the in and out phases, but we can also target the out or - * in phases directly via `ng-anchor-out` and `ng-anchor-in`. - * - * ```css - * .banner.ng-anchor-out { - * transition: 0.5s linear all; - * - * /* the scale will be applied during the out animation, - * but will be animated away when the in animation runs */ - * transform: scale(1.2); - * } - * - * .banner.ng-anchor-in { - * transition: 1s linear all; - * } - * ``` - * - * - * - * - * ### Anchoring Demo - * - - - Home -

The cloned element will be placed inside of the root element - * of the application (where ng-app was defined) and all of the CSS classes of the starting element will be applied. The - * element will then animate into the `out` and `in` animations and will eventually reach the coordinates and match - * the dimensions of the destination element. During the entire animation a CSS class of `.ng-animate-shim` will be applied - * to both the starting and destination elements in order to hide them from being visible (the CSS styling for the class - * is: `visibility:hidden`). Once the anchor reaches its destination then it will be removed and the destination element - * will become visible since the shim class will be removed. - * - * ### How is the morphing handled? - * - * CSS Anchoring relies on transitions and keyframes and the internal code is intelligent enough to figure out - * what CSS classes differ between the starting element and the destination element. These different CSS classes - * will be added/removed on the anchor element and a transition will be applied (the transition that is provided - * in the anchor class). Long story short, ngAnimate will figure out what classes to add and remove which will - * make the transition of the element as smooth and automatic as possible. Be sure to use simple CSS classes that - * do not rely on DOM nesting structure so that the anchor element appears the same as the starting element (since - * the cloned element is placed inside of root element which is likely close to the body element). - * - * Note that if the root element is on the `` element then the cloned node will be placed inside of body. - * - * - * ## Using $animate in your directive code - * - * So far we've explored how to feed in animations into an AngularJS application, but how do we trigger animations within our own directives in our application? - * By injecting the `$animate` service into our directive code, we can trigger structural and class-based hooks which can then be consumed by animations. Let's - * imagine we have a greeting box that shows and hides itself when the data changes - * - * ```html - * Hi there - * ``` - * - * ```js - * ngModule.directive('greetingBox', ['$animate', function($animate) { - * return function(scope, element, attrs) { - * attrs.$observe('active', function(value) { - * value ? $animate.addClass(element, 'on') : $animate.removeClass(element, 'on'); - * }); - * }); - * }]); - * ``` - * - * Now the `on` CSS class is added and removed on the greeting box component. Now if we add a CSS class on top of the greeting box element - * in our HTML code then we can trigger a CSS or JS animation to happen. - * - * ```css - * /* normally we would create a CSS class to reference on the element */ - * greeting-box.on { transition:0.5s linear all; background:green; color:white; } - * ``` - * - * The `$animate` service contains a variety of other methods like `enter`, `leave`, `animate` and `setClass`. To learn more about what's - * possible be sure to visit the {@link ng.$animate $animate service API page}. - * - * - * ## Callbacks and Promises - * - * When `$animate` is called it returns a promise that can be used to capture when the animation has ended. Therefore if we were to trigger - * an animation (within our directive code) then we can continue performing directive and scope related activities after the animation has - * ended by chaining onto the returned promise that animation method returns. - * - * ```js - * // somewhere within the depths of the directive - * $animate.enter(element, parent).then(function() { - * //the animation has completed - * }); - * ``` - * - * (Note that earlier versions of AngularJS prior to v1.4 required the promise code to be wrapped using `$scope.$apply(...)`. This is not the case - * anymore.) - * - * In addition to the animation promise, we can also make use of animation-related callbacks within our directives and controller code by registering - * an event listener using the `$animate` service. Let's say for example that an animation was triggered on our view - * routing controller to hook into that: - * - * ```js - * ngModule.controller('HomePageController', ['$animate', function($animate) { - * $animate.on('enter', ngViewElement, function(element) { - * // the animation for this route has completed - * }]); - * }]) - * ``` - * - * (Note that you will need to trigger a digest within the callback to get AngularJS to notice any scope-related changes.) - */ - -var copy; -var extend; -var forEach; -var isArray; -var isDefined; -var isElement; -var isFunction; -var isObject; -var isString; -var isUndefined; -var jqLite; -var noop; - -/** - * @ngdoc service - * @name $animate - * @kind object - * - * @description - * The ngAnimate `$animate` service documentation is the same for the core `$animate` service. - * - * Click here {@link ng.$animate to learn more about animations with `$animate`}. - */ -angular.module('ngAnimate', [], function initAngularHelpers() { - // Access helpers from AngularJS core. - // Do it inside a `config` block to ensure `window.angular` is available. - noop = angular.noop; - copy = angular.copy; - extend = angular.extend; - jqLite = angular.element; - forEach = angular.forEach; - isArray = angular.isArray; - isString = angular.isString; - isObject = angular.isObject; - isUndefined = angular.isUndefined; - isDefined = angular.isDefined; - isFunction = angular.isFunction; - isElement = angular.isElement; -}) - .info({ angularVersion: '1.7.3' }) - .directive('ngAnimateSwap', ngAnimateSwapDirective) - - .directive('ngAnimateChildren', $$AnimateChildrenDirective) - .factory('$$rAFScheduler', $$rAFSchedulerFactory) - - .provider('$$animateQueue', $$AnimateQueueProvider) - .provider('$$animateCache', $$AnimateCacheProvider) - .provider('$$animation', $$AnimationProvider) - - .provider('$animateCss', $AnimateCssProvider) - .provider('$$animateCssDriver', $$AnimateCssDriverProvider) - - .provider('$$animateJs', $$AnimateJsProvider) - .provider('$$animateJsDriver', $$AnimateJsDriverProvider); - - -})(window, window.angular); - -},{}],638:[function(require,module,exports){ -require('./angular-animate'); -module.exports = 'ngAnimate'; - -},{"./angular-animate":637}],639:[function(require,module,exports){ -/** - * @license AngularJS v1.7.3 - * (c) 2010-2018 Google, Inc. http://angularjs.org - * License: MIT - */ -(function(window, angular) {'use strict'; - -/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * - * Any commits to this file should be reviewed with security in mind. * - * Changes to this file can potentially create security vulnerabilities. * - * An approval from 2 Core members with history of modifying * - * this file is required. * - * * - * Does the change somehow allow for arbitrary javascript to be executed? * - * Or allows for someone to change the prototype of built-in objects? * - * Or gives undesired access to variables likes document or window? * - * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * */ - -var $sanitizeMinErr = angular.$$minErr('$sanitize'); -var bind; -var extend; -var forEach; -var isArray; -var isDefined; -var lowercase; -var noop; -var nodeContains; -var htmlParser; -var htmlSanitizeWriter; - -/** - * @ngdoc module - * @name ngSanitize - * @description - * - * The `ngSanitize` module provides functionality to sanitize HTML. - * - * See {@link ngSanitize.$sanitize `$sanitize`} for usage. - */ - -/** - * @ngdoc service - * @name $sanitize - * @kind function - * - * @description - * Sanitizes an html string by stripping all potentially dangerous tokens. - * - * The input is sanitized by parsing the HTML into tokens.

By enabling this setting without taking other precautions, you might expose your - * application to click-hijacking attacks. In these attacks, sanitized svg elements could be positioned - * outside of the containing element and be rendered over other elements on the page (e.g. a login - * link). Such behavior can then result in phishing incidents.

+ * The `ngAnimate` module provides support for CSS-based animations (keyframes and transitions) as well as JavaScript-based animations via + * callback hooks. Animations are not enabled by default, however, by including `ngAnimate` the animation hooks are enabled for an AngularJS app. + * + * ## Usage + * Simply put, there are two ways to make use of animations when ngAnimate is used: by using **CSS** and **JavaScript**. The former works purely based + * using CSS (by using matching CSS selectors/styles) and the latter triggers animations that are registered via `module.animation()`. For + * both CSS and JS animations the sole requirement is to have a matching `CSS class` that exists both in the registered animation and within + * the HTML element that the animation will be triggered on. + * + * ## Directive Support + * The following directives are "animation aware": + * + * | Directive | Supported Animations | + * |-------------------------------------------------------------------------------|---------------------------------------------------------------------------| + * | {@link ng.directive:form#animations form / ngForm} | add and remove ({@link ng.directive:form#css-classes various classes}) | + * | {@link ngAnimate.directive:ngAnimateSwap#animations ngAnimateSwap} | enter and leave | + * | {@link ng.directive:ngClass#animations ngClass / {{class}​}} | add and remove | + * | {@link ng.directive:ngClassEven#animations ngClassEven} | add and remove | + * | {@link ng.directive:ngClassOdd#animations ngClassOdd} | add and remove | + * | {@link ng.directive:ngHide#animations ngHide} | add and remove (the `ng-hide` class) | + * | {@link ng.directive:ngIf#animations ngIf} | enter and leave | + * | {@link ng.directive:ngInclude#animations ngInclude} | enter and leave | + * | {@link module:ngMessages#animations ngMessage / ngMessageExp} | enter and leave | + * | {@link module:ngMessages#animations ngMessages} | add and remove (the `ng-active`/`ng-inactive` classes) | + * | {@link ng.directive:ngModel#animations ngModel} | add and remove ({@link ng.directive:ngModel#css-classes various classes}) | + * | {@link ng.directive:ngRepeat#animations ngRepeat} | enter, leave, and move | + * | {@link ng.directive:ngShow#animations ngShow} | add and remove (the `ng-hide` class) | + * | {@link ng.directive:ngSwitch#animations ngSwitch} | enter and leave | + * | {@link ngRoute.directive:ngView#animations ngView} | enter and leave | + * + * (More information can be found by visiting the documentation associated with each directive.) + * + * For a full breakdown of the steps involved during each animation event, refer to the + * {@link ng.$animate `$animate` API docs}. + * + * ## CSS-based Animations + * + * CSS-based animations with ngAnimate are unique since they require no JavaScript code at all. By using a CSS class that we reference between our HTML + * and CSS code we can create an animation that will be picked up by AngularJS when an underlying directive performs an operation. + * + * The example below shows how an `enter` animation can be made possible on an element using `ng-if`: + * + * ```html + *
+ * Fade me in out + *
+ * + * + * ``` * - *

To protect against these, explicitly setup `overflow: hidden` css rule for all potential svg - * tags within the sanitized content:

+ * Notice the CSS class **fade**? We can now create the CSS transition code that references this class: * - *
+ * ```css + * /* The starting CSS styles for the enter animation */ + * .fade.ng-enter { + * transition:0.5s linear all; + * opacity:0; + * } * - * 

-   *   .rootOfTheIncludedContent svg {
-   *     overflow: hidden !important;
-   *   }
-   *
+ * /* The finishing CSS styles for the enter animation */ + * .fade.ng-enter.ng-enter-active { + * opacity:1; + * } + * ``` + * + * The key thing to remember here is that, depending on the animation event (which each of the directives above trigger depending on what's going on) two + * generated CSS classes will be applied to the element; in the example above we have `.ng-enter` and `.ng-enter-active`. For CSS transitions, the transition + * code **must** be defined within the starting CSS class (in this case `.ng-enter`). The destination class is what the transition will animate towards. + * + * If for example we wanted to create animations for `leave` and `move` (ngRepeat triggers move) then we can do so using the same CSS naming conventions: + * + * ```css + * /* now the element will fade out before it is removed from the DOM */ + * .fade.ng-leave { + * transition:0.5s linear all; + * opacity:1; + * } + * .fade.ng-leave.ng-leave-active { + * opacity:0; + * } + * ``` + * + * We can also make use of **CSS Keyframes** by referencing the keyframe animation within the starting CSS class: + * + * ```css + * /* there is no need to define anything inside of the destination + * CSS class since the keyframe will take charge of the animation */ + * .fade.ng-leave { + * animation: my_fade_animation 0.5s linear; + * -webkit-animation: my_fade_animation 0.5s linear; + * } + * + * @keyframes my_fade_animation { + * from { opacity:1; } + * to { opacity:0; } + * } + * + * @-webkit-keyframes my_fade_animation { + * from { opacity:1; } + * to { opacity:0; } + * } + * ``` + * + * Feel free also mix transitions and keyframes together as well as any other CSS classes on the same element. + * + * ### CSS Class-based Animations + * + * Class-based animations (animations that are triggered via `ngClass`, `ngShow`, `ngHide` and some other directives) have a slightly different + * naming convention. Class-based animations are basic enough that a standard transition or keyframe can be referenced on the class being added + * and removed. + * + * For example if we wanted to do a CSS animation for `ngHide` then we place an animation on the `.ng-hide` CSS class: + * + * ```html + *
+ * Show and hide me *
+ * * - * @param {boolean=} flag Enable or disable SVG support in the sanitizer. - * @returns {boolean|$sanitizeProvider} Returns the currently configured value if called - * without an argument or self for chaining otherwise. - */ - this.enableSvg = function(enableSvg) { - if (isDefined(enableSvg)) { - svgEnabled = enableSvg; - return this; - } else { - return svgEnabled; - } - }; - - - /** - * @ngdoc method - * @name $sanitizeProvider#addValidElements - * @kind function + * + * ``` * - * @description - * Extends the built-in lists of valid HTML/SVG elements, i.e. elements that are considered safe - * and are not stripped off during sanitization. You can extend the following lists of elements: + * All that is going on here with ngShow/ngHide behind the scenes is the `.ng-hide` class is added/removed (when the hidden state is valid). Since + * ngShow and ngHide are animation aware then we can match up a transition and ngAnimate handles the rest. + * + * In addition the addition and removal of the CSS class, ngAnimate also provides two helper methods that we can use to further decorate the animation + * with CSS styles. + * + * ```html + *
+ * Highlight this box + *
+ * + * + * + * ``` * - * - `htmlElements`: A list of elements (tag names) to extend the current list of safe HTML - * elements. HTML elements considered safe will not be removed during sanitization. All other - * elements will be stripped off. + * We can also make use of CSS keyframes by placing them within the CSS classes. * - * - `htmlVoidElements`: This is similar to `htmlElements`, but marks the elements as - * "void elements" (similar to HTML - * [void elements](https://rawgit.com/w3c/html/html5.1-2/single-page.html#void-elements)). These - * elements have no end tag and cannot have content. * - * - `svgElements`: This is similar to `htmlElements`, but for SVG elements. This list is only - * taken into account if SVG is {@link ngSanitize.$sanitizeProvider#enableSvg enabled} for - * `$sanitize`. + * ### CSS Staggering Animations + * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a + * curtain-like effect. The ngAnimate module (versions >=1.2) supports staggering animations and the stagger effect can be + * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for + * the animation. The style property expected within the stagger class can either be a **transition-delay** or an + * **animation-delay** property (or both if your animation contains both transitions and keyframe animations). * - *
- * This method must be called during the {@link angular.Module#config config} phase. Once the - * `$sanitize` service has been instantiated, this method has no effect. + * ```css + * .my-animation.ng-enter { + * /* standard transition code */ + * transition: 1s linear all; + * opacity:0; + * } + * .my-animation.ng-enter-stagger { + * /* this will have a 100ms delay between each successive leave animation */ + * transition-delay: 0.1s; + * + * /* As of 1.4.4, this must always be set: it signals ngAnimate + * to not accidentally inherit a delay property from another CSS class */ + * transition-duration: 0s; + * + * /* if you are using animations instead of transitions you should configure as follows: + * animation-delay: 0.1s; + * animation-duration: 0s; */ + * } + * .my-animation.ng-enter.ng-enter-active { + * /* standard transition styles */ + * opacity:1; + * } + * ``` + * + * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations + * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this + * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation + * will also be reset if one or more animation frames have passed since the multiple calls to `$animate` were fired. + * + * The following code will issue the **ng-leave-stagger** event on the element provided: + * + * ```js + * var kids = parent.children(); + * + * $animate.leave(kids[0]); //stagger index=0 + * $animate.leave(kids[1]); //stagger index=1 + * $animate.leave(kids[2]); //stagger index=2 + * $animate.leave(kids[3]); //stagger index=3 + * $animate.leave(kids[4]); //stagger index=4 + * + * window.requestAnimationFrame(function() { + * //stagger has reset itself + * $animate.leave(kids[5]); //stagger index=0 + * $animate.leave(kids[6]); //stagger index=1 + * + * $scope.$digest(); + * }); + * ``` + * + * Stagger animations are currently only supported within CSS-defined animations. + * + * ### The `ng-animate` CSS class + * + * When ngAnimate is animating an element it will apply the `ng-animate` CSS class to the element for the duration of the animation. + * This is a temporary CSS class and it will be removed once the animation is over (for both JavaScript and CSS-based animations). + * + * Therefore, animations can be applied to an element using this temporary class directly via CSS. + * + * ```css + * .zipper.ng-animate { + * transition:0.5s linear all; + * } + * .zipper.ng-enter { + * opacity:0; + * } + * .zipper.ng-enter.ng-enter-active { + * opacity:1; + * } + * .zipper.ng-leave { + * opacity:1; + * } + * .zipper.ng-leave.ng-leave-active { + * opacity:0; + * } + * ``` + * + * (Note that the `ng-animate` CSS class is reserved and it cannot be applied on an element directly since ngAnimate will always remove + * the CSS class once an animation has completed.) + * + * + * ### The `ng-[event]-prepare` class + * + * This is a special class that can be used to prevent unwanted flickering / flash of content before + * the actual animation starts. The class is added as soon as an animation is initialized, but removed + * before the actual animation starts (after waiting for a $digest). + * It is also only added for *structural* animations (`enter`, `move`, and `leave`). + * + * In practice, flickering can appear when nesting elements with structural animations such as `ngIf` + * into elements that have class-based animations such as `ngClass`. + * + * ```html + *
+ *
+ *
+ *
*
+ * ``` * - *
- * Keep in mind that extending the built-in lists of elements may expose your app to XSS or - * other vulnerabilities. Be very mindful of the elements you add. + * It is possible that during the `enter` animation, the `.message` div will be briefly visible before it starts animating. + * In that case, you can add styles to the CSS that make sure the element stays hidden before the animation starts: + * + * ```css + * .message.ng-enter-prepare { + * opacity: 0; + * } + * ``` + * + * ### Animating between value changes + * + * Sometimes you need to animate between different expression states, whose values + * don't necessary need to be known or referenced in CSS styles. + * Unless possible with another {@link ngAnimate#directive-support "animation aware" directive}, + * that specific use case can always be covered with {@link ngAnimate.directive:ngAnimateSwap} as + * can be seen in {@link ngAnimate.directive:ngAnimateSwap#examples this example}. + * + * Note that {@link ngAnimate.directive:ngAnimateSwap} is a *structural directive*, which means it + * creates a new instance of the element (including any other/child directives it may have) and + * links it to a new scope every time *swap* happens. In some cases this might not be desirable + * (e.g. for performance reasons, or when you wish to retain internal state on the original + * element instance). + * + * ## JavaScript-based Animations + * + * ngAnimate also allows for animations to be consumed by JavaScript code. The approach is similar to CSS-based animations (where there is a shared + * CSS class that is referenced in our HTML code) but in addition we need to register the JavaScript animation on the module. By making use of the + * `module.animation()` module function we can register the animation. + * + * Let's see an example of a enter/leave animation using `ngRepeat`: + * + * ```html + *
+ * {{ item }} *
+ * ``` * - * @param {Array|Object} elements - A list of valid HTML elements or an object with one or - * more of the following properties: - * - **htmlElements** - `{Array}` - A list of elements to extend the current list of - * HTML elements. - * - **htmlVoidElements** - `{Array}` - A list of elements to extend the current list of - * void HTML elements; i.e. elements that do not have an end tag. - * - **svgElements** - `{Array}` - A list of elements to extend the current list of SVG - * elements. The list of SVG elements is only taken into account if SVG is - * {@link ngSanitize.$sanitizeProvider#enableSvg enabled} for `$sanitize`. + * See the **slide** CSS class? Let's use that class to define an animation that we'll structure in our module code by using `module.animation`: * - * Passing an array (`[...]`) is equivalent to passing `{htmlElements: [...]}`. + * ```js + * myModule.animation('.slide', [function() { + * return { + * // make note that other events (like addClass/removeClass) + * // have different function input parameters + * enter: function(element, doneFn) { + * jQuery(element).fadeIn(1000, doneFn); * - * @return {$sanitizeProvider} Returns self for chaining. - */ - this.addValidElements = function(elements) { - if (!hasBeenInstantiated) { - if (isArray(elements)) { - elements = {htmlElements: elements}; - } - - addElementsTo(svgElements, elements.svgElements); - addElementsTo(voidElements, elements.htmlVoidElements); - addElementsTo(validElements, elements.htmlVoidElements); - addElementsTo(validElements, elements.htmlElements); - } - - return this; - }; - - - /** - * @ngdoc method - * @name $sanitizeProvider#addValidAttrs - * @kind function + * // remember to call doneFn so that AngularJS + * // knows that the animation has concluded + * }, * - * @description - * Extends the built-in list of valid attributes, i.e. attributes that are considered safe and are - * not stripped off during sanitization. + * move: function(element, doneFn) { + * jQuery(element).fadeIn(1000, doneFn); + * }, + * + * leave: function(element, doneFn) { + * jQuery(element).fadeOut(1000, doneFn); + * } + * } + * }]); + * ``` * - * **Note**: - * The new attributes will not be treated as URI attributes, which means their values will not be - * sanitized as URIs using `$compileProvider`'s - * {@link ng.$compileProvider#aHrefSanitizationWhitelist aHrefSanitizationWhitelist} and - * {@link ng.$compileProvider#imgSrcSanitizationWhitelist imgSrcSanitizationWhitelist}. + * The nice thing about JS-based animations is that we can inject other services and make use of advanced animation libraries such as + * greensock.js and velocity.js. * - *
- * This method must be called during the {@link angular.Module#config config} phase. Once the - * `$sanitize` service has been instantiated, this method has no effect. + * If our animation code class-based (meaning that something like `ngClass`, `ngHide` and `ngShow` triggers it) then we can still define + * our animations inside of the same registered animation, however, the function input arguments are a bit different: + * + * ```html + *
+ * this box is moody *
+ * + * + * + * ``` * - *
- * Keep in mind that extending the built-in list of attributes may expose your app to XSS or - * other vulnerabilities. Be very mindful of the attributes you add. + * ```js + * myModule.animation('.colorful', [function() { + * return { + * addClass: function(element, className, doneFn) { + * // do some cool animation and call the doneFn + * }, + * removeClass: function(element, className, doneFn) { + * // do some cool animation and call the doneFn + * }, + * setClass: function(element, addedClass, removedClass, doneFn) { + * // do some cool animation and call the doneFn + * } + * } + * }]); + * ``` + * + * ## CSS + JS Animations Together + * + * AngularJS 1.4 and higher has taken steps to make the amalgamation of CSS and JS animations more flexible. However, unlike earlier versions of AngularJS, + * defining CSS and JS animations to work off of the same CSS class will not work anymore. Therefore the example below will only result in **JS animations taking + * charge of the animation**: + * + * ```html + *
+ * Slide in and out + *
+ * ``` + * + * ```js + * myModule.animation('.slide', [function() { + * return { + * enter: function(element, doneFn) { + * jQuery(element).slideIn(1000, doneFn); + * } + * } + * }]); + * ``` + * + * ```css + * .slide.ng-enter { + * transition:0.5s linear all; + * transform:translateY(-100px); + * } + * .slide.ng-enter.ng-enter-active { + * transform:translateY(0); + * } + * ``` + * + * Does this mean that CSS and JS animations cannot be used together? Do JS-based animations always have higher priority? We can make up for the + * lack of CSS animations by using the `$animateCss` service to trigger our own tweaked-out, CSS-based animations directly from + * our own JS-based animation code: + * + * ```js + * myModule.animation('.slide', ['$animateCss', function($animateCss) { + * return { + * enter: function(element) { + * // this will trigger `.slide.ng-enter` and `.slide.ng-enter-active`. + * return $animateCss(element, { + * event: 'enter', + * structural: true + * }); + * } + * } + * }]); + * ``` + * + * The nice thing here is that we can save bandwidth by sticking to our CSS-based animation code and we don't need to rely on a 3rd-party animation framework. + * + * The `$animateCss` service is very powerful since we can feed in all kinds of extra properties that will be evaluated and fed into a CSS transition or + * keyframe animation. For example if we wanted to animate the height of an element while adding and removing classes then we can do so by providing that + * data into `$animateCss` directly: + * + * ```js + * myModule.animation('.slide', ['$animateCss', function($animateCss) { + * return { + * enter: function(element) { + * return $animateCss(element, { + * event: 'enter', + * structural: true, + * addClass: 'maroon-setting', + * from: { height:0 }, + * to: { height: 200 } + * }); + * } + * } + * }]); + * ``` + * + * Now we can fill in the rest via our transition CSS code: + * + * ```css + * /* the transition tells ngAnimate to make the animation happen */ + * .slide.ng-enter { transition:0.5s linear all; } + * + * /* this extra CSS class will be absorbed into the transition + * since the $animateCss code is adding the class */ + * .maroon-setting { background:red; } + * ``` + * + * And `$animateCss` will figure out the rest. Just make sure to have the `done()` callback fire the `doneFn` function to signal when the animation is over. + * + * To learn more about what's possible be sure to visit the {@link ngAnimate.$animateCss $animateCss service}. + * + * ## Animation Anchoring (via `ng-animate-ref`) + * + * ngAnimate in AngularJS 1.4 comes packed with the ability to cross-animate elements between + * structural areas of an application (like views) by pairing up elements using an attribute + * called `ng-animate-ref`. + * + * Let's say for example we have two views that are managed by `ng-view` and we want to show + * that there is a relationship between two components situated in within these views. By using the + * `ng-animate-ref` attribute we can identify that the two components are paired together and we + * can then attach an animation, which is triggered when the view changes. + * + * Say for example we have the following template code: + * + * ```html + * + *
*
* - * @param {Array} attrs - A list of valid attributes. + * + * + * + * + * + * + * + * ``` + * + * Now, when the view changes (once the link is clicked), ngAnimate will examine the + * HTML contents to see if there is a match reference between any components in the view + * that is leaving and the view that is entering. It will scan both the view which is being + * removed (leave) and inserted (enter) to see if there are any paired DOM elements that + * contain a matching ref value. + * + * The two images match since they share the same ref value. ngAnimate will now create a + * transport element (which is a clone of the first image element) and it will then attempt + * to animate to the position of the second image element in the next view. For the animation to + * work a special CSS class called `ng-anchor` will be added to the transported element. + * + * We can now attach a transition onto the `.banner.ng-anchor` CSS class and then + * ngAnimate will handle the entire transition for us as well as the addition and removal of + * any changes of CSS classes between the elements: + * + * ```css + * .banner.ng-anchor { + * /* this animation will last for 1 second since there are + * two phases to the animation (an `in` and an `out` phase) */ + * transition:0.5s linear all; + * } + * ``` + * + * We also **must** include animations for the views that are being entered and removed + * (otherwise anchoring wouldn't be possible since the new view would be inserted right away). + * + * ```css + * .view-animation.ng-enter, .view-animation.ng-leave { + * transition:0.5s linear all; + * position:fixed; + * left:0; + * top:0; + * width:100%; + * } + * .view-animation.ng-enter { + * transform:translateX(100%); + * } + * .view-animation.ng-leave, + * .view-animation.ng-enter.ng-enter-active { + * transform:translateX(0%); + * } + * .view-animation.ng-leave.ng-leave-active { + * transform:translateX(-100%); + * } + * ``` + * + * Now we can jump back to the anchor animation. When the animation happens, there are two stages that occur: + * an `out` and an `in` stage. The `out` stage happens first and that is when the element is animated away + * from its origin. Once that animation is over then the `in` stage occurs which animates the + * element to its destination. The reason why there are two animations is to give enough time + * for the enter animation on the new element to be ready. + * + * The example above sets up a transition for both the in and out phases, but we can also target the out or + * in phases directly via `ng-anchor-out` and `ng-anchor-in`. + * + * ```css + * .banner.ng-anchor-out { + * transition: 0.5s linear all; + * + * /* the scale will be applied during the out animation, + * but will be animated away when the in animation runs */ + * transform: scale(1.2); + * } + * + * .banner.ng-anchor-in { + * transition: 1s linear all; + * } + * ``` + * + * + * + * + * ### Anchoring Demo + * + + + Home +

The cloned element will be placed inside of the root element + * of the application (where ng-app was defined) and all of the CSS classes of the starting element will be applied. The + * element will then animate into the `out` and `in` animations and will eventually reach the coordinates and match + * the dimensions of the destination element. During the entire animation a CSS class of `.ng-animate-shim` will be applied + * to both the starting and destination elements in order to hide them from being visible (the CSS styling for the class + * is: `visibility:hidden`). Once the anchor reaches its destination then it will be removed and the destination element + * will become visible since the shim class will be removed. + * + * ### How is the morphing handled? + * + * CSS Anchoring relies on transitions and keyframes and the internal code is intelligent enough to figure out + * what CSS classes differ between the starting element and the destination element. These different CSS classes + * will be added/removed on the anchor element and a transition will be applied (the transition that is provided + * in the anchor class). Long story short, ngAnimate will figure out what classes to add and remove which will + * make the transition of the element as smooth and automatic as possible. Be sure to use simple CSS classes that + * do not rely on DOM nesting structure so that the anchor element appears the same as the starting element (since + * the cloned element is placed inside of root element which is likely close to the body element). + * + * Note that if the root element is on the `` element then the cloned node will be placed inside of body. + * + * + * ## Using $animate in your directive code + * + * So far we've explored how to feed in animations into an AngularJS application, but how do we trigger animations within our own directives in our application? + * By injecting the `$animate` service into our directive code, we can trigger structural and class-based hooks which can then be consumed by animations. Let's + * imagine we have a greeting box that shows and hides itself when the data changes + * + * ```html + * Hi there + * ``` + * + * ```js + * ngModule.directive('greetingBox', ['$animate', function($animate) { + * return function(scope, element, attrs) { + * attrs.$observe('active', function(value) { + * value ? $animate.addClass(element, 'on') : $animate.removeClass(element, 'on'); + * }); + * }); + * }]); + * ``` + * + * Now the `on` CSS class is added and removed on the greeting box component. Now if we add a CSS class on top of the greeting box element + * in our HTML code then we can trigger a CSS or JS animation to happen. + * + * ```css + * /* normally we would create a CSS class to reference on the element */ + * greeting-box.on { transition:0.5s linear all; background:green; color:white; } + * ``` + * + * The `$animate` service contains a variety of other methods like `enter`, `leave`, `animate` and `setClass`. To learn more about what's + * possible be sure to visit the {@link ng.$animate $animate service API page}. + * + * + * ## Callbacks and Promises + * + * When `$animate` is called it returns a promise that can be used to capture when the animation has ended. Therefore if we were to trigger + * an animation (within our directive code) then we can continue performing directive and scope related activities after the animation has + * ended by chaining onto the returned promise that animation method returns. + * + * ```js + * // somewhere within the depths of the directive + * $animate.enter(element, parent).then(function() { + * //the animation has completed + * }); + * ``` + * + * (Note that earlier versions of AngularJS prior to v1.4 required the promise code to be wrapped using `$scope.$apply(...)`. This is not the case + * anymore.) + * + * In addition to the animation promise, we can also make use of animation-related callbacks within our directives and controller code by registering + * an event listener using the `$animate` service. Let's say for example that an animation was triggered on our view + * routing controller to hook into that: + * + * ```js + * ngModule.controller('HomePageController', ['$animate', function($animate) { + * $animate.on('enter', ngViewElement, function(element) { + * // the animation for this route has completed + * }]); + * }]) + * ``` * - * @returns {$sanitizeProvider} Returns self for chaining. + * (Note that you will need to trigger a digest within the callback to get AngularJS to notice any scope-related changes.) */ - this.addValidAttrs = function(attrs) { - if (!hasBeenInstantiated) { - extend(validAttrs, arrayToMap(attrs, true));

- * This object provides a utility for producing rich Error messages within

- * var exampleMinErr = minErr('example');
- * throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
- *
- * The above creates an instance of minErr in the example namespace. The
- * resulting error will have a namespaced error code of example.one.  The
- * resulting error will replace {0} with the value of foo, and {1} with the
- * value of bar. The object is not restricted in the number of arguments it can
- * take.
- *
- * If fewer arguments are specified than necessary for interpolation, the extra
- * interpolation markers will be preserved in the final string.
- *
- * Since data will be parsed statically during a build step, some restrictions
- * are applied with respect to how minErr instances are created and called.
- * Instances should have names of the form namespaceMinErr for a minErr created
- * using minErr('namespace') . Error codes, namespaces and template strings
- * should all be static strings, not variables or general expressions.

- * @name angular.copy
- * @module ng
- * @kind function
- *
- * @description
- * Creates a deep copy of `source`, which should be an object or an array.
- *
- * * If no destination is supplied, a copy of the object or array is created.
- * * If a destination is provided, all of its elements (for arrays) or properties (for objects)
- *   are deleted and then all elements/properties from the source are copied to it.
- * * If `source` is not an object or array (inc. `null` and `undefined`), `source` is returned.
- * * If `source` is identical to `destination` an exception will be thrown.
- *
- * 

- * 

- *   Only enumerable properties are taken into account. Non-enumerable properties (both on `source`
- *   and on `destination`) will be ignored.
- * 

- *
- * @param {*} source The source that will be used to make a copy.
- *                   Can be any type, including primitives, `null`, and `undefined`.
- * @param {(Object|Array)=} destination Destination into which the source is copied. If
- *     provided, must be of the same type as `source`.
- * @returns {*} The copy or updated `destination`, if `destination` was specified.

- * @ngdoc directive
- * @name ngApp
- * @module ng
- *
- * @element ANY
- * @param {angular.Module} ngApp an optional application
- *   {@link angular.module module} name to load.
- * @param {boolean=} ngStrictDi if this attribute is present on the app element, the injector will be
- *   created in "strict-di" mode. This means that the application will fail to invoke functions which
- *   do not use explicit function annotation (and are thus unsuitable for minification), as described
- *   in {@link guide/di the Dependency Injection guide}, and useful debugging info will assist in
- *   tracking down the root of these bugs.
- *
- * @description
- *
- * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
- * designates the **root element** of the application and is typically placed near the root element
- * of the page - e.g. on the `` or `` tags.
- *
- * There are a few things to keep in mind when using `ngApp`:
- * - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
- *   found in the document will be used to define the root element to auto-bootstrap as an
- *   application. To run multiple applications in an HTML document you must manually bootstrap them using
- *   {@link angular.bootstrap} instead.
- * - AngularJS applications cannot be nested within each other.
- * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.
- *   This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and
- *   {@link ngRoute.ngView `ngView`}.
- *   Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
- *   causing animations to stop working and making the injector inaccessible from outside the app.
- *
- * You can specify an **AngularJS module** to be used as the root module for the application.  This
- * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
- * should contain the application code needed or have dependencies on other modules that will
- * contain the code. See {@link angular.module} for more information.
- *
- * In the example below if the `ngApp` directive were not placed on the `html` element then the
- * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
- * would not be resolved to `3`.
- *
- * @example
- *
- * ### Simple Usage
- *
- * `ngApp` is the easiest, and most common way to bootstrap an application.
- *
- 
-   
-   

-     I can add: {{a}} + {{b}} =  {{ a+b }}
-   

-   
-   
-   angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) {
-     $scope.a = 1;
-     $scope.b = 2;
-   });
-   
- 
- *
- * @example
- *
- * ### With `ngStrictDi`
- *
- * Using `ngStrictDi`, you would see something like this:
- *
- 
-   
-   

-       

-           I can add: {{a}} + {{b}} =  {{ a+b }}
-
-           
This renders because the controller does not fail to
-              instantiate, by using explicit annotation style (see
-              script.js for details)
-           

-       

-
-       

-           Name: 

-           Hello, {{name}}!
+    return jq.name_ = name;
+  };
 
-           
This renders because the controller does not fail to
-              instantiate, by using explicit annotation style
-              (see script.js for details)
-           

-       

+  function concat(array1, array2, index) {
+    return array1.concat(slice.call(array2, index));
+  }
 
-       

-           I can add: {{a}} + {{b}} =  {{ a+b }}
+  function sliceArgs(args, startIndex) {
+    return slice.call(args, startIndex || 0);
+  }
 
-           
The controller could not be instantiated, due to relying
-              on automatic function annotations (which are disabled in
-              strict mode). As such, the content of this section is not
-              interpolated, and there should be an error in your web console.

-   
-   
-   angular.module('ngAppStrictDemo', [])
-     // BadController will fail to instantiate, due to relying on automatic function annotation,
-     // rather than an explicit annotation
-     .controller('BadController', function($scope) {
-       $scope.a = 1;
-       $scope.b = 2;
-     })
-     // Unlike BadController, GoodController1 and GoodController2 will not fail to be instantiated,
-     // due to using explicit annotations using the array style and $inject property, respectively.

+  /**
+   * @ngdoc directive
+   * @name ngApp
+   * @module ng
+   *
+   * @element ANY
+   * @param {angular.Module} ngApp an optional application
+   *   {@link angular.module module} name to load.
+   * @param {boolean=} ngStrictDi if this attribute is present on the app element, the injector will be
+   *   created in "strict-di" mode. This means that the application will fail to invoke functions which
+   *   do not use explicit function annotation (and are thus unsuitable for minification), as described
+   *   in {@link guide/di the Dependency Injection guide}, and useful debugging info will assist in
+   *   tracking down the root of these bugs.
+   *
+   * @description
+   *
+   * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
+   * designates the **root element** of the application and is typically placed near the root element
+   * of the page - e.g. on the `` or `` tags.
+   *
+   * There are a few things to keep in mind when using `ngApp`:
+   * - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
+   *   found in the document will be used to define the root element to auto-bootstrap as an
+   *   application. To run multiple applications in an HTML document you must manually bootstrap them using
+   *   {@link angular.bootstrap} instead.
+   * - AngularJS applications cannot be nested within each other.
+   * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.
+   *   This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and
+   *   {@link ngRoute.ngView `ngView`}.
+   *   Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
+   *   causing animations to stop working and making the injector inaccessible from outside the app.
+   *
+   * You can specify an **AngularJS module** to be used as the root module for the application.  This
+   * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
+   * should contain the application code needed or have dependencies on other modules that will
+   * contain the code. See {@link angular.module} for more information.
+   *
+   * In the example below if the `ngApp` directive were not placed on the `html` element then the
+   * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
+   * would not be resolved to `3`.
+   *
+   * @example
+   *
+   * ### Simple Usage
+   *
+   * `ngApp` is the easiest, and most common way to bootstrap an application.
+   *
+   
+     
+     

+       I can add: {{a}} + {{b}} =  {{ a+b }}
+     

+     
+     
+     angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) {
+       $scope.a = 1;
+       $scope.b = 2;
+     });
+     
+   
+   *
+   * @example
+   *
+   * ### With `ngStrictDi`
+   *
+   * Using `ngStrictDi`, you would see something like this:
+   *
+   
+     
+     

+         

+             I can add: {{a}} + {{b}} =  {{ a+b }}
+  
+             
This renders because the controller does not fail to
+                instantiate, by using explicit annotation style (see
+                script.js for details)
+             

+         

+  
+         

+             Name: 

+             Hello, {{name}}!
+  
+             
This renders because the controller does not fail to
+                instantiate, by using explicit annotation style
+                (see script.js for details)
+             

+         

+  
+         

+             I can add: {{a}} + {{b}} =  {{ a+b }}
+  
+             
The controller could not be instantiated, due to relying
+                on automatic function annotations (which are disabled in
+                strict mode). As such, the content of this section is not
+                interpolated, and there should be an error in your web console.

+

+       * @module ng
+       * @description
+       *
+       * The `angular.module` is a global place for creating, registering and retrieving AngularJS
+       * modules.
+       * All modules (AngularJS core or 3rd party) that should be available to an application must be
+       * registered using this mechanism.
+       *
+       * Passing one argument retrieves an existing {@link angular.Module},
+       * whereas passing more than one argument creates a new {@link angular.Module}
+       *
+       *
+       * # Module
+       *
+       * A module is a collection of services, directives, controllers, filters, and configuration information.
+       * `angular.module` is used to configure the {@link auto.$injector $injector}.
+       *
+       * ```js
+       * // Create a new module
+       * var myModule = angular.module('myModule', []);
+       *
+       * // register a new service
+       * myModule.value('appName', 'MyCoolApp');
+       *
+       * // configure existing services inside initialization blocks.
+       * myModule.config(['$locationProvider', function($locationProvider) {
+       *   // Configure existing providers
+       *   $locationProvider.hashPrefix('!');
+       * }]);
+       * ```
+       *
+       * Then you can create an injector and load your modules like this:
+       *
+       * ```js
+       * var injector = angular.injector(['ng', 'myModule'])
+       * ```
+       *
+       * However it's more likely that you'll just use
+       * {@link ng.directive:ngApp ngApp} or
+       * {@link angular.bootstrap} to simplify this process for you.
+       *
+       * @param {!string} name The name of the module to create or retrieve.
+       * @param {!Array.=} requires If specified then new module is being created. If
+       *        unspecified then the module is being retrieved for further configuration.
+       * @param {Function=} configFn Optional configuration function for the module. Same as
+       *        {@link angular.Module#config Module#config()}.
+       * @returns {angular.Module} new module with the {@link angular.Module} api.

-/**
- * @ngdoc function
- * @name angular.element
- * @module ng
- * @kind function
- *
- * @description
- * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
- *
- * If jQuery is available, `angular.element` is an alias for the
- * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
- * delegates to AngularJS's built-in subset of jQuery, called "jQuery lite" or **jqLite**.
- *
- * jqLite is a tiny, API-compatible subset of jQuery that allows
- * AngularJS to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most
- * commonly needed functionality with the goal of having a very small footprint.
- *
- * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the
- * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a
- * specific version of jQuery if multiple versions exist on the page.
- *
- * 
**Note:** All element references in AngularJS are always wrapped with jQuery or
- * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.

- *
- * 
**Note:** Keep in mind that this function will not find elements
- * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`
- * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.

- *
- * ## AngularJS's jqLite
- * jqLite provides only the following jQuery methods:
- *
- * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument
- * - [`after()`](http://api.jquery.com/after/)
- * - [`append()`](http://api.jquery.com/append/) - Contrary to jQuery, this doesn't clone elements
- *   so will not work correctly when invoked on a jqLite object containing more than one DOM node
- * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
- * - [`bind()`](http://api.jquery.com/bind/) (_deprecated_, use [`on()`](http://api.jquery.com/on/)) - Does not support namespaces, selectors or eventData
- * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
- * - [`clone()`](http://api.jquery.com/clone/)
- * - [`contents()`](http://api.jquery.com/contents/)
- * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.
- *   As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.
- * - [`data()`](http://api.jquery.com/data/)
- * - [`detach()`](http://api.jquery.com/detach/)
- * - [`empty()`](http://api.jquery.com/empty/)
- * - [`eq()`](http://api.jquery.com/eq/)
- * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
- * - [`hasClass()`](http://api.jquery.com/hasClass/)
- * - [`html()`](http://api.jquery.com/html/)
- * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
- * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
- * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter
- * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
- * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
- * - [`prepend()`](http://api.jquery.com/prepend/)
- * - [`prop()`](http://api.jquery.com/prop/)
- * - [`ready()`](http://api.jquery.com/ready/) (_deprecated_, use `angular.element(callback)` instead of `angular.element(document).ready(callback)`)
- * - [`remove()`](http://api.jquery.com/remove/)
- * - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes
- * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument
- * - [`removeData()`](http://api.jquery.com/removeData/)
- * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
- * - [`text()`](http://api.jquery.com/text/)
- * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument
- * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers
- * - [`unbind()`](http://api.jquery.com/unbind/) (_deprecated_, use [`off()`](http://api.jquery.com/off/)) - Does not support namespaces or event object as parameter
- * - [`val()`](http://api.jquery.com/val/)
- * - [`wrap()`](http://api.jquery.com/wrap/)
- *
- * ## jQuery/jqLite Extras
- * AngularJS also provides the following additional methods and events to both jQuery and jqLite:
- *
- * ### Events
- * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
- *    on all DOM nodes being removed.  This can be used to clean up any 3rd party bindings to the DOM
- *    element before it is removed.
- *
- * ### Methods
- * - `controller(name)` - retrieves the controller of the current element or its parent. By default
- *   retrieves controller associated with the `ngController` directive. If `name` is provided as
- *   camelCase directive name, then the controller for this directive will be retrieved (e.g.
- *   `'ngModel'`).

+   * @ngdoc function
+   * @name angular.element
+   * @module ng
+   * @kind function
+   *
+   * @description
+   * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
+   *
+   * If jQuery is available, `angular.element` is an alias for the
+   * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
+   * delegates to AngularJS's built-in subset of jQuery, called "jQuery lite" or **jqLite**.
+   *
+   * jqLite is a tiny, API-compatible subset of jQuery that allows
+   * AngularJS to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most
+   * commonly needed functionality with the goal of having a very small footprint.
+   *
+   * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the
+   * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a
+   * specific version of jQuery if multiple versions exist on the page.
+   *
+   * 
**Note:** All element references in AngularJS are always wrapped with jQuery or
+   * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.

+   *
+   * 
**Note:** Keep in mind that this function will not find elements
+   * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`
+   * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.

+   *
+   * ## AngularJS's jqLite
+   * jqLite provides only the following jQuery methods:
+   *
+   * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument
+   * - [`after()`](http://api.jquery.com/after/)
+   * - [`append()`](http://api.jquery.com/append/) - Contrary to jQuery, this doesn't clone elements
+   *   so will not work correctly when invoked on a jqLite object containing more than one DOM node
+   * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
+   * - [`bind()`](http://api.jquery.com/bind/) (_deprecated_, use [`on()`](http://api.jquery.com/on/)) - Does not support namespaces, selectors or eventData
+   * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
+   * - [`clone()`](http://api.jquery.com/clone/)
+   * - [`contents()`](http://api.jquery.com/contents/)
+   * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.
+   *   As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.
+   * - [`data()`](http://api.jquery.com/data/)
+   * - [`detach()`](http://api.jquery.com/detach/)
+   * - [`empty()`](http://api.jquery.com/empty/)
+   * - [`eq()`](http://api.jquery.com/eq/)
+   * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
+   * - [`hasClass()`](http://api.jquery.com/hasClass/)
+   * - [`html()`](http://api.jquery.com/html/)
+   * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
+   * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
+   * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter
+   * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
+   * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
+   * - [`prepend()`](http://api.jquery.com/prepend/)
+   * - [`prop()`](http://api.jquery.com/prop/)
+   * - [`ready()`](http://api.jquery.com/ready/) (_deprecated_, use `angular.element(callback)` instead of `angular.element(document).ready(callback)`)
+   * - [`remove()`](http://api.jquery.com/remove/)
+   * - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes
+   * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument
+   * - [`removeData()`](http://api.jquery.com/removeData/)
+   * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
+   * - [`text()`](http://api.jquery.com/text/)
+   * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument
+   * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers
+   * - [`unbind()`](http://api.jquery.com/unbind/) (_deprecated_, use [`off()`](http://api.jquery.com/off/)) - Does not support namespaces or event object as parameter
+   * - [`val()`](http://api.jquery.com/val/)
+   * - [`wrap()`](http://api.jquery.com/wrap/)
+   *
+   * ## jQuery/jqLite Extras
+   * AngularJS also provides the following additional methods and events to both jQuery and jqLite:
+   *
+   * ### Events
+   * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
+   *    on all DOM nodes being removed.  This can be used to clean up any 3rd party bindings to the DOM
+   *    element before it is removed.
+   *
+   * ### Methods
+   * - `controller(name)` - retrieves the controller of the current element or its parent. By default
+   *   retrieves controller associated with the `ngController` directive. If `name` is provided as
+   *   camelCase directive name, then the controller for this directive will be retrieved (e.g.
+   *   `'ngModel'`).
+   * - `injector()` - retrieves the injector of the current element or its parent.
+   * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
+   *   element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to
+   *   be enabled.
+   * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
+   *   current element. This getter should be used only on elements that contain a directive which starts a new isolate
+   *   scope. Calling `scope()` on this element always returns the original non-isolate scope.
+   *   Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.
+   * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
+   *   parent element is reached.
+   *
+   * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See
+   * https://github.com/angular/angular.js/issues/14251 for more information.
+   *
+   * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
+   * @returns {Object} jQuery object.

- * @description
- * Creates an injector object that can be used for retrieving services as well as for
- * dependency injection (see {@link guide/di dependency injection}).
- *
- * @param {Array.} modules A list of module functions or their aliases. See
- *     {@link angular.module}. The `ng` module must be explicitly added.
- * @param {boolean=} [strictDi=false] Whether the injector should be in strict mode, which
- *     disallows argument name annotation inference.
- * @returns {injector} Injector object. See {@link auto.$injector $injector}.
- *
- * @example
- * Typical usage
- * ```js
- *   // create an injector
- *   var $injector = angular.injector(['ng']);
- *
- *   // use the injector to kick off your application
- *   // use the type inference to auto inject arguments, or use implicit injection
- *   $injector.invoke(function($rootScope, $compile, $document) {
- *     $compile($document)($rootScope);
- *     $rootScope.$digest();
- *   });
- * ```
- *
- * Sometimes you want to get access to the injector of a currently running AngularJS app
- * from outside AngularJS. Perhaps, you want to inject and compile some markup after the
- * application has been bootstrapped. You can do this using the extra `injector()` added
- * to JQuery/jqLite elements. See {@link angular.element}.
- *
- * *This is fairly rare but could be the case if a third party library is injecting the
- * markup.*
- *
- * In the following example a new block of HTML containing a `ng-controller`
- * directive is added to the end of the document body by JQuery. We then compile and link
- * it into the current AngularJS scope.
- *
- * ```js
- * var $div = $('
{{content.label}}
');
- * $(document.body).append($div);
- *
- * angular.element(document).injector().invoke(function($compile) {

-/**
- * @ngdoc service
- * @name $injector
- *
- * @description
- *
- * `$injector` is used to retrieve object instances as defined by
- * {@link auto.$provide provider}, instantiate types, invoke methods,
- * and load modules.
- *
- * The following always holds true:
- *
- * ```js
- *   var $injector = angular.injector();
- *   expect($injector.get('$injector')).toBe($injector);
- *   expect($injector.invoke(function($injector) {
- *     return $injector;
- *   })).toBe($injector);
- * ```
- *
- * ## Injection Function Annotation
- *
- * JavaScript does not have annotations, and annotations are needed for dependency injection. The
- * following are all valid ways of annotating function with injection arguments and are equivalent.
- *
- * ```js
- *   // inferred (only works if code not minified/obfuscated)
- *   $injector.invoke(function(serviceA){});
- *
- *   // annotated
- *   function explicit(serviceA) {};
- *   explicit.$inject = ['serviceA'];
- *   $injector.invoke(explicit);
- *
- *   // inline
- *   $injector.invoke(['serviceA', function(serviceA){}]);
- * ```
- *
- * ### Inference
- *
- * In JavaScript calling `toString()` on a function returns the function definition. The definition
- * can then be parsed and the function arguments can be extracted. This method of discovering
- * annotations is disallowed when the injector is in strict mode.
- * *NOTE:* This does not work with minification, and obfuscation tools since these tools change the
- * argument names.
- *
- * ### `$inject` Annotation
- * By adding an `$inject` property onto a function the injection parameters can be specified.
- *
- * ### Inline
- * As an array of injection names, where the last item in the array is the function to call.

-/**
- * @ngdoc method
- * @name $injector#annotate
- *
- * @description
- * Returns an array of service names which the function is requesting for injection. This API is
- * used by the injector to determine which services need to be injected into the function when the
- * function is invoked. There are three ways in which the function can be annotated with the needed
- * dependencies.
- *
- * #### Argument names
- *
- * The simplest form is to extract the dependencies from the arguments of the function. This is done
- * by converting the function into a string using `toString()` method and extracting the argument
- * names.
- * ```js
- *   // Given
- *   function MyController($scope, $route) {
- *     // ...
- *   }
- *
- *   // Then
- *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
- * ```
- *
- * You can disallow this method by using strict injection mode.
- *
- * This method does not work with code minification / obfuscation. For this reason the following
- * annotation strategies are supported.
- *
- * #### The `$inject` property
- *
- * If a function has an `$inject` property and its value is an array of strings, then the strings
- * represent names of services to be injected into the function.
- * ```js
- *   // Given
- *   var MyController = function(obfuscatedScope, obfuscatedRoute) {
- *     // ...
- *   }
- *   // Define function dependencies
- *   MyController['$inject'] = ['$scope', '$route'];
- *
- *   // Then
- *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
- * ```
- *
- * #### The array notation
- *
- * It is often desirable to inline Injected functions and that's when setting the `$inject` property
- * is very inconvenient. In these situations using the array notation to specify the dependencies in
- * a way that survives minification is a better choice:
- *
- * ```js
- *   // We wish to write this (not minification / obfuscation safe)
- *   injector.invoke(function($compile, $rootScope) {
- *     // ...
- *   });
- *
- *   // We are forced to write break inlining
- *   var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
- *     // ...
- *   };
- *   tmpFn.$inject = ['$compile', '$rootScope'];
- *   injector.invoke(tmpFn);
- *
- *   // To better support inline function the inline annotation is supported
- *   injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
- *     // ...
- *   }]);
- *
- *   // Therefore
- *   expect(injector.annotate(
- *      ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
- *    ).toEqual(['$compile', '$rootScope']);
- * ```
- *
- * @param {Function|Array.} fn Function for which dependent service names need to
- * be retrieved as described above.
- *
- * @param {boolean=} [strictDi=false] Disallow argument name annotation inference.
- *
- * @returns {Array.} The names of the services which the function requires.

- *

- *
- * Add the specified modules to the current injector.
- *
- * This method will add each of the injectables to the injector and execute all of the config and run

- * * Modules cannot be unloaded.
- *
- * You can use {@link $injector#modules `$injector.modules`} to check whether a module has been loaded

- * @description
- *
- * The {@link auto.$provide $provide} service has a number of methods for registering components
- * with the {@link auto.$injector $injector}. Many of these functions are also exposed on
- * {@link angular.Module}.
- *
- * An AngularJS **service** is a singleton object created by a **service factory**.  These **service
- * factories** are functions which, in turn, are created by a **service provider**.
- * The **service providers** are constructor functions. When instantiated they must contain a
- * property called `$get`, which holds the **service factory** function.
- *
- * When you request a service, the {@link auto.$injector $injector} is responsible for finding the
- * correct **service provider**, instantiating it and then calling its `$get` **service factory**
- * function to get the instance of the **service**.
- *
- * Often services have no configuration options and there is no need to add methods to the service
- * provider.  The provider will be no more than a constructor function with a `$get` property. For
- * these cases the {@link auto.$provide $provide} service has additional helper methods to register
- * services without specifying a provider.

-/**
- * @ngdoc method
- * @name $provide#provider
- * @description
- *
- * Register a **provider function** with the {@link auto.$injector $injector}. Provider functions
- * are constructor functions, whose instances are responsible for "providing" a factory for a
- * service.
- *
- * Service provider names start with the name of the service they provide followed by `Provider`.
- * For example, the {@link ng.$log $log} service has a provider called
- * {@link ng.$logProvider $logProvider}.
- *
- * Service provider objects can have additional methods which allow configuration of the provider
- * and its service. Importantly, you can configure what kind of service is created by the `$get`
- * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
- * method {@link ng.$logProvider#debugEnabled debugEnabled}
- * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
- * console or not.
- *
- * It is possible to inject other providers into the provider function,
- * but the injected provider must have been defined before the one that requires it.
- *
- * @param {string} name The name of the instance. NOTE: the provider will be available under `name +
-                        'Provider'` key.
- * @param {(Object|function())} provider If the provider is:
- *
- *   - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
- *     {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
- *   - `Constructor`: a new instance of the provider will be created using
- *     {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.
- *
- * @returns {Object} registered provider instance
-
- * @example
- *
- * The following example shows how to create a simple event tracking service and register it using
- * {@link auto.$provide#provider $provide.provider()}.
- *
- * ```js
- *  // Define the eventTracker provider
- *  function EventTrackerProvider() {
- *    var trackingUrl = '/track';
- *
- *    // A provider method for configuring where the tracked events should been saved
- *    this.setTrackingUrl = function(url) {
- *      trackingUrl = url;
- *    };
- *
- *    // The service factory function
- *    this.$get = ['$http', function($http) {
- *      var trackedEvents = {};
- *      return {
- *        // Call this to track an event
- *        event: function(event) {
- *          var count = trackedEvents[event] || 0;
- *          count += 1;
- *          trackedEvents[event] = count;
- *          return count;
- *        },
- *        // Call this to save the tracked events to the trackingUrl
- *        save: function() {
- *          $http.post(trackingUrl, trackedEvents);
- *        }
- *      };
- *    }];
- *  }
- *
- *  describe('eventTracker', function() {
- *    var postSpy;
- *
- *    beforeEach(module(function($provide) {
- *      // Register the eventTracker provider
- *      $provide.provider('eventTracker', EventTrackerProvider);
- *    }));
- *
- *    beforeEach(module(function(eventTrackerProvider) {
- *      // Configure eventTracker provider
- *      eventTrackerProvider.setTrackingUrl('/custom-track');
- *    }));
- *
- *    it('tracks events', inject(function(eventTracker) {
- *      expect(eventTracker.event('login')).toEqual(1);
- *      expect(eventTracker.event('login')).toEqual(2);
- *    }));
- *
- *    it('saves to the tracking url', inject(function(eventTracker, $http) {
- *      postSpy = spyOn($http, 'post');
- *      eventTracker.event('login');
- *      eventTracker.save();
- *      expect(postSpy).toHaveBeenCalled();
- *      expect(postSpy.mostRecentCall.args[0]).not.toEqual('/track');
- *      expect(postSpy.mostRecentCall.args[0]).toEqual('/custom-track');
- *      expect(postSpy.mostRecentCall.args[1]).toEqual({ 'login': 1 });
- *    }));

-/**
- * @ngdoc method
- * @name $provide#factory
- * @description
- *
- * Register a **service factory**, which will be called to return the service instance.
- * This is short for registering a service where its provider consists of only a `$get` property,
- * which is the given service factory function.
- * You should use {@link auto.$provide#factory $provide.factory(getFn)} if you do not need to
- * configure your service in a provider.
- *
- * @param {string} name The name of the instance.
- * @param {Function|Array.} $getFn The injectable $getFn for the instance creation.
- *                      Internally this is a short hand for `$provide.provider(name, {$get: $getFn})`.
- * @returns {Object} registered provider instance
- *
- * @example
- * Here is an example of registering a service
- * ```js

- *     return function ping() {
- *       return $http.send('/ping');
- *     };

- * This is short for registering a service where its provider's `$get` property is a factory
- * function that returns an instance instantiated by the injector from the service constructor

- *
- * ```
- * {
- *   $get: function() {
- *     return $injector.instantiate(constructor);
- *   }
- * }
- * ```
- *
- *
- * You should use {@link auto.$provide#service $provide.service(class)} if you define your service
- * as a type/class.
- *
- * @param {string} name The name of the instance.
- * @param {Function|Array.} constructor An injectable class (constructor function)
- *     that will be instantiated.
- * @returns {Object} registered provider instance
- *
- * @example
- * Here is an example of registering a service using

-/**
- * @ngdoc method
- * @name $provide#value
- * @description
- *
- * Register a **value service** with the {@link auto.$injector $injector}, such as a string, a
- * number, an array, an object or a function. This is short for registering a service where its
- * provider's `$get` property is a factory function that takes no arguments and returns the **value
- * service**. That also means it is not possible to inject other services into a value service.
- *
- * Value services are similar to constant services, except that they cannot be injected into a
- * module configuration function (see {@link angular.Module#config}) but they can be overridden by
- * an AngularJS {@link auto.$provide#decorator decorator}.
- *
- * @param {string} name The name of the instance.
- * @param {*} value The value.
- * @returns {Object} registered provider instance
- *

- * @ngdoc method

- * @description
- *
- * Register a **decorator function** with the {@link auto.$injector $injector}. A decorator function
- * intercepts the creation of a service, allowing it to override or modify the behavior of the
- * service. The return value of the decorator function may be the original service, or a new service
- * that replaces (or wraps and delegates to) the original service.
- *
- * You can find out more about using decorators in the {@link guide/decorators} guide.
- *
- * @param {string} name The name of the service to decorate.
- * @param {Function|Array.} decorator This function will be invoked when the service needs to be
- *    provided and should return the decorated service instance. The function is called using
- *    the {@link auto.$injector#invoke injector.invoke} method and is therefore fully injectable.
- *    Local injection arguments:
- *
- *    * `$delegate` - The original service instance, which can be replaced, monkey patched, configured,
- *      decorated or delegated to.
- *
- * @example
- * Here we decorate the {@link ng.$log $log} service to convert warnings to errors by intercepting
- * calls to {@link ng.$log#error $log.warn()}.
- * ```js
- *   $provide.decorator('$log', ['$delegate', function($delegate) {

-   * @name $anchorScroll
+   * @ngdoc function

-   * @requires $rootScope
    *
    * @description
-   * When called, it scrolls to the element related to the specified `hash` or (if omitted) to the
-   * current value of {@link ng.$location#hash $location.hash()}, according to the rules specified
-   * in the
-   * [HTML5 spec](http://www.w3.org/html/wg/drafts/html/master/browsers.html#an-indicated-part-of-the-document).
-   *
-   * It also watches the {@link ng.$location#hash $location.hash()} and automatically scrolls to
-   * match any anchor whenever it changes. This can be disabled by calling
-   * {@link ng.$anchorScrollProvider#disableAutoScrolling $anchorScrollProvider.disableAutoScrolling()}.
-   *
-   * Additionally, you can use its {@link ng.$anchorScroll#yOffset yOffset} property to specify a
-   * vertical scroll-offset (either fixed or dynamic).
-   *
-   * @param {string=} hash The hash specifying the element to scroll to. If omitted, the value of
-   *                       {@link ng.$location#hash $location.hash()} will be used.
-   *
-   * @property {(number|function|jqLite)} yOffset
-   * If set, specifies a vertical scroll-offset. This is often useful when there are fixed
-   * positioned elements at the top of the page, such as navbars, headers etc.
-   *
-   * `yOffset` can be specified in various ways:
-   * - **number**: A fixed number of pixels to be used as offset.


-   * - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return
-   *   a number representing the offset (in pixels).


-   * - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from
-   *   the top of the page to the element's bottom will be used as offset.

-   *   **Note**: The element will be taken into account only as long as its `position` is set to
-   *   `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust
-   *   their height and/or positioning according to the viewport's size.
+   * Creates an injector object that can be used for retrieving services as well as for
+   * dependency injection (see {@link guide/di dependency injection}).
    *
-   * 

-   * 

-   * In order for `yOffset` to work properly, scrolling should take place on the document's root and
-   * not some child element.
-   * 

+   * @param {Array.} modules A list of module functions or their aliases. See
+   *     {@link angular.module}. The `ng` module must be explicitly added.
+   * @param {boolean=} [strictDi=false] Whether the injector should be in strict mode, which
+   *     disallows argument name annotation inference.
+   * @returns {injector} Injector object. See {@link auto.$injector $injector}.
    *
    * @example
-     
-       
-         

-           Go to bottom
-            You're at the bottom!
-         

-       
-       
-         angular.module('anchorScrollExample', [])
-           .controller('ScrollController', ['$scope', '$location', '$anchorScroll',
-             function($scope, $location, $anchorScroll) {
-               $scope.gotoBottom = function() {
-                 // set the location.hash to the id of
-                 // the element you wish to scroll to.
-                 $location.hash('bottom');
-
-                 // call $anchorScroll()
-                 $anchorScroll();
-               };
-             }]);
-       
-       
-         #scrollArea {
-           height: 280px;
-           overflow: auto;
-         }
-
-         #bottom {
-           display: block;
-           margin-top: 2000px;
-         }
-       
-     
+   * Typical usage
+   * ```js
+   *   // create an injector
+   *   var $injector = angular.injector(['ng']);
+   *
+   *   // use the injector to kick off your application
+   *   // use the type inference to auto inject arguments, or use implicit injection
+   *   $injector.invoke(function($rootScope, $compile, $document) {
+   *     $compile($document)($rootScope);
+   *     $rootScope.$digest();
+   *   });
+   * ```
    *
-   * 

-   * The example below illustrates the use of a vertical scroll-offset (specified as a fixed value).
-   * See {@link ng.$anchorScroll#yOffset $anchorScroll.yOffset} for more details.
+   * Sometimes you want to get access to the injector of a currently running AngularJS app
+   * from outside AngularJS. Perhaps, you want to inject and compile some markup after the
+   * application has been bootstrapped. You can do this using the extra `injector()` added
+   * to JQuery/jqLite elements. See {@link angular.element}.
    *
-   * @example
-     
-       
-         

-           
-             Go to anchor {{x}}

+   * *This is fairly rare but could be the case if a third party library is injecting the

-   * @name $animateProvider#register
+  /**
+   * @ngdoc service
+   * @name $injector
    *
    * @description
-   * Registers a new injectable animation factory function. The factory function produces the
-   * animation object which contains callback functions for each event that is expected to be
-   * animated.
    *
-   *   * `eventFn`: `function(element, ... , doneFunction, options)`
-   *   The element to animate, the `doneFunction` and the options fed into the animation. Depending
-   *   on the type of animation additional arguments will be injected into the animation function. The
-   *   list below explains the function signatures for the different animation methods:
+   * `$injector` is used to retrieve object instances as defined by
+   * {@link auto.$provide provider}, instantiate types, invoke methods,
+   * and load modules.
    *
-   *   - setClass: function(element, addedClasses, removedClasses, doneFunction, options)

-   *   - removeClass: function(element, removedClasses, doneFunction, options)
-   *   - enter, leave, move: function(element, doneFunction, options)
-   *   - animate: function(element, fromStyles, toStyles, doneFunction, options)
+   * The following always holds true:
    *
-   *   Make sure to trigger the `doneFunction` once the animation is fully complete.
+   * ```js
+   *   var $injector = angular.injector();
+   *   expect($injector.get('$injector')).toBe($injector);
+   *   expect($injector.invoke(function($injector) {
+   *     return $injector;
+   *   })).toBe($injector);
+   * ```
+   *
+   * ## Injection Function Annotation
+   *
+   * JavaScript does not have annotations, and annotations are needed for dependency injection. The
+   * following are all valid ways of annotating function with injection arguments and are equivalent.
    *
    * ```js
-   *   return {
-   *     //enter, leave, move signature
-   *     eventFn : function(element, done, options) {
-   *       //code to run the animation
-   *       //once complete, then run done()
-   *       return function endFunction(wasCancelled) {
-   *         //code to cancel the animation
-   *       }
-   *     }
-   *   }
+   *   // inferred (only works if code not minified/obfuscated)
+   *   $injector.invoke(function(serviceA){});
+   *
+   *   // annotated
+   *   function explicit(serviceA) {};
+   *   explicit.$inject = ['serviceA'];
+   *   $injector.invoke(explicit);

    * ```
    *
-   * @param {string} name The name of the animation (this is what the class-based CSS value will be compared to).
-   * @param {Function} factory The factory function that will be executed to return the animation
-   *                           object.
+   * ### Inference
+   *
+   * In JavaScript calling `toString()` on a function returns the function definition. The definition
+   * can then be parsed and the function arguments can be extracted. This method of discovering
+   * annotations is disallowed when the injector is in strict mode.
+   * *NOTE:* This does not work with minification, and obfuscation tools since these tools change the
+   * argument names.
+   *
+   * ### `$inject` Annotation
+   * By adding an `$inject` property onto a function the injection parameters can be specified.
+   *
+   * ### Inline
+   * As an array of injection names, where the last item in the array is the function to call.

   /**

+   * @description
+   * Returns an array of service names which the function is requesting for injection. This API is
+   * used by the injector to determine which services need to be injected into the function when the
+   * function is invoked. There are three ways in which the function can be annotated with the needed
+   * dependencies.
+   *
+   * #### Argument names
+   *
+   * The simplest form is to extract the dependencies from the arguments of the function. This is done
+   * by converting the function into a string using `toString()` method and extracting the argument
+   * names.
+   * ```js
+   *   // Given
+   *   function MyController($scope, $route) {
+   *     // ...
+   *   }
+   *
+   *   // Then
+   *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
+   * ```
+   *
+   * You can disallow this method by using strict injection mode.
+   *
+   * This method does not work with code minification / obfuscation. For this reason the following
+   * annotation strategies are supported.
+   *
+   * #### The `$inject` property
+   *
+   * If a function has an `$inject` property and its value is an array of strings, then the strings
+   * represent names of services to be injected into the function.
+   * ```js
+   *   // Given
+   *   var MyController = function(obfuscatedScope, obfuscatedRoute) {
+   *     // ...
+   *   }
+   *   // Define function dependencies
+   *   MyController['$inject'] = ['$scope', '$route'];
+   *
+   *   // Then
+   *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
+   * ```
+   *
+   * #### The array notation
+   *
+   * It is often desirable to inline Injected functions and that's when setting the `$inject` property
+   * is very inconvenient. In these situations using the array notation to specify the dependencies in
+   * a way that survives minification is a better choice:
+   *
+   * ```js
+   *   // We wish to write this (not minification / obfuscation safe)
+   *   injector.invoke(function($compile, $rootScope) {
+   *     // ...
+   *   });
+   *
+   *   // We are forced to write break inlining
+   *   var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
+   *     // ...
+   *   };
+   *   tmpFn.$inject = ['$compile', '$rootScope'];
+   *   injector.invoke(tmpFn);
+   *
+   *   // To better support inline function the inline annotation is supported
+   *   injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
+   *     // ...
+   *   }]);
+   *
+   *   // Therefore
+   *   expect(injector.annotate(
+   *      ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
+   *    ).toEqual(['$compile', '$rootScope']);
+   * ```
+   *
+   * @param {Function|Array.} fn Function for which dependent service names need to
+   * be retrieved as described above.
+   *
+   * @param {boolean=} [strictDi=false] Disallow argument name annotation inference.
+   *
+   * @returns {Array.} The names of the services which the function requires.

+   * @description
+   *
+   * Register a **provider function** with the {@link auto.$injector $injector}. Provider functions
+   * are constructor functions, whose instances are responsible for "providing" a factory for a
+   * service.
+   *
+   * Service provider names start with the name of the service they provide followed by `Provider`.
+   * For example, the {@link ng.$log $log} service has a provider called
+   * {@link ng.$logProvider $logProvider}.
+   *
+   * Service provider objects can have additional methods which allow configuration of the provider
+   * and its service. Importantly, you can configure what kind of service is created by the `$get`
+   * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
+   * method {@link ng.$logProvider#debugEnabled debugEnabled}
+   * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
+   * console or not.
+   *
+   * It is possible to inject other providers into the provider function,
+   * but the injected provider must have been defined before the one that requires it.
+   *
+   * @param {string} name The name of the instance. NOTE: the provider will be available under `name +
+                          'Provider'` key.
+   * @param {(Object|function())} provider If the provider is:
+   *
+   *   - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
+   *     {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
+   *   - `Constructor`: a new instance of the provider will be created using
+   *     {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.
+   *
+   * @returns {Object} registered provider instance
+  
+   * @example
+   *
+   * The following example shows how to create a simple event tracking service and register it using
+   * {@link auto.$provide#provider $provide.provider()}.
+   *
+   * ```js
+   *  // Define the eventTracker provider
+   *  function EventTrackerProvider() {

+   *
+   *    // A provider method for configuring where the tracked events should been saved
+   *    this.setTrackingUrl = function(url) {
+   *      trackingUrl = url;
+   *    };
+   *
+   *    // The service factory function
+   *    this.$get = ['$http', function($http) {
+   *      var trackedEvents = {};
+   *      return {
+   *        // Call this to track an event

+   *          var count = trackedEvents[event] || 0;
+   *          count += 1;
+   *          trackedEvents[event] = count;
+   *          return count;
+   *        },
+   *        // Call this to save the tracked events to the trackingUrl
+   *        save: function() {
+   *          $http.post(trackingUrl, trackedEvents);
+   *        }
+   *      };
+   *    }];
+   *  }
+   *

-       * @description Sets up an event listener to fire whenever the animation event (enter, leave, move, etc...)
-       *    has fired on the given element or among any of its children. Once the listener is fired, the provided callback
-       *    is fired with the following params:
-       *
-       * ```js
-       * $animate.on('enter', container,

-       * );
-       * ```
-       *
-       * 

-       * **Note**: Generally, the events that are fired correspond 1:1 to `$animate` method names,
-       * e.g. {@link ng.$animate#addClass addClass()} will fire `addClass`, and {@link ng.ngClass}
-       * will fire `addClass` if classes are added, and `removeClass` if classes are removed.
-       * However, there are two exceptions:
-       *
-       * 
    
-       *   
  • if both an {@link ng.$animate#addClass addClass()} and a
-       *   {@link ng.$animate#removeClass removeClass()} action are performed during the same
-       *   animation, the event fired will be `setClass`. This is true even for `ngClass`.
    • 
-       *   
  • an {@link ng.$animate#animate animate()} call that adds and removes classes will fire
-       *   the `setClass` event, but if it either removes or adds classes,
-       *   it will fire `animate` instead.

-       *     as well as among its children
-       * @param {Function} callback the callback function that will be fired when the listener is triggered.

-       * * `phase` - The phase of the animation. The two possible phases are **start** (when the animation starts) and **close** (when it ends).

-       *     * addClass - `{string|null}` - space-separated CSS classes to add to the element
-       *     * removeClass - `{string|null}` - space-separated CSS classes to remove from the element

-       *     * to - `{Object|null}` - CSS properties & values at the end of the animation
-       *
-       * Note that the callback does not trigger a scope digest. Wrap your call into a

+     * If set, specifies a vertical scroll-offset. This is often useful when there are fixed
+     * positioned elements at the top of the page, such as navbars, headers etc.
+     *
+     * `yOffset` can be specified in various ways:
+     * - **number**: A fixed number of pixels to be used as offset.


+     * - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return
+     *   a number representing the offset (in pixels).


+     * - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from
+     *   the top of the page to the element's bottom will be used as offset.

+     *   **Note**: The element will be taken into account only as long as its `position` is set to
+     *   `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust
+     *   their height and/or positioning according to the viewport's size.
+     *
+     * 

+     * 

+     * In order for `yOffset` to work properly, scrolling should take place on the document's root and
+     * not some child element.
+     * 

+     *
+     * @example
+       
+         
+           

+             Go to bottom

+     * animation will be blocked. Setting the `customFilter` value will only allow animations for
+     * which the filter function's return value is truthy.
+     *
+     * This allows to easily create arbitrarily complex rules for filtering animations, such as
+     * allowing specific events only, or enabling animations on specific subtrees of the DOM, etc.
+     * Filtering animations can also boost performance for low-powered devices, as well as
+     * applications containing a lot of structural operations.
+     *
+     * 

+     *   **Best Practice:**

+     *   filtering function can make your animations sluggish.

+       * to ensure that animation runs with the triggered DOM operation.
        *
-       * Example test:
+       * By default $animate doesn't trigger any animations. This is because the `ngAnimate` module isn't
+       * included and only when it is active then the animation hooks that `$animate` triggers will be
+       * functional. Once active then all structural `ng-` directives will trigger animations as they perform
+       * their DOM-related operations (enter, leave and move). Other directives such as `ngClass`,
+       * `ngShow`, `ngHide` and `ngMessages` also provide support for animations.
        *
-       * ```js
-       *  it('should behave like a cache', inject(function(superCache) {

-/**
- * @ngdoc service
- * @name $compile
- * @kind function
- *
- * @description
- * Compiles an HTML string or DOM into a template and produces a template function, which
- * can then be used to link {@link ng.$rootScope.Scope `scope`} and the template together.
- *
- * The compilation is a process of walking the DOM tree and matching DOM elements to
- * {@link ng.$compileProvider#directive directives}.
- *
- * 

- * **Note:** This document is an in-depth reference of all directive options.
- * For a gentle introduction to directives with examples of common use cases,
- * see the {@link guide/directive directive guide}.
- * 

- *
- * ## Comprehensive Directive API
- *
- * There are many different options for a directive.
- *
- * The difference resides in the return value of the factory function.
- * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}
- * that defines the directive properties, or just the `postLink` function (all other properties will have
- * the default values).
- *
- * 

- * **Best Practice:** It's recommended to use the "directive definition object" form.
- * 

- *
- * Here's an example directive declared with a Directive Definition Object:
- *
- * ```js
- *   var myModule = angular.module(...);
- *
- *   myModule.directive('directiveName', function factory(injectables) {
- *     var directiveDefinitionObject = {
- *       {@link $compile#-priority- priority}: 0,
- *       {@link $compile#-template- template}: '
', // or // function(tElement, tAttrs) { ... },
- *       // or
- *       // {@link $compile#-templateurl- templateUrl}: 'directive.html', // or // function(tElement, tAttrs) { ... },
- *       {@link $compile#-transclude- transclude}: false,
- *       {@link $compile#-restrict- restrict}: 'A',
- *       {@link $compile#-templatenamespace- templateNamespace}: 'html',
- *       {@link $compile#-scope- scope}: false,
- *       {@link $compile#-controller- controller}: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
- *       {@link $compile#-controlleras- controllerAs}: 'stringIdentifier',
- *       {@link $compile#-bindtocontroller- bindToController}: false,
- *       {@link $compile#-require- require}: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
- *       {@link $compile#-multielement- multiElement}: false,
- *       {@link $compile#-compile- compile}: function compile(tElement, tAttrs, transclude) {
- *         return {
- *            {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
- *            {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
- *         }
- *         // or
- *         // return function postLink( ... ) { ... }
- *       },
- *       // or
- *       // {@link $compile#-link- link}: {
- *       //  {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
- *       //  {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
- *       // }
- *       // or
- *       // {@link $compile#-link- link}: function postLink( ... ) { ... }
- *     };
- *     return directiveDefinitionObject;
- *   });
- * ```
- *
- * 

- * **Note:** Any unspecified options will use the default value. You can see the default values below.
- * 

- *
- * Therefore the above can be simplified as:
- *
- * ```js
- *   var myModule = angular.module(...);
- *
- *   myModule.directive('directiveName', function factory(injectables) {
- *     var directiveDefinitionObject = {
- *       link: function postLink(scope, iElement, iAttrs) { ... }
- *     };
- *     return directiveDefinitionObject;
- *     // or
- *     // return function postLink(scope, iElement, iAttrs) { ... }
- *   });
- * ```
- *
- * ### Life-cycle hooks
- * Directive controllers can provide the following methods that are called by AngularJS at points in the life-cycle of the
- * directive:
- * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
- *   had their bindings initialized (and before the pre & post linking functions for the directives on
- *   this element). This is a good place to put initialization code for your controller.
- * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
- *   `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
- *   object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a
- *   component such as cloning the bound value to prevent accidental mutation of the outer value. Note that this will
- *   also be called when your bindings are initialized.
- * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on
- *   changes. Any actions that you wish to take in response to the changes that you detect must be
- *   invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook
- *   could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not
- *   be detected by AngularJS's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;
- *   if detecting changes, you must store the previous value(s) for comparison to the current values.
- * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing
- *   external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in
- *   the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent
- *   components will have their `$onDestroy()` hook called before child components.
- * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link
- *   function this hook can be used to set up DOM event handlers and do direct DOM manipulation.
- *   Note that child elements that contain `templateUrl` directives will not have been compiled and linked since
- *   they are waiting for their template to load asynchronously and their own compilation and linking has been
- *   suspended until that occurs.
- *
- * #### Comparison with life-cycle hooks in the new Angular
- * The new Angular also uses life-cycle hooks for its components. While the AngularJS life-cycle hooks are similar there are
- * some differences that you should be aware of, especially when it comes to moving your code from AngularJS to Angular:
- *
- * * AngularJS hooks are prefixed with `$`, such as `$onInit`. Angular hooks are prefixed with `ng`, such as `ngOnInit`.
- * * AngularJS hooks can be defined on the controller prototype or added to the controller inside its constructor.
- *   In Angular you can only define hooks on the prototype of the Component class.
- * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in AngularJS than you would to
- *   `ngDoCheck` in Angular.
- * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be
- *   propagated throughout the application.
- *   Angular does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an
- *   error or do nothing depending upon the state of `enableProdMode()`.
- *
- * #### Life-cycle hook examples
- *
- * This example shows how you can check for mutations to a Date object even though the identity of the object
- * has not changed.
- *
- * 
- *   
- *     angular.module('do-check-module', [])
- *       .component('app', {
- *         template:
- *           'Month: ' +
- *           'Date: {{ $ctrl.date }}' +
- *           '',
- *         controller: function() {
- *           this.date = new Date();
- *           this.month = this.date.getMonth();
- *           this.updateDate = function() {
- *             this.date.setMonth(this.month);
- *           };
- *         }
- *       })
- *       .component('test', {
- *         bindings: { date: '<' },
- *         template:
- *           '
{{ $ctrl.log | json }}
',
- *         controller: function() {
- *           var previousValue;
- *           this.log = [];
- *           this.$doCheck = function() {
- *             var currentValue = this.date && this.date.valueOf();
- *             if (previousValue !== currentValue) {
- *               this.log.push('doCheck: date mutated: ' + this.date);
- *               previousValue = currentValue;
- *             }
- *           };
- *         }
- *       });
- *   
- *   
- *     
- *   
- * 
- *
- * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the
- * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large
- * arrays or objects can have a negative impact on your application performance)
- *
- * 
- *   
- *     

- *       
- *       
- *       
{{ items }}

- *       
- *     

- *   
- *   
- *      angular.module('do-check-module', [])
- *        .component('test', {
- *          bindings: { items: '<' },
- *          template:
- *            '
{{ $ctrl.log | json }}
',
- *          controller: function() {
- *            this.log = [];
- *
- *            this.$doCheck = function() {
- *              if (this.items_ref !== this.items) {
- *                this.log.push('doCheck: items changed');
- *                this.items_ref = this.items;
- *              }
- *              if (!angular.equals(this.items_clone, this.items)) {
- *                this.log.push('doCheck: items mutated');
- *                this.items_clone = angular.copy(this.items);
- *              }
- *            };
- *          }
- *        });
- *   
- * 
- *
- *
- * ### Directive Definition Object
- *
- * The directive definition object provides instructions to the {@link ng.$compile
- * compiler}. The attributes are:
- *
- * #### `multiElement`
- * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between
- * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
- * together as the directive elements. It is recommended that this feature be used on directives
- * which are not strictly behavioral (such as {@link ngClick}), and which
- * do not manipulate or replace child nodes (such as {@link ngInclude}).
- *
- * #### `priority`
- * When there are multiple directives defined on a single DOM element, sometimes it
- * is necessary to specify the order in which the directives are applied. The `priority` is used
- * to sort the directives before their `compile` functions get called. Priority is defined as a
- * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
- * are also run in priority order, but post-link functions are run in reverse order. The order
- * of directives with the same priority is undefined. The default priority is `0`.
- *
- * #### `terminal`
- * If set to true then the current `priority` will be the last set of directives
- * which will execute (any directives at the current priority will still execute
- * as the order of execution on same `priority` is undefined). Note that expressions
- * and other directives used in the directive's template will also be excluded from execution.
- *
- * #### `scope`
- * The scope property can be `false`, `true`, or an object:
- *
- * * **`false` (default):** No scope will be created for the directive. The directive will use its
- * parent's scope.
- *
- * * **`true`:** A new child scope that prototypically inherits from its parent will be created for
- * the directive's element. If multiple directives on the same element request a new scope,
- * only one new scope is created.
- *
- * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's template.
- * The 'isolate' scope differs from normal scope in that it does not prototypically
- * inherit from its parent scope. This is useful when creating reusable components, which should not
- * accidentally read or modify data in the parent scope. Note that an isolate scope
- * directive without a `template` or `templateUrl` will not apply the isolate scope
- * to its children elements.
- *
- * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
- * directive's element. These local properties are useful for aliasing values for templates. The keys in
- * the object hash map to the name of the property on the isolate scope; the values define how the property
- * is bound to the parent scope, via matching attributes on the directive's element:
- *
- * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
- *   always a string since DOM attributes are strings. If no `attr` name is specified then the
- *   attribute name is assumed to be the same as the local name. Given `` and the isolate scope definition `scope: { localName:'@myAttr' }`,
- *   the directive's scope property `localName` will reflect the interpolated value of `hello
- *   {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's
- *   scope. The `name` is read from the parent scope (not the directive's scope).
- *
- * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression
- *   passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.
- *   If no `attr` name is specified then the attribute name is assumed to be the same as the local
- *   name. Given `` and the isolate scope definition `scope: {
- *   localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the
- *   value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in
- *   `localModel` and vice versa. If the binding expression is non-assignable, or if the attribute
- *   isn't  optional and doesn't exist, an exception
- *   ({@link error/$compile/nonassign `$compile:nonassign`}) will be thrown upon discovering changes
- *   to the local value, since it will be impossible to sync them back to the parent scope.
- *
- *   By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
- *   method is used for tracking changes, and the equality check is based on object identity.
- *   However, if an object literal or an array literal is passed as the binding expression, the
- *   equality check is done by value (using the {@link angular.equals} function). It's also possible
- *   to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection
- *   `$watchCollection`}: use `=*` or `=*attr`
- *
-  * * `<` or `` and directive definition of
- *   `scope: { localModel:'` and the isolate scope definition `scope: {
- *   localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
- *   the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
- *   via an expression to the parent scope. This can be done by passing a map of local variable names
- *   and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
- *   then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
- *
- * All 4 kinds of bindings (`@`, `=`, `<`, and `&`) can be made optional by adding `?` to the expression.
- * The marker must come after the mode and before the attribute name.
- * See the {@link error/$compile/iscp Invalid Isolate Scope Definition error} for definition examples.
- * This is useful to refine the interface directives provide.
- * One subtle difference between optional and non-optional happens **when the binding attribute is not
- * set**:
- * - the binding is optional: the property will not be defined
- * - the binding is not optional: the property is defined
- *
- * ```js
- *app.directive('testDir', function() {
-    return {
-      scope: {
-        notoptional: '=',
-        optional: '=?',
-      },
-      bindToController: true,
-      controller: function() {
-        this.$onInit = function() {
-          console.log(this.hasOwnProperty('notoptional')) // true
-          console.log(this.hasOwnProperty('optional')) // false
-        }
-      }
+    function cacheStateAndFireUrlChange() {
+      pendingLocation = null;
+      fireStateOrUrlChange();
     }
-  })
- *```
- *
- *
- * ##### Combining directives with different scope defintions
- *
- * In general it's possible to apply more than one directive to one element, but there might be limitations
- * depending on the type of scope required by the directives. The following points will help explain these limitations.
- * For simplicity only two directives are taken into account, but it is also applicable for several directives:
- *
- * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
- * * **child scope** + **no scope** =>  Both directives will share one single child scope
- * * **child scope** + **child scope** =>  Both directives will share one single child scope
- * * **isolated scope** + **no scope** =>  The isolated directive will use it's own created isolated scope. The other directive will use
- * its parent's scope
- * * **isolated scope** + **child scope** =>  **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
- * be applied to the same element.
- * * **isolated scope** + **isolated scope**  =>  **Won't work!** Only one scope can be related to one element. Therefore these directives
- * cannot be applied to the same element.
- *
- *
- * #### `bindToController`
- * This property is used to bind scope properties directly to the controller. It can be either
- * `true` or an object hash with the same format as the `scope` property.
- *
- * When an isolate scope is used for a directive (see above), `bindToController: true` will
- * allow a component to have its properties bound to the controller, rather than to scope.
- *
- * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
- * properties. You can access these bindings once they have been initialized by providing a controller method called
- * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
- * initialized.
- *
- * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.
- * This will set up the scope bindings to the controller directly. Note that `scope` can still be used
- * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate
- * scope (useful for component directives).
- *
- * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.
- *
- *
- * #### `controller`
- * Controller constructor function. The controller is instantiated before the
- * pre-linking phase and can be accessed by other directives (see
- * `require` attribute). This allows the directives to communicate with each other and augment
- * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
- *
- * * `$scope` - Current scope associated with the element
- * * `$element` - Current element
- * * `$attrs` - Current attributes object for the element
- * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
- *   `function([scope], cloneLinkingFn, futureParentElement, slotName)`:
- *    * `scope`: (optional) override the scope.
- *    * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.
- *    * `futureParentElement` (optional):
- *        * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
- *        * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
- *        * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
- *          and when the `cloneLinkingFn` is passed,
- *          as those elements need to created and cloned in a special way when they are defined outside their
- *          usual containers (e.g. like ``).
- *        * See also the `directive.templateNamespace` property.
- *    * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)
- *      then the default transclusion is provided.
- *    The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns
- *    `true` if the specified slot contains content (i.e. one or more DOM nodes).
- *
- * #### `require`
- * Require another directive and inject its controller as the fourth argument to the linking function. The
- * `require` property can be a string, an array or an object:
- * * a **string** containing the name of the directive to pass to the linking function
- * * an **array** containing the names of directives to pass to the linking function. The argument passed to the
- * linking function will be an array of controllers in the same order as the names in the `require` property
- * * an **object** whose property values are the names of the directives to pass to the linking function. The argument
- * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding
- * controllers.
- *
- * If the `require` property is an object and `bindToController` is truthy, then the required controllers are
- * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers
- * have been constructed but before `$onInit` is called.
- * If the name of the required controller is the same as the local name (the key), the name can be
- * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.
- * See the {@link $compileProvider#component} helper for an example of how this can be used.
- * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is
- * raised (unless no link function is specified and the required controllers are not being bound to the directive
- * controller, in which case error checking is skipped). The name can be prefixed with:
- *
- * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
- * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
- * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
- * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
- * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
- *   `null` to the `link` fn if not found.
- * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
- *   `null` to the `link` fn if not found.
- *
- *
- * #### `controllerAs`
- * Identifier name for a reference to the controller in the directive's scope.
- * This allows the controller to be referenced from the directive template. This is especially
- * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
- * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
- * `controllerAs` reference might overwrite a property that already exists on the parent scope.
- *
- *
- * #### `restrict`
- * String of subset of `EACM` which restricts the directive to a specific directive
- * declaration style. If omitted, the defaults (elements and attributes) are used.
- *
- * * `E` - Element name (default): ``
- * * `A` - Attribute (default): `
`
- * * `C` - Class: `
`
- * * `M` - Comment: ``
- *
- *
- * #### `templateNamespace`
- * String representing the document type used by the markup in the template.
- * AngularJS needs this information as those elements need to be created and cloned
- * in a special way when they are defined outside their usual containers like `` and ``.
- *
- * * `html` - All root nodes in the template are HTML. Root nodes may also be
- *   top-level elements such as `` or ``.
- * * `svg` - The root nodes in the template are SVG elements (excluding ``).
- * * `math` - The root nodes in the template are MathML elements (excluding ``).
- *
- * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
- *
- * #### `template`
- * HTML markup that may:
- * * Replace the contents of the directive's element (default).
- * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
- * * Wrap the contents of the directive's element (if `transclude` is true).
- *
- * Value may be:
- *
- * * A string. For example `
{{delete_str}}
`.
- * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
- *   function api below) and returns a string value.
- *
- *
- * #### `templateUrl`
- * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
- *
- * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
- * for later when the template has been resolved.  In the meantime it will continue to compile and link
- * sibling and parent elements as though this element had not contained any directives.
- *
- * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
- * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
- * case when only one deeply nested directive has `templateUrl`.
- *
- * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
- *
- * You can specify `templateUrl` as a string representing the URL or as a function which takes two
- * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
- * a string value representing the url.  In either case, the template URL is passed through {@link
- * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
- *
- *
- * #### `replace`
- * 

- * **Note:** `replace` is deprecated in AngularJS and has been removed in the new Angular (v2+).
- * 

- *
- * Specifies what the template should replace. Defaults to `false`.
- *
- * * `true` - the template will replace the directive's element.
- * * `false` - the template will replace the contents of the directive's element.
- *
- * The replacement process migrates all of the attributes / classes from the old element to the new
- * one. See the {@link guide/directive#template-expanding-directive
- * Directives Guide} for an example.
- *
- * There are very few scenarios where element replacement is required for the application function,
- * the main one being reusable custom components that are used within SVG contexts
- * (because SVG doesn't work with custom elements in the DOM tree).
- *
- * #### `transclude`
- * Extract the contents of the element where the directive appears and make it available to the directive.
- * The contents are compiled and provided to the directive as a **transclusion function**. See the
- * {@link $compile#transclusion Transclusion} section below.
- *
- *
- * #### `compile`
- *
- * ```js
- *   function compile(tElement, tAttrs, transclude) { ... }
- * ```
- *
- * The compile function deals with transforming the template DOM. Since most directives do not do
- * template transformation, it is not used often. The compile function takes the following arguments:
- *
- *   * `tElement` - template element - The element where the directive has been declared. It is
- *     safe to do template transformation on the element and child elements only.
- *
- *   * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
- *     between all directive compile functions.
- *
- *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
- *
- * 

- * **Note:** The template instance and the link instance may be different objects if the template has
- * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
- * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
- * should be done in a linking function rather than in a compile function.
- * 

-
- * 

- * **Note:** The compile function cannot handle directives that recursively use themselves in their
- * own templates or compile functions. Compiling these directives results in an infinite loop and
- * stack overflow errors.
- *
- * This can be avoided by manually using $compile in the postLink function to imperatively compile
- * a directive's template instead of relying on automatic template compilation via `template` or
- * `templateUrl` declaration or manual compilation inside the compile function.
- * 

- *
- * 

- * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
- *   e.g. does not know about the right outer scope. Please use the transclude function that is passed
- *   to the link function instead.
- * 

-
- * A compile function can have a return value which can be either a function or an object.
- *
- * * returning a (post-link) function - is equivalent to registering the linking function via the
- *   `link` property of the config object when the compile function is empty.
- *
- * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
- *   control when a linking function should be called during the linking phase. See info about
- *   pre-linking and post-linking functions below.
- *
- *
- * #### `link`
- * This property is used only if the `compile` property is not defined.
- *
- * ```js
- *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
- * ```
- *
- * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
- * executed after the template has been cloned. This is where most of the directive logic will be
- * put.
- *
- *   * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
- *     directive for registering {@link ng.$rootScope.Scope#$watch watches}.
- *
- *   * `iElement` - instance element - The element where the directive is to be used. It is safe to
- *     manipulate the children of the element only in `postLink` function since the children have
- *     already been linked.
- *
- *   * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
- *     between all directive linking functions.
- *
- *   * `controller` - the directive's required controller instance(s) - Instances are shared
- *     among all directives, which allows the directives to use the controllers as a communication
- *     channel. The exact value depends on the directive's `require` property:
- *       * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
- *       * `string`: the controller instance
- *       * `array`: array of controller instances
- *
- *     If a required controller cannot be found, and it is optional, the instance is `null`,
- *     otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
- *
- *     Note that you can also require the directive's own controller - it will be made available like
- *     any other controller.
- *
- *   * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
- *     This is the same as the `$transclude` parameter of directive controllers,
- *     see {@link ng.$compile#-controller- the controller section for details}.
- *     `function([scope], cloneLinkingFn, futureParentElement)`.
- *
- * #### Pre-linking function
- *
- * Executed before the child elements are linked. Not safe to do DOM transformation since the
- * compiler linking function will fail to locate the correct elements for linking.
- *
- * #### Post-linking function
- *
- * Executed after the child elements are linked.
- *
- * Note that child elements that contain `templateUrl` directives will not have been compiled
- * and linked since they are waiting for their template to load asynchronously and their own
- * compilation and linking has been suspended until that occurs.
- *
- * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
- * for their async templates to be resolved.
- *
- *
- * ### Transclusion
- *
- * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
- * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
- * scope from where they were taken.
- *
- * Transclusion is used (often with {@link ngTransclude}) to insert the
- * original contents of a directive's element into a specified place in the template of the directive.
- * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
- * content has access to the properties on the scope from which it was taken, even if the directive
- * has isolated scope.
- * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
- *
- * This makes it possible for the widget to have private state for its template, while the transcluded
- * content has access to its originating scope.
- *
- * 

- * **Note:** When testing an element transclude directive you must not place the directive at the root of the
- * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
- * Testing Transclusion Directives}.
- * 

- *
- * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the
- * directive's element, the entire element or multiple parts of the element contents:
- *
- * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
- * * `'element'` - transclude the whole of the directive's element including any directives on this
- *   element that defined at a lower priority than this directive. When used, the `template`
- *   property is ignored.
- * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template.
- *
- * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.
- *
- * This object is a map where the keys are the name of the slot to fill and the value is an element selector
- * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)
- * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).
- *
- * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}
- *
- * If the element selector is prefixed with a `?` then that slot is optional.
- *
- * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `` elements to
- * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.
- *
- * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements
- * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call
- * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and
- * injectable into the directive's controller.
- *
- *
- * #### Transclusion Functions
- *
- * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
- * function** to the directive's `link` function and `controller`. This transclusion function is a special
- * **linking function** that will return the compiled contents linked to a new transclusion scope.
- *
- * 

- * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
- * ngTransclude will deal with it for us.
- * 

- *
- * If you want to manually control the insertion and removal of the transcluded content in your directive
- * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
- * object that contains the compiled DOM, which is linked to the correct transclusion scope.
- *
- * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
- * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
- * content and the `scope` is the newly created transclusion scope, which the clone will be linked to.
- *
- * 

- * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function
- * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
- * 

- *
- * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
- * attach function**:
- *
- * ```js
- * var transcludedContent, transclusionScope;
- *
- * $transclude(function(clone, scope) {
- *   element.append(clone);
- *   transcludedContent = clone;
- *   transclusionScope = scope;
- * });
- * ```
- *
- * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
- * associated transclusion scope:
- *
- * ```js
- * transcludedContent.remove();
- * transclusionScope.$destroy();
- * ```
- *
- * 

- * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
- * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
- * then you are also responsible for calling `$destroy` on the transclusion scope.
- * 

- *
- * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
- * automatically destroy their transcluded clones as necessary so you do not need to worry about this if
- * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
- *
- *
- * #### Transclusion Scopes
- *
- * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
- * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
- * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
- * was taken.
- *
- * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
- * like this:
- *
- * ```html
- * 

- *   

- *     

- *     

- *   

- * 

- * ```
- *
- * The `$parent` scope hierarchy will look like this:
- *
-   ```
-   - $rootScope
-     - isolate
-       - transclusion
-   ```
- *
- * but the scopes will inherit prototypically from different scopes to their `$parent`.
- *
-   ```
-   - $rootScope
-     - transclusion
-   - isolate
-   ```
- *
- *
- * ### Attributes
- *
- * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
- * `link()` or `compile()` functions. It has a variety of uses.
- *
- * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:
- *   'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access
- *   to the attributes.
- *
- * * *Directive inter-communication:* All directives share the same instance of the attributes
- *   object which allows the directives to use the attributes object as inter directive
- *   communication.
- *
- * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
- *   allowing other directives to read the interpolated value.
- *
- * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
- *   that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
- *   the only way to easily get the actual value because during the linking phase the interpolation
- *   hasn't been evaluated yet and so the value is at this time set to `undefined`.
- *
- * ```js
- * function linkingFn(scope, elm, attrs, ctrl) {
- *   // get the attribute value
- *   console.log(attrs.ngModel);
- *
- *   // change the attribute
- *   attrs.$set('ngModel', 'new value');
- *
- *   // observe changes to interpolated attribute
- *   attrs.$observe('ngModel', function(value) {
- *     console.log('ngModel has changed value to ' + value);
- *   });
- * }
- * ```
- *
- * ## Example
- *
- * 

- * **Note**: Typically directives are registered with `module.directive`. The example below is
- * to illustrate how `$compile` works.
- * 

- *
- 
-   
-    
-    

-       

-       

-      

-    

-   
-   
-     it('should auto compile', function() {
-       var textarea = $('textarea');
-       var output = $('div[compile]');
-       // The initial state reads 'Hello AngularJS'.
-       expect(output.getText()).toBe('Hello AngularJS');
-       textarea.clear();
-       textarea.sendKeys('{{name}}!');
-       expect(output.getText()).toBe('AngularJS!');
-     });
-   
- 
 
- *
- *
- * @param {string|DOMElement} element Element or HTML string to compile into a template function.
- * @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives - DEPRECATED.
- *
- * 

- * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it
- *   e.g. will not use the right outer scope. Please pass the transclude function as a
- *   `parentBoundTranscludeFn` to the link function instead.
- * 

- *
- * @param {number} maxPriority only apply directives lower than given priority (Only effects the
- *                 root element(s), not their children)
- * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template
- * (a DOM element/tree) to a scope. Where:
- *
- *  * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
- *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
- *  `template` and call the `cloneAttachFn` function allowing the caller to attach the
- *  cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
- *  called as: 
 `cloneAttachFn(clonedElement, scope)` where:
- *
- *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
- *      * `scope` - is the current scope with which the linking function is working with.
- *
- *  * `options` - An optional object hash with linking options. If `options` is provided, then the following
- *  keys may be used to control linking behavior:
- *
- *      * `parentBoundTranscludeFn` - the transclude function made available to
- *        directives; if given, it will be passed through to the link functions of
- *        directives found in `element` during compilation.
- *      * `transcludeControllers` - an object hash with keys that map controller names
- *        to a hash with the key `instance`, which maps to the controller instance;
- *        if given, it will make the controllers available to directives on the compileNode:
- *        ```
- *        {
- *          parent: {
- *            instance: parentControllerInstance
- *          }
- *        }
- *        ```
- *      * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add
- *        the cloned elements; only needed for transcludes that are allowed to contain non html
- *        elements (e.g. SVG elements). See also the directive.controller property.
- *
- * Calling the linking function returns the element of the template. It is either the original
- * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
- *
- * After linking the view is not updated until after a call to $digest which typically is done by
- * AngularJS automatically.
- *
- * If you need access to the bound view, there are two ways to do it:
- *
- * - If you are not asking the linking function to clone the template, create the DOM element(s)
- *   before you send them to the compiler and keep this reference around.
- *   ```js
- *     var element = $compile('
{{total}}
')(scope);
- *   ```
- *
- * - if on the other hand, you need the element to be cloned, the view reference from the original
- *   example would not point to the clone, but rather to the original template that was cloned. In
- *   this case, you can access the clone via the cloneAttachFn:
- *   ```js
- *     var templateElement = angular.element('
{{total}}
'),
- *         scope = ....;
- *
- *     var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
- *       //attach the clone to DOM document at the right place
- *     });
- *
- *     //now we have reference to the cloned DOM via `clonedElement`
- *   ```
- *
- *
- * For information on how the compiler works, see the
- * {@link guide/compiler AngularJS HTML Compiler} section of the Developer Guide.
- *
- * @knownIssue
- *
- * ### Double Compilation
- *
-   Double compilation occurs when an already compiled part of the DOM gets
-   compiled again. This is an undesired effect and can lead to misbehaving directives, performance issues,
-   and memory leaks. Refer to the Compiler Guide {@link guide/compiler#double-compilation-and-how-to-avoid-it
-   section on double compilation} for an in-depth explanation and ways to avoid it.
+    // This variable should be used *only* inside the cacheState function.
+    var lastCachedState = null;
+    function cacheState() {
+      // This should be the only place in $browser where `history.state` is read.
+      cachedState = getCurrentState();
+      cachedState = isUndefined(cachedState) ? null : cachedState;
 
- * @knownIssue

+      if (equals(cachedState, lastCachedState)) {
+        cachedState = lastCachedState;

-   ### Issues with `replace: true`
- *
- * 

- *   **Note**: {@link $compile#-replace- `replace: true`} is deprecated and not recommended to use,
- *   mainly due to the issues listed here. It has been completely removed in the new Angular.
- * 

- *
- * #### Attribute values are not merged
- *
- * When a `replace` directive encounters the same attribute on the original and the replace node,
- * it will simply deduplicate the attribute and join the values with a space or with a `;` in case of
- * the `style` attribute.
- * ```html
- * Original Node: 
- * Replace Template: 
- * Result: 
- * ```
- *
- * That means attributes that contain AngularJS expressions will not be merged correctly, e.g.
- * {@link ngShow} or {@link ngClass} will cause a {@link $parse} error:
- *
- * ```html
- * Original Node: 
- * Replace Template: 
- * Result: 
- * ```
- *
- * See issue [#5695](https://github.com/angular/angular.js/issues/5695).
- *
- * #### Directives are not deduplicated before compilation
- *
- * When the original node and the replace template declare the same directive(s), they will be
- * {@link guide/compiler#double-compilation-and-how-to-avoid-it compiled twice} because the compiler
- * does not deduplicate them. In many cases, this is not noticable, but e.g. {@link ngModel} will
- * attach `$formatters` and `$parsers` twice.
- *
- * See issue [#2573](https://github.com/angular/angular.js/issues/2573).
- *
- * #### `transclude: element` in the replace template root can have unexpected effects
- *
- * When the replace template has a directive at the root node that uses
- * {@link $compile#-transclude- `transclude: element`}, e.g.
- * {@link ngIf} or {@link ngRepeat}, the DOM structure or scope inheritance can be incorrect.
- * See the following issues:
- *
- * - Incorrect scope on replaced element:
- * [#9837](https://github.com/angular/angular.js/issues/9837)
- * - Different DOM between `template` and `templateUrl`:
- * [#10612](https://github.com/angular/angular.js/issues/14326)

-/**
- * @ngdoc directive
- * @name ngProp
- * @restrict A
- * @element ANY
- *
- * @usage
- *
- * ```html
- * 
- * 
- * ```
- *
- * or with uppercase letters in property (e.g. "propName"):
- *
- *
- * ```html
- * 
- * 
- * ```
- *
- *
- * @description
- * The `ngProp` directive binds an expression to a DOM element property.
- * `ngProp` allows writing to arbitrary properties by including
- * the property name in the attribute, e.g. `ng-prop-value="'my value'"` binds 'my value' to
- * the `value` property.
- *
- * Usually, it's not necessary to write to properties in AngularJS, as the built-in directives
- * handle the most common use cases (instead of the above example, you would use {@link ngValue}).
- *
- * However, [custom elements](https://developer.mozilla.org/docs/Web/Web_Components/Using_custom_elements)
- * often use custom properties to hold data, and `ngProp` can be used to provide input to these
- * custom elements.
- *
- * ## Binding to camelCase properties
- *
- * Since HTML attributes are case-insensitive, camelCase properties like `innerHTML` must be escaped.
- * AngularJS uses the underscore (_) in front of a character to indicate that it is uppercase, so
- * `innerHTML`  must be written as `ng-prop-inner_h_t_m_l="expression"` (Note that this is just an
- * example, and for binding HTML {@link ngBindHtml} should be used.
- *
- * ## Security
- *
- * Binding expressions to arbitrary properties poses a security risk, as  properties like `innerHTML`
- * can insert potentially dangerous HTML into the application, e.g. script tags that execute
- * malicious code.
- * For this reason, `ngProp` applies Strict Contextual Escaping with the {@link ng.$sce $sce service}.
- * This means vulnerable properties require their content to be "trusted", based on the
- * context of the property. For example, the `innerHTML` is in the `HTML` context, and the
- * `iframe.src` property is in the `RESOURCE_URL` context, which requires that values written to
- * this property are trusted as a `RESOURCE_URL`.
- *
- * This can be set explicitly by calling $sce.trustAs(type, value) on the value that is
- * trusted before passing it to the `ng-prop-*` directive. There are exist shorthand methods for
- * each context type in the form of {@link ng.$sce#trustAsResourceUrl $sce.trustAsResourceUrl()} et al.
- *
- * In some cases you can also rely upon automatic sanitization of untrusted values - see below.
- *
- * Based on the context, other options may exist to mark a value as trusted / configure the behavior
- * of {@link ng.$sce}. For example, to restrict the `RESOURCE_URL` context to specific origins, use
- * the {@link $sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist()}
- * and {@link $sceDelegateProvider#resourceUrlBlacklist resourceUrlBlacklist()}.
- *
- * {@link ng.$sce#what-trusted-context-types-are-supported- Find out more about the different context types}.
- *
- * ### HTML Sanitization
- *
- * By default, `$sce` will throw an error if it detects untrusted HTML content, and will not bind the
- * content.
- * However, if you include the {@link ngSanitize ngSanitize module}, it will try to sanitize the
- * potentially dangerous HTML, e.g. strip non-whitelisted tags and attributes when binding to
- * `innerHTML`.
- *
- * @example
- * ### Binding to different contexts
- *
- * 
- *   
- *     angular.module('exampleNgProp', [])
- *       .component('main', {
- *         templateUrl: 'main.html',
- *         controller: function($sce) {
- *           this.safeContent = 'Safe content';
- *           this.unsafeContent = '';
- *           this.trustedUnsafeContent = $sce.trustAsHtml(this.unsafeContent);
- *         }
- *       });
- *   
- *   
- *     

- *       

- *         Binding to a property without security context:
- *         

- *         innerText (safeContent)
- *       

- *
- *       

- *         "Safe" content that requires a security context will throw because the contents could potentially be dangerous ...
- *         

- *         innerHTML (safeContent)
- *       

- *
- *       

- *         ... so that actually dangerous content cannot be executed:
- *         

- *         innerHTML (unsafeContent)
- *       

- *
- *       

- *         ... but unsafe Content that has been trusted explicitly works - only do this if you are 100% sure!
- *         

- *         innerHTML (trustedUnsafeContent)
- *       

- *     

- *   
- *   
- *     

- *   
- *   
- *     .prop-unit {
- *       margin-bottom: 10px;
- *     }
- *
- *     .prop-binding {
- *       min-height: 30px;
- *       border: 1px solid blue;
- *     }
- *
- *     .prop-note {
- *       font-family: Monospace;
- *     }
- *   
- * 
- *
- *
- * @example
- * ### Binding to innerHTML with ngSanitize
- *
- * 
- *   
- *     angular.module('exampleNgProp', ['ngSanitize'])
- *       .component('main', {
- *         templateUrl: 'main.html',
- *         controller: function($sce) {
- *           this.safeContent = 'Safe content';
- *           this.unsafeContent = '';
- *           this.trustedUnsafeContent = $sce.trustAsHtml(this.unsafeContent);
- *         }

-/** @ngdoc directive
- * @name ngOn
- * @restrict A
- * @element ANY
- *
- * @usage
- *
- * ```html
- * 
- * 
- * ```
- *
- * or with uppercase letters in property (e.g. "eventName"):
- *
- *
- * ```html
- * 
- * 
- * ```
- *
- * @description
- * The `ngOn` directive adds an event listener to a DOM element via
- * {@link angular.element angular.element().on()}, and evaluates an expression when the event is
- * fired.
- * `ngOn` allows adding listeners for arbitrary events by including
- * the event name in the attribute, e.g. `ng-on-drop="onDrop()"` executes the 'onDrop()' expression
- * when the `drop` event is fired.
- *
- * AngularJS provides specific directives for many events, such as {@link ngClick}, so in most
- * cases it is not necessary to use `ngOn`. However, AngularJS does not support all events
- * (e.g. the `drop` event in the example above), and new events might be introduced in later DOM
- * standards.
- *
- * Another use-case for `ngOn` is listening to
- * [custom events](https://developer.mozilla.org/docs/Web/Guide/Events/Creating_and_triggering_events)
- * fired by
- * [custom elements](https://developer.mozilla.org/docs/Web/Web_Components/Using_custom_elements).
- *
- * ## Binding to camelCase properties
- *
- * Since HTML attributes are case-insensitive, camelCase properties like `myEvent` must be escaped.
- * AngularJS uses the underscore (_) in front of a character to indicate that it is uppercase, so
- * `myEvent` must be written as `ng-on-my_event="expression"`.
- *
- * @example
- * ### Bind to built-in DOM events
- *
- * 
- *   
- *     angular.module('exampleNgOn', [])
- *       .component('main', {
- *         templateUrl: 'main.html',
- *         controller: function() {
- *           this.clickCount = 0;
- *           this.mouseoverCount = 0;
- *
- *           this.loadingState = 0;
- *         }
- *       });
- *   
- *   
- *     

- *       This is equivalent to `ngClick` and `ngMouseover`:

- *       

- *       clickCount: {{$ctrl.clickCount}}

- *       mouseover: {{$ctrl.mouseoverCount}}
- *
- *       

- *
- *       For the `error` and `load` event on images no built-in AngularJS directives exist:

- *       

- *       

- *         Image is loading
- *         Image load error
- *         Image loaded successfully
- *       

- *     

- *   
- *   
- *     

- *   
- * 
- *
- *
- * @example
- * ### Bind to custom DOM events
- *
- * 
- *   
- *     angular.module('exampleNgOn', [])
- *       .component('main', {
- *         templateUrl: 'main.html',
- *         controller: function() {
- *           this.eventLog = '';
- *
- *           this.listener = function($event) {
- *             this.eventLog = 'Event with type "' + $event.type + '" fired at ' + $event.detail;
- *           };
- *         }
- *       })
- *       .component('childComponent', {
- *         templateUrl: 'child.html',
- *         controller: function($element) {
- *           this.fireEvent = function() {
- *             var event = new CustomEvent('customtype', { detail: new Date()});
- *
- *             $element[0].dispatchEvent(event);
- *           };
- *         }
- *       });

-   * In order to make the definition easier, components enforce best practices like use of `controllerAs`,
-   * `bindToController`. They always have **isolate scope** and are restricted to elements.
+   *  var cache = $cacheFactory('cacheId');
+   *  expect($cacheFactory.get('cacheId')).toBe(cache);
+   *  expect($cacheFactory.get('noSuchCacheId')).not.toBeDefined();
    *
-   * Here are a few examples of how you would usually define components:
+   *  cache.put("key", "value");
+   *  cache.put("another key", "another value");
    *
-   * ```js
-   *   var myMod = angular.module(...);
-   *   myMod.component('myComp', {
-   *     template: '
My name is {{$ctrl.name}}
',
-   *     controller: function() {
-   *       this.name = 'shahar';
-   *     }
-   *   });
+   *  // We've specified no options on creation
+   *  expect(cache.info()).toEqual({id: 'cacheId', size: 2});
    *
-   *   myMod.component('myComp', {
-   *     template: '
My name is {{$ctrl.name}}
',
-   *     bindings: {name: '@'}
-   *   });
+   * ```
    *
-   *   myMod.component('myComp', {
-   *     templateUrl: 'views/my-comp.html',
-   *     controller: 'MyCtrl',
-   *     controllerAs: 'ctrl',
-   *     bindings: {name: '@'}
-   *   });
    *
-   * ```

-   * The default value is true.
+   * `$templateCache` is a {@link $cacheFactory.Cache Cache object} created by the
+   * {@link ng.$cacheFactory $cacheFactory}.
+   *
+   * The first time a template is used, it is loaded in the template cache for quick retrieval. You
+   * can load templates directly into the cache in a `script` tag, by using {@link $templateRequest},
+   * or by consuming the `$templateCache` service directly.
+   *
+   * Adding via the `script` tag:
+   *
+   * ```html
+   *   
+   * ```
+   *
+   * **Note:** the `script` tag containing the template does not need to be included in the `head` of
+   * the document, but it must be a descendent of the {@link ng.$rootElement $rootElement} (e.g.
+   * element with {@link ngApp} attribute), otherwise the template will be ignored.
+   *
+   * Adding via the `$templateCache` service:
+   *
+   * ```js
+   * var myApp = angular.module('myApp', []);
+   * myApp.run(function($templateCache) {
+   *   $templateCache.put('templateId.html', 'This is the content of the template');
+   * });
+   * ```
+   *
+   * To retrieve the template later, simply use it in your component:
+   * ```js
+   * myApp.component('myComponent', {
+   *    templateUrl: 'templateId.html'
+   * });
+   * ```
+   *
+   * or get it via the `$templateCache` service:
+   * ```js
+   * $templateCache.get('templateId.html')
+   * ```

+   * **Note:** This document is an in-depth reference of all directive options.
+   * For a gentle introduction to directives with examples of common use cases,
+   * see the {@link guide/directive directive guide}.
+   * 

+   *
+   * ## Comprehensive Directive API
+   *
+   * There are many different options for a directive.
+   *
+   * The difference resides in the return value of the factory function.
+   * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}
+   * that defines the directive properties, or just the `postLink` function (all other properties will have
+   * the default values).
+   *
+   * 

+   * **Best Practice:** It's recommended to use the "directive definition object" form.
+   * 

+   *
+   * Here's an example directive declared with a Directive Definition Object:
+   *
+   * ```js
+   *   var myModule = angular.module(...);
+   *
+   *   myModule.directive('directiveName', function factory(injectables) {
+   *     var directiveDefinitionObject = {
+   *       {@link $compile#-priority- priority}: 0,
+   *       {@link $compile#-template- template}: '
', // or // function(tElement, tAttrs) { ... },
+   *       // or
+   *       // {@link $compile#-templateurl- templateUrl}: 'directive.html', // or // function(tElement, tAttrs) { ... },
+   *       {@link $compile#-transclude- transclude}: false,
+   *       {@link $compile#-restrict- restrict}: 'A',
+   *       {@link $compile#-templatenamespace- templateNamespace}: 'html',
+   *       {@link $compile#-scope- scope}: false,
+   *       {@link $compile#-controller- controller}: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
+   *       {@link $compile#-controlleras- controllerAs}: 'stringIdentifier',
+   *       {@link $compile#-bindtocontroller- bindToController}: false,
+   *       {@link $compile#-require- require}: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
+   *       {@link $compile#-multielement- multiElement}: false,
+   *       {@link $compile#-compile- compile}: function compile(tElement, tAttrs, transclude) {
+   *         return {
+   *            {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
+   *            {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
+   *         }
+   *         // or
+   *         // return function postLink( ... ) { ... }
+   *       },
+   *       // or
+   *       // {@link $compile#-link- link}: {
+   *       //  {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
+   *       //  {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
+   *       // }
+   *       // or
+   *       // {@link $compile#-link- link}: function postLink( ... ) { ... }
+   *     };
+   *     return directiveDefinitionObject;
+   *   });
+   * ```
+   *
+   * 

+   * **Note:** Any unspecified options will use the default value. You can see the default values below.
+   * 

+   *
+   * Therefore the above can be simplified as:
+   *
+   * ```js
+   *   var myModule = angular.module(...);
+   *
+   *   myModule.directive('directiveName', function factory(injectables) {
+   *     var directiveDefinitionObject = {
+   *       link: function postLink(scope, iElement, iAttrs) { ... }
+   *     };
+   *     return directiveDefinitionObject;
+   *     // or
+   *     // return function postLink(scope, iElement, iAttrs) { ... }
+   *   });
+   * ```
+   *
+   * ### Life-cycle hooks
+   * Directive controllers can provide the following methods that are called by AngularJS at points in the life-cycle of the
+   * directive:
+   * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
+   *   had their bindings initialized (and before the pre & post linking functions for the directives on
+   *   this element). This is a good place to put initialization code for your controller.
+   * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
+   *   `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
+   *   object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a
+   *   component such as cloning the bound value to prevent accidental mutation of the outer value. Note that this will
+   *   also be called when your bindings are initialized.
+   * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on
+   *   changes. Any actions that you wish to take in response to the changes that you detect must be
+   *   invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook
+   *   could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not
+   *   be detected by AngularJS's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;
+   *   if detecting changes, you must store the previous value(s) for comparison to the current values.
+   * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing
+   *   external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in
+   *   the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent
+   *   components will have their `$onDestroy()` hook called before child components.
+   * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link
+   *   function this hook can be used to set up DOM event handlers and do direct DOM manipulation.
+   *   Note that child elements that contain `templateUrl` directives will not have been compiled and linked since
+   *   they are waiting for their template to load asynchronously and their own compilation and linking has been
+   *   suspended until that occurs.
+   *
+   * #### Comparison with life-cycle hooks in the new Angular
+   * The new Angular also uses life-cycle hooks for its components. While the AngularJS life-cycle hooks are similar there are
+   * some differences that you should be aware of, especially when it comes to moving your code from AngularJS to Angular:
+   *
+   * * AngularJS hooks are prefixed with `$`, such as `$onInit`. Angular hooks are prefixed with `ng`, such as `ngOnInit`.
+   * * AngularJS hooks can be defined on the controller prototype or added to the controller inside its constructor.
+   *   In Angular you can only define hooks on the prototype of the Component class.
+   * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in AngularJS than you would to
+   *   `ngDoCheck` in Angular.
+   * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be
+   *   propagated throughout the application.
+   *   Angular does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an
+   *   error or do nothing depending upon the state of `enableProdMode()`.
+   *
+   * #### Life-cycle hook examples
+   *
+   * This example shows how you can check for mutations to a Date object even though the identity of the object
+   * has not changed.
+   *
+   * 
+   *   
+   *     angular.module('do-check-module', [])
+   *       .component('app', {
+   *         template:
+   *           'Month: ' +
+   *           'Date: {{ $ctrl.date }}' +
+   *           '',
+   *         controller: function() {
+   *           this.date = new Date();
+   *           this.month = this.date.getMonth();
+   *           this.updateDate = function() {
+   *             this.date.setMonth(this.month);
+   *           };
+   *         }
+   *       })
+   *       .component('test', {
+   *         bindings: { date: '<' },
+   *         template:
+   *           '
{{ $ctrl.log | json }}
',
+   *         controller: function() {
+   *           var previousValue;
+   *           this.log = [];
+   *           this.$doCheck = function() {
+   *             var currentValue = this.date && this.date.valueOf();
+   *             if (previousValue !== currentValue) {
+   *               this.log.push('doCheck: date mutated: ' + this.date);
+   *               previousValue = currentValue;
+   *             }
+   *           };
+   *         }
+   *       });
+   *   
+   *   
+   *     
+   *   
+   * 
+   *
+   * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the
+   * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large
+   * arrays or objects can have a negative impact on your application performance)
+   *
+   * 
+   *   
+   *     

+   *       
+   *       
+   *       
{{ items }}

+   *       
+   *     

+   *   
+   *   
+   *      angular.module('do-check-module', [])
+   *        .component('test', {
+   *          bindings: { items: '<' },
+   *          template:
+   *            '
{{ $ctrl.log | json }}
',
+   *          controller: function() {
+   *            this.log = [];
+   *
+   *            this.$doCheck = function() {
+   *              if (this.items_ref !== this.items) {
+   *                this.log.push('doCheck: items changed');
+   *                this.items_ref = this.items;
+   *              }
+   *              if (!angular.equals(this.items_clone, this.items)) {
+   *                this.log.push('doCheck: items mutated');
+   *                this.items_clone = angular.copy(this.items);
+   *              }
+   *            };
+   *          }
+   *        });
+   *   
+   * 
+   *
+   *
+   * ### Directive Definition Object
+   *
+   * The directive definition object provides instructions to the {@link ng.$compile
+   * compiler}. The attributes are:
+   *
+   * #### `multiElement`
+   * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between
+   * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
+   * together as the directive elements. It is recommended that this feature be used on directives
+   * which are not strictly behavioral (such as {@link ngClick}), and which
+   * do not manipulate or replace child nodes (such as {@link ngInclude}).
+   *
+   * #### `priority`
+   * When there are multiple directives defined on a single DOM element, sometimes it
+   * is necessary to specify the order in which the directives are applied. The `priority` is used
+   * to sort the directives before their `compile` functions get called. Priority is defined as a
+   * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
+   * are also run in priority order, but post-link functions are run in reverse order. The order
+   * of directives with the same priority is undefined. The default priority is `0`.
+   *
+   * #### `terminal`
+   * If set to true then the current `priority` will be the last set of directives
+   * which will execute (any directives at the current priority will still execute
+   * as the order of execution on same `priority` is undefined). Note that expressions
+   * and other directives used in the directive's template will also be excluded from execution.
+   *
+   * #### `scope`
+   * The scope property can be `false`, `true`, or an object:
+   *
+   * * **`false` (default):** No scope will be created for the directive. The directive will use its
+   * parent's scope.
+   *
+   * * **`true`:** A new child scope that prototypically inherits from its parent will be created for
+   * the directive's element. If multiple directives on the same element request a new scope,
+   * only one new scope is created.
+   *
+   * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's template.
+   * The 'isolate' scope differs from normal scope in that it does not prototypically
+   * inherit from its parent scope. This is useful when creating reusable components, which should not
+   * accidentally read or modify data in the parent scope. Note that an isolate scope
+   * directive without a `template` or `templateUrl` will not apply the isolate scope
+   * to its children elements.
+   *
+   * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
+   * directive's element. These local properties are useful for aliasing values for templates. The keys in
+   * the object hash map to the name of the property on the isolate scope; the values define how the property
+   * is bound to the parent scope, via matching attributes on the directive's element:
+   *
+   * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
+   *   always a string since DOM attributes are strings. If no `attr` name is specified then the
+   *   attribute name is assumed to be the same as the local name. Given `` and the isolate scope definition `scope: { localName:'@myAttr' }`,
+   *   the directive's scope property `localName` will reflect the interpolated value of `hello
+   *   {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's
+   *   scope. The `name` is read from the parent scope (not the directive's scope).
+   *
+   * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression
+   *   passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.
+   *   If no `attr` name is specified then the attribute name is assumed to be the same as the local
+   *   name. Given `` and the isolate scope definition `scope: {
+   *   localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the
+   *   value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in
+   *   `localModel` and vice versa. If the binding expression is non-assignable, or if the attribute
+   *   isn't  optional and doesn't exist, an exception
+   *   ({@link error/$compile/nonassign `$compile:nonassign`}) will be thrown upon discovering changes
+   *   to the local value, since it will be impossible to sync them back to the parent scope.
+   *
+   *   By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
+   *   method is used for tracking changes, and the equality check is based on object identity.
+   *   However, if an object literal or an array literal is passed as the binding expression, the
+   *   equality check is done by value (using the {@link angular.equals} function). It's also possible
+   *   to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection
+   *   `$watchCollection`}: use `=*` or `=*attr`
+   *
+    * * `<` or `` and directive definition of
+   *   `scope: { localModel:'` and the isolate scope definition `scope: {
+   *   localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
+   *   the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
+   *   via an expression to the parent scope. This can be done by passing a map of local variable names
+   *   and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
+   *   then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
+   *
+   * All 4 kinds of bindings (`@`, `=`, `<`, and `&`) can be made optional by adding `?` to the expression.
+   * The marker must come after the mode and before the attribute name.
+   * See the {@link error/$compile/iscp Invalid Isolate Scope Definition error} for definition examples.
+   * This is useful to refine the interface directives provide.
+   * One subtle difference between optional and non-optional happens **when the binding attribute is not
+   * set**:
+   * - the binding is optional: the property will not be defined
+   * - the binding is not optional: the property is defined
+   *
+   * ```js
+   *app.directive('testDir', function() {
+      return {
+        scope: {
+          notoptional: '=',
+          optional: '=?',
+        },
+        bindToController: true,
+        controller: function() {
+          this.$onInit = function() {
+            console.log(this.hasOwnProperty('notoptional')) // true
+            console.log(this.hasOwnProperty('optional')) // false
+          }
+        }
+      }
+    })
+   *```
+   *
+   *
+   * ##### Combining directives with different scope defintions
+   *
+   * In general it's possible to apply more than one directive to one element, but there might be limitations
+   * depending on the type of scope required by the directives. The following points will help explain these limitations.
+   * For simplicity only two directives are taken into account, but it is also applicable for several directives:
+   *
+   * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
+   * * **child scope** + **no scope** =>  Both directives will share one single child scope
+   * * **child scope** + **child scope** =>  Both directives will share one single child scope
+   * * **isolated scope** + **no scope** =>  The isolated directive will use it's own created isolated scope. The other directive will use
+   * its parent's scope
+   * * **isolated scope** + **child scope** =>  **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
+   * be applied to the same element.
+   * * **isolated scope** + **isolated scope**  =>  **Won't work!** Only one scope can be related to one element. Therefore these directives
+   * cannot be applied to the same element.
+   *
+   *
+   * #### `bindToController`
+   * This property is used to bind scope properties directly to the controller. It can be either
+   * `true` or an object hash with the same format as the `scope` property.
+   *
+   * When an isolate scope is used for a directive (see above), `bindToController: true` will
+   * allow a component to have its properties bound to the controller, rather than to scope.
+   *
+   * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
+   * properties. You can access these bindings once they have been initialized by providing a controller method called
+   * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
+   * initialized.
+   *
+   * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.
+   * This will set up the scope bindings to the controller directly. Note that `scope` can still be used
+   * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate
+   * scope (useful for component directives).
+   *
+   * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.
+   *
+   *
+   * #### `controller`
+   * Controller constructor function. The controller is instantiated before the
+   * pre-linking phase and can be accessed by other directives (see
+   * `require` attribute). This allows the directives to communicate with each other and augment
+   * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
+   *
+   * * `$scope` - Current scope associated with the element
+   * * `$element` - Current element
+   * * `$attrs` - Current attributes object for the element
+   * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
+   *   `function([scope], cloneLinkingFn, futureParentElement, slotName)`:
+   *    * `scope`: (optional) override the scope.
+   *    * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.
+   *    * `futureParentElement` (optional):
+   *        * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
+   *        * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
+   *        * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
+   *          and when the `cloneLinkingFn` is passed,
+   *          as those elements need to created and cloned in a special way when they are defined outside their
+   *          usual containers (e.g. like ``).
+   *        * See also the `directive.templateNamespace` property.
+   *    * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)
+   *      then the default transclusion is provided.
+   *    The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns
+   *    `true` if the specified slot contains content (i.e. one or more DOM nodes).
+   *
+   * #### `require`
+   * Require another directive and inject its controller as the fourth argument to the linking function. The
+   * `require` property can be a string, an array or an object:
+   * * a **string** containing the name of the directive to pass to the linking function
+   * * an **array** containing the names of directives to pass to the linking function. The argument passed to the
+   * linking function will be an array of controllers in the same order as the names in the `require` property
+   * * an **object** whose property values are the names of the directives to pass to the linking function. The argument
+   * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding
+   * controllers.
+   *
+   * If the `require` property is an object and `bindToController` is truthy, then the required controllers are
+   * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers
+   * have been constructed but before `$onInit` is called.
+   * If the name of the required controller is the same as the local name (the key), the name can be
+   * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.
+   * See the {@link $compileProvider#component} helper for an example of how this can be used.
+   * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is
+   * raised (unless no link function is specified and the required controllers are not being bound to the directive
+   * controller, in which case error checking is skipped). The name can be prefixed with:
+   *
+   * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
+   * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
+   * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
+   * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
+   * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
+   *   `null` to the `link` fn if not found.
+   * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
+   *   `null` to the `link` fn if not found.
+   *
+   *
+   * #### `controllerAs`
+   * Identifier name for a reference to the controller in the directive's scope.
+   * This allows the controller to be referenced from the directive template. This is especially
+   * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
+   * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
+   * `controllerAs` reference might overwrite a property that already exists on the parent scope.
+   *
+   *
+   * #### `restrict`
+   * String of subset of `EACM` which restricts the directive to a specific directive
+   * declaration style. If omitted, the defaults (elements and attributes) are used.
+   *
+   * * `E` - Element name (default): ``
+   * * `A` - Attribute (default): `
`
+   * * `C` - Class: `
`
+   * * `M` - Comment: ``
+   *
+   *
+   * #### `templateNamespace`
+   * String representing the document type used by the markup in the template.
+   * AngularJS needs this information as those elements need to be created and cloned
+   * in a special way when they are defined outside their usual containers like `` and ``.
+   *
+   * * `html` - All root nodes in the template are HTML. Root nodes may also be
+   *   top-level elements such as `` or ``.
+   * * `svg` - The root nodes in the template are SVG elements (excluding ``).
+   * * `math` - The root nodes in the template are MathML elements (excluding ``).
+   *
+   * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
+   *
+   * #### `template`
+   * HTML markup that may:
+   * * Replace the contents of the directive's element (default).
+   * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
+   * * Wrap the contents of the directive's element (if `transclude` is true).
+   *
+   * Value may be:
+   *
+   * * A string. For example `
{{delete_str}}
`.
+   * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
+   *   function api below) and returns a string value.
+   *
+   *
+   * #### `templateUrl`
+   * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
+   *
+   * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
+   * for later when the template has been resolved.  In the meantime it will continue to compile and link
+   * sibling and parent elements as though this element had not contained any directives.
+   *
+   * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
+   * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
+   * case when only one deeply nested directive has `templateUrl`.
+   *
+   * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
+   *
+   * You can specify `templateUrl` as a string representing the URL or as a function which takes two
+   * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
+   * a string value representing the url.  In either case, the template URL is passed through {@link
+   * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
+   *
+   *
+   * #### `replace`
+   * 

+   * **Note:** `replace` is deprecated in AngularJS and has been removed in the new Angular (v2+).
+   * 

+   *
+   * Specifies what the template should replace. Defaults to `false`.
+   *
+   * * `true` - the template will replace the directive's element.
+   * * `false` - the template will replace the contents of the directive's element.
+   *
+   * The replacement process migrates all of the attributes / classes from the old element to the new
+   * one. See the {@link guide/directive#template-expanding-directive
+   * Directives Guide} for an example.
+   *
+   * There are very few scenarios where element replacement is required for the application function,
+   * the main one being reusable custom components that are used within SVG contexts
+   * (because SVG doesn't work with custom elements in the DOM tree).
+   *
+   * #### `transclude`
+   * Extract the contents of the element where the directive appears and make it available to the directive.
+   * The contents are compiled and provided to the directive as a **transclusion function**. See the
+   * {@link $compile#transclusion Transclusion} section below.
+   *
+   *
+   * #### `compile`
+   *
+   * ```js
+   *   function compile(tElement, tAttrs, transclude) { ... }
+   * ```
+   *
+   * The compile function deals with transforming the template DOM. Since most directives do not do
+   * template transformation, it is not used often. The compile function takes the following arguments:
+   *
+   *   * `tElement` - template element - The element where the directive has been declared. It is
+   *     safe to do template transformation on the element and child elements only.
+   *
+   *   * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
+   *     between all directive compile functions.
+   *
+   *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
+   *
+   * 

+   * **Note:** The template instance and the link instance may be different objects if the template has
+   * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
+   * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
+   * should be done in a linking function rather than in a compile function.
+   * 

+  
+   * 

+   * **Note:** The compile function cannot handle directives that recursively use themselves in their
+   * own templates or compile functions. Compiling these directives results in an infinite loop and
+   * stack overflow errors.
+   *
+   * This can be avoided by manually using $compile in the postLink function to imperatively compile
+   * a directive's template instead of relying on automatic template compilation via `template` or
+   * `templateUrl` declaration or manual compilation inside the compile function.
+   * 

+   *
+   * 

+   * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
+   *   e.g. does not know about the right outer scope. Please use the transclude function that is passed
+   *   to the link function instead.
+   * 

+  
+   * A compile function can have a return value which can be either a function or an object.
+   *
+   * * returning a (post-link) function - is equivalent to registering the linking function via the
+   *   `link` property of the config object when the compile function is empty.
+   *
+   * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
+   *   control when a linking function should be called during the linking phase. See info about
+   *   pre-linking and post-linking functions below.
+   *
+   *
+   * #### `link`
+   * This property is used only if the `compile` property is not defined.
+   *
+   * ```js
+   *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
+   * ```
+   *
+   * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
+   * executed after the template has been cloned. This is where most of the directive logic will be
+   * put.
+   *
+   *   * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
+   *     directive for registering {@link ng.$rootScope.Scope#$watch watches}.
+   *
+   *   * `iElement` - instance element - The element where the directive is to be used. It is safe to
+   *     manipulate the children of the element only in `postLink` function since the children have
+   *     already been linked.
+   *
+   *   * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
+   *     between all directive linking functions.
+   *
+   *   * `controller` - the directive's required controller instance(s) - Instances are shared
+   *     among all directives, which allows the directives to use the controllers as a communication
+   *     channel. The exact value depends on the directive's `require` property:
+   *       * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
+   *       * `string`: the controller instance
+   *       * `array`: array of controller instances
+   *
+   *     If a required controller cannot be found, and it is optional, the instance is `null`,
+   *     otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
+   *
+   *     Note that you can also require the directive's own controller - it will be made available like
+   *     any other controller.
+   *
+   *   * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
+   *     This is the same as the `$transclude` parameter of directive controllers,
+   *     see {@link ng.$compile#-controller- the controller section for details}.
+   *     `function([scope], cloneLinkingFn, futureParentElement)`.
+   *
+   * #### Pre-linking function
+   *
+   * Executed before the child elements are linked. Not safe to do DOM transformation since the
+   * compiler linking function will fail to locate the correct elements for linking.
+   *
+   * #### Post-linking function
+   *
+   * Executed after the child elements are linked.
+   *
+   * Note that child elements that contain `templateUrl` directives will not have been compiled
+   * and linked since they are waiting for their template to load asynchronously and their own
+   * compilation and linking has been suspended until that occurs.
+   *
+   * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
+   * for their async templates to be resolved.
+   *
+   *
+   * ### Transclusion
+   *
+   * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
+   * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
+   * scope from where they were taken.
+   *
+   * Transclusion is used (often with {@link ngTransclude}) to insert the
+   * original contents of a directive's element into a specified place in the template of the directive.
+   * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
+   * content has access to the properties on the scope from which it was taken, even if the directive
+   * has isolated scope.
+   * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
+   *
+   * This makes it possible for the widget to have private state for its template, while the transcluded
+   * content has access to its originating scope.
+   *
+   * 

+   * **Note:** When testing an element transclude directive you must not place the directive at the root of the
+   * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
+   * Testing Transclusion Directives}.
+   * 

+   *
+   * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the
+   * directive's element, the entire element or multiple parts of the element contents:
+   *
+   * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
+   * * `'element'` - transclude the whole of the directive's element including any directives on this
+   *   element that defined at a lower priority than this directive. When used, the `template`
+   *   property is ignored.
+   * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template.
+   *
+   * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.
+   *
+   * This object is a map where the keys are the name of the slot to fill and the value is an element selector
+   * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)
+   * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).
+   *
+   * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}
+   *
+   * If the element selector is prefixed with a `?` then that slot is optional.
+   *
+   * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `` elements to
+   * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.
+   *
+   * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements
+   * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call
+   * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and
+   * injectable into the directive's controller.
+   *
+   *
+   * #### Transclusion Functions
+   *
+   * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
+   * function** to the directive's `link` function and `controller`. This transclusion function is a special
+   * **linking function** that will return the compiled contents linked to a new transclusion scope.
+   *
+   * 

+   * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
+   * ngTransclude will deal with it for us.
+   * 

+   *
+   * If you want to manually control the insertion and removal of the transcluded content in your directive
+   * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
+   * object that contains the compiled DOM, which is linked to the correct transclusion scope.
+   *
+   * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
+   * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
+   * content and the `scope` is the newly created transclusion scope, which the clone will be linked to.
+   *
+   * 

+   * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function
+   * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
+   * 

+   *
+   * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
+   * attach function**:
+   *
+   * ```js
+   * var transcludedContent, transclusionScope;
+   *
+   * $transclude(function(clone, scope) {
+   *   element.append(clone);
+   *   transcludedContent = clone;
+   *   transclusionScope = scope;
+   * });
+   * ```
+   *
+   * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
+   * associated transclusion scope:
+   *
+   * ```js
+   * transcludedContent.remove();
+   * transclusionScope.$destroy();
+   * ```
+   *
+   * 

+   * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
+   * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
+   * then you are also responsible for calling `$destroy` on the transclusion scope.
+   * 

+   *
+   * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
+   * automatically destroy their transcluded clones as necessary so you do not need to worry about this if
+   * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
+   *
+   *
+   * #### Transclusion Scopes
+   *
+   * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
+   * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
+   * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
+   * was taken.
+   *
+   * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
+   * like this:
+   *
+   * ```html
+   * 

+   *   

+   *     

+   *     

+   *   

+   * 

+   * ```
+   *
+   * The `$parent` scope hierarchy will look like this:
+   *
+     ```
+     - $rootScope
+       - isolate
+         - transclusion
+     ```
+   *
+   * but the scopes will inherit prototypically from different scopes to their `$parent`.
+   *
+     ```
+     - $rootScope
+       - transclusion
+     - isolate
+     ```
+   *
+   *
+   * ### Attributes
+   *
+   * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
+   * `link()` or `compile()` functions. It has a variety of uses.
+   *
+   * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:
+   *   'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access
+   *   to the attributes.
+   *
+   * * *Directive inter-communication:* All directives share the same instance of the attributes
+   *   object which allows the directives to use the attributes object as inter directive
+   *   communication.
+   *
+   * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
+   *   allowing other directives to read the interpolated value.
+   *
+   * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
+   *   that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
+   *   the only way to easily get the actual value because during the linking phase the interpolation
+   *   hasn't been evaluated yet and so the value is at this time set to `undefined`.
+   *
+   * ```js
+   * function linkingFn(scope, elm, attrs, ctrl) {
+   *   // get the attribute value
+   *   console.log(attrs.ngModel);
+   *
+   *   // change the attribute
+   *   attrs.$set('ngModel', 'new value');
+   *
+   *   // observe changes to interpolated attribute
+   *   attrs.$observe('ngModel', function(value) {
+   *     console.log('ngModel has changed value to ' + value);
+   *   });
+   * }
+   * ```
+   *
+   * ## Example
+   *
+   * 

+   * **Note**: Typically directives are registered with `module.directive`. The example below is
+   * to illustrate how `$compile` works.
+   * 

+   *
+   
+     
+      
+      

+         

+         

+        

+      

+     
+     
+       it('should auto compile', function() {
+         var textarea = $('textarea');
+         var output = $('div[compile]');
+         // The initial state reads 'Hello AngularJS'.
+         expect(output.getText()).toBe('Hello AngularJS');
+         textarea.clear();
+         textarea.sendKeys('{{name}}!');
+         expect(output.getText()).toBe('AngularJS!');
+       });
+     
+   
+  
+   *
+   *
+   * @param {string|DOMElement} element Element or HTML string to compile into a template function.
+   * @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives - DEPRECATED.
+   *
+   * 

+   * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it
+   *   e.g. will not use the right outer scope. Please pass the transclude function as a
+   *   `parentBoundTranscludeFn` to the link function instead.
+   *

+   *
+   *  * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
+   *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
+   *  `template` and call the `cloneAttachFn` function allowing the caller to attach the
+   *  cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
+   *  called as: 
 `cloneAttachFn(clonedElement, scope)` where:
+   *
+   *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
+   *      * `scope` - is the current scope with which the linking function is working with.
+   *
+   *  * `options` - An optional object hash with linking options. If `options` is provided, then the following
+   *  keys may be used to control linking behavior:
+   *
+   *      * `parentBoundTranscludeFn` - the transclude function made available to
+   *        directives; if given, it will be passed through to the link functions of
+   *        directives found in `element` during compilation.
+   *      * `transcludeControllers` - an object hash with keys that map controller names
+   *        to a hash with the key `instance`, which maps to the controller instance;
+   *        if given, it will make the controllers available to directives on the compileNode:
+   *        ```
+   *        {
+   *          parent: {
+   *            instance: parentControllerInstance
+   *          }
+   *        }
+   *        ```
+   *      * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add
+   *        the cloned elements; only needed for transcludes that are allowed to contain non html
+   *        elements (e.g. SVG elements). See also the directive.controller property.
+   *
+   * Calling the linking function returns the element of the template. It is either the original
+   * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
+   *
+   * After linking the view is not updated until after a call to $digest which typically is done by
+   * AngularJS automatically.
+   *
+   * If you need access to the bound view, there are two ways to do it:
+   *
+   * - If you are not asking the linking function to clone the template, create the DOM element(s)
+   *   before you send them to the compiler and keep this reference around.
+   *   ```js
+   *     var element = $compile('
{{total}}
')(scope);
+   *   ```
+   *
+   * - if on the other hand, you need the element to be cloned, the view reference from the original
+   *   example would not point to the clone, but rather to the original template that was cloned. In
+   *   this case, you can access the clone via the cloneAttachFn:
+   *   ```js
+   *     var templateElement = angular.element('
{{total}}
'),
+   *         scope = ....;
+   *
+   *     var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
+   *       //attach the clone to DOM document at the right place
+   *     });
+   *
+   *     //now we have reference to the cloned DOM via `clonedElement`
+   *   ```
+   *

+   * {@link guide/compiler AngularJS HTML Compiler} section of the Developer Guide.

+   * ### Double Compilation
+   *
+     Double compilation occurs when an already compiled part of the DOM gets
+     compiled again. This is an undesired effect and can lead to misbehaving directives, performance issues,
+     and memory leaks. Refer to the Compiler Guide {@link guide/compiler#double-compilation-and-how-to-avoid-it
+     section on double compilation} for an in-depth explanation and ways to avoid it.
+  
+   * @knownIssue
+  
+     ### Issues with `replace: true`
+   *
+   * 

+   *   **Note**: {@link $compile#-replace- `replace: true`} is deprecated and not recommended to use,
+   *   mainly due to the issues listed here. It has been completely removed in the new Angular.
+   * 

+   *
+   * #### Attribute values are not merged
+   *
+   * When a `replace` directive encounters the same attribute on the original and the replace node,
+   * it will simply deduplicate the attribute and join the values with a space or with a `;` in case of
+   * the `style` attribute.
+   * ```html
+   * Original Node: 
+   * Replace Template: 
+   * Result: 
+   * ```
    *
-   * In complex applications it's possible that dependencies between `$onChanges` hooks and bindings will result
-   * in several iterations of calls to these hooks. However if an application needs more than the default 10
-   * iterations to stabilize then you should investigate what is causing the model to continuously change during
-   * the `$onChanges` hook execution.
+   * That means attributes that contain AngularJS expressions will not be merged correctly, e.g.
+   * {@link ngShow} or {@link ngClass} will cause a {@link $parse} error:
    *
-   * Increasing the TTL could have performance implications, so you should not change it without proper justification.
+   * ```html
+   * Original Node: 
+   * Replace Template: 
+   * Result: 
+   * ```
+   *
+   * See issue [#5695](https://github.com/angular/angular.js/issues/5695).
+   *
+   * #### Directives are not deduplicated before compilation
+   *
+   * When the original node and the replace template declare the same directive(s), they will be
+   * {@link guide/compiler#double-compilation-and-how-to-avoid-it compiled twice} because the compiler
+   * does not deduplicate them. In many cases, this is not noticable, but e.g. {@link ngModel} will
+   * attach `$formatters` and `$parsers` twice.
+   *
+   * See issue [#2573](https://github.com/angular/angular.js/issues/2573).
+   *
+   * #### `transclude: element` in the replace template root can have unexpected effects
+   *
+   * When the replace template has a directive at the root node that uses
+   * {@link $compile#-transclude- `transclude: element`}, e.g.
+   * {@link ngIf} or {@link ngRepeat}, the DOM structure or scope inheritance can be incorrect.
+   * See the following issues:
+   *
+   * - Incorrect scope on replaced element:
+   * [#9837](https://github.com/angular/angular.js/issues/9837)
+   * - Different DOM between `template` and `templateUrl`:
+   * [#10612](https://github.com/angular/angular.js/issues/14326)
    *
-   * @param {number} limit The number of `$onChanges` hook iterations.
-   * @returns {number|object} the current limit (or `this` if called as a setter for chaining)

    * @description
+   * The `ngProp` directive binds an expression to a DOM element property.
+   * `ngProp` allows writing to arbitrary properties by including
+   * the property name in the attribute, e.g. `ng-prop-value="'my value'"` binds 'my value' to
+   * the `value` property.
+   *
+   * Usually, it's not necessary to write to properties in AngularJS, as the built-in directives
+   * handle the most common use cases (instead of the above example, you would use {@link ngValue}).
+   *
+   * However, [custom elements](https://developer.mozilla.org/docs/Web/Web_Components/Using_custom_elements)
+   * often use custom properties to hold data, and `ngProp` can be used to provide input to these
+   * custom elements.
+   *
+   * ## Binding to camelCase properties
+   *
+   * Since HTML attributes are case-insensitive, camelCase properties like `innerHTML` must be escaped.
+   * AngularJS uses the underscore (_) in front of a character to indicate that it is uppercase, so
+   * `innerHTML`  must be written as `ng-prop-inner_h_t_m_l="expression"` (Note that this is just an
+   * example, and for binding HTML {@link ngBindHtml} should be used.
+   *
+   * ## Security
+   *
+   * Binding expressions to arbitrary properties poses a security risk, as  properties like `innerHTML`
+   * can insert potentially dangerous HTML into the application, e.g. script tags that execute
+   * malicious code.
+   * For this reason, `ngProp` applies Strict Contextual Escaping with the {@link ng.$sce $sce service}.
+   * This means vulnerable properties require their content to be "trusted", based on the
+   * context of the property. For example, the `innerHTML` is in the `HTML` context, and the
+   * `iframe.src` property is in the `RESOURCE_URL` context, which requires that values written to
+   * this property are trusted as a `RESOURCE_URL`.
+   *
+   * This can be set explicitly by calling $sce.trustAs(type, value) on the value that is
+   * trusted before passing it to the `ng-prop-*` directive. There are exist shorthand methods for
+   * each context type in the form of {@link ng.$sce#trustAsResourceUrl $sce.trustAsResourceUrl()} et al.
+   *
+   * In some cases you can also rely upon automatic sanitization of untrusted values - see below.
+   *
+   * Based on the context, other options may exist to mark a value as trusted / configure the behavior
+   * of {@link ng.$sce}. For example, to restrict the `RESOURCE_URL` context to specific origins, use
+   * the {@link $sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist()}
+   * and {@link $sceDelegateProvider#resourceUrlBlacklist resourceUrlBlacklist()}.
+   *
+   * {@link ng.$sce#what-trusted-context-types-are-supported- Find out more about the different context types}.
+   *
+   * ### HTML Sanitization
    *
-   * It indicates to the compiler
-   * whether or not directives on comments should be compiled.
-   * Defaults to `true`.
+   * By default, `$sce` will throw an error if it detects untrusted HTML content, and will not bind the
+   * content.
+   * However, if you include the {@link ngSanitize ngSanitize module}, it will try to sanitize the
+   * potentially dangerous HTML, e.g. strip non-whitelisted tags and attributes when binding to
+   * `innerHTML`.
    *
-   * Calling this function with false disables the compilation of directives
-   * on comments for the whole application.
-   * This results in a compilation performance gain,
-   * as the compiler doesn't have to check comments when looking for directives.
-   * This should however only be used if you are sure that no comment directives are used in
-   * the application (including any 3rd party directives).
+   * @example
+   * ### Binding to different contexts
+   *
+   * 
+   *   
+   *     angular.module('exampleNgProp', [])
+   *       .component('main', {
+   *         templateUrl: 'main.html',
+   *         controller: function($sce) {
+   *           this.safeContent = 'Safe content';
+   *           this.unsafeContent = '';
+   *           this.trustedUnsafeContent = $sce.trustAsHtml(this.unsafeContent);
+   *         }
+   *       });
+   *   
+   *   
+   *     

+   *       

+   *         Binding to a property without security context:
+   *         

+   *         innerText (safeContent)
+   *       

+   *
+   *       

+   *         "Safe" content that requires a security context will throw because the contents could potentially be dangerous ...
+   *         

+   *         innerHTML (safeContent)
+   *       

+   *
+   *       

+   *         ... so that actually dangerous content cannot be executed:
+   *         

+   *         innerHTML (unsafeContent)
+   *       

+   *
+   *       

+   *         ... but unsafe Content that has been trusted explicitly works - only do this if you are 100% sure!
+   *         

+   *         innerHTML (trustedUnsafeContent)
+   *       

+   *     

+   *   
+   *   
+   *     

+   *   
+   *   
+   *     .prop-unit {
+   *       margin-bottom: 10px;
+   *     }
+   *
+   *     .prop-binding {
+   *       min-height: 30px;
+   *       border: 1px solid blue;
+   *     }
+   *
+   *     .prop-note {
+   *       font-family: Monospace;
+   *     }
+   *   
+   * 
+   *
+   *
+   * @example
+   * ### Binding to innerHTML with ngSanitize
+   *
+   * 
+   *   
+   *     angular.module('exampleNgProp', ['ngSanitize'])
+   *       .component('main', {
+   *         templateUrl: 'main.html',
+   *         controller: function($sce) {
+   *           this.safeContent = 'Safe content';
+   *           this.unsafeContent = '';
+   *           this.trustedUnsafeContent = $sce.trustAsHtml(this.unsafeContent);
+   *         }
+   *       });
+   *   
+   *   
+   *     

+   *       

+   *         "Safe" content will be sanitized ...
+   *         

+   *         innerHTML (safeContent)
+   *       

+   *
+   *       

+   *         ... as will dangerous content:
+   *         

+   *         innerHTML (unsafeContent)
+   *       

+   *
+   *       

+   *         ... and content that has been trusted explicitly works the same as without ngSanitize:
+   *         

+   *         innerHTML (trustedUnsafeContent)
+   *       

+   *     

+   *   
+   *   
+   *

+   * The `ngOn` directive adds an event listener to a DOM element via

-   * It indicates to the compiler

-   * Defaults to `true`.
+   * AngularJS provides specific directives for many events, such as {@link ngClick}, so in most

+   *       mouseover: {{$ctrl.mouseoverCount}}
+   *
+   *

+     * Register a **component definition** with the compiler. This is a shorthand for registering a special
+     * type of directive, which represents a self-contained UI component in your application. Such components
+     * are always isolated (i.e. `scope: {}`) and are always restricted to elements (i.e. `restrict: 'E'`).
+     *
+     * Component definitions are very simple and do not require as much configuration as defining general
+     * directives. Component definitions usually consist only of a template and a controller backing it.
+     *
+     * In order to make the definition easier, components enforce best practices like use of `controllerAs`,
+     * `bindToController`. They always have **isolate scope** and are restricted to elements.
+     *
+     * Here are a few examples of how you would usually define components:
+     *
+     * ```js
+     *   var myMod = angular.module(...);
+     *   myMod.component('myComp', {
+     *     template: '
My name is {{$ctrl.name}}
',
+     *     controller: function() {
+     *       this.name = 'shahar';
+     *     }
+     *   });
+     *
+     *   myMod.component('myComp', {
+     *     template: '
My name is {{$ctrl.name}}
',
+     *     bindings: {name: '@'}
+     *   });
+     *
+     *   myMod.component('myComp', {
+     *     templateUrl: 'views/my-comp.html',
+     *     controller: 'MyCtrl',
+     *     controllerAs: 'ctrl',
+     *     bindings: {name: '@'}
+     *   });

- * @ngdoc service
- * @name $exceptionHandler
- * @requires ng.$log
- * @this
- *
- * @description
- * Any uncaught exception in AngularJS expressions is delegated to this service.
- * The default implementation simply delegates to `$log.error` which logs it into
- * the browser console.
- *
- * In unit tests, if `angular-mocks.js` is loaded, this service is overridden by
- * {@link ngMock.$exceptionHandler mock $exceptionHandler} which aids in testing.
- *
- * ## Example:
- *
- * The example below will overwrite the default `$exceptionHandler` in order to (a) log uncaught
- * errors to the backend for later inspection by the developers and (b) to use `$log.warn()` instead
- * of `$log.error()`.
- *
- * ```js
- *   angular.
- *     module('exceptionOverwrite', []).
- *     factory('$exceptionHandler', ['$log', 'logErrorsToBackend', function($log, logErrorsToBackend) {
- *       return function myExceptionHandler(exception, cause) {
- *         logErrorsToBackend(exception, cause);
- *         $log.warn(exception, cause);
- *       };
- *     }]);
- * ```
- *
- * 

- * Note, that code executed in event-listeners (even those registered using jqLite's `on`/`bind`
- * methods) does not delegate exceptions to the {@link ng.$exceptionHandler $exceptionHandler}
- * (unless executed during a digest).
- *
- * If you wish, you can manually delegate exceptions, e.g.
- * `try { ... } catch(e) { $exceptionHandler(e); }`
- *
- * @param {Error} exception Exception associated with the error.
- * @param {string=} cause Optional information about the context in which
- *       the error was thrown.

    *
    * @description
+   * Any uncaught exception in AngularJS expressions is delegated to this service.
+   * The default implementation simply delegates to `$log.error` which logs it into
+   * the browser console.
+   *
+   * In unit tests, if `angular-mocks.js` is loaded, this service is overridden by
+   * {@link ngMock.$exceptionHandler mock $exceptionHandler} which aids in testing.
    *
-   * Alternative {@link $http `$http`} params serializer that follows
-   * jQuery's [`param()`](http://api.jquery.com/jquery.param/) method logic.
-   * The serializer will also sort the params alphabetically.
+   * ## Example:
    *
-   * To use it for serializing `$http` request parameters, set it as the `paramSerializer` property:
+   * The example below will overwrite the default `$exceptionHandler` in order to (a) log uncaught
+   * errors to the backend for later inspection by the developers and (b) to use `$log.warn()` instead
+   * of `$log.error()`.
    *
    * ```js
-   * $http({
-   *   url: myUrl,
-   *   method: 'GET',
-   *   params: myParams,
-   *   paramSerializer: '$httpParamSerializerJQLike'
-   * });
+   *   angular.
+   *     module('exceptionOverwrite', []).
+   *     factory('$exceptionHandler', ['$log', 'logErrorsToBackend', function($log, logErrorsToBackend) {
+   *       return function myExceptionHandler(exception, cause) {
+   *         logErrorsToBackend(exception, cause);
+   *         $log.warn(exception, cause);
+   *       };
+   *     }]);
    * ```
    *
-   * It is also possible to set it as the default `paramSerializer` in the
-   * {@link $httpProvider#defaults `$httpProvider`}.
-   *
-   * Additionally, you can inject the serializer and use it explicitly, for example to serialize
-   * form data for submission:
+   * 

+   * Note, that code executed in event-listeners (even those registered using jqLite's `on`/`bind`
+   * methods) does not delegate exceptions to the {@link ng.$exceptionHandler $exceptionHandler}
+   * (unless executed during a digest).
    *
-   * ```js
-   * .controller(function($http, $httpParamSerializerJQLike) {
-   *   //...
-   *
-   *   $http({
-   *     url: myUrl,
-   *     method: 'POST',
-   *     data: $httpParamSerializerJQLike(myData),
-   *     headers: {
-   *       'Content-Type': 'application/x-www-form-urlencoded'
-   *     }
-   *   });
+   * If you wish, you can manually delegate exceptions, e.g.
+   * `try { ... } catch(e) { $exceptionHandler(e); }`
    *
-   * });
-   * ```
+   * @param {Error} exception Exception associated with the error.
+   * @param {string=} cause Optional information about the context in which
+   *       the error was thrown.

      * @description
-     * The `$http` service is a core AngularJS service that facilitates communication with the remote
-     * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
-     * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
-     *
-     * For unit testing applications that use `$http` service, see
-     * {@link ngMock.$httpBackend $httpBackend mock}.
-     *
-     * For a higher level of abstraction, please check out the {@link ngResource.$resource
-     * $resource} service.
-     *
-     * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
-     * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
-     * it is important to familiarize yourself with these APIs and the guarantees they provide.
-     *
-     *
-     * ## General usage
-     * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —
-     * that is used to generate an HTTP request and returns  a {@link ng.$q promise} that is
-     * resolved (request success) or rejected (request failure) with a
-     * {@link ng.$http#$http-returns response} object.
-     *
-     * ```js
-     *   // Simple GET request example:
-     *   $http({
-     *     method: 'GET',
-     *     url: '/someUrl'
-     *   }).then(function successCallback(response) {
-     *       // this callback will be called asynchronously
-     *       // when the response is available
-     *     }, function errorCallback(response) {
-     *       // called asynchronously if an error occurs
-     *       // or server returns response with an error status.
-     *     });
-     * ```
      *
+     * Object containing default values for all {@link ng.$http $http} requests.
      *
-     * ## Shortcut methods
+     * - **`defaults.cache`** - {boolean|Object} - A boolean value or object created with
+     * {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of HTTP responses
+     * by default. See {@link $http#caching $http Caching} for more information.
      *
-     * Shortcut methods are also available. All shortcut methods require passing in the URL, and
-     * request data must be passed in for POST/PUT requests. An optional config can be passed as the
-     * last argument.
+     * - **`defaults.headers`** - {Object} - Default headers for all $http requests.
+     * Refer to {@link ng.$http#setting-http-headers $http} for documentation on
+     * setting default headers.
+     *     - **`defaults.headers.common`**
+     *     - **`defaults.headers.post`**
+     *     - **`defaults.headers.put`**
+     *     - **`defaults.headers.patch`**
      *
-     * ```js
-     *   $http.get('/someUrl', config).then(successCallback, errorCallback);
-     *   $http.post('/someUrl', data, config).then(successCallback, errorCallback);
-     * ```
+     * - **`defaults.jsonpCallbackParam`** - `{string}` - the name of the query parameter that passes the name of the
+     * callback in a JSONP request. The value of this parameter will be replaced with the expression generated by the

-     * ## Writing Unit Tests that use $http
-     * When unit testing (using {@link ngMock ngMock}), it is necessary to call
-     * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
-     * request using trained responses.
+     * - **`defaults.transformResponse`** -
+     * `{Array|function(data, headersGetter, status)}` -
+     * An array of functions (or a single function) which are applied to the response data. By default,
+     * this is an array which applies one response transformation function that does two things:
      *
-     * ```
-     * $httpBackend.expectGET(...);
-     * $http.get(...);
-     * $httpBackend.flush();
-     * ```
+     *  - If XSRF prefix is detected, strip it
+     *    (see {@link ng.$http#security-considerations Security Considerations in the $http docs}).
+     *  - If the `Content-Type` is `application/json` or the response looks like JSON,
+     *    deserialize it using a JSON parser.

-     * ## Setting HTTP Headers
+     * - **`defaults.xsrfCookieName`** - {string} - Name of cookie containing the XSRF token.
+     * Defaults value is `'XSRF-TOKEN'`.

-     * The $http service will automatically add certain HTTP headers to all requests. These defaults

+     * Array containing URLs whose origins are trusted to receive the XSRF token. See the
+     * {@link ng.$http#security-considerations Security Considerations} sections for more details on
+     * XSRF.
      *
-     * Both requests and responses can be transformed using transformation functions: `transformRequest`
-     * and `transformResponse`. These properties can be a single function that returns
-     * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
-     * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
+     * **Note:** An "origin" consists of the [URI scheme](https://en.wikipedia.org/wiki/URI_scheme),
+     * the [hostname](https://en.wikipedia.org/wiki/Hostname) and the
+     * [port number](https://en.wikipedia.org/wiki/Port_(computer_networking). For `http:` and

+     * Examples: `http://example.com`, `https://api.example.com:9876`
      *
      * 

-     * **Note:** AngularJS does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.
-     * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).
-     * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest
-     * function will be reflected on the scope and in any templates where the object is data-bound.
-     * To prevent this, transform functions should have no side-effects.
-     * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.
+     *   It is not possible to whitelist specific URLs/paths. The `path`, `query` and `fragment` parts
+     *   of a URL will be ignored. For example, `https://foo.com/path/bar?query=baz#fragment` will be
+     *   treated as `https://foo.com`, meaning that **all** requests to URLs starting with
+     *   `https://foo.com/` will include the XSRF token.
      * 

      *
-     * ### Default Transformations
-     *
-     * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
-     * `defaults.transformResponse` properties. If a request does not provide its own transformations
-     * then these will be applied.
-     *
-     * You can augment or replace the default transformations by modifying these properties by adding to or
-     * replacing the array.
-     *
-     * AngularJS provides the following default transformations:
-     *
-     * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`) is
-     * an array with one function that does the following:
-     *
-     * - If the `data` property of the request configuration object contains an object, serialize it
-     *   into JSON format.
-     *
-     * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`) is
-     * an array with one function that does the following:
-     *
-     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
-     *  - If the `Content-Type` is `application/json` or the response looks like JSON,
-   *      deserialize it using a JSON parser.
-     *
-     *
-     * ### Overriding the Default Transformations Per Request
-     *
-     * If you wish to override the request/response transformations only for a single request then provide
-     * `transformRequest` and/or `transformResponse` properties on the configuration object passed
-     * into `$http`.
-     *
-     * Note that if you provide these properties on the config object the default transformations will be
-     * overwritten. If you wish to augment the default transformations then you must include them in your
-     * local transformation array.
-     *
-     * The following code demonstrates adding a new response transformation to be run after the default response
-     * transformations have been run.
-     *
-     * ```js
-     * function appendTransform(defaults, transform) {
-     *
-     *   // We can't guarantee that the default transformation is an array
-     *   defaults = angular.isArray(defaults) ? defaults : [defaults];
-     *
-     *   // Append the new transformation to the defaults
-     *   return defaults.concat(transform);
-     * }
-     *
-     * $http({
-     *   url: '...',
-     *   method: 'GET',
-     *   transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
-     *     return doTransform(value);
-     *   })
-     * });
-     * ```
-     *
-     *
-     * ## Caching
-     *
-     * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must
-     * set the config.cache value or the default cache value to TRUE or to a cache object (created
-     * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes
-     * precedence over the default cache value.
-     *
-     * In order to:
-     *   * cache all responses - set the default cache value to TRUE or to a cache object
-     *   * cache a specific response - set config.cache value to TRUE or to a cache object
-     *
-     * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,
-     * then the default `$cacheFactory("$http")` object is used.
-     *
-     * The default cache value can be set by updating the
-     * {@link ng.$http#defaults `$http.defaults.cache`} property or the
-     * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.
-     *
-     * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using
-     * the relevant cache object. The next time the same request is made, the response is returned
-     * from the cache without sending a request to the server.
-     *
-     * Take note that:
-     *
-     *   * Only GET and JSONP requests are cached.
-     *   * The cache key is the request URL including search parameters; headers are not considered.
-     *   * Cached responses are returned asynchronously, in the same way as responses from the server.
-     *   * If multiple identical requests are made using the same cache, which is not yet populated,
-     *     one request will be made to the server and remaining requests will return the same response.
-     *   * A cache-control header on the response does not affect if or how responses are cached.
-     *
-     *
-     * ## Interceptors
-     *
-     * Before you start creating interceptors, be sure to understand the
-     * {@link ng.$q $q and deferred/promise APIs}.
-     *
-     * For purposes of global error handling, authentication, or any kind of synchronous or
-     * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
-     * able to intercept requests before they are handed to the server and
-     * responses before they are handed over to the application code that
-     * initiated these requests. The interceptors leverage the {@link ng.$q
-     * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
-     *
-     * The interceptors are service factories that are registered with the `$httpProvider` by
-     * adding them to the `$httpProvider.interceptors` array. The factory is called and
-     * injected with dependencies (if specified) and returns the interceptor.
-     *
-     * There are two kinds of interceptors (and two kinds of rejection interceptors):
-     *
-     *   * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
-     *     modify the `config` object or create a new one. The function needs to return the `config`
-     *     object directly, or a promise containing the `config` or a new `config` object.
-     *   * `requestError`: interceptor gets called when a previous interceptor threw an error or
-     *     resolved with a rejection.
-     *   * `response`: interceptors get called with http `response` object. The function is free to
-     *     modify the `response` object or create a new one. The function needs to return the `response`
-     *     object directly, or as a promise containing the `response` or a new `response` object.
-     *   * `responseError`: interceptor gets called when a previous interceptor threw an error or
-     *     resolved with a rejection.
-     *
-     *
-     * ```js
-     *   // register the interceptor as a service
-     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
-     *     return {
-     *       // optional method
-     *       'request': function(config) {
-     *         // do something on success
-     *         return config;
-     *       },
-     *
-     *       // optional method
-     *      'requestError': function(rejection) {
-     *         // do something on error
-     *         if (canRecover(rejection)) {
-     *           return responseOrNewPromise
-     *         }
-     *         return $q.reject(rejection);
-     *       },
-     *
-     *
-     *
-     *       // optional method
-     *       'response': function(response) {
-     *         // do something on success
-     *         return response;
-     *       },
-     *
-     *       // optional method
-     *      'responseError': function(rejection) {
-     *         // do something on error
-     *         if (canRecover(rejection)) {
-     *           return responseOrNewPromise
-     *         }
-     *         return $q.reject(rejection);
-     *       }
-     *     };
-     *   });
-     *
-     *   $httpProvider.interceptors.push('myHttpInterceptor');
-     *
-     *
-     *   // alternatively, register the interceptor via an anonymous factory
-     *   $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
-     *     return {
-     *      'request': function(config) {
-     *          // same as above
-     *       },
-     *
-     *       'response': function(response) {
-     *          // same as above
-     *       }
-     *     };
-     *   });
-     * ```
-     *
-     * ## Security Considerations
-     *
-     * When designing web applications, consider security threats from:
-     *
-     * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
-     * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
-     *
-     * Both server and the client must cooperate in order to eliminate these threats. AngularJS comes
-     * pre-configured with strategies that address these issues, but for this to work backend server
-     * cooperation is required.
-     *
-     * ### JSON Vulnerability Protection
-     *
-     * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
-     * allows third party website to turn your JSON resource URL into
-     * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
-     * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
-     * AngularJS will automatically strip the prefix before processing it as JSON.
+     * @example
      *
-     * For example if your server needs to return:
      * ```js
-     * ['one','two']
-     * ```
+     * // App served from `https://example.com/`.
+     * angular.
+     *   module('xsrfWhitelistedOriginsExample', []).
+     *   config(['$httpProvider', function($httpProvider) {
+     *     $httpProvider.xsrfWhitelistedOrigins.push('https://api.example.com');
+     *   }]).
+     *   run(['$http', function($http) {
+     *     // The XSRF token will be sent.
+     *     $http.get('https://api.example.com/preferences').then(...);
      *
-     * which is vulnerable to attack, your server can return:
-     * ```js
-     * )]}',
-     * ['one','two']
+     *     // The XSRF token will NOT be sent.
+     *     $http.get('https://stats.example.com/activity').then(...);
+     *   }]);
      * ```
-     *
-     * AngularJS will strip the prefix, before processing the JSON.
-     *
-     *
-     * ### Cross Site Request Forgery (XSRF) Protection
-     *
-     * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by
-     * which the attacker can trick an authenticated user into unknowingly executing actions on your
-     * website. AngularJS provides a mechanism to counter XSRF. When performing XHR requests, the
-     * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP
-     * header (by default `X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read
-     * the cookie, your server can be assured that the XHR came from JavaScript running on your
-     * domain.
-     *
-     * To take advantage of this, your server needs to set a token in a JavaScript readable session
-     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
-     * server can verify that the cookie matches the `X-XSRF-TOKEN` HTTP header, and therefore be
-     * sure that only JavaScript running on your domain could have sent the request. The token must
-     * be unique for each user and must be verifiable by the server (to prevent the JavaScript from
-     * making up its own tokens). We recommend that the token is a digest of your site's
-     * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))
-     * for added security.
-     *
-     * The header will — by default — **not** be set for cross-domain requests. This
-     * prevents unauthorized servers (e.g. malicious or compromised 3rd-party APIs) from gaining
-     * access to your users' XSRF tokens and exposing them to Cross Site Request Forgery. If you
-     * want to, you can whitelist additional origins to also receive the XSRF token, by adding them
-     * to {@link ng.$httpProvider#xsrfWhitelistedOrigins xsrfWhitelistedOrigins}. This might be
-     * useful, for example, if your application, served from `example.com`, needs to access your API
-     * at `api.example.com`.
-     * See {@link ng.$httpProvider#xsrfWhitelistedOrigins $httpProvider.xsrfWhitelistedOrigins} for
-     * more details.
-     *
-     * 

-     *   **Warning**

-     *   Only whitelist origins that you have control over and make sure you understand the
-     *   implications of doing so.
-     * 

-     *
-     * The name of the cookie and the header can be specified using the `xsrfCookieName` and
-     * `xsrfHeaderName` properties of either `$httpProvider.defaults` at config-time,
-     * `$http.defaults` at run-time, or the per-request config object.
-     *
-     * In order to prevent collisions in environments where multiple AngularJS apps share the
-     * same domain or subdomain, we recommend that each application uses a unique cookie name.
-     *
-     *
-     * @param {object} config Object describing the request to be made and how it should be
-     *    processed. The object has following properties:
-     *
-     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
-     *    - **url** – `{string|TrustedObject}` – Absolute or relative URL of the resource that is being requested;
-     *      or an object created by a call to `$sce.trustAsResourceUrl(url)`.
-     *    - **params** – `{Object.}` – Map of strings or objects which will be serialized
-     *      with the `paramSerializer` and appended as GET parameters.
-     *    - **data** – `{string|Object}` – Data to be sent as the request message data.
-     *    - **headers** – `{Object}` – Map of strings or functions which return strings representing
-     *      HTTP headers to send to the server. If the return value of a function is null, the
-     *      header will not be sent. Functions accept a config object as an argument.
-     *    - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.
-     *      To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.
-     *      The handler will be called in the context of a `$apply` block.
-     *    - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload
-     *      object. To bind events to the XMLHttpRequest object, use `eventHandlers`.
-     *      The handler will be called in the context of a `$apply` block.
-     *    - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
-     *    - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
-     *    - **transformRequest** –
-     *      `{function(data, headersGetter)|Array.}` –
-     *      transform function or an array of such functions. The transform function takes the http
-     *      request body and headers and returns its transformed (typically serialized) version.
-     *      See {@link ng.$http#overriding-the-default-transformations-per-request
-     *      Overriding the Default Transformations}
-     *    - **transformResponse** –
-     *      `{function(data, headersGetter, status)|Array.}` –
-     *      transform function or an array of such functions. The transform function takes the http
-     *      response body, headers and status and returns its transformed (typically deserialized) version.
-     *      See {@link ng.$http#overriding-the-default-transformations-per-request
-     *      Overriding the Default Transformations}
-     *    - **paramSerializer** - `{string|function(Object):string}` - A function used to
-     *      prepare the string representation of request parameters (specified as an object).
-     *      If specified as string, it is interpreted as function registered with the
-     *      {@link $injector $injector}, which means you can create your own serializer
-     *      by registering it as a {@link auto.$provide#service service}.
-     *      The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
-     *      alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
-     *    - **cache** – `{boolean|Object}` – A boolean value or object created with
-     *      {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
-     *      See {@link $http#caching $http Caching} for more information.
-     *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
-     *      that should abort the request when resolved.
-     *
-     *      A numerical timeout or a promise returned from {@link ng.$timeout $timeout}, will set
-     *      the `xhrStatus` in the {@link $http#$http-returns response} to "timeout", and any other
-     *      resolved promise will set it to "abort", following standard XMLHttpRequest behavior.
-     *
-     *    - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
-     *      XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
-     *      for more information.
-     *    - **responseType** - `{string}` - see
-     *      [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
-     *
-     * @returns {HttpPromise} A {@link ng.$q `Promise}` that will be resolved (request success)
-     *   or rejected (request failure) with a response object.
-     *
-     *   The response object has these properties:
-     *
-     *   - **data** – `{string|Object}` – The response body transformed with
-     *     the transform functions.
-     *   - **status** – `{number}` – HTTP status code of the response.
-     *   - **headers** – `{function([headerName])}` – Header getter function.
-     *   - **config** – `{Object}` – The configuration object that was used
-     *     to generate the request.
-     *   - **statusText** – `{string}` – HTTP status text of the response.
-     *   - **xhrStatus** – `{string}` – Status of the XMLHttpRequest
-     *     (`complete`, `error`, `timeout` or `abort`).
-     *
-     *
-     *   A response status code between 200 and 299 is considered a success status
-     *   and will result in the success callback being called. Any response status
-     *   code outside of that range is considered an error status and will result
-     *   in the error callback being called.
-     *   Also, status codes less than -1 are normalized to zero. -1 usually means
-     *   the request was aborted, e.g. using a `config.timeout`. More information
-     *   about the status might be available in the `xhrStatus` property.
-     *
-     *   Note that if the response is a redirect, XMLHttpRequest will transparently
-     *   follow it, meaning that the outcome (success or error) will be determined
-     *   by the final response status code.
-     *
-     *
-     * @property {Array.} pendingRequests Array of config objects for currently pending
-     *   requests. This is primarily meant to be used for debugging purposes.
-     *
-     *
-     * @example

+       *
+       * @description
+       * The `$http` service is a core AngularJS service that facilitates communication with the remote
+       * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
+       * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
+       *
+       * For unit testing applications that use `$http` service, see
+       * {@link ngMock.$httpBackend $httpBackend mock}.
+       *
+       * For a higher level of abstraction, please check out the {@link ngResource.$resource
+       * $resource} service.
+       *
+       * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
+       * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
+       * it is important to familiarize yourself with these APIs and the guarantees they provide.
+       *
+       *
+       * ## General usage
+       * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —
+       * that is used to generate an HTTP request and returns  a {@link ng.$q promise} that is
+       * resolved (request success) or rejected (request failure) with a
+       * {@link ng.$http#$http-returns response} object.
+       *
+       * ```js
+       *   // Simple GET request example:
+       *   $http({
+       *     method: 'GET',
+       *     url: '/someUrl'
+       *   }).then(function successCallback(response) {
+       *       // this callback will be called asynchronously
+       *       // when the response is available
+       *     }, function errorCallback(response) {
+       *       // called asynchronously if an error occurs
+       *       // or server returns response with an error status.
+       *     });
+       * ```
+       *
+       *
+       * ## Shortcut methods
+       *
+       * Shortcut methods are also available. All shortcut methods require passing in the URL, and
+       * request data must be passed in for POST/PUT requests. An optional config can be passed as the
+       * last argument.
+       *
+       * ```js
+       *   $http.get('/someUrl', config).then(successCallback, errorCallback);
+       *   $http.post('/someUrl', data, config).then(successCallback, errorCallback);
+       * ```
+       *
+       * Complete list of shortcut methods:
+       *
+       * - {@link ng.$http#get $http.get}
+       * - {@link ng.$http#head $http.head}
+       * - {@link ng.$http#post $http.post}
+       * - {@link ng.$http#put $http.put}
+       * - {@link ng.$http#delete $http.delete}
+       * - {@link ng.$http#jsonp $http.jsonp}
+       * - {@link ng.$http#patch $http.patch}
+       *
+       *
+       * ## Writing Unit Tests that use $http
+       * When unit testing (using {@link ngMock ngMock}), it is necessary to call
+       * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
+       * request using trained responses.
+       *
+       * ```
+       * $httpBackend.expectGET(...);
+       * $http.get(...);
+       * $httpBackend.flush();
+       * ```
+       *
+       * ## Setting HTTP Headers
+       *
+       * The $http service will automatically add certain HTTP headers to all requests. These defaults
+       * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
+       * object, which currently contains this default configuration:
+       *
+       * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
+       *   - Accept: application/json, text/plain, \*/\*
+       * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
+       *   - `Content-Type: application/json`
+       * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
+       *   - `Content-Type: application/json`
+       *
+       * To add or overwrite these defaults, simply add or remove a property from these configuration
+       * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
+       * with the lowercased HTTP method name as the key, e.g.
+       * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
+       *
+       * The defaults can also be set at runtime via the `$http.defaults` object in the same
+       * fashion. For example:
+       *
+       * ```
+       * module.run(function($http) {
+       *   $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';
+       * });
+       * ```
+       *
+       * In addition, you can supply a `headers` property in the config object passed when
+       * calling `$http(config)`, which overrides the defaults without changing them globally.
+       *
+       * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
+       * Use the `headers` property, setting the desired header to `undefined`. For example:
+       *
+       * ```js
+       * var req = {
+       *  method: 'POST',
+       *  url: 'http://example.com',
+       *  headers: {
+       *    'Content-Type': undefined
+       *  },
+       *  data: { test: 'test' }
+       * }
+       *
+       * $http(req).then(function(){...}, function(){...});
+       * ```
+       *
+       * ## Transforming Requests and Responses
+       *
+       * Both requests and responses can be transformed using transformation functions: `transformRequest`
+       * and `transformResponse`. These properties can be a single function that returns
+       * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
+       * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
+       *
+       * 

+       * **Note:** AngularJS does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.
+       * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).
+       * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest
+       * function will be reflected on the scope and in any templates where the object is data-bound.
+       * To prevent this, transform functions should have no side-effects.
+       * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.
+       * 

+       *
+       * ### Default Transformations
+       *
+       * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
+       * `defaults.transformResponse` properties. If a request does not provide its own transformations
+       * then these will be applied.
+       *
+       * You can augment or replace the default transformations by modifying these properties by adding to or
+       * replacing the array.
+       *
+       * AngularJS provides the following default transformations:
+       *
+       * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`) is
+       * an array with one function that does the following:
+       *
+       * - If the `data` property of the request configuration object contains an object, serialize it
+       *   into JSON format.
+       *
+       * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`) is
+       * an array with one function that does the following:
+       *
+       *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
+       *  - If the `Content-Type` is `application/json` or the response looks like JSON,
+      *      deserialize it using a JSON parser.
+       *
+       *
+       * ### Overriding the Default Transformations Per Request
+       *
+       * If you wish to override the request/response transformations only for a single request then provide
+       * `transformRequest` and/or `transformResponse` properties on the configuration object passed
+       * into `$http`.
+       *
+       * Note that if you provide these properties on the config object the default transformations will be
+       * overwritten. If you wish to augment the default transformations then you must include them in your
+       * local transformation array.
+       *
+       * The following code demonstrates adding a new response transformation to be run after the default response
+       * transformations have been run.
+       *
+       * ```js
+       * function appendTransform(defaults, transform) {
+       *
+       *   // We can't guarantee that the default transformation is an array
+       *   defaults = angular.isArray(defaults) ? defaults : [defaults];
+       *
+       *   // Append the new transformation to the defaults
+       *   return defaults.concat(transform);
+       * }
+       *
+       * $http({
+       *   url: '...',
+       *   method: 'GET',
+       *   transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
+       *     return doTransform(value);
+       *   })
+       * });
+       * ```
+       *
+       *
+       * ## Caching
+       *
+       * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must
+       * set the config.cache value or the default cache value to TRUE or to a cache object (created
+       * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes
+       * precedence over the default cache value.
+       *
+       * In order to:
+       *   * cache all responses - set the default cache value to TRUE or to a cache object
+       *   * cache a specific response - set config.cache value to TRUE or to a cache object
+       *
+       * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,
+       * then the default `$cacheFactory("$http")` object is used.
+       *
+       * The default cache value can be set by updating the
+       * {@link ng.$http#defaults `$http.defaults.cache`} property or the
+       * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.
+       *
+       * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using
+       * the relevant cache object. The next time the same request is made, the response is returned
+       * from the cache without sending a request to the server.
+       *
+       * Take note that:
+       *
+       *   * Only GET and JSONP requests are cached.
+       *   * The cache key is the request URL including search parameters; headers are not considered.
+       *   * Cached responses are returned asynchronously, in the same way as responses from the server.
+       *   * If multiple identical requests are made using the same cache, which is not yet populated,
+       *     one request will be made to the server and remaining requests will return the same response.
+       *   * A cache-control header on the response does not affect if or how responses are cached.
+       *
+       *
+       * ## Interceptors
+       *
+       * Before you start creating interceptors, be sure to understand the
+       * {@link ng.$q $q and deferred/promise APIs}.
+       *
+       * For purposes of global error handling, authentication, or any kind of synchronous or
+       * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
+       * able to intercept requests before they are handed to the server and
+       * responses before they are handed over to the application code that
+       * initiated these requests. The interceptors leverage the {@link ng.$q
+       * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
+       *
+       * The interceptors are service factories that are registered with the `$httpProvider` by
+       * adding them to the `$httpProvider.interceptors` array. The factory is called and
+       * injected with dependencies (if specified) and returns the interceptor.
+       *
+       * There are two kinds of interceptors (and two kinds of rejection interceptors):
+       *
+       *   * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
+       *     modify the `config` object or create a new one. The function needs to return the `config`
+       *     object directly, or a promise containing the `config` or a new `config` object.
+       *   * `requestError`: interceptor gets called when a previous interceptor threw an error or
+       *     resolved with a rejection.
+       *   * `response`: interceptors get called with http `response` object. The function is free to
+       *     modify the `response` object or create a new one. The function needs to return the `response`
+       *     object directly, or as a promise containing the `response` or a new `response` object.
+       *   * `responseError`: interceptor gets called when a previous interceptor threw an error or
+       *     resolved with a rejection.
+       *
+       *
+       * ```js
+       *   // register the interceptor as a service
+       *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
+       *     return {
+       *       // optional method
+       *       'request': function(config) {
+       *         // do something on success
+       *         return config;
+       *       },
+       *
+       *       // optional method
+       *      'requestError': function(rejection) {
+       *         // do something on error
+       *         if (canRecover(rejection)) {
+       *           return responseOrNewPromise
+       *         }
+       *         return $q.reject(rejection);
+       *       },
+       *
+       *
+       *
+       *       // optional method
+       *       'response': function(response) {
+       *         // do something on success
+       *         return response;

+       * ## Security Considerations
+       *
+       * When designing web applications, consider security threats from:
+       *
+       * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
+       * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
+       *
+       * Both server and the client must cooperate in order to eliminate these threats. AngularJS comes
+       * pre-configured with strategies that address these issues, but for this to work backend server
+       * cooperation is required.
+       *
+       * ### JSON Vulnerability Protection
+       *
+       * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
+       * allows third party website to turn your JSON resource URL into
+       * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
+       * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
+       * AngularJS will automatically strip the prefix before processing it as JSON.
+       *
+       * For example if your server needs to return:
+       * ```js
+       * ['one','two']
+       * ```
+       *
+       * which is vulnerable to attack, your server can return:
+       * ```js
+       * )]}',
+       * ['one','two']
+       * ```
+       *
+       * AngularJS will strip the prefix, before processing the JSON.
+       *
+       *
+       * ### Cross Site Request Forgery (XSRF) Protection
+       *
+       * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by
+       * which the attacker can trick an authenticated user into unknowingly executing actions on your
+       * website. AngularJS provides a mechanism to counter XSRF. When performing XHR requests, the
+       * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP
+       * header (by default `X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read
+       * the cookie, your server can be assured that the XHR came from JavaScript running on your
+       * domain.
+       *
+       * To take advantage of this, your server needs to set a token in a JavaScript readable session
+       * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
+       * server can verify that the cookie matches the `X-XSRF-TOKEN` HTTP header, and therefore be
+       * sure that only JavaScript running on your domain could have sent the request. The token must
+       * be unique for each user and must be verifiable by the server (to prevent the JavaScript from
+       * making up its own tokens). We recommend that the token is a digest of your site's
+       * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))
+       * for added security.
+       *
+       * The header will — by default — **not** be set for cross-domain requests. This
+       * prevents unauthorized servers (e.g. malicious or compromised 3rd-party APIs) from gaining
+       * access to your users' XSRF tokens and exposing them to Cross Site Request Forgery. If you
+       * want to, you can whitelist additional origins to also receive the XSRF token, by adding them
+       * to {@link ng.$httpProvider#xsrfWhitelistedOrigins xsrfWhitelistedOrigins}. This might be
+       * useful, for example, if your application, served from `example.com`, needs to access your API
+       * at `api.example.com`.
+       * See {@link ng.$httpProvider#xsrfWhitelistedOrigins $httpProvider.xsrfWhitelistedOrigins} for
+       * more details.
+       *
+       * 

+       *   **Warning**

+       *   Only whitelist origins that you have control over and make sure you understand the
+       *   implications of doing so.
+       * 

+       *
+       * The name of the cookie and the header can be specified using the `xsrfCookieName` and
+       * `xsrfHeaderName` properties of either `$httpProvider.defaults` at config-time,
+       * `$http.defaults` at run-time, or the per-request config object.
+       *
+       * In order to prevent collisions in environments where multiple AngularJS apps share the
+       * same domain or subdomain, we recommend that each application uses a unique cookie name.
+       *
+       *
+       * @param {object} config Object describing the request to be made and how it should be
+       *    processed. The object has following properties:
+       *
+       *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
+       *    - **url** – `{string|TrustedObject}` – Absolute or relative URL of the resource that is being requested;
+       *      or an object created by a call to `$sce.trustAsResourceUrl(url)`.
+       *    - **params** – `{Object.}` – Map of strings or objects which will be serialized
+       *      with the `paramSerializer` and appended as GET parameters.
+       *    - **data** – `{string|Object}` – Data to be sent as the request message data.
+       *    - **headers** – `{Object}` – Map of strings or functions which return strings representing
+       *      HTTP headers to send to the server. If the return value of a function is null, the
+       *      header will not be sent. Functions accept a config object as an argument.
+       *    - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.
+       *      To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.
+       *      The handler will be called in the context of a `$apply` block.
+       *    - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload
+       *      object. To bind events to the XMLHttpRequest object, use `eventHandlers`.
+       *      The handler will be called in the context of a `$apply` block.
+       *    - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
+       *    - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
+       *    - **transformRequest** –
+       *      `{function(data, headersGetter)|Array.}` –
+       *      transform function or an array of such functions. The transform function takes the http
+       *      request body and headers and returns its transformed (typically serialized) version.
+       *      See {@link ng.$http#overriding-the-default-transformations-per-request
+       *      Overriding the Default Transformations}
+       *    - **transformResponse** –
+       *      `{function(data, headersGetter, status)|Array.}` –
+       *      transform function or an array of such functions. The transform function takes the http
+       *      response body, headers and status and returns its transformed (typically deserialized) version.
+       *      See {@link ng.$http#overriding-the-default-transformations-per-request
+       *      Overriding the Default Transformations}
+       *    - **paramSerializer** - `{string|function(Object):string}` - A function used to
+       *      prepare the string representation of request parameters (specified as an object).
+       *      If specified as string, it is interpreted as function registered with the
+       *      {@link $injector $injector}, which means you can create your own serializer
+       *      by registering it as a {@link auto.$provide#service service}.
+       *      The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
+       *      alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
+       *    - **cache** – `{boolean|Object}` – A boolean value or object created with
+       *      {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
+       *      See {@link $http#caching $http Caching} for more information.
+       *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
+       *      that should abort the request when resolved.
+       *
+       *      A numerical timeout or a promise returned from {@link ng.$timeout $timeout}, will set
+       *      the `xhrStatus` in the {@link $http#$http-returns response} to "timeout", and any other
+       *      resolved promise will set it to "abort", following standard XMLHttpRequest behavior.
+       *
+       *    - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
+       *      XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
+       *      for more information.
+       *    - **responseType** - `{string}` - see
+       *      [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
+       *
+       * @returns {HttpPromise} A {@link ng.$q `Promise}` that will be resolved (request success)
+       *   or rejected (request failure) with a response object.
+       *
+       *   The response object has these properties:
+       *
+       *   - **data** – `{string|Object}` – The response body transformed with
+       *     the transform functions.
+       *   - **status** – `{number}` – HTTP status code of the response.
+       *   - **headers** – `{function([headerName])}` – Header getter function.
+       *   - **config** – `{Object}` – The configuration object that was used
+       *     to generate the request.
+       *   - **statusText** – `{string}` – HTTP status text of the response.
+       *   - **xhrStatus** – `{string}` – Status of the XMLHttpRequest
+       *     (`complete`, `error`, `timeout` or `abort`).
+       *
+       *
+       *   A response status code between 200 and 299 is considered a success status
+       *   and will result in the success callback being called. Any response status
+       *   code outside of that range is considered an error status and will result
+       *   in the error callback being called.
+       *   Also, status codes less than -1 are normalized to zero. -1 usually means
+       *   the request was aborted, e.g. using a `config.timeout`. More information
+       *   about the status might be available in the `xhrStatus` property.
+       *
+       *   Note that if the response is a redirect, XMLHttpRequest will transparently
+       *   follow it, meaning that the outcome (success or error) will be determined
+       *   by the final response status code.
+       *
+       *
+       * @property {Array.} pendingRequests Array of config objects for currently pending
+       *   requests. This is primarily meant to be used for debugging purposes.

+       *
+       * JSONP requests must specify a callback to be used in the response from the server. This callback
+       * is passed as a query parameter in the request. You must specify the name of this parameter by
+       * setting the `jsonpCallbackParam` property on the request config object.
+       *
+       * ```
+       * $http.jsonp('some/trusted/url', {jsonpCallbackParam: 'callback'})

+       * You can no longer use the `JSON_CALLBACK` string as a placeholder for specifying where the callback

-     * @ngdoc service
-     * @name $interpolate
-     * @kind function
-     *
-     * @requires $parse
-     * @requires $sce
-     *
-     * @description
-     *
-     * Compiles a string with markup into an interpolation function. This service is used by the
-     * HTML {@link ng.$compile $compile} service for data binding. See
-     * {@link ng.$interpolateProvider $interpolateProvider} for configuring the
-     * interpolation markup.
-     *
-     *
-     * ```js
-     *   var $interpolate = ...; // injected
-     *   var exp = $interpolate('Hello {{name | uppercase}}!');
-     *   expect(exp({name:'AngularJS'})).toEqual('Hello ANGULARJS!');
-     * ```
-     *
-     * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
-     * `true`, the interpolation function will return `undefined` unless all embedded expressions
-     * evaluate to a value other than `undefined`.
-     *
-     * ```js
-     *   var $interpolate = ...; // injected
-     *   var context = {greeting: 'Hello', name: undefined };
-     *
-     *   // default "forgiving" mode
-     *   var exp = $interpolate('{{greeting}} {{name}}!');
-     *   expect(exp(context)).toEqual('Hello !');
-     *
-     *   // "allOrNothing" mode
-     *   exp = $interpolate('{{greeting}} {{name}}!', false, null, true);
-     *   expect(exp(context)).toBeUndefined();
-     *   context.name = 'AngularJS';
-     *   expect(exp(context)).toEqual('Hello AngularJS!');
-     * ```
-     *
-     * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
-     *
-     * #### Escaped Interpolation
-     * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
-     * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
-     * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
-     * or binding.
-     *
-     * This enables web-servers to prevent script injection attacks and defacing attacks, to some
-     * degree, while also enabling code examples to work without relying on the
-     * {@link ng.directive:ngNonBindable ngNonBindable} directive.
-     *
-     * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
-     * replacing angle brackets (<, >) with &lt; and &gt; respectively, and replacing all
-     * interpolation start/end markers with their escaped counterparts.**
-     *
-     * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
-     * output when the $interpolate service processes the text. So, for HTML elements interpolated
-     * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
-     * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
-     * this is typically useful only when user-data is used in rendering a template from the server, or
-     * when otherwise untrusted data is used by a directive.
-     *
-     * 
-     *  
-     *    

-     *      
{{apptitle}}: \{\{ username = "defaced value"; \}\}
-     *        

-     *      
{{username}} attempts to inject code which will deface the
-     *        application, but fails to accomplish their task, because the server has correctly
-     *        escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
-     *        characters.

-     *      
Instead, the result of the attempted script injection is visible, and can be removed
-     *        from the database by an administrator.

-     *    

-     *  
-     * 
-     *
-     * @knownIssue
-     * It is currently not possible for an interpolated expression to contain the interpolation end
-     * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e.
-     * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string.
-     *
-     * @knownIssue
-     * All directives and components must use the standard `{{` `}}` interpolation symbols
-     * in their templates. If you change the application interpolation symbols the {@link $compile}
-     * service will attempt to denormalize the standard symbols to the custom symbols.
-     * The denormalization process is not clever enough to know not to replace instances of the standard
-     * symbols where they would not normally be treated as interpolation symbols. For example in the following
-     * code snippet the closing braces of the literal object will get incorrectly denormalized:
-     *
-     * ```
-     * 

-     * ```

      * @description
-     * AngularJS's wrapper for `window.setInterval`. The `fn` function is executed every `delay`
-     * milliseconds.
-     *
-     * The return value of registering an interval function is a promise. This promise will be
-     * notified upon each tick of the interval, and will be resolved after `count` iterations, or
-     * run indefinitely if `count` is not defined. The value of the notification will be the
-     * number of iterations that have run.
-     * To cancel an interval, call `$interval.cancel(promise)`.
-     *
-     * In tests you can use {@link ngMock.$interval#flush `$interval.flush(millis)`} to
-     * move forward by `millis` milliseconds and trigger any functions scheduled to run in that
-     * time.
-     *
-     * 

-     * **Note**: Intervals created by this service must be explicitly destroyed when you are finished
-     * with them.  In particular they are not automatically destroyed when a controller's scope or a
-     * directive's element are destroyed.
-     * You should take this into consideration and make sure to always cancel the interval at the
-     * appropriate moment.  See the example below for more details on how and when to do this.
-     * 

-     *
-     * @param {function()} fn A function that should be called repeatedly. If no additional arguments
-     *   are passed (see below), the function is called with the current iteration count.
-     * @param {number} delay Number of milliseconds between each function call.
-     * @param {number=} [count=0] Number of times to repeat. If not set, or 0, will repeat
-     *   indefinitely.
-     * @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise
-     *   will invoke `fn` within the {@link ng.$rootScope.Scope#$apply $apply} block.
-     * @param {...*=} Pass additional parameters to the executed function.
-     * @returns {promise} A promise which will be notified on each iteration. It will resolve once all iterations of the interval complete.
-     *
-     * @example
-     * 
-     * 
-     *   
-     *
-     *   

-     *     

-     *

-     *       

-     *       Blood 1 : {{blood_1}}
-     *       Blood 2 : {{blood_2}}
-     *

+       *   var exp = $interpolate('Hello {{name | uppercase}}!');

+       * ```
+       *
+       * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
+       * `true`, the interpolation function will return `undefined` unless all embedded expressions
+       * evaluate to a value other than `undefined`.
+       *
+       * ```js
+       *   var $interpolate = ...; // injected

+       *   expect(exp(context)).toEqual('Hello AngularJS!');
+       * ```
+       *
+       * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
+       *
+       * #### Escaped Interpolation
+       * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
+       * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
+       * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
+       * or binding.
+       *
+       * This enables web-servers to prevent script injection attacks and defacing attacks, to some
+       * degree, while also enabling code examples to work without relying on the
+       * {@link ng.directive:ngNonBindable ngNonBindable} directive.
+       *
+       * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
+       * replacing angle brackets (<, >) with &lt; and &gt; respectively, and replacing all
+       * interpolation start/end markers with their escaped counterparts.**
+       *
+       * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
+       * output when the $interpolate service processes the text. So, for HTML elements interpolated
+       * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
+       * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
+       * this is typically useful only when user-data is used in rendering a template from the server, or
+       * when otherwise untrusted data is used by a directive.
+       *
+       * 
+       *  
+       *    

+       *      
{{apptitle}}: \{\{ username = "defaced value"; \}\}
+       *        

+       *      
{{username}} attempts to inject code which will deface the
+       *        application, but fails to accomplish their task, because the server has correctly
+       *        escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
+       *        characters.

+       *      
Instead, the result of the attempted script injection is visible, and can be removed
+       *        from the database by an administrator.

+       *    

+       *  
+       * 
+       *
+       * @knownIssue
+       * It is currently not possible for an interpolated expression to contain the interpolation end
+       * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e.
+       * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string.
+       *
+       * @knownIssue
+       * All directives and components must use the standard `{{` `}}` interpolation symbols
+       * in their templates. If you change the application interpolation symbols the {@link $compile}
+       * service will attempt to denormalize the standard symbols to the custom symbols.
+       * The denormalization process is not clever enough to know not to replace instances of the standard
+       * symbols where they would not normally be treated as interpolation symbols. For example in the following
+       * code snippet the closing braces of the literal object will get incorrectly denormalized:
+       *
+       * ```
+       * 

+       * ```

-       * in the JSONP response.
+       * AngularJS's wrapper for `window.setInterval`. The `fn` function is executed every `delay`
+       * milliseconds.
+       *
+       * The return value of registering an interval function is a promise. This promise will be
+       * notified upon each tick of the interval, and will be resolved after `count` iterations, or
+       * run indefinitely if `count` is not defined. The value of the notification will be the
+       * number of iterations that have run.
+       * To cancel an interval, call `$interval.cancel(promise)`.
+       *
+       * In tests you can use {@link ngMock.$interval#flush `$interval.flush(millis)`} to
+       * move forward by `millis` milliseconds and trigger any functions scheduled to run in that
+       * time.
+       *
+       * 

+       * **Note**: Intervals created by this service must be explicitly destroyed when you are finished
+       * with them.  In particular they are not automatically destroyed when a controller's scope or a
+       * directive's element are destroyed.
+       * You should take this into consideration and make sure to always cancel the interval at the
+       * appropriate moment.  See the example below for more details on how and when to do this.
+       * 

+       *
+       * @param {function()} fn A function that should be called repeatedly. If no additional arguments
+       *   are passed (see below), the function is called with the current iteration count.
+       * @param {number} delay Number of milliseconds between each function call.
+       * @param {number=} [count=0] Number of times to repeat. If not set, or 0, will repeat
+       *   indefinitely.
+       * @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise
+       *   will invoke `fn` within the {@link ng.$rootScope.Scope#$apply $apply} block.
+       * @param {...*=} Pass additional parameters to the executed function.
+       * @returns {promise} A promise which will be notified on each iteration. It will resolve once all iterations of the interval complete.
+       *
+       * @example
+       * 
+       * 
+       *   
+       *
+       *   

+       *

- * @ngdoc service
- * @name $log
- * @requires $window
- *
- * @description
- * Simple service for logging. Default implementation safely writes the message
- * into the browser's console (if present).
- *
- * The main purpose of this service is to simplify debugging and troubleshooting.
- *
- * To reveal the location of the calls to `$log` in the JavaScript console,
- * you can "blackbox" the AngularJS source in your browser:
- *
- * [Mozilla description of blackboxing](https://developer.mozilla.org/en-US/docs/Tools/Debugger/How_to/Black_box_a_source).
- * [Chrome description of blackboxing](https://developer.chrome.com/devtools/docs/blackboxing).
- *
- * Note: Not all browsers support blackboxing.
- *
- * The default is to log `debug` messages. You can use
- * {@link ng.$logProvider ng.$logProvider#debugEnabled} to change this.
- *
- * @example
-   
-     
-       angular.module('logExample', [])
-         .controller('LogController', ['$scope', '$log', function($scope, $log) {
-           $scope.$log = $log;
-           $scope.message = 'Hello World!';
-         }]);
-     
-     
-       

-

-/**
- * @ngdoc service
- * @name $q
- * @requires $rootScope
- *
- * @description
- * A service that helps you run functions asynchronously, and use their return values (or exceptions)
- * when they are done processing.
- *
- * This is a [Promises/A+](https://promisesaplus.com/)-compliant implementation of promises/deferred
- * objects inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
- *
- * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
- * implementations, and the other which resembles ES6 (ES2015) promises to some degree.
- *
- * ## $q constructor
- *
- * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
- * function as the first argument. This is similar to the native Promise implementation from ES6,
- * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
- *
- * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are
- * available yet.
- *
- * It can be used like so:
- *
- * ```js
- *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
- *   // are available in the current lexical scope (they could have been injected or passed in).
- *
- *   function asyncGreet(name) {
- *     // perform some asynchronous operation, resolve or reject the promise when appropriate.
- *     return $q(function(resolve, reject) {
- *       setTimeout(function() {
- *         if (okToGreet(name)) {
- *           resolve('Hello, ' + name + '!');
- *         } else {
- *           reject('Greeting ' + name + ' is not allowed.');
- *         }
- *       }, 1000);
- *     });
- *   }
- *
- *   var promise = asyncGreet('Robin Hood');
- *   promise.then(function(greeting) {
- *     alert('Success: ' + greeting);
- *   }, function(reason) {
- *     alert('Failed: ' + reason);
- *   });
- * ```
- *
- * Note: progress/notify callbacks are not currently supported via the ES6-style interface.
- *
- * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise.
- *
- * However, the more traditional CommonJS-style usage is still available, and documented below.
- *
- * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
- * interface for interacting with an object that represents the result of an action that is
- * performed asynchronously, and may or may not be finished at any given point in time.
- *
- * From the perspective of dealing with error handling, deferred and promise APIs are to
- * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
- *
- * ```js
- *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
- *   // are available in the current lexical scope (they could have been injected or passed in).
- *
- *   function asyncGreet(name) {
- *     var deferred = $q.defer();
- *
- *     setTimeout(function() {
- *       deferred.notify('About to greet ' + name + '.');
- *
- *       if (okToGreet(name)) {
- *         deferred.resolve('Hello, ' + name + '!');
- *       } else {
- *         deferred.reject('Greeting ' + name + ' is not allowed.');
- *       }
- *     }, 1000);
- *
- *     return deferred.promise;
- *   }
- *
- *   var promise = asyncGreet('Robin Hood');
- *   promise.then(function(greeting) {
- *     alert('Success: ' + greeting);
- *   }, function(reason) {
- *     alert('Failed: ' + reason);
- *   }, function(update) {
- *     alert('Got notification: ' + update);
- *   });
- * ```
- *
- * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
- * comes in the way of guarantees that promise and deferred APIs make, see
- * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
- *
- * Additionally the promise api allows for composition that is very hard to do with the
- * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
- * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
- * section on serial or parallel joining of promises.
- *
- * ## The Deferred API
- *
- * A new instance of deferred is constructed by calling `$q.defer()`.
- *
- * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
- * that can be used for signaling the successful or unsuccessful completion, as well as the status
- * of the task.
- *
- * **Methods**
- *
- * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
- *   constructed via `$q.reject`, the promise will be rejected instead.
- * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
- *   resolving it with a rejection constructed via `$q.reject`.
- * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
- *   multiple times before the promise is either resolved or rejected.
- *
- * **Properties**
- *
- * - promise – `{Promise}` – promise object associated with this deferred.
- *
- *
- * ## The Promise API
- *
- * A new promise instance is created when a deferred instance is created and can be retrieved by
- * calling `deferred.promise`.
- *
- * The purpose of the promise object is to allow for interested parties to get access to the result
- * of the deferred task when it completes.
- *
- * **Methods**
- *
- * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or
- *   will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
- *   as soon as the result is available. The callbacks are called with a single argument: the result
- *   or rejection reason. Additionally, the notify callback may be called zero or more times to
- *   provide a progress indication, before the promise is resolved or rejected.
- *
- *   This method *returns a new promise* which is resolved or rejected via the return value of the
- *   `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved
- *   with the value which is resolved in that promise using
- *   [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
- *   It also notifies via the return value of the `notifyCallback` method. The promise cannot be
- *   resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback
- *   arguments are optional.
- *
- * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
- *
- * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
- *   but to do so without modifying the final value. This is useful to release resources or do some
- *   clean-up that needs to be done whether the promise was rejected or resolved. See the [full
- *   specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
- *   more information.
- *
- * ## Chaining promises
- *
- * Because calling the `then` method of a promise returns a new derived promise, it is easily
- * possible to create a chain of promises:
- *
- * ```js
- *   promiseB = promiseA.then(function(result) {
- *     return result + 1;
- *   });
- *
- *   // promiseB will be resolved immediately after promiseA is resolved and its value
- *   // will be the result of promiseA incremented by 1
- * ```
- *
- * It is possible to create chains of any length and since a promise can be resolved with another
- * promise (which will defer its resolution further), it is possible to pause/defer resolution of
- * the promises at any point in the chain. This makes it possible to implement powerful APIs like
- * $http's response interceptors.
- *
- *
- * ## Differences between Kris Kowal's Q and $q
- *
- *  There are two main differences:
- *
- * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
- *   mechanism in AngularJS, which means faster propagation of resolution or rejection into your
- *   models and avoiding unnecessary browser repaints, which would result in flickering UI.
- * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
- *   all the important functionality needed for common async tasks.
- *
- * ## Testing
- *
- *  ```js
- *    it('should simulate promise', inject(function($q, $rootScope) {
- *      var deferred = $q.defer();
- *      var promise = deferred.promise;
- *      var resolvedValue;
- *
- *      promise.then(function(value) { resolvedValue = value; });
- *      expect(resolvedValue).toBeUndefined();
- *
- *      // Simulate resolving of promise
- *      deferred.resolve(123);
- *      // Note that the 'then' function does not get called synchronously.
- *      // This is because we want the promise API to always be async, whether or not
- *      // it got called synchronously or asynchronously.
- *      expect(resolvedValue).toBeUndefined();
- *
- *      // Propagate promise resolution to 'then' functions using $apply().
- *      $rootScope.$apply();
- *      expect(resolvedValue).toEqual(123);
- *    }));
- *  ```
- *
- * @param {function(function, function)} resolver Function which is responsible for resolving or
- *   rejecting the newly created promise. The first parameter is a function which resolves the
- *   promise, the second parameter is a function which rejects the promise.
- *
- * @returns {Promise} The newly created promise.

+   *   with the value which is resolved in that promise using
+   *   [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
+   *   It also notifies via the return value of the `notifyCallback` method. The promise cannot be
+   *   resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback
+   *   arguments are optional.
+   *
+   * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
+   *
+   * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
+   *   but to do so without modifying the final value. This is useful to release resources or do some
+   *   clean-up that needs to be done whether the promise was rejected or resolved. See the [full
+   *   specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
+   *   more information.
+   *
+   * ## Chaining promises
+   *
+   * Because calling the `then` method of a promise returns a new derived promise, it is easily
+   * possible to create a chain of promises:
+   *
+   * ```js
+   *   promiseB = promiseA.then(function(result) {
+   *     return result + 1;
+   *   });
+   *
+   *   // promiseB will be resolved immediately after promiseA is resolved and its value
+   *   // will be the result of promiseA incremented by 1
+   * ```
+   *
+   * It is possible to create chains of any length and since a promise can be resolved with another
+   * promise (which will defer its resolution further), it is possible to pause/defer resolution of
+   * the promises at any point in the chain. This makes it possible to implement powerful APIs like
+   * $http's response interceptors.
+   *
+   *
+   * ## Differences between Kris Kowal's Q and $q
+   *
+   *  There are two main differences:
+   *
+   * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
+   *   mechanism in AngularJS, which means faster propagation of resolution or rejection into your
+   *   models and avoiding unnecessary browser repaints, which would result in flickering UI.
+   * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
+   *   all the important functionality needed for common async tasks.
    *
-   * @param {boolean=} value Whether to generate an error when a rejected promise is not handled.
-   * @returns {boolean|ng.$qProvider} Current value when called without a new value or self for
-   *    chaining otherwise.
+   * ## Testing
+   *
+   *  ```js
+   *    it('should simulate promise', inject(function($q, $rootScope) {
+   *      var deferred = $q.defer();
+   *      var promise = deferred.promise;
+   *      var resolvedValue;
+   *
+   *      promise.then(function(value) { resolvedValue = value; });
+   *      expect(resolvedValue).toBeUndefined();
+   *
+   *      // Simulate resolving of promise
+   *      deferred.resolve(123);
+   *      // Note that the 'then' function does not get called synchronously.
+   *      // This is because we want the promise API to always be async, whether or not
+   *      // it got called synchronously or asynchronously.
+   *      expect(resolvedValue).toBeUndefined();
+   *
+   *      // Propagate promise resolution to 'then' functions using $apply().
+   *      $rootScope.$apply();
+   *      expect(resolvedValue).toEqual(123);
+   *    }));
+   *  ```
+   *
+   * @param {function(function, function)} resolver Function which is responsible for resolving or
+   *   rejecting the newly created promise. The first parameter is a function which resolves the
+   *   promise, the second parameter is a function which rejects the promise.
+   *
+   * @returns {Promise} The newly created promise.

        *
        * @description
-       * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
-       *
-       * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
-       *   $digest()} and should return the value that will be watched. (`watchExpression` should not change
-       *   its value when executed multiple times with the same input because it may be executed multiple
-       *   times by {@link ng.$rootScope.Scope#$digest $digest()}. That is, `watchExpression` should be
-       *   [idempotent](http://en.wikipedia.org/wiki/Idempotence).)
-       * - The `listener` is called only when the value from the current `watchExpression` and the
-       *   previous call to `watchExpression` are not equal (with the exception of the initial run,
-       *   see below). Inequality is determined according to reference inequality,
-       *   [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
-       *    via the `!==` Javascript operator, unless `objectEquality == true`
-       *   (see next point)
-       * - When `objectEquality == true`, inequality of the `watchExpression` is determined
-       *   according to the {@link angular.equals} function. To save the value of the object for
-       *   later comparison, the {@link angular.copy} function is used. This therefore means that
-       *   watching complex objects will have adverse memory and performance implications.
-       * - This should not be used to watch for changes in objects that are (or contain)
-       *   [File](https://developer.mozilla.org/docs/Web/API/File) objects due to limitations with {@link angular.copy `angular.copy`}.
-       * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
-       *   This is achieved by rerunning the watchers until no changes are detected. The rerun
-       *   iteration limit is 10 to prevent an infinite loop deadlock.
-       *
-       *
-       * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
-       * you can register a `watchExpression` function with no `listener`. (Be prepared for
-       * multiple calls to your `watchExpression` because it will execute multiple times in a
-       * single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.)
-       *
-       * After a watcher is registered with the scope, the `listener` fn is called asynchronously
-       * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
-       * watcher. In rare cases, this is undesirable because the listener is called when the result
-       * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
-       * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
-       * listener was called due to initialization.
-       *
-       *
-       *
-       * @example
-       * ```js
-           // let's assume that scope was dependency injected as the $rootScope
-           var scope = $rootScope;
-           scope.name = 'misko';

-             scope.counter = scope.counter + 1;
-           });
-           expect(scope.counter).toEqual(0);
-
-           scope.$digest();
-           // the listener is always called during the first $digest loop after it was registered
-           expect(scope.counter).toEqual(1);
-
-           scope.$digest();
-           // but now it will not be called unless the value changes
-           expect(scope.counter).toEqual(1);
-
-           scope.name = 'adam';
-           scope.$digest();

-             function() { return food; },

+         * @description
+         * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
+         *
+         * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
+         *   $digest()} and should return the value that will be watched. (`watchExpression` should not change
+         *   its value when executed multiple times with the same input because it may be executed multiple
+         *   times by {@link ng.$rootScope.Scope#$digest $digest()}. That is, `watchExpression` should be
+         *   [idempotent](http://en.wikipedia.org/wiki/Idempotence).)
+         * - The `listener` is called only when the value from the current `watchExpression` and the
+         *   previous call to `watchExpression` are not equal (with the exception of the initial run,
+         *   see below). Inequality is determined according to reference inequality,
+         *   [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
+         *    via the `!==` Javascript operator, unless `objectEquality == true`
+         *   (see next point)
+         * - When `objectEquality == true`, inequality of the `watchExpression` is determined
+         *   according to the {@link angular.equals} function. To save the value of the object for
+         *   later comparison, the {@link angular.copy} function is used. This therefore means that
+         *   watching complex objects will have adverse memory and performance implications.
+         * - This should not be used to watch for changes in objects that are (or contain)
+         *   [File](https://developer.mozilla.org/docs/Web/API/File) objects due to limitations with {@link angular.copy `angular.copy`}.
+         * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
+         *   This is achieved by rerunning the watchers until no changes are detected. The rerun
+         *   iteration limit is 10 to prevent an infinite loop deadlock.
+         *
+         *
+         * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
+         * you can register a `watchExpression` function with no `listener`. (Be prepared for
+         * multiple calls to your `watchExpression` because it will execute multiple times in a
+         * single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.)
+         *
+         * After a watcher is registered with the scope, the `listener` fn is called asynchronously
+         * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
+         * watcher. In rare cases, this is undesirable because the listener is called when the result
+         * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
+         * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
+         * listener was called due to initialization.
+         *
+         *
+         *
+         * @example
+         * ```js
+             // let's assume that scope was dependency injected as the $rootScope
+             var scope = $rootScope;
+             scope.name = 'misko';
+             scope.counter = 0;

+               scope.counter = scope.counter + 1;
+             });
+             expect(scope.counter).toEqual(0);
+              scope.$digest();
+             // the listener is always called during the first $digest loop after it was registered
+             expect(scope.counter).toEqual(1);
+              scope.$digest();
+             // but now it will not be called unless the value changes

+         * @description
+         * Shallow watches the properties of an object and fires whenever any of the properties change
+         * (for arrays, this implies watching the array items; for object maps, this implies watching
+         * the properties). If a change is detected, the `listener` callback is fired.
+         *
+         * - The `obj` collection is observed via standard $watch operation and is examined on every
+         *   call to $digest() to see if any items have been added, removed, or moved.
+         * - The `listener` is called whenever anything within the `obj` has changed. Examples include
+         *   adding, removing, and moving items belonging to an object or array.
+         *
+         *
+         * @example
+         * ```js
+            $scope.names = ['igor', 'matias', 'misko', 'james'];
+            $scope.dataCount = 4;
+             $scope.$watchCollection('names', function(newNames, oldNames) {

+            });
+             expect($scope.dataCount).toEqual(4);
+            $scope.$digest();
+             //still at 4 ... no changes

+         *    expression value should evaluate to an object or an array which is observed on each
+         *    {@link ng.$rootScope.Scope#$digest $digest} cycle. Any shallow change within the
+         *    collection will trigger a call to the `listener`.

+         *    - The `oldCollection` object is a copy of the former collection data.
+         *      Due to performance considerations, the`oldCollection` value is computed only if the
+         *      `listener` function declares two or more arguments.
+         *    - The `scope` argument refers to the current scope.

+         * @returns {function()} Returns a de-registration function for this listener. When the

+         * {@link ng.$compileProvider#directive directives}.
+         * Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within
+         * a {@link ng.$compileProvider#directive directive}), which will force a `$digest()`.
+         *
+         * If you want to be notified whenever `$digest()` is called,
+         * you can register a `watchExpression` function with
+         * {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`.
+         *
+         * In unit tests, you may need to call `$digest()` to simulate the scope life cycle.
+         *
+         * @example
+         * ```js
+             var scope = ...;
+             scope.name = 'misko';
+             scope.counter = 0;
+              expect(scope.counter).toEqual(0);
+             scope.$watch('name', function(newValue, oldValue) {
+               scope.counter = scope.counter + 1;

+             expect(scope.counter).toEqual(0);

-       *
-       * @description
-       * Suspend watchers of this scope subtree so that they will not be invoked during digest.
-       *
-       * This can be used to optimize your application when you know that running those watchers
-       * is redundant.
-       *
-       * **Warning**
-       *
-       * Suspending scopes from the digest cycle can have unwanted and difficult to debug results.
-       * Only use this approach if you are confident that you know what you are doing and have
-       * ample tests to ensure that bindings get updated as you expect.
-       *
-       * Some of the things to consider are:
-       *
-       * * Any external event on a directive/component will not trigger a digest while the hosting
-       *   scope is suspended - even if the event handler calls `$apply()` or `$rootScope.$digest()`.
-       * * Transcluded content exists on a scope that inherits from outside a directive but exists
-       *   as a child of the directive's containing scope. If the containing scope is suspended the
-       *   transcluded scope will also be suspended, even if the scope from which the transcluded
-       *   scope inherits is not suspended.
-       * * Multiple directives trying to manage the suspended status of a scope can confuse each other:
-       *    * A call to `$suspend()` on an already suspended scope is a no-op.
-       *    * A call to `$resume()` on a non-suspended scope is a no-op.
-       *    * If two directives suspend a scope, then one of them resumes the scope, the scope will no
-       *      longer be suspended. This could result in the other directive believing a scope to be
-       *      suspended when it is not.
-       * * If a parent scope is suspended then all its descendants will be also excluded from future
-       *   digests whether or not they have been suspended themselves. Note that this also applies to
-       *   isolate child scopes.
-       * * Calling `$digest()` directly on a descendant of a suspended scope will still run the watchers
-       *   for that scope and its descendants. When digesting we only check whether the current scope is
-       *   locally suspended, rather than checking whether it has a suspended ancestor.
-       * * Calling `$resume()` on a scope that has a suspended ancestor will not cause the scope to be
-       *   included in future digests until all its ancestors have been resumed.
-       * * Resolved promises, e.g. from explicit `$q` deferreds and `$http` calls, trigger `$apply()`
-       *   against the `$rootScope` and so will still trigger a global digest even if the promise was
-       *   initiated by a component that lives on a suspended scope.

+         * Suspend watchers of this scope subtree so that they will not be invoked during digest.
+         *
+         * This can be used to optimize your application when you know that running those watchers
+         * is redundant.
+         *
+         * **Warning**
+         *
+         * Suspending scopes from the digest cycle can have unwanted and difficult to debug results.
+         * Only use this approach if you are confident that you know what you are doing and have
+         * ample tests to ensure that bindings get updated as you expect.
+         *
+         * Some of the things to consider are:
+         *
+         * * Any external event on a directive/component will not trigger a digest while the hosting
+         *   scope is suspended - even if the event handler calls `$apply()` or `$rootScope.$digest()`.
+         * * Transcluded content exists on a scope that inherits from outside a directive but exists
+         *   as a child of the directive's containing scope. If the containing scope is suspended the
+         *   transcluded scope will also be suspended, even if the scope from which the transcluded
+         *   scope inherits is not suspended.
+         * * Multiple directives trying to manage the suspended status of a scope can confuse each other:
+         *    * A call to `$suspend()` on an already suspended scope is a no-op.
+         *    * A call to `$resume()` on a non-suspended scope is a no-op.
+         *    * If two directives suspend a scope, then one of them resumes the scope, the scope will no
+         *      longer be suspended. This could result in the other directive believing a scope to be
+         *      suspended when it is not.
+         * * If a parent scope is suspended then all its descendants will be also excluded from future
+         *   digests whether or not they have been suspended themselves. Note that this also applies to
+         *   isolate child scopes.
+         * * Calling `$digest()` directly on a descendant of a suspended scope will still run the watchers
+         *   for that scope and its descendants. When digesting we only check whether the current scope is
+         *   locally suspended, rather than checking whether it has a suspended ancestor.
+         * * Calling `$resume()` on a scope that has a suspended ancestor will not cause the scope to be
+         *   included in future digests until all its ancestors have been resumed.
+         * * Resolved promises, e.g. from explicit `$q` deferreds and `$http` calls, trigger `$apply()`
+         *   against the `$rootScope` and so will still trigger a global digest even if the promise was
+         *   initiated by a component that lives on a suspended scope.

- * `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict

- *
- * For an overview of this service and the functionnality it provides in AngularJS, see the main

- *
- * 

- * AngularJS strongly relies on contextual escaping for the security of bindings: disabling or

- * changes to this service will also influence users, so be extra careful and document your changes.
- * 

- *
- * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of
- * the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS.  This is
- * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to

- * @description
- *
- * The `$sceDelegateProvider` provider allows developers to configure the {@link ng.$sceDelegate
- * $sceDelegate service}, used as a delegate for {@link ng.$sce Strict Contextual Escaping (SCE)}.
- *
- * The `$sceDelegateProvider` allows one to get/set the whitelists and blacklists used to ensure
- * that the URLs used for sourcing AngularJS templates and other script-running URLs are safe (all
- * places that use the `$sce.RESOURCE_URL` context). See
- * {@link ng.$sceDelegateProvider#resourceUrlWhitelist $sceDelegateProvider.resourceUrlWhitelist}
- * and
- * {@link ng.$sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider.resourceUrlBlacklist},
- *
- * For the general details about this service in AngularJS, read the main page for {@link ng.$sce
- * Strict Contextual Escaping (SCE)}.
- *
- * **Example**:  Consider the following case. 
- *
- * - your app is hosted at url `http://myapp.example.com/`
- * - but some of your templates are hosted on other domains you control such as
- *   `http://srv01.assets.example.com/`, `http://srv02.assets.example.com/`, etc.
- * - and you have an open redirect at `http://myapp.example.com/clickThru?...`.
- *
- * Here is what a secure configuration for this scenario might look like:
- *
- * ```
- *  angular.module('myApp', []).config(function($sceDelegateProvider) {
- *    $sceDelegateProvider.resourceUrlWhitelist([
- *      // Allow same origin resource loads.
- *      'self',
- *      // Allow loading from our assets domain.  Notice the difference between * and **.
- *      'http://srv*.assets.example.com/**'
- *    ]);
- *
- *    // The blacklist overrides the whitelist so the open redirect here is blocked.
- *    $sceDelegateProvider.resourceUrlBlacklist([
- *      'http://myapp.example.com/clickThru**'
- *    ]);
- *  });
- * ```
- * Note that an empty whitelist will block every resource URL from being loaded, and will require
- * you to manually mark each one as trusted with `$sce.trustAsResourceUrl`. However, templates
- * requested by {@link ng.$templateRequest $templateRequest} that are present in
- * {@link ng.$templateCache $templateCache} will not go through this check. If you have a mechanism
- * to populate your templates in that cache at config time, then it is a good idea to remove 'self'
- * from that whitelist. This helps to mitigate the security impact of certain types of issues, like
- * for instance attacker-controlled `ng-includes`.

-/**
- * @ngdoc service
- * @name $sce
- * @kind function
- *
- * @description
- *
- * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
- *
- * ## Strict Contextual Escaping
- *
- * Strict Contextual Escaping (SCE) is a mode in which AngularJS constrains bindings to only render
- * trusted values. Its goal is to assist in writing code in a way that (a) is secure by default, and
- * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
- *
- * ### Overview
- *
- * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in
- * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically
- * run security checks on them (sanitizations, whitelists, depending on context), or throw when it
- * cannot guarantee the security of the result. That behavior depends strongly on contexts: HTML
- * can be sanitized, but template URLs cannot, for instance.
- *
- * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML:
- * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it
- * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and
- * render the input as-is, you will need to mark it as trusted for that context before attempting
- * to bind it.
- *
- * As of version 1.2, AngularJS ships with SCE enabled by default.
- *
- * ### In practice
- *
- * Here's an example of a binding in a privileged context:
- *
- * ```
- * 
- * 

- * ```
- *
- * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user.  With SCE
- * disabled, this application allows the user to render arbitrary HTML into the DIV, which would
- * be an XSS security bug. In a more realistic example, one may be rendering user comments, blog
- * articles, etc. via bindings. (HTML is just one example of a context where rendering user
- * controlled input creates security vulnerabilities.)
- *
- * For the case of HTML, you might use a library, either on the client side, or on the server side,
- * to sanitize unsafe HTML before binding to the value and rendering it in the document.
- *
- * How would you ensure that every place that used these types of bindings was bound to a value that
- * was sanitized by your library (or returned as safe for rendering by your server?)  How can you
- * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
- * properties/fields and forgot to update the binding to the sanitized value?
- *
- * To be secure by default, AngularJS makes sure bindings go through that sanitization, or
- * any similar validation process, unless there's a good reason to trust the given value in this
- * context.  That trust is formalized with a function call. This means that as a developer, you
- * can assume all untrusted bindings are safe. Then, to audit your code for binding security issues,
- * you just need to ensure the values you mark as trusted indeed are safe - because they were
- * received from your server, sanitized by your library, etc. You can organize your codebase to
- * help with this - perhaps allowing only the files in a specific directory to do this.
- * Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then
- * becomes a more manageable task.
- *
- * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
- * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
- * build the trusted versions of your values.
- *
- * ### How does it work?
- *
- * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
- * $sce.getTrusted(context, value)} rather than to the value directly.  Think of this function as
- * a way to enforce the required security context in your data sink. Directives use {@link
- * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs
- * the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also,
- * when binding without directives, AngularJS will understand the context of your bindings
- * automatically.
- *
- * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
- * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}.  Here's the actual code (slightly
- * simplified):
- *
- * ```
- * var ngBindHtmlDirective = ['$sce', function($sce) {
- *   return function(scope, element, attr) {
- *     scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
- *       element.html(value || '');
- *     });
- *   };
- * }];
- * ```
- *
- * ### Impact on loading templates
- *
- * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
- * `templateUrl`'s specified by {@link guide/directive directives}.
- *
- * By default, AngularJS only loads templates from the same domain and protocol as the application
- * document.  This is done by calling {@link ng.$sce#getTrustedResourceUrl
- * $sce.getTrustedResourceUrl} on the template URL.  To load templates from other domains and/or
- * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
- * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
- *
- * *Please note*:
- * The browser's
- * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
- * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
- * policy apply in addition to this and may further restrict whether the template is successfully
- * loaded.  This means that without the right CORS policy, loading templates from a different domain
- * won't work on all browsers.  Also, loading templates from `file://` URL does not work on some
- * browsers.
- *
- * ### This feels like too much overhead
- *
- * It's important to remember that SCE only applies to interpolation expressions.
- *
- * If your expressions are constant literals, they're automatically trusted and you don't need to
- * call `$sce.trustAs` on them (e.g.
- * `
`) just works (remember to include the
- * `ngSanitize` module). The `$sceDelegate` will also use the `$sanitize` service if it is available
- * when binding untrusted values to `$sce.HTML` context.
- * AngularJS provides an implementation in `angular-sanitize.js`, and if you
- * wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in
- * your application.
- *
- * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
- * templates in `ng-include` from your application's domain without having to even know about SCE.
- * It blocks loading templates from other domains or loading templates over http from an https
- * served document.  You can change these by setting your own custom {@link
- * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
- * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
- *
- * This significantly reduces the overhead.  It is far easier to pay the small overhead and have an
- * application that's secure and can be audited to verify that with much more ease than bolting
- * security onto an application later.
- *
- * 
- * ### What trusted context types are supported?
- *
- * | Context             | Notes          |
- * |---------------------|----------------|
- * | `$sce.HTML`         | For HTML that's safe to source into the application.  The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |
- * | `$sce.CSS`          | For CSS that's safe to source into the application.  Currently unused.  Feel free to use it in your own directives. |
- * | `$sce.MEDIA_URL`    | For URLs that are safe to render as media. Is automatically converted from string by sanitizing when needed. |
- * | `$sce.URL`          | For URLs that are safe to follow as links. Is automatically converted from string by sanitizing when needed. Note that `$sce.URL` makes a stronger statement about the URL than `$sce.MEDIA_URL` does and therefore contexts requiring values trusted for `$sce.URL` can be used anywhere that values trusted for `$sce.MEDIA_URL` are required.|
- * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application.  Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.)  

Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` or `$sce.MEDIA_URL` do and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` or `$sce.MEDIA_URL` are required. 

 The {@link $sceDelegateProvider#resourceUrlWhitelist $sceDelegateProvider#resourceUrlWhitelist()} and {@link $sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider#resourceUrlBlacklist()} can be used to restrict trusted origins for `RESOURCE_URL` |
- * | `$sce.JS`           | For JavaScript that is safe to execute in your application's context.  Currently unused.  Feel free to use it in your own directives. |
- *
- *
- * 

- * Be aware that, before AngularJS 1.7.0, `a[href]` and `img[src]` used to sanitize their
- * interpolated values directly rather than rely upon {@link ng.$sce#getTrusted `$sce.getTrusted`}.
- *
- * **As of 1.7.0, this is no longer the case.**
- *
- * Now such interpolations are marked as requiring `$sce.URL` (for `a[href]`) or `$sce.MEDIA_URL`
- * (for `img[src]`), so that the sanitization happens (via `$sce.getTrusted...`) when the `$interpolate`
- * service evaluates the expressions.
- * 

- *
- * There are no CSS or JS context bindings in AngularJS currently, so their corresponding `$sce.trustAs`
- * functions aren't useful yet. This might evolve.
- *
- * ### Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} 
- *
- *  Each element in these arrays must be one of the following:
- *
- *  - **'self'**
- *    - The special **string**, `'self'`, can be used to match against all URLs of the **same
- *      domain** as the application document using the **same protocol**.
- *  - **String** (except the special value `'self'`)
- *    - The string is matched against the full *normalized / absolute URL* of the resource
- *      being tested (substring matches are not good enough.)
- *    - There are exactly **two wildcard sequences** - `*` and `**`.  All other characters
- *      match themselves.
- *    - `*`: matches zero or more occurrences of any character other than one of the following 6
- *      characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'.  It's a useful wildcard for use
- *      in a whitelist.
- *    - `**`: matches zero or more occurrences of *any* character.  As such, it's not
- *      appropriate for use in a scheme, domain, etc. as it would match too much.  (e.g.
- *      http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
- *      not have been the intention.)  Its usage at the very end of the path is ok.  (e.g.
- *      http://foo.example.com/templates/**).
- *  - **RegExp** (*see caveat below*)
- *    - *Caveat*:  While regular expressions are powerful and offer great flexibility,  their syntax
- *      (and all the inevitable escaping) makes them *harder to maintain*.  It's easy to
- *      accidentally introduce a bug when one updates a complex expression (imho, all regexes should
- *      have good test coverage).  For instance, the use of `.` in the regex is correct only in a
- *      small number of cases.  A `.` character in the regex used when matching the scheme or a
- *      subdomain could be matched against a `:` or literal `.` that was likely not intended.   It
- *      is highly recommended to use the string patterns and only fall back to regular expressions
- *      as a last resort.
- *    - The regular expression must be an instance of RegExp (i.e. not a string.)  It is
- *      matched against the **entire** *normalized / absolute URL* of the resource being tested
- *      (even when the RegExp did not have the `^` and `$` codes.)  In addition, any flags
- *      present on the RegExp (such as multiline, global, ignoreCase) are ignored.
- *    - If you are generating your JavaScript from some other templating engine (not
- *      recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
- *      remember to escape your regular expression (and be aware that you might need more than
- *      one level of escaping depending on your templating engine and the way you interpolated
- *      the value.)  Do make use of your platform's escaping mechanism as it might be good
- *      enough before coding your own.  E.g. Ruby has
- *      [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
- *      and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
- *      Javascript lacks a similar built in function for escaping.  Take a look at Google
- *      Closure library's [goog.string.regExpEscape(s)](
- *      http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).

- *
- * ## Can I disable SCE completely?
- *
- * Yes, you can.  However, this is strongly discouraged.  SCE gives you a lot of security benefits
- * for little coding overhead.  It will be much harder to take an SCE disabled application and
- * either secure it on your own or enable SCE at a later stage.  It might make sense to disable SCE
- * for cases where you have a lot of existing code that was written before SCE was introduced and
- * you're migrating them a module at a time. Also do note that this is an app-wide setting, so if
- * you are writing a library, you will cause security bugs applications using it.
- *
- * That said, here's how you can completely disable SCE:
- *
- * ```
- * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
- *   // Completely disable SCE.  For demonstration purposes only!
- *   // Do not use in new projects or libraries.
- *   $sceProvider.enabled(false);
- * });
- * ```
- *

+   *
+   * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
+   *
+   * ## Strict Contextual Escaping
+   *
+   * Strict Contextual Escaping (SCE) is a mode in which AngularJS constrains bindings to only render
+   * trusted values. Its goal is to assist in writing code in a way that (a) is secure by default, and
+   * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
+   *
+   * ### Overview
+   *
+   * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in
+   * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically
+   * run security checks on them (sanitizations, whitelists, depending on context), or throw when it
+   * cannot guarantee the security of the result. That behavior depends strongly on contexts: HTML
+   * can be sanitized, but template URLs cannot, for instance.
+   *
+   * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML:
+   * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it
+   * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and
+   * render the input as-is, you will need to mark it as trusted for that context before attempting
+   * to bind it.
+   *
+   * As of version 1.2, AngularJS ships with SCE enabled by default.
+   *
+   * ### In practice
+   *
+   * Here's an example of a binding in a privileged context:
+   *
+   * ```
+   * 
+   * 

+   * ```
    *
-   * The API contract for the SCE delegate
-   * -------------------------------------
-   * The SCE delegate object must provide the following 3 methods:
+   * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user.  With SCE
+   * disabled, this application allows the user to render arbitrary HTML into the DIV, which would
+   * be an XSS security bug. In a more realistic example, one may be rendering user comments, blog
+   * articles, etc. via bindings. (HTML is just one example of a context where rendering user
+   * controlled input creates security vulnerabilities.)
+   *
+   * For the case of HTML, you might use a library, either on the client side, or on the server side,
+   * to sanitize unsafe HTML before binding to the value and rendering it in the document.
+   *
+   * How would you ensure that every place that used these types of bindings was bound to a value that
+   * was sanitized by your library (or returned as safe for rendering by your server?)  How can you
+   * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
+   * properties/fields and forgot to update the binding to the sanitized value?
+   *
+   * To be secure by default, AngularJS makes sure bindings go through that sanitization, or
+   * any similar validation process, unless there's a good reason to trust the given value in this
+   * context.  That trust is formalized with a function call. This means that as a developer, you
+   * can assume all untrusted bindings are safe. Then, to audit your code for binding security issues,
+   * you just need to ensure the values you mark as trusted indeed are safe - because they were
+   * received from your server, sanitized by your library, etc. You can organize your codebase to
+   * help with this - perhaps allowing only the files in a specific directory to do this.
+   * Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then
+   * becomes a more manageable task.
+   *
+   * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
+   * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
+   * build the trusted versions of your values.
+   *
+   * ### How does it work?
+   *
+   * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
+   * $sce.getTrusted(context, value)} rather than to the value directly.  Think of this function as
+   * a way to enforce the required security context in your data sink. Directives use {@link
+   * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs
+   * the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also,
+   * when binding without directives, AngularJS will understand the context of your bindings
+   * automatically.
+   *
+   * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
+   * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}.  Here's the actual code (slightly
+   * simplified):
    *
-   * - trustAs(contextEnum, value)
-   *     This method is used to tell the SCE service that the provided value is OK to use in the
-   *     contexts specified by contextEnum.  It must return an object that will be accepted by
-   *     getTrusted() for a compatible contextEnum and return this value.
+   * ```
+   * var ngBindHtmlDirective = ['$sce', function($sce) {
+   *   return function(scope, element, attr) {
+   *     scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
+   *       element.html(value || '');
+   *     });
+   *   };
+   * }];
+   * ```
+   *
+   * ### Impact on loading templates
+   *
+   * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
+   * `templateUrl`'s specified by {@link guide/directive directives}.
+   *
+   * By default, AngularJS only loads templates from the same domain and protocol as the application
+   * document.  This is done by calling {@link ng.$sce#getTrustedResourceUrl
+   * $sce.getTrustedResourceUrl} on the template URL.  To load templates from other domains and/or
+   * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
+   * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
+   *
+   * *Please note*:
+   * The browser's
+   * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
+   * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
+   * policy apply in addition to this and may further restrict whether the template is successfully
+   * loaded.  This means that without the right CORS policy, loading templates from a different domain
+   * won't work on all browsers.  Also, loading templates from `file://` URL does not work on some
+   * browsers.
+   *
+   * ### This feels like too much overhead
+   *
+   * It's important to remember that SCE only applies to interpolation expressions.
+   *
+   * If your expressions are constant literals, they're automatically trusted and you don't need to
+   * call `$sce.trustAs` on them (e.g.
+   * `
`) just works (remember to include the
+   * `ngSanitize` module). The `$sceDelegate` will also use the `$sanitize` service if it is available
+   * when binding untrusted values to `$sce.HTML` context.
+   * AngularJS provides an implementation in `angular-sanitize.js`, and if you
+   * wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in
+   * your application.
+   *
+   * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
+   * templates in `ng-include` from your application's domain without having to even know about SCE.
+   * It blocks loading templates from other domains or loading templates over http from an https
+   * served document.  You can change these by setting your own custom {@link
+   * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
+   * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
+   *
+   * This significantly reduces the overhead.  It is far easier to pay the small overhead and have an
+   * application that's secure and can be audited to verify that with much more ease than bolting
+   * security onto an application later.
+   *
+   * 
+   * ### What trusted context types are supported?
+   *
+   * | Context             | Notes          |
+   * |---------------------|----------------|
+   * | `$sce.HTML`         | For HTML that's safe to source into the application.  The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |
+   * | `$sce.CSS`          | For CSS that's safe to source into the application.  Currently unused.  Feel free to use it in your own directives. |
+   * | `$sce.MEDIA_URL`    | For URLs that are safe to render as media. Is automatically converted from string by sanitizing when needed. |
+   * | `$sce.URL`          | For URLs that are safe to follow as links. Is automatically converted from string by sanitizing when needed. Note that `$sce.URL` makes a stronger statement about the URL than `$sce.MEDIA_URL` does and therefore contexts requiring values trusted for `$sce.URL` can be used anywhere that values trusted for `$sce.MEDIA_URL` are required.|
+   * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application.  Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.)  

Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` or `$sce.MEDIA_URL` do and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` or `$sce.MEDIA_URL` are required. 

 The {@link $sceDelegateProvider#resourceUrlWhitelist $sceDelegateProvider#resourceUrlWhitelist()} and {@link $sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider#resourceUrlBlacklist()} can be used to restrict trusted origins for `RESOURCE_URL` |
+   * | `$sce.JS`           | For JavaScript that is safe to execute in your application's context.  Currently unused.  Feel free to use it in your own directives. |
+   *
+   *
+   * 

+   * Be aware that, before AngularJS 1.7.0, `a[href]` and `img[src]` used to sanitize their
+   * interpolated values directly rather than rely upon {@link ng.$sce#getTrusted `$sce.getTrusted`}.
+   *
+   * **As of 1.7.0, this is no longer the case.**
+   *
+   * Now such interpolations are marked as requiring `$sce.URL` (for `a[href]`) or `$sce.MEDIA_URL`
+   * (for `img[src]`), so that the sanitization happens (via `$sce.getTrusted...`) when the `$interpolate`
+   * service evaluates the expressions.
+   * 

    *
-   * - valueOf(value)
-   *     For values that were not produced by trustAs(), return them as is.  For values that were
-   *     produced by trustAs(), return the corresponding input value to trustAs.  Basically, if
-   *     trustAs is wrapping the given values into some type, this operation unwraps it when given
-   *     such a value.
+   * There are no CSS or JS context bindings in AngularJS currently, so their corresponding `$sce.trustAs`
+   * functions aren't useful yet. This might evolve.
+   *
+   * ### Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} 
+   *
+   *  Each element in these arrays must be one of the following:
+   *
+   *  - **'self'**
+   *    - The special **string**, `'self'`, can be used to match against all URLs of the **same
+   *      domain** as the application document using the **same protocol**.
+   *  - **String** (except the special value `'self'`)
+   *    - The string is matched against the full *normalized / absolute URL* of the resource
+   *      being tested (substring matches are not good enough.)
+   *    - There are exactly **two wildcard sequences** - `*` and `**`.  All other characters
+   *      match themselves.
+   *    - `*`: matches zero or more occurrences of any character other than one of the following 6
+   *      characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'.  It's a useful wildcard for use
+   *      in a whitelist.
+   *    - `**`: matches zero or more occurrences of *any* character.  As such, it's not
+   *      appropriate for use in a scheme, domain, etc. as it would match too much.  (e.g.
+   *      http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
+   *      not have been the intention.)  Its usage at the very end of the path is ok.  (e.g.
+   *      http://foo.example.com/templates/**).
+   *  - **RegExp** (*see caveat below*)
+   *    - *Caveat*:  While regular expressions are powerful and offer great flexibility,  their syntax
+   *      (and all the inevitable escaping) makes them *harder to maintain*.  It's easy to
+   *      accidentally introduce a bug when one updates a complex expression (imho, all regexes should
+   *      have good test coverage).  For instance, the use of `.` in the regex is correct only in a
+   *      small number of cases.  A `.` character in the regex used when matching the scheme or a

-   * - getTrusted(contextEnum, value)
-   *     This function should return the value that is safe to use in the context specified by
-   *     contextEnum or throw and exception otherwise.
    *
-   * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
-   * opaque or wrapped in some holder object.  That happens to be an implementation detail.  For
-   * instance, an implementation could maintain a registry of all trusted objects by context.  In
-   * such a case, trustAs() would return the same object that was passed in.  getTrusted() would
-   * return the same object passed in if it was found in the registry under a compatible context or
-   * throw an exception otherwise.  An implementation might only wrap values some of the time based
-   * on some criteria.  getTrusted() might return a value and not throw an exception for special
-   * constants or objects even if not wrapped.  All such implementations fulfill this contract.
    *
+   * ## Can I disable SCE completely?
    *
-   * A note on the inheritance model for SCE contexts
-   * ------------------------------------------------
-   * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types.  This
-   * is purely an implementation details.
+   * Yes, you can.  However, this is strongly discouraged.  SCE gives you a lot of security benefits
+   * for little coding overhead.  It will be much harder to take an SCE disabled application and
+   * either secure it on your own or enable SCE at a later stage.  It might make sense to disable SCE
+   * for cases where you have a lot of existing code that was written before SCE was introduced and
+   * you're migrating them a module at a time. Also do note that this is an app-wide setting, so if
+   * you are writing a library, you will cause security bugs applications using it.
    *
-   * The contract is simply this:
+   * That said, here's how you can completely disable SCE:
    *
-   *     getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
-   *     will also succeed.
+   * ```
+   * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
+   *   // Completely disable SCE.  For demonstration purposes only!
+   *   // Do not use in new projects or libraries.
+   *   $sceProvider.enabled(false);
+   * });
+   * ```
    *
-   * Inheritance happens to capture this in a natural way. In some future, we may not use
-   * inheritance anymore. That is OK because no code outside of sce.js and sceSpecs.js would need to
-   * be aware of this detail.

- *
- * Implementation Notes for non-IE browsers
- * ----------------------------------------
- * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
- * results both in the normalizing and parsing of the URL.  Normalizing means that a relative
- * URL will be resolved into an absolute URL in the context of the application document.
- * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
- * properties are all populated to reflect the normalized URL.  This approach has wide
- * compatibility - Safari 1+, Mozilla 1+ etc.  See
- * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
- *
- * Implementation Notes for IE
- * ---------------------------
- * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
- * browsers.  However, the parsed components will not be set if the URL assigned did not specify
- * them.  (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.)  We
- * work around that by performing the parsing in a 2nd step by taking a previously normalized
- * URL (e.g. by assigning to a.href) and assigning it a.href again.  This correctly populates the
- * properties such as protocol, hostname, port, etc.

-/**
- * @ngdoc filter
- * @name filter
- * @kind function
- *
- * @description
- * Selects a subset of items from `array` and returns it as a new array.
- *
- * @param {Array} array The source array.
- * 

- *   **Note**: If the array contains objects that reference themselves, filtering is not possible.
- * 

- * @param {string|Object|function()} expression The predicate to be used for selecting items from
- *   `array`.
- *
- *   Can be one of:
- *
- *   - `string`: The string is used for matching against the contents of the `array`. All strings or
- *     objects with string properties in `array` that match this string will be returned. This also
- *     applies to nested object properties.
- *     The predicate can be negated by prefixing the string with `!`.
- *
- *   - `Object`: A pattern object can be used to filter specific properties on objects contained
- *     by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
- *     which have property `name` containing "M" and property `phone` containing "1". A special
- *     property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match
- *     against any property of the object or its nested object properties. That's equivalent to the
- *     simple substring match with a `string` as described above. The special property name can be
- *     overwritten, using the `anyPropertyKey` parameter.
- *     The predicate can be negated by prefixing the string with `!`.
- *     For example `{name: "!M"}` predicate will return an array of items which have property `name`
- *     not containing "M".
- *
- *     Note that a named property will match properties on the same level only, while the special
- *     `$` property will match properties on the same level or deeper. E.g. an array item like
- *     `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
- *     **will** be matched by `{$: 'John'}`.
- *
- *   - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
- *     The function is called for each element of the array, with the element, its index, and
- *     the entire array itself as arguments.
- *
- *     The final result is an array of those elements that the predicate returned true for.
- *
- * @param {function(actual, expected)|true|false} [comparator] Comparator which is used in
- *     determining if values retrieved using `expression` (when it is not a function) should be
- *     considered a match based on the expected value (from the filter expression) and actual
- *     value (from the object in the array).
- *
- *   Can be one of:
- *
- *   - `function(actual, expected)`:
- *     The function will be given the object value and the predicate value to compare and
- *     should return true if both values should be considered equal.
- *
- *   - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
- *     This is essentially strict comparison of expected and actual.
- *
- *   - `false`: A short hand for a function which will look for a substring match in a case
- *     insensitive way. Primitive values are converted to strings. Objects are not compared against
- *     primitives, unless they have a custom `toString` method (e.g. `Date` objects).
- *
- *
- *   Defaults to `false`.
- *
- * @param {string} [anyPropertyKey] The special property name that matches against any property.
- *     By default `$`.
- *
- * @example

- *   * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
- *   * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
- *   * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
- *   * `'MMMM'`: Month in year (January-December)
- *   * `'MMM'`: Month in year (Jan-Dec)
- *   * `'MM'`: Month in year, padded (01-12)
- *   * `'M'`: Month in year (1-12)
- *   * `'LLLL'`: Stand-alone month in year (January-December)
- *   * `'dd'`: Day in month, padded (01-31)
- *   * `'d'`: Day in month (1-31)
- *   * `'EEEE'`: Day in Week,(Sunday-Saturday)
- *   * `'EEE'`: Day in Week, (Sun-Sat)
- *   * `'HH'`: Hour in day, padded (00-23)
- *   * `'H'`: Hour in day (0-23)
- *   * `'hh'`: Hour in AM/PM, padded (01-12)
- *   * `'h'`: Hour in AM/PM, (1-12)
- *   * `'mm'`: Minute in hour, padded (00-59)
- *   * `'m'`: Minute in hour (0-59)
- *   * `'ss'`: Second in minute, padded (00-59)
- *   * `'s'`: Second in minute (0-59)
- *   * `'sss'`: Millisecond in second, padded (000-999)
- *   * `'a'`: AM/PM marker
- *   * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
- *   * `'ww'`: Week of year, padded (00-53). Week 01 is the week with the first Thursday of the year
- *   * `'w'`: Week of year (0-53). Week 1 is the week with the first Thursday of the year
- *   * `'G'`, `'GG'`, `'GGG'`: The abbreviated form of the era string (e.g. 'AD')
- *   * `'GGGG'`: The long form of the era string (e.g. 'Anno Domini')
- *
- *   `format` string can also be one of the following predefined
- *   {@link guide/i18n localizable formats}:
- *
- *   * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
- *     (e.g. Sep 3, 2010 12:05:08 PM)
- *   * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US  locale (e.g. 9/3/10 12:05 PM)
- *   * `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` for en_US  locale
- *     (e.g. Friday, September 3, 2010)
- *   * `'longDate'`: equivalent to `'MMMM d, y'` for en_US  locale (e.g. September 3, 2010)
- *   * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US  locale (e.g. Sep 3, 2010)

- *   * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 PM)
- *   * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 PM)
- *
- *   `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g.
- *   `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence
- *   (e.g. `"h 'o''clock'"`).
- *
- *   Any other characters in the `format` string will be output as-is.
- *
- * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
- *    number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its
- *    shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
- *    specified in the string input, the time is considered to be in the local timezone.
- * @param {string=} format Formatting rules (see Description). If not specified,
- *    `mediumDate` is used.
- * @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the
- *    continental US time zone abbreviations, but for general use, use a time zone offset, for
- *    example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
- *    If not specified, the timezone of the browser will be used.
- * @returns {string} Formatted string or the input if input is not recognized as date/millis.
- *

+   *   * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 PM)
+   *
+   *   `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g.
+   *   `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence
+   *   (e.g. `"h 'o''clock'"`).
+   *
+   *   Any other characters in the `format` string will be output as-is.
+   *
+   * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
+   *    number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its
+   *    shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
+   *    specified in the string input, the time is considered to be in the local timezone.
+   * @param {string=} format Formatting rules (see Description). If not specified,
+   *    `mediumDate` is used.
+   * @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the
+   *    continental US time zone abbreviations, but for general use, use a time zone offset, for
+   *    example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
+   *    If not specified, the timezone of the browser will be used.
+   * @returns {string} Formatted string or the input if input is not recognized as date/millis.
+   *
+   * @example
+     
+       
+         {{1288323623006 | date:'medium'}}:

-/**
- * @ngdoc filter
- * @name limitTo
- * @kind function
- *
- * @description
- * Creates a new array or string containing only a specified number of elements. The elements are
- * taken from either the beginning or the end of the source array, string or number, as specified by
- * the value and sign (positive or negative) of `limit`. Other array-like objects are also supported
- * (e.g. array subclasses, NodeLists, jqLite/jQuery collections etc). If a number is used as input,
- * it is converted to a string.
- *
- * @param {Array|ArrayLike|string|number} input - Array/array-like, string or number to be limited.
- * @param {string|number} limit - The length of the returned array or string. If the `limit` number
- *     is positive, `limit` number of items from the beginning of the source array/string are copied.
- *     If the number is negative, `limit` number  of items from the end of the source array/string
- *     are copied. The `limit` will be trimmed if it exceeds `array.length`. If `limit` is undefined,
- *     the input will be returned unchanged.
- * @param {(string|number)=} begin - Index at which to begin limitation. As a negative index,
- *     `begin` indicates an offset from the end of `input`. Defaults to `0`.
- * @returns {Array|string} A new sub-array or substring of length `limit` or less if the input had
- *     less than `limit` elements.
- *

-/**
- * @ngdoc filter
- * @name orderBy
- * @kind function
- *
- * @description
- * Returns an array containing the items from the specified `collection`, ordered by a `comparator`
- * function based on the values computed using the `expression` predicate.
- *
- * For example, `[{id: 'foo'}, {id: 'bar'}] | orderBy:'id'` would result in
- * `[{id: 'bar'}, {id: 'foo'}]`.
- *
- * The `collection` can be an Array or array-like object (e.g. NodeList, jQuery object, TypedArray,
- * String, etc).
- *
- * The `expression` can be a single predicate, or a list of predicates each serving as a tie-breaker
- * for the preceding one. The `expression` is evaluated against each item and the output is used
- * for comparing with other items.
- *
- * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in
- * ascending order.
- *
- * The comparison is done using the `comparator` function. If none is specified, a default, built-in
- * comparator is used (see below for details - in a nutshell, it compares numbers numerically and
- * strings alphabetically).
- *
- * ### Under the hood
- *
- * Ordering the specified `collection` happens in two phases:
- *
- * 1. All items are passed through the predicate (or predicates), and the returned values are saved
- *    along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed
- *    through a predicate that extracts the value of the `label` property, would be transformed to:
- *    ```
- *    {
- *      value: 'foo',
- *      type: 'string',
- *      index: ...
- *    }
- *    ```
- *    **Note:** `null` values use `'null'` as their type.
- * 2. The comparator function is used to sort the items, based on the derived values, types and
- *    indices.
- *
- * If you use a custom comparator, it will be called with pairs of objects of the form
- * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal
- * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the
- * second, or `1` otherwise.
- *
- * In order to ensure that the sorting will be deterministic across platforms, if none of the
- * specified predicates can distinguish between two items, `orderBy` will automatically introduce a
- * dummy predicate that returns the item's index as `value`.
- * (If you are using a custom comparator, make sure it can handle this predicate as well.)
- *
- * If a custom comparator still can't distinguish between two items, then they will be sorted based
- * on their index using the built-in comparator.
- *
- * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted
- * value for an item, `orderBy` will try to convert that object to a primitive value, before passing
- * it to the comparator. The following rules govern the conversion:
- *
- * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be
- *    used instead.

- *    (If the object has a `valueOf()` method that returns another object, then the returned object
- *    will be used in subsequent steps.)
- * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that
- *    returns a primitive, its return value will be used instead.

- *    (If the object has a `toString()` method that returns another object, then the returned object
- *    will be used in subsequent steps.)
- * 3. No conversion; the object itself is used.
- *
- * ### The default comparator
- *
- * The default, built-in comparator should be sufficient for most usecases. In short, it compares
- * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to
- * using their index in the original collection, sorts values of different types by type and puts
- * `undefined` and `null` values at the end of the sorted list.
- *
- * More specifically, it follows these steps to determine the relative order of items:
- *
- * 1. If the compared values are of different types:
- *    - If one of the values is undefined, consider it "greater than" the other.
- *    - Else if one of the values is null, consider it "greater than" the other.
- *    - Else compare the types themselves alphabetically.
- * 2. If both values are of type `string`, compare them alphabetically in a case- and
- *    locale-insensitive way.
- * 3. If both values are objects, compare their indices instead.
- * 4. Otherwise, return:
- *    -  `0`, if the values are equal (by strict equality comparison, i.e. using `===`).
- *    - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator).
- *    -  `1`, otherwise.
- *
- * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being
- *           saved as numbers and not strings.
- * **Note:** For the purpose of sorting, `null` and `undefined` are considered "greater than"
- *           any other value (with undefined "greater than" null). This effectively means that `null`
- *           and `undefined` values end up at the end of a list sorted in ascending order.
- * **Note:** `null` values use `'null'` as their type to be able to distinguish them from objects.
- *
- * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort.
- * @param {(Function|string|Array.)=} expression - A predicate (or list of
- *    predicates) to be used by the comparator to determine the order of elements.
- *
- *    Can be one of:
- *
- *    - `Function`: A getter function. This function will be called with each item as argument and
- *      the return value will be used for sorting.
- *    - `string`: An AngularJS expression. This expression will be evaluated against each item and the
- *      result will be used for sorting. For example, use `'label'` to sort by a property called
- *      `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`
- *      property.

- *      (The result of a constant expression is interpreted as a property name to be used for
- *      comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a
- *      property called `special name`.)

- *      An expression can be optionally prefixed with `+` or `-` to control the sorting direction,
- *      ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided,
- *      (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons.
- *    - `Array`: An array of function and/or string predicates. If a predicate cannot determine the
- *      relative order of two items, the next predicate is used as a tie-breaker.
- *
- * **Note:** If the predicate is missing or empty then it defaults to `'+'`.
- *
- * @param {boolean=} reverse - If `true`, reverse the sorting order.
- * @param {(Function)=} comparator - The comparator function used to determine the relative order of
- *    value pairs. If omitted, the built-in comparator will be used.
- *
- * @returns {Array} - The sorted array.
- *
- *
- * @example
- * ### Ordering a table with `ngRepeat`
- *
- * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by
- * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means
- * it defaults to the built-in comparator.
- *

- * ### Using a custom comparator
- *
- * If you have very specific requirements about the way items are sorted, you can pass your own
- * comparator function. For example, you might need to compare some strings in a locale-sensitive
- * way. (When specifying a custom comparator, you also need to pass a value for the `reverse`
- * argument - passing `false` retains the default sorting order, i.e. ascending.)

- *
- * @description
- * Directive that instantiates
- * {@link form.FormController FormController}.
- *
- * If the `name` attribute is specified, the form controller is published onto the current scope under
- * this name.
- *
- * ## Alias: {@link ng.directive:ngForm `ngForm`}
- *
- * In AngularJS, forms can be nested. This means that the outer form is valid when all of the child
- * forms are valid as well. However, browsers do not allow nesting of `` elements, so
- * AngularJS provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to
- * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group
- * of controls needs to be determined.
- *
- * ## CSS classes
- *  - `ng-valid` is set if the form is valid.
- *  - `ng-invalid` is set if the form is invalid.
- *  - `ng-pending` is set if the form is pending.
- *  - `ng-pristine` is set if the form is pristine.
- *  - `ng-dirty` is set if the form is dirty.
- *  - `ng-submitted` is set if the form was submitted.
- *
- * Keep in mind that ngAnimate can detect each of these classes when added and removed.
- *
- *
- * ## Submitting a form and preventing the default action
- *
- * Since the role of forms in client-side AngularJS applications is different than in classical
- * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
- * page reload that sends the data to the server. Instead some javascript logic should be triggered
- * to handle the form submission in an application-specific way.
- *
- * For this reason, AngularJS prevents the default action (form submission to the server) unless the
- * `` element has an `action` attribute specified.
- *
- * You can use one of the following two ways to specify what javascript method should be called when
- * a form is submitted:
- *
- * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
- * - {@link ng.directive:ngClick ngClick} directive on the first
-  *  button or input field of type submit (input[type=submit])
- *
- * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
- * or {@link ng.directive:ngClick ngClick} directives.
- * This is because of the following form submission rules in the HTML specification:
- *
- * - If a form has only one input field then hitting enter in this field triggers form submit
- * (`ngSubmit`)
- * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
- * doesn't trigger submit
- * - if a form has one or more input fields and one or more buttons or input[type=submit] then
- * hitting enter in any of the input fields will trigger the click handler on the *first* button or
- * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
- *
- * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is
- * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
- * to have access to the updated model.
- *
- * @animations
- * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.
- * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any
- * other validations that are performed within the form. Animations in ngForm are similar to how
- * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well
- * as JS animations.
- *
- * The following example shows a simple way to utilize CSS transitions to style a form element
- * that has been rendered as invalid after it has been validated:
- *
- * 
- * //be sure to include ngAnimate as a module to hook into more
- * //advanced animations
- * .my-form {
- *   transition:0.5s linear all;
- *   background: white;
- * }
- * .my-form.ng-invalid {
- *   background: red;
- *   color:white;
- * }
- * 

- *
- * @example
-    
-      
-       
-

+   * @description
+   * Helper directive that makes it possible to create control groups inside a
+   * {@link ng.directive:form `form`} directive.
+   * These "child forms" can be used, for example, to determine the validity of a sub-group of

+   *
+   * 

+   * **Note**: `ngForm` cannot be used as a replacement for `
`, because it lacks its
+   * [built-in HTML functionality](https://html.spec.whatwg.org/#the-form-element).
+   * Specifically, you cannot submit `ngForm` like a `` tag. That means,
+   * you cannot send data to the server with `ngForm`, or integrate it with
+   * {@link ng.directive:ngSubmit `ngSubmit`}.
+   * 

+   *

+  /**
+  * @ngdoc directive
+  * @name form
+  * @restrict E
+  *
+  * @description
+  * Directive that instantiates
+  * {@link form.FormController FormController}.
+  *
+  * If the `name` attribute is specified, the form controller is published onto the current scope under
+  * this name.
+  *
+  * ## Alias: {@link ng.directive:ngForm `ngForm`}
+  *
+  * In AngularJS, forms can be nested. This means that the outer form is valid when all of the child
+  * forms are valid as well. However, browsers do not allow nesting of `` elements, so
+  * AngularJS provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to
+  * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group
+  * of controls needs to be determined.
+  *
+  * ## CSS classes
+  *  - `ng-valid` is set if the form is valid.
+  *  - `ng-invalid` is set if the form is invalid.
+  *  - `ng-pending` is set if the form is pending.
+  *  - `ng-pristine` is set if the form is pristine.
+  *  - `ng-dirty` is set if the form is dirty.
+  *  - `ng-submitted` is set if the form was submitted.
+  *
+  * Keep in mind that ngAnimate can detect each of these classes when added and removed.
+  *
+  *
+  * ## Submitting a form and preventing the default action
+  *
+  * Since the role of forms in client-side AngularJS applications is different than in classical
+  * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
+  * page reload that sends the data to the server. Instead some javascript logic should be triggered
+  * to handle the form submission in an application-specific way.
+  *
+  * For this reason, AngularJS prevents the default action (form submission to the server) unless the
+  * `` element has an `action` attribute specified.
+  *
+  * You can use one of the following two ways to specify what javascript method should be called when
+  * a form is submitted:
+  *
+  * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
+  * - {@link ng.directive:ngClick ngClick} directive on the first
+   *  button or input field of type submit (input[type=submit])
+  *
+  * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
+  * or {@link ng.directive:ngClick ngClick} directives.
+  * This is because of the following form submission rules in the HTML specification:
+  *
+  * - If a form has only one input field then hitting enter in this field triggers form submit
+  * (`ngSubmit`)
+  * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
+  * doesn't trigger submit
+  * - if a form has one or more input fields and one or more buttons or input[type=submit] then
+  * hitting enter in any of the input fields will trigger the click handler on the *first* button or
+  * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
+  *
+  * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is
+  * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
+  * to have access to the updated model.
+  *
+  * @animations
+  * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.
+  * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any
+  * other validations that are performed within the form. Animations in ngForm are similar to how
+  * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well
+  * as JS animations.
+  *
+  * The following example shows a simple way to utilize CSS transitions to style a form element
+  * that has been rendered as invalid after it has been validated:
+  *
+  * 
+  * //be sure to include ngAnimate as a module to hook into more
+  * //advanced animations
+  * .my-form {
+  *   transition:0.5s linear all;
+  *   background: white;
+  * }
+  * .my-form.ng-invalid {
+  *   background: red;
+  *   color:white;
+  * }
+  * 

+  *
+  * @example
+     
+       
+        
+        
+        
+          userType: 
+          Required!

+          userType = {{userType}}

+          myForm.input.$valid = {{myForm.input.$valid}}

+          myForm.input.$error = {{myForm.input.$error}}

+          myForm.$valid = {{myForm.$valid}}

+          myForm.$error.required = {{!!myForm.$error.required}}

+         
+       
+       
+         it('should initialize to model', function() {
+           var userType = element(by.binding('userType'));
+           var valid = element(by.binding('myForm.input.$valid'));
+            expect(userType.getText()).toContain('guest');
+           expect(valid.getText()).toContain('true');
+         });
+          it('should be invalid if empty', function() {

+           var valid = element(by.binding('myForm.input.$valid'));
+           var userInput = element(by.model('userType'));
+            userInput.clear();
+           userInput.sendKeys('');
+            expect(userType.getText()).toEqual('userType =');

-   * @name input[text]
-   *
-   * @description
-   * Standard HTML text input with AngularJS data binding, inherited by most of the `input` elements.
-   *
-   *
-   * @param {string} ngModel Assignable AngularJS expression to data-bind to.
-   * @param {string=} name Property name of the form under which the control is published.
-   * @param {string=} required Adds `required` validation error key if the value is not entered.
-   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
-   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
-   *    `required` when you want to data-bind to the `required` attribute.
-   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
-   *    minlength.
-   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
-   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
-   *    any length.
-   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
-   *    that contains the regular expression body that will be converted to a regular expression
-   *    as in the ngPattern directive.
-   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
-   *    does not match a RegExp found by evaluating the AngularJS expression given in the attribute value.
-   *    If the expression evaluates to a RegExp object, then this is used directly.
-   *    If the expression evaluates to a string, then it will be converted to a RegExp
-   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
-   *    `new RegExp('^abc$')`.

-   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to

+     *
+     * @description
+     * Standard HTML text input with AngularJS data binding, inherited by most of the `input` elements.
+     *
+     *
+     * @param {string} ngModel Assignable AngularJS expression to data-bind to.
+     * @param {string=} name Property name of the form under which the control is published.
+     * @param {string=} required Adds `required` validation error key if the value is not entered.
+     * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
+     *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
+     *    `required` when you want to data-bind to the `required` attribute.
+     * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
+     *    minlength.
+     * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
+     *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
+     *    any length.
+     * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
+     *    that contains the regular expression body that will be converted to a regular expression
+     *    as in the ngPattern directive.
+     * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
+     *    does not match a RegExp found by evaluating the AngularJS expression given in the attribute value.
+     *    If the expression evaluates to a RegExp object, then this is used directly.
+     *    If the expression evaluates to a string, then it will be converted to a RegExp
+     *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
+     *    `new RegExp('^abc$')`.

+     *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
+     *    start at the index of the last search's match, thus not taking the whole input value into
+     *    account.
+     * @param {string=} ngChange AngularJS expression to be executed when input changes due to user
+     *    interaction with the input element.
+     * @param {boolean=} [ngTrim=true] If set to false AngularJS will not automatically trim the input.

-   * ### HTML5 constraint validation and `allowInvalid`
-   *
-   * In browsers that follow the
-   * [HTML5 specification](https://html.spec.whatwg.org/multipage/forms.html#number-state-%28type=number%29),
-   * `input[number]` does not work as expected with {@link ngModelOptions `ngModelOptions.allowInvalid`}.
-   * If a non-number is entered in the input, the browser will report the value as an empty string,
-   * which means the view / model values in `ngModel` and subsequently the scope value
-   * will also be an empty string.
-   *
-   * @knownIssue
-   *
-   * ### Large numbers and `step` validation
-   *
-   * The `step` validation will not work correctly for very large numbers (e.g. 9999999999) due to
-   * Javascript's arithmetic limitations. If you need to handle large numbers, purpose-built
-   * libraries (e.g. https://github.com/MikeMcl/big.js/), can be included into AngularJS by
-   * {@link guide/forms#modifying-built-in-validators overwriting the validators}
-   * for `number` and / or `step`, or by {@link guide/forms#custom-validation applying custom validators}
-   * to an `input[text]` element. The source for `input[number]` type can be used as a starting
-   * point for both implementations.
-   *
-   * @param {string} ngModel Assignable AngularJS expression to data-bind to.
-   * @param {string=} name Property name of the form under which the control is published.
-   * @param {string=} min Sets the `min` validation error key if the value entered is less than `min`.
-   *    Can be interpolated.
-   * @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`.
-   *    Can be interpolated.
-   * @param {string=} ngMin Like `min`, sets the `min` validation error key if the value entered is less than `ngMin`,
-   *    but does not trigger HTML5 native validation. Takes an expression.
-   * @param {string=} ngMax Like `max`, sets the `max` validation error key if the value entered is greater than `ngMax`,
-   *    but does not trigger HTML5 native validation. Takes an expression.
-   * @param {string=} step Sets the `step` validation error key if the value entered does not fit the `step` constraint.
-   *    Can be interpolated.
-   * @param {string=} ngStep Like `step`, sets the `step` validation error key if the value entered does not fit the `ngStep` constraint,
-   *    but does not trigger HTML5 native validation. Takes an expression.
-   * @param {string=} required Sets `required` validation error key if the value is not entered.
-   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
-   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
-   *    `required` when you want to data-bind to the `required` attribute.
-   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
-   *    minlength.
-   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
-   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
-   *    any length.
-   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
-   *    that contains the regular expression body that will be converted to a regular expression
-   *    as in the ngPattern directive.
-   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
-   *    does not match a RegExp found by evaluating the AngularJS expression given in the attribute value.
-   *    If the expression evaluates to a RegExp object, then this is used directly.
-   *    If the expression evaluates to a string, then it will be converted to a RegExp
-   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
-   *    `new RegExp('^abc$')`.

-   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
-   *    start at the index of the last search's match, thus not taking the whole input value into
-   *    account.
-   * @param {string=} ngChange AngularJS expression to be executed when input changes due to user
-   *    interaction with the input element.

-   * @ngdoc input
-   * @name input[url]
-   *
-   * @description
-   * Text input with URL validation. Sets the `url` validation error key if the content is not a
-   * valid URL.
-   *
-   * 

-   * **Note:** `input[url]` uses a regex to validate urls that is derived from the regex
-   * used in Chromium. If you need stricter validation, you can use `ng-pattern` or modify
-   * the built-in validators (see the {@link guide/forms Forms guide})
-   * 

-   *
-   * @param {string} ngModel Assignable AngularJS expression to data-bind to.
-   * @param {string=} name Property name of the form under which the control is published.
-   * @param {string=} required Sets `required` validation error key if the value is not entered.
-   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
-   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
-   *    `required` when you want to data-bind to the `required` attribute.
-   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
-   *    minlength.
-   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
-   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
-   *    any length.
-   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
-   *    that contains the regular expression body that will be converted to a regular expression
-   *    as in the ngPattern directive.
-   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
-   *    does not match a RegExp found by evaluating the AngularJS expression given in the attribute value.
-   *    If the expression evaluates to a RegExp object, then this is used directly.
-   *    If the expression evaluates to a string, then it will be converted to a RegExp
-   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
-   *    `new RegExp('^abc$')`.

-   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
-   *    start at the index of the last search's match, thus not taking the whole input value into
-   *    account.

+     *
+     * In browsers that follow the

+     * `input[number]` does not work as expected with {@link ngModelOptions `ngModelOptions.allowInvalid`}.
+     * If a non-number is entered in the input, the browser will report the value as an empty string,

+     * will also be an empty string.
+     *
+     * @knownIssue
+     *
+     * ### Large numbers and `step` validation
+     *
+     * The `step` validation will not work correctly for very large numbers (e.g. 9999999999) due to
+     * Javascript's arithmetic limitations. If you need to handle large numbers, purpose-built
+     * libraries (e.g. https://github.com/MikeMcl/big.js/), can be included into AngularJS by
+     * {@link guide/forms#modifying-built-in-validators overwriting the validators}
+     * for `number` and / or `step`, or by {@link guide/forms#custom-validation applying custom validators}

-   * @description
-   * HTML radio button.
-   *
-   * **Note:**

-   * All inputs controlled by {@link ngModel ngModel} (including those of type `radio`) will use the
-   * value of their `name` attribute to determine the property under which their
-   * {@link ngModel.NgModelController NgModelController} will be published on the parent
-   * {@link form.FormController FormController}. Thus, if you use the same `name` for multiple
-   * inputs of a form (e.g. a group of radio inputs), only _one_ `NgModelController` will be
-   * published on the parent `FormController` under that name. The rest of the controllers will
-   * continue to work as expected, but you won't be able to access them as properties on the parent
-   * `FormController`.
-   *
-   * 

-   *   

-   *     In plain HTML forms, the `name` attribute is used to identify groups of radio inputs, so
-   *     that the browser can manage their state (checked/unchecked) based on the state of other
-   *     inputs in the same group.
-   *   

-   *   

-   *     In AngularJS forms, this is not necessary. The input's state will be updated based on the
-   *     value of the underlying model data.
-   *   

-   * 

-   *
-   * 

-   *   If you omit the `name` attribute on a radio input, `ngModel` will automatically assign it a
-   *   unique name.
-   *

-   * @ngdoc input
-   * @name input[range]
-   *
-   * @description
-   * Native range input with validation and transformation.
-   *
-   * The model for the range input must always be a `Number`.
-   *
-   * IE9 and other browsers that do not support the `range` type fall back
-   * to a text input without any default values for `min`, `max` and `step`. Model binding,
-   * validation and number parsing are nevertheless supported.
-   *
-   * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]`
-   * in a way that never allows the input to hold an invalid value. That means:
-   * - any non-numerical value is set to `(max + min) / 2`.
-   * - any numerical value that is less than the current min val, or greater than the current max val
-   * is set to the min / max val respectively.
-   * - additionally, the current `step` is respected, so the nearest value that satisfies a step
-   * is used.
-   *
-   * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range))
-   * for more info.
-   *
-   * This has the following consequences for AngularJS:
-   *
-   * Since the element value should always reflect the current model value, a range input
-   * will set the bound ngModel expression to the value that the browser has set for the
-   * input element. For example, in the following input ``,
-   * if the application sets `model.value = null`, the browser will set the input to `'50'`.
-   * AngularJS will then set the model to `50`, to prevent input and model value being out of sync.
-   *
-   * That means the model for range will immediately be set to `50` after `ngModel` has been
-   * initialized. It also means a range input can never have the required error.
-   *
-   * This does not only affect changes to the model value, but also to the values of the `min`,
-   * `max`, and `step` attributes. When these change in a way that will cause the browser to modify
-   * the input value, AngularJS will also update the model value.
-   *
-   * Automatic value adjustment also means that a range input element can never have the `required`,
-   * `min`, or `max` errors.
-   *
-   * However, `step` is currently only fully implemented by Firefox. Other browsers have problems
-   * when the step value changes dynamically - they do not adjust the element value correctly, but
-   * instead may set the `stepMismatch` error. If that's the case, the AngularJS will set the `step`
-   * error on the input, and set the model to `undefined`.
-   *
-   * Note that `input[range]` is not compatible with`ngMax`, `ngMin`, and `ngStep`, because they do
-   * not set the `min` and `max` attributes, which means that the browser won't automatically adjust
-   * the input value based on their values, and will always assume min = 0, max = 100, and step = 1.
-   *
-   * @param {string}  ngModel Assignable AngularJS expression to data-bind to.
-   * @param {string=} name Property name of the form under which the control is published.
-   * @param {string=} min Sets the `min` validation to ensure that the value entered is greater
-   *                  than `min`. Can be interpolated.
-   * @param {string=} max Sets the `max` validation to ensure that the value entered is less than `max`.
-   *                  Can be interpolated.
-   * @param {string=} step Sets the `step` validation to ensure that the value entered matches the `step`
-   *                  Can be interpolated.
-   * @param {expression=} ngChange AngularJS expression to be executed when the ngModel value changes due
-   *                      to user interaction with the input element.
-   * @param {expression=} ngChecked If the expression is truthy, then the `checked` attribute will be set on the
-   *                      element. **Note** : `ngChecked` should not be used alongside `ngModel`.
-   *                      Checkout {@link ng.directive:ngChecked ngChecked} for usage.
-   *
-   * @example
-      
-        
-          
-          

-
-            Model as range:

-            myForm.range.$valid = {{myForm.range.$valid}}

-            myForm.range.$error = {{myForm.range.$error}}

+     * Text input with email validation. Sets the `email` validation error key if not a valid email
+     * address.
+     *
+     * 

+     * **Note:** `input[email]` uses a regex to validate email addresses that is derived from the regex
+     * used in Chromium. If you need stricter validation (e.g. requiring a top-level domain), you can
+     * use `ng-pattern` or modify the built-in validators (see the {@link guide/forms Forms guide})
+     * 

+     *
+     * @param {string} ngModel Assignable AngularJS expression to data-bind to.
+     * @param {string=} name Property name of the form under which the control is published.
+     * @param {string=} required Sets `required` validation error key if the value is not entered.
+     * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
+     *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
+     *    `required` when you want to data-bind to the `required` attribute.
+     * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
+     *    minlength.
+     * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
+     *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
+     *    any length.
+     * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
+     *    that contains the regular expression body that will be converted to a regular expression
+     *    as in the ngPattern directive.
+     * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
+     *    does not match a RegExp found by evaluating the AngularJS expression given in the attribute value.
+     *    If the expression evaluates to a RegExp object, then this is used directly.
+     *    If the expression evaluates to a string, then it will be converted to a RegExp
+     *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
+     *    `new RegExp('^abc$')`.

+     *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
+     *    start at the index of the last search's match, thus not taking the whole input value into
+     *    account.
+     * @param {string=} ngChange AngularJS expression to be executed when input changes due to user

+     * HTML radio button.
+     *
+     * **Note:**

+     * All inputs controlled by {@link ngModel ngModel} (including those of type `radio`) will use the
+     * value of their `name` attribute to determine the property under which their
+     * {@link ngModel.NgModelController NgModelController} will be published on the parent
+     * {@link form.FormController FormController}. Thus, if you use the same `name` for multiple
+     * inputs of a form (e.g. a group of radio inputs), only _one_ `NgModelController` will be
+     * published on the parent `FormController` under that name. The rest of the controllers will
+     * continue to work as expected, but you won't be able to access them as properties on the parent
+     * `FormController`.
+     *
+     * 

+     *   

+     *     In plain HTML forms, the `name` attribute is used to identify groups of radio inputs, so
+     *     that the browser can manage their state (checked/unchecked) based on the state of other
+     *     inputs in the same group.
+     *   

+     *   

+     *     In AngularJS forms, this is not necessary. The input's state will be updated based on the
+     *     value of the underlying model data.
+     *   

+     * 

+     *
+     * 

+     *   If you omit the `name` attribute on a radio input, `ngModel` will automatically assign it a
+     *   unique name.
+     * 

+     *
+     * @param {string} ngModel Assignable AngularJS expression to data-bind to.
+     * @param {string} value The value to which the `ngModel` expression should be set when selected.
+     *    Note that `value` only supports `string` values, i.e. the scope model needs to be a string,
+     *    too. Use `ngValue` if you need complex models (`number`, `object`, ...).
+     * @param {string=} name Property name of the form under which the control is published.
+     * @param {string=} ngChange AngularJS expression to be executed when input changes due to user
+     *    interaction with the input element.
+     * @param {string} ngValue AngularJS expression to which `ngModel` will be be set when the radio
+     *    is selected. Should be used instead of the `value` attribute if you need
+     *    a non-string `ngModel` (`boolean`, `array`, ...).
+     *
+     * @example
+        
+

+            

+            Note that `ng-value="specialValue"` sets radio item's value to be the value of `$scope.specialValue`.

+     * @name input[range]
+     *
+     * @description
+     * Native range input with validation and transformation.
+     *
+     * The model for the range input must always be a `Number`.
+     *
+     * IE9 and other browsers that do not support the `range` type fall back
+     * to a text input without any default values for `min`, `max` and `step`. Model binding,
+     * validation and number parsing are nevertheless supported.
+     *
+     * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]`
+     * in a way that never allows the input to hold an invalid value. That means:
+     * - any non-numerical value is set to `(max + min) / 2`.
+     * - any numerical value that is less than the current min val, or greater than the current max val
+     * is set to the min / max val respectively.
+     * - additionally, the current `step` is respected, so the nearest value that satisfies a step
+     * is used.
+     *
+     * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range))
+     * for more info.
+     *
+     * This has the following consequences for AngularJS:
+     *
+     * Since the element value should always reflect the current model value, a range input
+     * will set the bound ngModel expression to the value that the browser has set for the
+     * input element. For example, in the following input ``,
+     * if the application sets `model.value = null`, the browser will set the input to `'50'`.
+     * AngularJS will then set the model to `50`, to prevent input and model value being out of sync.
+     *
+     * That means the model for range will immediately be set to `50` after `ngModel` has been
+     * initialized. It also means a range input can never have the required error.
+     *
+     * This does not only affect changes to the model value, but also to the values of the `min`,
+     * `max`, and `step` attributes. When these change in a way that will cause the browser to modify
+     * the input value, AngularJS will also update the model value.
+     *
+     * Automatic value adjustment also means that a range input element can never have the `required`,
+     * `min`, or `max` errors.
+     *
+     * However, `step` is currently only fully implemented by Firefox. Other browsers have problems
+     * when the step value changes dynamically - they do not adjust the element value correctly, but
+     * instead may set the `stepMismatch` error. If that's the case, the AngularJS will set the `step`
+     * error on the input, and set the model to `undefined`.
+     *
+     * Note that `input[range]` is not compatible with`ngMax`, `ngMin`, and `ngStep`, because they do
+     * not set the `min` and `max` attributes, which means that the browser won't automatically adjust
+     * the input value based on their values, and will always assume min = 0, max = 100, and step = 1.
+     *
+     * @param {string}  ngModel Assignable AngularJS expression to data-bind to.
+     * @param {string=} name Property name of the form under which the control is published.
+     * @param {string=} min Sets the `min` validation to ensure that the value entered is greater
+     *                  than `min`. Can be interpolated.
+     * @param {string=} max Sets the `max` validation to ensure that the value entered is less than `max`.
+     *                  Can be interpolated.
+     * @param {string=} step Sets the `step` validation to ensure that the value entered matches the `step`

+     *                      element. **Note** : `ngChecked` should not be used alongside `ngModel`.
+     *                      Checkout {@link ng.directive:ngChecked ngChecked} for usage.
+     *

- *
- * @description
- * HTML textarea element control with AngularJS data-binding. The data-binding and validation
- * properties of this element are exactly the same as those of the
- * {@link ng.directive:input input element}.
- *
- * @param {string} ngModel Assignable AngularJS expression to data-bind to.
- * @param {string=} name Property name of the form under which the control is published.
- * @param {string=} required Sets `required` validation error key if the value is not entered.
- * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
- *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
- *    `required` when you want to data-bind to the `required` attribute.
- * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
- *    minlength.
- * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
- *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of any
- *    length.
- * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
- *    does not match a RegExp found by evaluating the AngularJS expression given in the attribute value.
- *    If the expression evaluates to a RegExp object, then this is used directly.
- *    If the expression evaluates to a string, then it will be converted to a RegExp
- *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
- *    `new RegExp('^abc$')`.

- *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
- *    start at the index of the last search's match, thus not taking the whole input value into
- *    account.
- * @param {string=} ngChange AngularJS expression to be executed when input changes due to user
- *    interaction with the input element.
- * @param {boolean=} [ngTrim=true] If set to false AngularJS will not automatically trim the input.

- * @property {*} $viewValue The actual value from the control's view. For `input` elements, this is a
- * String. See {@link ngModel.NgModelController#$setViewValue} for information about when the $viewValue
- * is set.
- *
- * @property {*} $modelValue The value in the model that the control is bound to.
- *
- * @property {Array.} $parsers Array of functions to execute, as a pipeline, whenever
- *  the control updates the ngModelController with a new {@link ngModel.NgModelController#$viewValue
-    `$viewValue`} from the DOM, usually via user input.
-    See {@link ngModel.NgModelController#$setViewValue `$setViewValue()`} for a detailed lifecycle explanation.
-    Note that the `$parsers` are not called when the bound ngModel expression changes programmatically.
-
-  The functions are called in array order, each passing
-    its return value through to the next. The last return value is forwarded to the
-    {@link ngModel.NgModelController#$validators `$validators`} collection.
-
-  Parsers are used to sanitize / convert the {@link ngModel.NgModelController#$viewValue
-    `$viewValue`}.
-
-  Returning `undefined` from a parser means a parse error occurred. In that case,
-    no {@link ngModel.NgModelController#$validators `$validators`} will run and the `ngModel`
-    will be set to `undefined` unless {@link ngModelOptions `ngModelOptions.allowInvalid`}
-    is set to `true`. The parse error is stored in `ngModel.$error.parse`.
-
-  This simple example shows a parser that would convert text input value to lowercase:
- * ```js
- * function parse(value) {
- *   if (value) {
- *     return value.toLowerCase();
- *   }
- * }
- * ngModelController.$parsers.push(parse);

- *
- * @property {Array.} $formatters Array of functions to execute, as a pipeline, whenever
-    the bound ngModel expression changes programmatically. The `$formatters` are not called when the
-    value of the control is changed by user interaction.
-
-  Formatters are used to format / convert the {@link ngModel.NgModelController#$modelValue
-    `$modelValue`} for display in the control.
-
-  The functions are called in reverse array order, each passing the value through to the
-    next. The last return value is used as the actual DOM value.
-
-  This simple example shows a formatter that would convert the model value to uppercase:
-
- * ```js
- * function format(value) {
- *   if (value) {
- *     return value.toUpperCase();
- *   }
- * }
- * ngModel.$formatters.push(format);
- * ```
- *
- * @property {Object.} $validators A collection of validators that are applied
- *      whenever the model value changes. The key value within the object refers to the name of the
- *      validator while the function refers to the validation operation. The validation operation is
- *      provided with the model value as an argument and must return a true or false value depending
- *      on the response of that validation.
- *
- * ```js
- * ngModel.$validators.validCharacters = function(modelValue, viewValue) {
- *   var value = modelValue || viewValue;
- *   return /[0-9]+/.test(value) &&
- *          /[a-z]+/.test(value) &&
- *          /[A-Z]+/.test(value) &&
- *          /\W+/.test(value);
- * };
- * ```
- *
- * @property {Object.} $asyncValidators A collection of validations that are expected to
- *      perform an asynchronous validation (e.g. a HTTP request). The validation function that is provided
- *      is expected to return a promise when it is run during the model validation process. Once the promise
- *      is delivered then the validation status will be set to true when fulfilled and false when rejected.
- *      When the asynchronous validators are triggered, each of the validators will run in parallel and the model
- *      value will only be updated once all validators have been fulfilled. As long as an asynchronous validator
- *      is unfulfilled, its key will be added to the controllers `$pending` property. Also, all asynchronous validators
- *      will only run once all synchronous validators have passed.
- *
- * Please note that if $http is used then it is important that the server returns a success HTTP response code
- * in order to fulfill the validation and a status level of `4xx` in order to reject the validation.
- *
- * ```js
- * ngModel.$asyncValidators.uniqueUsername = function(modelValue, viewValue) {
- *   var value = modelValue || viewValue;
- *
- *   // Lookup user by username
- *   return $http.get('/api/users/' + value).
- *      then(function resolved() {
- *        //username exists, this means validation fails
- *        return $q.reject('exists');
- *      }, function rejected() {
- *        //username does not exist, therefore this validation passes
- *        return true;
- *      });
- * };
- * ```
- *
- * @property {Array.} $viewChangeListeners Array of functions to execute whenever
- *     a change to {@link ngModel.NgModelController#$viewValue `$viewValue`} has caused a change
- *     to {@link ngModel.NgModelController#$modelValue `$modelValue`}.
- *     It is called with no arguments, and its return value is ignored.
- *     This can be used in place of additional $watches against the model value.
- *
- * @property {Object} $error An object hash with all failing validator ids as keys.
- * @property {Object} $pending An object hash with all pending validator ids as keys.
- *
- * @property {boolean} $untouched True if control has not lost focus yet.
- * @property {boolean} $touched True if control has lost focus.
- * @property {boolean} $pristine True if user has not interacted with the control yet.
- * @property {boolean} $dirty True if user has already interacted with the control.
- * @property {boolean} $valid True if there is no error.
- * @property {boolean} $invalid True if at least one error on the control.
- * @property {string} $name The name attribute of the control.
- *
- * @description
- *
- * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
- * The controller contains services for data-binding, validation, CSS updates, and value formatting
- * and parsing. It purposefully does not contain any logic which deals with DOM rendering or
- * listening to DOM events.
- * Such DOM related logic should be provided by other directives which make use of
- * `NgModelController` for data-binding to control elements.
- * AngularJS provides this DOM logic for most {@link input `input`} elements.
- * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
- * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
- *
- * @example
- * ### Custom Control Example
- * This example shows how to use `NgModelController` with a custom control to achieve
- * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
- * collaborate together to achieve the desired result.
- *
- * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
- * contents be edited in place by the user.
- *
- * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
- * module to automatically remove "bad" content like inline event listener (e.g. ``).
- * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
- * that content using the `$sce` service.
- *
- * 
-    
-      [contenteditable] {
-        border: 1px solid black;
-        background-color: white;
-        min-height: 20px;

-   * @ngdoc method
-   * @name ngModel.NgModelController#$render
+   * @ngdoc directive
+   * @name ngInit
+   * @restrict AC
+   * @priority 450
+   * @element ANY
+   *
+   * @param {expression} ngInit {@link guide/expression Expression} to eval.
    *
    * @description
-   * Called when the view needs to be updated. It is expected that the user of the ng-model
-   * directive will implement this method.
+   * The `ngInit` directive allows you to evaluate an expression in the
+   * current scope.
    *
-   * The `$render()` method is invoked in the following situations:
+   * 

+   * This directive can be abused to add unnecessary amounts of logic into your templates.
+   * There are only a few appropriate uses of `ngInit`:
+   * 
    
+   *   
  • aliasing special properties of {@link ng.directive:ngRepeat `ngRepeat`},
+   *     as seen in the demo below.
    • 
+   *   
  • initializing data during development, or for examples, as seen throughout these docs.
    • 
+   *   
  • injecting data via server side scripting.
    • 
+   * 

+   *
+   * Besides these few cases, you should use {@link guide/component Components} or
+   * {@link guide/controller Controllers} rather than `ngInit` to initialize values on a scope.
+   * 

    *
-   * * `$rollbackViewValue()` is called.  If we are rolling back the view value to the last
-   *   committed value then `$render()` is called to update the input control.
-   * * The value referenced by `ng-model` is changed programmatically and both the `$modelValue` and
-   *   the `$viewValue` are different from last time.
+   * 

+   * **Note**: If you have assignment in `ngInit` along with a {@link ng.$filter `filter`}, make
+   * sure you have parentheses to ensure correct operator precedence:
+   * 
+   * `
`
+   * 

+   * 

    *
-   * Since `ng-model` does not do a deep watch, `$render()` is only invoked if the values of
-   * `$modelValue` and `$viewValue` are actually different from their previous values. If `$modelValue`
-   * or `$viewValue` are objects (rather than a string or number) then `$render()` will not be
-   * invoked if you only change a property on the objects.
+   * @example
+     
+       
+     
+     

+       

+         

+            list[ {{outerIndex}} ][ {{innerIndex}} ] = {{value}};

-   * @ngdoc method

+   * @name ngList
+   * @restrict A
+   * @priority 100
+   *
+   * @param {string=} ngList optional delimiter that should be used to split the value.
    *
    * @description
-   * This is called when we need to determine if the value of an input is empty.
+   * Text input that converts between a delimited string and an array of strings. The default
+   * delimiter is a comma followed by a space - equivalent to `ng-list=", "`. You can specify a custom
+   * delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`.
+   *
+   * The behaviour of the directive is affected by the use of the `ngTrim` attribute.
+   * * If `ngTrim` is set to `"false"` then whitespace around both the separator and each
+   *   list item is respected. This implies that the user of the directive is responsible for
+   *   dealing with whitespace but also allows you to use whitespace as a delimiter, such as a
+   *   tab or newline character.
+   * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected
+   *   when joining the list items back together) and whitespace around each list item is stripped
+   *   before it is added to the model.
+   *
+   * @example
+   * ### Validation
    *
-   * For instance, the required directive does this to work out if the input has data or not.
+   * 
+   *   
+   *      angular.module('listExample', [])
+   *        .controller('ExampleController', ['$scope', function($scope) {

+   *        
+   *        Required!
+   *      
+   *      

+   *      names = {{names}}

+   *      myForm.namesInput.$valid = {{myForm.namesInput.$valid}}

+   *      myForm.namesInput.$error = {{myForm.namesInput.$error}}

+   *      myForm.$valid = {{myForm.$valid}}

+   *      myForm.$error.required = {{!!myForm.$error.required}}

+   *     

+   *   
+   *   
+   *     var listInput = element(by.model('names'));
+   *     var names = element(by.exactBinding('names'));
+   *     var valid = element(by.binding('myForm.namesInput.$valid'));
+   *     var error = element(by.css('span.error'));
+   *
+   *     it('should initialize to model', function() {
+   *       expect(names.getText()).toContain('["morpheus","neo","trinity"]');
+   *       expect(valid.getText()).toContain('true');
+   *       expect(error.getCssValue('display')).toBe('none');
+   *     });
+   *
+   *     it('should be invalid if empty', function() {
+   *       listInput.clear();
+   *       listInput.sendKeys('');
+   *
+   *       expect(names.getText()).toContain('');
+   *       expect(valid.getText()).toContain('false');
+   *       expect(error.getCssValue('display')).not.toBe('none');
+   *     });
+   *   
+   * 
    *
-   * The default `$isEmpty` function checks whether the value is `undefined`, `''`, `null` or `NaN`.
+   * @example
+   * ### Splitting on newline
    *
-   * You can override this for input directives whose concept of being empty is different from the
-   * default. The `checkboxInputType` directive does this because in its case a value of `false`
-   * implies empty.

+      See {@link ngModel.NgModelController#$setViewValue `$setViewValue()`} for a detailed lifecycle explanation.
+      Note that the `$parsers` are not called when the bound ngModel expression changes programmatically.
+  
+    The functions are called in array order, each passing

+  
+    Returning `undefined` from a parser means a parse error occurred. In that case,

+   * listening to DOM events.
+   * Such DOM related logic should be provided by other directives which make use of
+   * `NgModelController` for data-binding to control elements.
+   * AngularJS provides this DOM logic for most {@link input `input`} elements.
+   * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
+   * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.

+   * ### Custom Control Example
+   * This example shows how to use `NgModelController` with a custom control to achieve
+   * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
+   * collaborate together to achieve the desired result.
+   *
+   * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
+   * contents be edited in place by the user.
+   *
+   * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
+   * module to automatically remove "bad" content like inline event listener (e.g. ``).
+   * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
+   * that content using the `$sce` service.
+   *
+   * 
+      
+        [contenteditable] {
+          border: 1px solid black;
+          background-color: white;
+          min-height: 20px;
+        }
+  
+        .ng-invalid {
+          border: 1px solid red;
+        }
+  
+      
+      
+        angular.module('customControl', ['ngSanitize']).
+          directive('contenteditable', ['$sce', function($sce) {
+            return {
+              restrict: 'A', // only activate on element attribute
+              require: '?ngModel', // get a hold of NgModelController
+              link: function(scope, element, attrs, ngModel) {
+                if (!ngModel) return; // do nothing if no ng-model
+

+                ngModel.$render = function() {
+                  element.html($sce.getTrustedHtml(ngModel.$viewValue || ''));
+                };

+                // Listen for change events to enable binding
+                element.on('blur keyup change', function() {

 behind
+                  // If strip-br attribute is provided then we strip this out
+                  if (attrs.stripBr && html === '
') {
+                    html = '';
+                  }
+                  ngModel.$setViewValue(html);

Both of these inputs are only updated if they are blurred. Hitting escape should
-   *       empty them. Follow these steps and observe the difference:

-   *       
    
-   *         
  1. Type something in the input. You will see that the model is not yet updated
    2. 
-   *         
  2. Press the Escape key.
-   *           
      
-   *             
    1.  In the first example, nothing happens, because the model is already '', and no
-   *             update is detected. If you blur the input, the model will be set to the current view.
-   *             
      2. 
-   *             
    2.  In the second example, the pending update is cancelled, and the input is set back
-   *             to the last committed view value (''). Blurring the input does nothing.
-   *             
      3. 
-   *

+     *
+     * @description
+     * Cancel an update and reset the input element's value to prevent an update to the `$modelValue`,
+     * which may be caused by a pending debounced event or because the input is waiting for some
+     * future event.
+     *
+     * If you have an input that uses `ng-model-options` to set up debounced updates or updates that
+     * depend on special events such as `blur`, there can be a period when the `$viewValue` is out of
+     * sync with the ngModel's `$modelValue`.
+     *
+     * In this case, you can use `$rollbackViewValue()` to manually cancel the debounced / future update
+     * and reset the input to the last committed view value.
+     *
+     * It is also possible that you run into difficulties if you try to update the ngModel's `$modelValue`
+     * programmatically before these debounced/future events have resolved/occurred, because AngularJS's
+     * dirty checking mechanism is not able to tell whether the model has actually changed or not.
+     *
+     * The `$rollbackViewValue()` method should be called before programmatically changing the model of an
+     * input which may have such events pending. This is important in order to make sure that the
+     * input field will be updated with the new model value and any pending operations are cancelled.
+     *
+     * @example
+     * 
+     *   
+     *     angular.module('cancel-update-example', [])
+     *
+     *     .controller('CancelUpdateController', ['$scope', function($scope) {
+     *       $scope.model = {value1: '', value2: ''};
+     *
+     *       $scope.setEmpty = function(e, value, rollback) {
+     *         if (e.keyCode === 27) {
+     *           e.preventDefault();
+     *           if (rollback) {
+     *             $scope.myForm[value].$rollbackViewValue();
+     *           }
+     *           $scope.model[value] = '';
+     *         }
+     *       };
+     *     }]);
+     *   
+     *   
+     *     

+     *       
Both of these inputs are only updated if they are blurred. Hitting escape should
+     *       empty them. Follow these steps and observe the difference:

+     *       
    
+     *         
  1. Type something in the input. You will see that the model is not yet updated
    2. 
+     *         
  2. Press the Escape key.
+     *           
      
+     *             
    1.  In the first example, nothing happens, because the model is already '', and no
+     *             update is detected. If you blur the input, the model will be set to the current view.
+     *             
      2. 
+     *             
    2.  In the second example, the pending update is cancelled, and the input is set back
+     *             to the last committed view value (''). Blurring the input does nothing.
+     *             
      3.

+     *
+     * When `$setViewValue` is called, the new `value` will be staged for committing through the `$parsers`
+     * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
+     * value is sent directly for processing through the `$parsers` pipeline. After this, the `$validators` and
+     * `$asyncValidators` are called and the value is applied to `$modelValue`.
+     * Finally, the value is set to the **expression** specified in the `ng-model` attribute and
+     * all the registered change listeners, in the `$viewChangeListeners` list are called.
+     *
+     * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
+     * and the `default` trigger is not listed, all those actions will remain pending until one of the
+     * `updateOn` events is triggered on the DOM element.
+     * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
+     * directive is used with a custom debounce for this particular event.
+     * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`
+     * is specified, once the timer runs out.
+     *
+     * When used with standard inputs, the view value will always be a string (which is in some cases
+     * parsed into another type, such as a `Date` object for `input[date]`.)
+     * However, custom controls might also pass objects to this method. In this case, we should make
+     * a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not
+     * perform a deep watch of objects, it only looks for a change of identity. If you only change
+     * the property of the object then ngModel will not realize that the object has changed and
+     * will not invoke the `$parsers` and `$validators` pipelines. For this reason, you should
+     * not change properties of the copy once it has been passed to `$setViewValue`.
+     * Otherwise you may cause the model value on the scope to change incorrectly.
+     *
+     * 

+     * In any case, the value passed to the method should always reflect the current value
+     * of the control. For example, if you are calling `$setViewValue` for an input element,
+     * you should pass the input DOM value. Otherwise, the control and the scope model become

+     * the control's DOM value in any way. If we want to change the control's DOM value
+     * programmatically, we should update the `ngModel` scope expression. Its new value will be

+     * Runs the model -> view pipeline on the current

+     * and the result is set to the {@link ngModel.NgModelController#$viewValue $viewValue}
+     * - the `ng-empty` or `ng-not-empty` class is set on the element
+     * - if the `$viewValue` has changed:
+     *   - {@link ngModel.NgModelController#$render $render} is called on the control
+     *   - the {@link ngModel.NgModelController#$validators $validators} are run and
+     *   the validation status is set.
+     *
+     * This method is called by ngModel internally when the bound scope value changes.
+     * Application developers usually do not have to call this function themselves.
+     *
+     * This function can be used when the `$viewValue` or the rendered DOM value are not correctly
+     * formatted and the `$modelValue` must be run through the `$formatters` again.
+     *
+     * @example
+     * Consider a text input with an autocomplete list (for fruit), where the items are
+     * objects with a name and an id.
+     * A user enters `ap` and then selects `Apricot` from the list.
+     * Based on this, the autocomplete widget will call `$setViewValue({name: 'Apricot', id: 443})`,
+     * but the rendered value will still be `ap`.
+     * The widget can then call `ctrl.$processModelValue()` to run the model -> view
+     * pipeline again, which formats the object to the string `Apricot`,
+     * then updates the `$viewValue`, and finally renders it in the DOM.

   /**
-   * @ngdoc method
-   *
-   * @name ngModel.NgModelController#$overrideModelOptions
+   * @ngdoc directive
+   * @name ngModel
+   * @restrict A
+   * @priority 1
+   * @param {expression} ngModel assignable {@link guide/expression Expression} to bind to.
    *
    * @description
+   * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a
+   * property on the scope using {@link ngModel.NgModelController NgModelController},
+   * which is created and exposed by this directive.
+   *
+   * `ngModel` is responsible for:
+   *
+   * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
+   *   require.
+   * - Providing validation behavior (i.e. required, number, email, url).
+   * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
+   * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`,
+   *   `ng-untouched`, `ng-empty`, `ng-not-empty`) including animations.
+   * - Registering the control with its parent {@link ng.directive:form form}.
+   *
+   * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
+   * current scope. If the property doesn't already exist on this scope, it will be created
+   * implicitly and added to the scope.
+   *
+   * For best practices on using `ngModel`, see:
+   *
+   *  - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)
+   *
+   * For basic examples, how to use `ngModel`, see:
+   *
+   *  - {@link ng.directive:input input}
+   *    - {@link input[text] text}
+   *    - {@link input[checkbox] checkbox}
+   *    - {@link input[radio] radio}
+   *    - {@link input[number] number}
+   *    - {@link input[email] email}
+   *    - {@link input[url] url}
+   *    - {@link input[date] date}
+   *    - {@link input[datetime-local] datetime-local}
+   *    - {@link input[time] time}
+   *    - {@link input[month] month}
+   *    - {@link input[week] week}
+   *  - {@link ng.directive:select select}
+   *  - {@link ng.directive:textarea textarea}
+   *
+   * ## Complex Models (objects or collections)
+   *
+   * By default, `ngModel` watches the model by reference, not value. This is important to know when
+   * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the
+   * object or collection change, `ngModel` will not be notified and so the input will not be  re-rendered.
+   *
+   * The model must be assigned an entirely new object or collection before a re-rendering will occur.
+   *
+   * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression
+   * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or
+   * if the select is given the `multiple` attribute.
+   *
+   * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the
+   * first level of the object (or only changing the properties of an item in the collection if it's an array) will still
+   * not trigger a re-rendering of the model.
+   *
+   * ## CSS classes
+   * The following CSS classes are added and removed on the associated input/select/textarea element
+   * depending on the validity of the model.
+   *
+   *  - `ng-valid`: the model is valid
+   *  - `ng-invalid`: the model is invalid
+   *  - `ng-valid-[key]`: for each valid key added by `$setValidity`
+   *  - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
+   *  - `ng-pristine`: the control hasn't been interacted with yet
+   *  - `ng-dirty`: the control has been interacted with
+   *  - `ng-touched`: the control has been blurred
+   *  - `ng-untouched`: the control hasn't been blurred
+   *  - `ng-pending`: any `$asyncValidators` are unfulfilled
+   *  - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined
+   *     by the {@link ngModel.NgModelController#$isEmpty} method
+   *  - `ng-not-empty`: the view contains a non-empty value
+   *
+   * Keep in mind that ngAnimate can detect each of these classes when added and removed.
+   *
+   * @animations
+   * Animations within models are triggered when any of the associated CSS classes are added and removed
+   * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,
+   * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
+   * The animations that are triggered within ngModel are similar to how they work in ngClass and
+   * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
+   *
+   * The following example shows a simple way to utilize CSS transitions to style an input element
+   * that has been rendered as invalid after it has been validated:
    *
-   * Override the current model options settings programmatically.
+   * 
+   * //be sure to include ngAnimate as a module to hook into more
+   * //advanced animations
+   * .my-input {
+   *   transition:0.5s linear all;
+   *   background: white;
+   * }
+   * .my-input.ng-invalid {
+   *   background: red;
+   *   color:white;
+   * }
+   * 

    *
-   * The previous `ModelOptions` value will not be modified. Instead, a
-   * new `ModelOptions` object will inherit from the previous one overriding
-   * or inheriting settings that are defined in the given parameter.
+   * @example
+   * ### Basic Usage
+   * 
+       
+         
+         
+         

+          Update input to see transitions when valid/invalid.
+          Integer is a valid value.
+         

+         

+           
+         

+       
+   * 
    *
-   * See {@link ngModelOptions} for information about what options can be specified
-   * and how model option inheritance works.
+   * @example
+   * ### Binding to a getter/setter
    *
-   * 

-   * **Note:** this function only affects the options set on the `ngModelController`,
-   * and not the options on the {@link ngModelOptions} directive from which they might have been
-   * obtained initially.
-   * 

+   * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a
+   * function that returns a representation of the model when called with zero arguments, and sets
+   * the internal state of a model when called with an argument. It's sometimes useful to use this
+   * for models that have an internal representation that's different from what the model exposes
+   * to the view.
    *
-   * 

-   * **Note:** it is not possible to override the `getterSetter` option.
+   * 

+   * **Best Practice:** It's best to keep getters fast because AngularJS is likely to call them more
+   * frequently than other parts of your code.
    * 

    *
-   * @param {Object} options a hash of settings to override the previous options
-   *

-  /**
-   * @ngdoc method
-   *
-   * @name  ngModel.NgModelController#$processModelValue
-
-   * @description
-   *
-   * Runs the model -> view pipeline on the current
-   * {@link ngModel.NgModelController#$modelValue $modelValue}.
+   * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
+   * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
+   * a `
`, which will enable this behavior for all ``s within it. See
+   * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
    *
-   * The following actions are performed by this method:
-   *
-   * - the `$modelValue` is run through the {@link ngModel.NgModelController#$formatters $formatters}
-   * and the result is set to the {@link ngModel.NgModelController#$viewValue $viewValue}
-   * - the `ng-empty` or `ng-not-empty` class is set on the element
-   * - if the `$viewValue` has changed:
-   *   - {@link ngModel.NgModelController#$render $render} is called on the control
-   *   - the {@link ngModel.NgModelController#$validators $validators} are run and
-   *   the validation status is set.
-   *
-   * This method is called by ngModel internally when the bound scope value changes.
-   * Application developers usually do not have to call this function themselves.
-   *
-   * This function can be used when the `$viewValue` or the rendered DOM value are not correctly
-   * formatted and the `$modelValue` must be run through the `$formatters` again.
+   * The following example shows how to use `ngModel` with a getter/setter:
    *
    * @example
-   * Consider a text input with an autocomplete list (for fruit), where the items are
-   * objects with a name and an id.
-   * A user enters `ap` and then selects `Apricot` from the list.
-   * Based on this, the autocomplete widget will call `$setViewValue({name: 'Apricot', id: 443})`,
-   * but the rendered value will still be `ap`.
-   * The widget can then call `ctrl.$processModelValue()` to run the model -> view
-   * pipeline again, which formats the object to the string `Apricot`,
-   * then updates the `$viewValue`, and finally renders it in the DOM.
-   *
-   *

- * - Providing validation behavior (i.e. required, number, email, url).
- * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
- * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`,
- *   `ng-untouched`, `ng-empty`, `ng-not-empty`) including animations.
- * - Registering the control with its parent {@link ng.directive:form form}.
- *
- * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
- * current scope. If the property doesn't already exist on this scope, it will be created
- * implicitly and added to the scope.
- *
- * For best practices on using `ngModel`, see:
- *
- *  - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)
- *
- * For basic examples, how to use `ngModel`, see:
- *
- *  - {@link ng.directive:input input}
- *    - {@link input[text] text}
- *    - {@link input[checkbox] checkbox}
- *    - {@link input[radio] radio}
- *    - {@link input[number] number}
- *    - {@link input[email] email}
- *    - {@link input[url] url}
- *    - {@link input[date] date}
- *    - {@link input[datetime-local] datetime-local}
- *    - {@link input[time] time}
- *    - {@link input[month] month}
- *    - {@link input[week] week}
- *  - {@link ng.directive:select select}
- *  - {@link ng.directive:textarea textarea}
- *
- * ## Complex Models (objects or collections)
- *
- * By default, `ngModel` watches the model by reference, not value. This is important to know when
- * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the
- * object or collection change, `ngModel` will not be notified and so the input will not be  re-rendered.
- *
- * The model must be assigned an entirely new object or collection before a re-rendering will occur.
- *
- * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression
- * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or
- * if the select is given the `multiple` attribute.
- *
- * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the
- * first level of the object (or only changing the properties of an item in the collection if it's an array) will still
- * not trigger a re-rendering of the model.
- *
- * ## CSS classes
- * The following CSS classes are added and removed on the associated input/select/textarea element
- * depending on the validity of the model.
- *
- *  - `ng-valid`: the model is valid
- *  - `ng-invalid`: the model is invalid
- *  - `ng-valid-[key]`: for each valid key added by `$setValidity`
- *  - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
- *  - `ng-pristine`: the control hasn't been interacted with yet
- *  - `ng-dirty`: the control has been interacted with
- *  - `ng-touched`: the control has been blurred
- *  - `ng-untouched`: the control hasn't been blurred
- *  - `ng-pending`: any `$asyncValidators` are unfulfilled
- *  - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined
- *     by the {@link ngModel.NgModelController#$isEmpty} method
- *  - `ng-not-empty`: the view contains a non-empty value
- *
- * Keep in mind that ngAnimate can detect each of these classes when added and removed.
- *
- * @animations
- * Animations within models are triggered when any of the associated CSS classes are added and removed
- * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,
- * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
- * The animations that are triggered within ngModel are similar to how they work in ngClass and
- * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
- *
- * The following example shows a simple way to utilize CSS transitions to style an input element
- * that has been rendered as invalid after it has been validated:
- *
- * 
- * //be sure to include ngAnimate as a module to hook into more
- * //advanced animations
- * .my-input {
- *   transition:0.5s linear all;
- *   background: white;
- * }
- * .my-input.ng-invalid {
- *   background: red;
- *   color:white;
- * }
- * 

- *
- * @example
- * ### Basic Usage
- * 
-     
-       
-       
-       

-        Update input to see transitions when valid/invalid.
-        Integer is a valid value.
-       

-       

-         
-       

-     
- * 
- *
- * @example
- * ### Binding to a getter/setter
- *
- * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a
- * function that returns a representation of the model when called with zero arguments, and sets
- * the internal state of a model when called with an argument. It's sometimes useful to use this
- * for models that have an internal representation that's different from what the model exposes
- * to the view.
- *
- * 

- * **Best Practice:** It's best to keep getters fast because AngularJS is likely to call them more
- * frequently than other parts of your code.
- * 

- *
- * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
- * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
- * a `
`, which will enable this behavior for all ``s within it. See
- * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
- *
- * The following example shows how to use `ngModel` with a getter/setter:
- *
- * @example
- * 
-     
-       

-         
-           
-         
-         
user.name = 

-       

-     
-     
-       angular.module('getterSetterExample', [])
-         .controller('ExampleController', ['$scope', function($scope) {
-           var _name = 'Brian';
-           $scope.user = {
-             name: function(newName) {
-              // Note that newName can be undefined for two reasons:
-              // 1. Because it is called as a getter and thus called with no arguments
-              // 2. Because the property should actually be set to undefined. This happens e.g. if the
-              //    input is invalid
-              return arguments.length ? (_name = newName) : _name;
-             }
-           };
-         }]);
-     
- *

-/**
- * @ngdoc directive
- * @name ngModelOptions
- * @restrict A
- * @priority 10
- *
- * @description
- * This directive allows you to modify the behaviour of {@link ngModel} directives within your
- * application. You can specify an `ngModelOptions` directive on any element. All {@link ngModel}
- * directives will use the options of their nearest `ngModelOptions` ancestor.
- *
- * The `ngModelOptions` settings are found by evaluating the value of the attribute directive as
- * an AngularJS expression. This expression should evaluate to an object, whose properties contain
- * the settings. For example: `

- *   

- *     
- *   

- * 

- * ```
- *
- * the `input` element will have the following settings
- *
- * ```js
- * { allowInvalid: true, updateOn: 'default', debounce: 0 }
- * ```
- *
- * Notice that the `debounce` setting was not inherited and used the default value instead.
- *
- * You can specify that all undefined settings are automatically inherited from an ancestor by
- * including a property with key of `"*"` and value of `"$inherit"`.
- *
- * For example given the following fragment of HTML
- *
- *
- * ```html
- * 

- *   

- *     
- *   

- * 

- * ```
- *
- * the `input` element will have the following settings
- *
- * ```js
- * { allowInvalid: true, updateOn: 'default', debounce: 200 }
- * ```
- *
- * Notice that the `debounce` setting now inherits the value from the outer `
` element.
- *
- * If you are creating a reusable component then you should be careful when using `"*": "$inherit"`
- * since you may inadvertently inherit a setting in the future that changes the behavior of your component.
- *
- *
- * ## Triggering and debouncing model updates
- *
- * The `updateOn` and `debounce` properties allow you to specify a custom list of events that will
- * trigger a model update and/or a debouncing delay so that the actual update only takes place when
- * a timer expires; this timer will be reset after another change takes place.
- *
- * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
- * be different from the value in the actual model. This means that if you update the model you
- * should also invoke {@link ngModel.NgModelController#$rollbackViewValue} on the relevant input field in
- * order to make sure it is synchronized with the model and that any debounced action is canceled.
- *
- * The easiest way to reference the control's {@link ngModel.NgModelController#$rollbackViewValue}
- * method is by making sure the input is placed inside a form that has a `name` attribute. This is
- * important because `form` controllers are published to the related scope under the name in their
- * `name` attribute.
- *
- * Any pending changes will take place immediately when an enclosing form is submitted via the
- * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
- * to have access to the updated model.
- *
- * ### Overriding immediate updates
- *
- * The following example shows how to override immediate updates. Changes on the inputs within the
- * form will update the model only when the control loses focus (blur event). If `escape` key is
- * pressed while the input field is focused, the value is reset to the value in the current model.
- *
- * 
- *   
- *     

- *       

- *         

- *         

- *       

- *       
user.name = 

- *     

- *   
- *   
- *     angular.module('optionsExample', [])
- *       .controller('ExampleController', ['$scope', function($scope) {
- *         $scope.user = { name: 'say', data: '' };
- *
- *         $scope.cancel = function(e) {
- *           if (e.keyCode === 27) {
- *             $scope.userForm.userName.$rollbackViewValue();
- *           }
- *         };
- *       }]);
- *   
- *   
- *     var model = element(by.binding('user.name'));
- *     var input = element(by.model('user.name'));
- *     var other = element(by.model('user.data'));
- *
- *     it('should allow custom events', function() {
- *       input.sendKeys(' hello');
- *       input.click();
- *       expect(model.getText()).toEqual('say');
- *       other.click();
- *       expect(model.getText()).toEqual('say hello');
- *     });
- *
- *     it('should $rollbackViewValue when model changes', function() {
- *       input.sendKeys(' hello');
- *       expect(input.getAttribute('value')).toEqual('say hello');
- *       input.sendKeys(protractor.Key.ESCAPE);
- *       expect(input.getAttribute('value')).toEqual('say');
- *       other.click();
- *       expect(model.getText()).toEqual('say');
- *     });
- *   
- * 
- *
- * ### Debouncing updates
- *
- * The next example shows how to debounce model changes. Model will be updated only 1 sec after last change.
- * If the `Clear` button is pressed, any debounced action is canceled and the value becomes empty.
- *
- * 
- *   
- *     

- *       

- *         Name:
- *         
- *         

- *       

- *       
user.name = 

- *     

- *   
- *   
- *     angular.module('optionsExample', [])
- *       .controller('ExampleController', ['$scope', function($scope) {
- *         $scope.user = { name: 'say' };
- *       }]);
- *   
- * 
- *
- * ### Default events, extra triggers, and catch-all debounce values
- *
- * This example shows the relationship between "default" update events and
- * additional `updateOn` triggers.
- *
- * `default` events are those that are bound to the control, and when fired, update the `$viewValue`
- * via {@link ngModel.NgModelController#$setViewValue $setViewValue}. Every event that is not listed
- * in `updateOn` is considered a "default" event, since different control types have different
- * default events.
- *
- * The control in this example updates by "default", "click", and "blur", with different `debounce`
- * values. You can see that "click" doesn't have an individual `debounce` value -
- * therefore it uses the `*` debounce value.
- *
- * There is also a button that calls {@link ngModel.NgModelController#$setViewValue $setViewValue}
- * directly with a "custom" event. Since "custom" is not defined in the `updateOn` list,
- * it is considered a "default" event and will update the
- * control if "default" is defined in `updateOn`, and will receive the "default" debounce value.
- * Note that this is just to illustrate how custom controls would possibly call `$setViewValue`.
- *
- * You can change the `updateOn` and `debounce` configuration to test different scenarios. This
- * is done with {@link ngModel.NgModelController#$overrideModelOptions $overrideModelOptions}.
- *

- *
- *
- * ## Model updates and validation
- *
- * The default behaviour in `ngModel` is that the model value is set to `undefined` when the
- * validation determines that the value is invalid. By setting the `allowInvalid` property to true,
- * the model will still be updated even if the value is invalid.
- *
- *
- * ## Connecting to the scope
- *
- * By setting the `getterSetter` property to true you are telling ngModel that the `ngModel` expression
- * on the scope refers to a "getter/setter" function rather than the value itself.
- *
- * The following example shows how to bind to getter/setters:
- *
- * 
- *   
- *     

- *       

- *         
- *       

- *       
user.name = 

- *     

- *   
- *   
- *     angular.module('getterSetterExample', [])
- *       .controller('ExampleController', ['$scope', function($scope) {
- *         var _name = 'Brian';
- *         $scope.user = {
- *           name: function(newName) {
- *             return angular.isDefined(newName) ? (_name = newName) : _name;
- *           }
- *         };
- *       }]);
- *   
- * 
- *
- *
- * ## Programmatically changing options
- *
- * The `ngModelOptions` expression is only evaluated once when the directive is linked; it is not
- * watched for changes. However, it is possible to override the options on a single
- * {@link ngModel.NgModelController} instance with
- * {@link ngModel.NgModelController#$overrideModelOptions `NgModelController#$overrideModelOptions()`}.
- * See also the example for
- * {@link ngModelOptions#default-events-extra-triggers-and-catch-all-debounce-values
- * Default events, extra triggers, and catch-all debounce values}.
- *
- *
- * ## Specifying timezones
- *
- * You can specify the timezone that date/time input directives expect by providing its name in the
- * `timezone` property.
- *
- *
- * ## Formatting the value of `time` and `datetime-local`
- *
- * With the options `timeSecondsFormat` and `timeStripZeroSeconds` it is possible to adjust the value
- * that is displayed in the control. Note that browsers may apply their own formatting
- * in the user interface.
- *

+  /**
+   * @ngdoc directive
+   * @name ngModelOptions
+   * @restrict A
+   * @priority 10
+   *
+   * @description
+   * This directive allows you to modify the behaviour of {@link ngModel} directives within your
+   * application. You can specify an `ngModelOptions` directive on any element. All {@link ngModel}
+   * directives will use the options of their nearest `ngModelOptions` ancestor.
+   *
+   * The `ngModelOptions` settings are found by evaluating the value of the attribute directive as
+   * an AngularJS expression. This expression should evaluate to an object, whose properties contain
+   * the settings. For example: `

+   *   

+   *     
+   *   

+   * 

+   * ```
+   *
+   * the `input` element will have the following settings
+   *
+   * ```js
+   * { allowInvalid: true, updateOn: 'default', debounce: 0 }
+   * ```
+   *
+   * Notice that the `debounce` setting was not inherited and used the default value instead.
+   *
+   * You can specify that all undefined settings are automatically inherited from an ancestor by
+   * including a property with key of `"*"` and value of `"$inherit"`.
+   *
+   * For example given the following fragment of HTML
+   *
+   *
+   * ```html
+   * 

+   *   

+   *     
+   *   

+   * 

+   * ```
+   *
+   * the `input` element will have the following settings
+   *
+   * ```js
+   * { allowInvalid: true, updateOn: 'default', debounce: 200 }
+   * ```
+   *
+   * Notice that the `debounce` setting now inherits the value from the outer `
` element.
+   *
+   * If you are creating a reusable component then you should be careful when using `"*": "$inherit"`
+   * since you may inadvertently inherit a setting in the future that changes the behavior of your component.
+   *
+   *
+   * ## Triggering and debouncing model updates
+   *
+   * The `updateOn` and `debounce` properties allow you to specify a custom list of events that will
+   * trigger a model update and/or a debouncing delay so that the actual update only takes place when
+   * a timer expires; this timer will be reset after another change takes place.
+   *
+   * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
+   * be different from the value in the actual model. This means that if you update the model you
+   * should also invoke {@link ngModel.NgModelController#$rollbackViewValue} on the relevant input field in
+   * order to make sure it is synchronized with the model and that any debounced action is canceled.
+   *
+   * The easiest way to reference the control's {@link ngModel.NgModelController#$rollbackViewValue}
+   * method is by making sure the input is placed inside a form that has a `name` attribute. This is
+   * important because `form` controllers are published to the related scope under the name in their
+   * `name` attribute.
+   *
+   * Any pending changes will take place immediately when an enclosing form is submitted via the
+   * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
+   * to have access to the updated model.
+   *
+   * ### Overriding immediate updates
+   *
+   * The following example shows how to override immediate updates. Changes on the inputs within the
+   * form will update the model only when the control loses focus (blur event). If `escape` key is
+   * pressed while the input field is focused, the value is reset to the value in the current model.
+   *
+   * 
+   *   
+   *     

+   *       

+   *         

+   *         

+   *       

+   *       
user.name = 

+   *     

+   *   
+   *   
+   *     angular.module('optionsExample', [])
+   *       .controller('ExampleController', ['$scope', function($scope) {
+   *         $scope.user = { name: 'say', data: '' };
+   *
+   *         $scope.cancel = function(e) {
+   *           if (e.keyCode === 27) {
+   *             $scope.userForm.userName.$rollbackViewValue();
+   *           }
+   *         };
+   *       }]);
+   *   
+   *   
+   *     var model = element(by.binding('user.name'));
+   *     var input = element(by.model('user.name'));
+   *     var other = element(by.model('user.data'));
+   *
+   *     it('should allow custom events', function() {
+   *       input.sendKeys(' hello');
+   *       input.click();
+   *       expect(model.getText()).toEqual('say');
+   *       other.click();
+   *       expect(model.getText()).toEqual('say hello');
+   *     });
+   *
+   *     it('should $rollbackViewValue when model changes', function() {
+   *       input.sendKeys(' hello');
+   *       expect(input.getAttribute('value')).toEqual('say hello');
+   *       input.sendKeys(protractor.Key.ESCAPE);
+   *       expect(input.getAttribute('value')).toEqual('say');
+   *       other.click();
+   *       expect(model.getText()).toEqual('say');
+   *     });
+   *   
+   * 
+   *
+   * ### Debouncing updates
+   *
+   * The next example shows how to debounce model changes. Model will be updated only 1 sec after last change.
+   * If the `Clear` button is pressed, any debounced action is canceled and the value becomes empty.
+   *
+   * 
+   *   
+   *     

+   *       

+   *         Name:
+   *         
+   *         

+   *       

+   *       
user.name = 

+   *     

+   *   
+   *   
+   *     angular.module('optionsExample', [])
+   *       .controller('ExampleController', ['$scope', function($scope) {
+   *         $scope.user = { name: 'say' };
+   *       }]);
+   *   
+   * 
+   *
+   * ### Default events, extra triggers, and catch-all debounce values
+   *
+   * This example shows the relationship between "default" update events and
+   * additional `updateOn` triggers.
+   *
+   * `default` events are those that are bound to the control, and when fired, update the `$viewValue`
+   * via {@link ngModel.NgModelController#$setViewValue $setViewValue}. Every event that is not listed
+   * in `updateOn` is considered a "default" event, since different control types have different
+   * default events.
+   *
+   * The control in this example updates by "default", "click", and "blur", with different `debounce`
+   * values. You can see that "click" doesn't have an individual `debounce` value -
+   * therefore it uses the `*` debounce value.
+   *
+   * There is also a button that calls {@link ngModel.NgModelController#$setViewValue $setViewValue}
+   * directly with a "custom" event. Since "custom" is not defined in the `updateOn` list,
+   * it is considered a "default" event and will update the
+   * control if "default" is defined in `updateOn`, and will receive the "default" debounce value.
+   * Note that this is just to illustrate how custom controls would possibly call `$setViewValue`.
+   *
+   * You can change the `updateOn` and `debounce` configuration to test different scenarios. This
+   * is done with {@link ngModel.NgModelController#$overrideModelOptions $overrideModelOptions}.
+   *
+

- *  
- *
- * @param {Object} ngModelOptions options to apply to {@link ngModel} directives on this element and
- *   and its descendents.
- *
- * **General options**:
- *
- *   - `updateOn`: string specifying which event should the input be bound to. You can set several
- *     events using an space delimited list. There is a special event called `default` that
- *     matches the default events belonging to the control. These are the events that are bound to
- *     the control, and when fired, update the `$viewValue` via `$setViewValue`.
- *
- *     `ngModelOptions` considers every event that is not listed in `updateOn` a "default" event,
- *     since different control types use different default events.
- *
- *     See also the section {@link ngModelOptions#triggering-and-debouncing-model-updates
- *     Triggering and debouncing model updates}.
- *
- *   - `debounce`: integer value which contains the debounce model update value in milliseconds. A
- *     value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
- *     custom value for each event. For example:
- *     ```
- *     ng-model-options="{
- *       updateOn: 'default blur',
- *       debounce: { 'default': 500, 'blur': 0 }
- *     }"
- *     ```
- *     You can use the `*` key to specify a debounce value that applies to all events that are not
- *     specifically listed. In the following example, `mouseup` would have a debounce delay of 1000:
- *     ```
- *     ng-model-options="{
- *       updateOn: 'default blur mouseup',
- *       debounce: { 'default': 500, 'blur': 0, '*': 1000 }
- *     }"
- *     ```
- *   - `allowInvalid`: boolean value which indicates that the model can be set with values that did
- *     not validate correctly instead of the default behavior of setting the model to undefined.
- *   - `getterSetter`: boolean value which determines whether or not to treat functions bound to
- *     `ngModel` as getters/setters.
- *
- *
- *  **Input-type specific options**:
- *
- *   - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
- *     ``, ``, ... . It understands UTC/GMT and the
- *     continental US time zone abbreviations, but for general use, use a time zone offset, for
- *     example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
- *     If not specified, the timezone of the browser will be used.
- *     Note that changing the timezone will have no effect on the current date, and is only applied after
- *     the next input / model change.
- *
- *   - `timeSecondsFormat`: Defines if the `time` and `datetime-local` types should show seconds and
- *     milliseconds. The option follows the format string of {@link date date filter}.
- *     By default, the options is `undefined` which is equal to `'ss.sss'` (seconds and milliseconds).
- *     The other options are `'ss'` (strips milliseconds), and `''` (empty string), which strips both
- *     seconds and milliseconds.
- *     Note that browsers that support `time` and `datetime-local` require the hour and minutes
- *     part of the time string, and may show the value differently in the user interface.
- *     {@link ngModelOptions#formatting-the-value-of-time-and-datetime-local- See the example}.
- *
- *   - `timeStripZeroSeconds`: Defines if the `time` and `datetime-local` types should strip the
- *     seconds and milliseconds from the formatted value if they are zero. This option is applied
- *     after `timeSecondsFormat`.
- *     This option can be used to make the formatting consistent over different browsers, as some
- *     browsers with support for `time` will natively hide the milliseconds and
- *     seconds if they are zero, but others won't, and browsers that don't implement these input
- *     types will always show the full string.
- *     {@link ngModelOptions#formatting-the-value-of-time-and-datetime-local- See the example}.

+   * The following example shows how to bind to getter/setters:
+   *
+   * 
+   *   
+   *     

+   *       

+   *         
+   *       

+   *       
user.name = 

+   *     

+   *   
+   *   
+   *     angular.module('getterSetterExample', [])
+   *       .controller('ExampleController', ['$scope', function($scope) {
+   *         var _name = 'Brian';
+   *         $scope.user = {
+   *           name: function(newName) {
+   *             return angular.isDefined(newName) ? (_name = newName) : _name;
+   *           }
+   *         };
+   *       }]);
+   *   
+   * 
+   *
+   *
+   * ## Programmatically changing options
+   *
+   * The `ngModelOptions` expression is only evaluated once when the directive is linked; it is not
+   * watched for changes. However, it is possible to override the options on a single
+   * {@link ngModel.NgModelController} instance with
+   * {@link ngModel.NgModelController#$overrideModelOptions `NgModelController#$overrideModelOptions()`}.
+   * See also the example for
+   * {@link ngModelOptions#default-events-extra-triggers-and-catch-all-debounce-values
+   * Default events, extra triggers, and catch-all debounce values}.
+   *
+   *
+   * ## Specifying timezones
+   *
+   * You can specify the timezone that date/time input directives expect by providing its name in the
+   * `timezone` property.
+   *
+   *
+   * ## Formatting the value of `time` and `datetime-local`
+   *
+   * With the options `timeSecondsFormat` and `timeStripZeroSeconds` it is possible to adjust the value
+   * that is displayed in the control. Note that browsers may apply their own formatting
+   * in the user interface.
+   *
+     
+       
+         
+       
+       
+          angular.module('timeExample', [])
+            .component('timeExample', {
+              templateUrl: 'timeExample.html',
+              controller: function() {
+                this.time = new Date(1970, 0, 1, 14, 57, 0);
+  
+                this.options = {
+                  timeSecondsFormat: 'ss',
+                  timeStripZeroSeconds: true
+                };
+  
+                this.optionChange = function() {
+                  this.timeForm.timeFormatted.$overrideModelOptions(this.options);
+                  this.time = new Date(this.time);
+                };
+              }
+            });
+       
+

+           With options:
+           
+           

+  
+           Options:

+           timeSecondsFormat:
+           
+           

+           timeStripZeroSeconds:
+           
+          

+        
+   *  
+   *
+   * @param {Object} ngModelOptions options to apply to {@link ngModel} directives on this element and
+   *   and its descendents.
+   *
+   * **General options**:
+   *
+   *   - `updateOn`: string specifying which event should the input be bound to. You can set several
+   *     events using an space delimited list. There is a special event called `default` that
+   *     matches the default events belonging to the control. These are the events that are bound to
+   *     the control, and when fired, update the `$viewValue` via `$setViewValue`.
+   *
+   *     `ngModelOptions` considers every event that is not listed in `updateOn` a "default" event,
+   *     since different control types use different default events.
+   *
+   *     See also the section {@link ngModelOptions#triggering-and-debouncing-model-updates
+   *     Triggering and debouncing model updates}.
+   *
+   *   - `debounce`: integer value which contains the debounce model update value in milliseconds. A
+   *     value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
+   *     custom value for each event. For example:
+   *     ```
+   *     ng-model-options="{
+   *       updateOn: 'default blur',
+   *       debounce: { 'default': 500, 'blur': 0 }
+   *     }"
+   *     ```
+   *     You can use the `*` key to specify a debounce value that applies to all events that are not
+   *     specifically listed. In the following example, `mouseup` would have a debounce delay of 1000:
+   *     ```
+   *     ng-model-options="{
+   *       updateOn: 'default blur mouseup',
+   *       debounce: { 'default': 500, 'blur': 0, '*': 1000 }
+   *     }"
+   *     ```
+   *   - `allowInvalid`: boolean value which indicates that the model can be set with values that did
+   *     not validate correctly instead of the default behavior of setting the model to undefined.
+   *   - `getterSetter`: boolean value which determines whether or not to treat functions bound to
+   *     `ngModel` as getters/setters.
+   *
+   *
+   *  **Input-type specific options**:
+   *
+   *   - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
+   *     ``, ``, ... . It understands UTC/GMT and the
+   *     continental US time zone abbreviations, but for general use, use a time zone offset, for
+   *     example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
+   *     If not specified, the timezone of the browser will be used.
+   *     Note that changing the timezone will have no effect on the current date, and is only applied after
+   *     the next input / model change.
+   *
+   *   - `timeSecondsFormat`: Defines if the `time` and `datetime-local` types should show seconds and
+   *     milliseconds. The option follows the format string of {@link date date filter}.
+   *     By default, the options is `undefined` which is equal to `'ss.sss'` (seconds and milliseconds).
+   *     The other options are `'ss'` (strips milliseconds), and `''` (empty string), which strips both
+   *     seconds and milliseconds.
+   *     Note that browsers that support `time` and `datetime-local` require the hour and minutes
+   *     part of the time string, and may show the value differently in the user interface.
+   *     {@link ngModelOptions#formatting-the-value-of-time-and-datetime-local- See the example}.
+   *
+   *   - `timeStripZeroSeconds`: Defines if the `time` and `datetime-local` types should strip the
+   *     seconds and milliseconds from the formatted value if they are zero. This option is applied
+   *     after `timeSecondsFormat`.
+   *     This option can be used to make the formatting consistent over different browsers, as some
+   *     browsers with support for `time` will natively hide the milliseconds and
+   *     seconds if they are zero, but others won't, and browsers that don't implement these input
+   *     types will always show the full string.
+   *     {@link ngModelOptions#formatting-the-value-of-time-and-datetime-local- See the example}.

+   * @ngdoc directive
+   * @name ngPluralize
+   * @restrict EA
+   *
+   * @description
+   * `ngPluralize` is a directive that displays messages according to en-US localization rules.
+   * These rules are bundled with angular.js, but can be overridden
+   * (see {@link guide/i18n AngularJS i18n} dev guide). You configure ngPluralize directive
+   * by specifying the mappings between
+   * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
+   * and the strings to be displayed.
+   *
+   * ## Plural categories and explicit number rules
+   * There are two
+   * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
+   * in AngularJS's default en-US locale: "one" and "other".
+   *
+   * While a plural category may match many numbers (for example, in en-US locale, "other" can match
+   * any number that is not 1), an explicit number rule can only match one number. For example, the
+   * explicit number rule for "3" matches the number 3. There are examples of plural categories
+   * and explicit number rules throughout the rest of this documentation.
+   *
+   * ## Configuring ngPluralize
+   * You configure ngPluralize by providing 2 attributes: `count` and `when`.
+   * You can also provide an optional attribute, `offset`.
+   *
+   * The value of the `count` attribute can be either a string or an {@link guide/expression
+   * AngularJS expression}; these are evaluated on the current scope for its bound value.
+   *
+   * The `when` attribute specifies the mappings between plural categories and the actual
+   * string to be displayed. The value of the attribute should be a JSON object.
+   *
+   * The following example shows how to configure ngPluralize:
+   *
+   * ```html
+   * 
+   * 
+   *```
+   *
+   * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
+   * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
+   * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
+   * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
+   * show "a dozen people are viewing".
+   *
+   * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted
+   * into pluralized strings. In the previous example, AngularJS will replace `{}` with
+   * `{{personCount}}`. The closed braces `{}` is a placeholder
+   * for {{numberExpression}}.
+   *
+   * If no rule is defined for a category, then an empty string is displayed and a warning is generated.
+   * Note that some locales define more categories than `one` and `other`. For example, fr-fr defines `few` and `many`.
+   *
+   * ## Configuring ngPluralize with offset
+   * The `offset` attribute allows further customization of pluralized text, which can result in
+   * a better user experience. For example, instead of the message "4 people are viewing this document",
+   * you might display "John, Kate and 2 others are viewing this document".
+   * The offset attribute allows you to offset a number by any desired value.
+   * Let's take a look at an example:
+   *
+   * ```html
+   * 
+   * 
+   * ```
+   *
+   * Notice that we are still using two plural categories(one, other), but we added
+   * three explicit number rules 0, 1 and 2.
+   * When one person, perhaps John, views the document, "John is viewing" will be shown.
+   * When three people view the document, no explicit number rule is found, so
+   * an offset of 2 is taken off 3, and AngularJS uses 1 to decide the plural category.
+   * In this case, plural category 'one' is matched and "John, Mary and one other person are viewing"
+   * is shown.
+   *
+   * Note that when you specify offsets, you must provide explicit number rules for
+   * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
+   * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
+   * plural categories "one" and "other".
+   *
+   * @param {string|expression} count The variable to be bound to.
+   * @param {string} when The mapping between plural category to its corresponding strings.
+   * @param {number=} offset Offset to deduct from the total number.
+   *
+   * @example
+      
+        
+          
+

- * @ngdoc directive
- * @name ngRef
- * @restrict A
- *
- * @description
- * The `ngRef` attribute tells AngularJS to assign the controller of a component (or a directive)
- * to the given property in the current scope. It is also possible to add the jqlite-wrapped DOM
- * element to the scope.
- *
- * If the element with `ngRef` is destroyed `null` is assigned to the property.
- *
- * Note that if you want to assign from a child into the parent scope, you must initialize the
- * target property on the parent scope, otherwise `ngRef` will assign on the child scope.
- * This commonly happens when assigning elements or components wrapped in {@link ngIf} or
- * {@link ngRepeat}. See the second example below.
- *
- *
- * @element ANY
- * @param {string} ngRef property name - A valid AngularJS expression identifier to which the
- *                       controller or jqlite-wrapped DOM element will be bound.
- * @param {string=} ngRefRead read value - The name of a directive (or component) on this element,
- *                            or the special string `$element`. If a name is provided, `ngRef` will
- *                            assign the matching controller. If `$element` is provided, the element
- *                            itself is assigned (even if a controller is available).
- *
- *
- * @example
- * ### Simple toggle
- * This example shows how the controller of the component toggle
- * is reused in the template through the scope to use its logic.
- * 
- *   
- *     
- *     
- *     

- *       You are using a component in the same template to show it.
- *     

- *   
- *   
- *     angular.module('myApp', [])
- *     .component('myToggle', {
- *       controller: function ToggleController() {
- *         var opened = false;
- *         this.isOpen = function() { return opened; };
- *         this.toggle = function() { opened = !opened; };
- *       }
- *     });
- *   
- *   
- *      it('should publish the toggle into the scope', function() {
- *        var toggle = element(by.buttonText('Toggle'));
- *        expect(toggle.evaluate('myToggle.isOpen()')).toEqual(false);
- *        toggle.click();
- *        expect(toggle.evaluate('myToggle.isOpen()')).toEqual(true);
- *      });
- *   
- * 
- *
- * @example
- * ### ngRef inside scopes
- * This example shows how `ngRef` works with child scopes. The `ngRepeat`-ed `myWrapper` components
- * are assigned to the scope of `myRoot`, because the `toggles` property has been initialized.
- * The repeated `myToggle` components are published to the child scopes created by `ngRepeat`.
- * `ngIf` behaves similarly - the assignment of `myToggle` happens in the `ngIf` child scope,
- * because the target property has not been initialized on the `myRoot` component controller.
- *
- * 
- *   
- *     
- *   
- *   
- *     angular.module('myApp', [])
- *     .component('myRoot', {
- *       templateUrl: 'root.html',
- *       controller: function() {
- *         this.wrappers = []; // initialize the array so that the wrappers are assigned into the parent scope
- *       }
- *     })
- *     .component('myToggle', {
- *       template: 'myToggle',
- *       transclude: true,
- *       controller: function ToggleController() {
- *         var opened = false;
- *         this.isOpen = function() { return opened; };
- *         this.toggle = function() { opened = !opened; };
- *       }
- *     })
- *     .component('myWrapper', {
- *       transclude: true,
- *       template: 'myWrapper' +

-/**
- * @ngdoc directive
- * @name ngRepeat
- * @multiElement
- * @restrict A
- *
- * @description
- * The `ngRepeat` directive instantiates a template once per item from a collection. Each template
- * instance gets its own scope, where the given loop variable is set to the current collection item,
- * and `$index` is set to the item index or key.
- *
- * Special properties are exposed on the local scope of each template instance, including:
- *
- * | Variable  | Type            | Details                                                                     |
- * |-----------|-----------------|-----------------------------------------------------------------------------|
- * | `$index`  | {@type number}  | iterator offset of the repeated element (0..length-1)                       |
- * | `$first`  | {@type boolean} | true if the repeated element is first in the iterator.                      |
- * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |
- * | `$last`   | {@type boolean} | true if the repeated element is last in the iterator.                       |
- * | `$even`   | {@type boolean} | true if the iterator position `$index` is even (otherwise false).           |
- * | `$odd`    | {@type boolean} | true if the iterator position `$index` is odd (otherwise false).            |
- *
- * 

- *   Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}.
- *   This may be useful when, for instance, nesting ngRepeats.
- * 

- *
- *
- * ## Iterating over object properties
- *
- * It is possible to get `ngRepeat` to iterate over the properties of an object using the following
- * syntax:
- *
- * ```js
- * 
 ... 

- * ```
- *
- * However, there are a few limitations compared to array iteration:
- *
- * - The JavaScript specification does not define the order of keys
- *   returned for an object, so AngularJS relies on the order returned by the browser
- *   when running `for key in myObj`. Browsers generally follow the strategy of providing
- *   keys in the order in which they were defined, although there are exceptions when keys are deleted
- *   and reinstated. See the
- *   [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes).
- *
- * - `ngRepeat` will silently *ignore* object keys starting with `$`, because
- *   it's a prefix used by AngularJS for public (`$`) and private (`$$`) properties.
- *
- * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with
- *   objects, and will throw an error if used with one.
- *
- * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array
- * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could
- * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter)
- * or implement a `$watch` on the object yourself.
- *
- *
- * ## Tracking and Duplicates
- *
- * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in
- * the collection. When a change happens, `ngRepeat` then makes the corresponding changes to the DOM:
- *
- * * When an item is added, a new instance of the template is added to the DOM.
- * * When an item is removed, its template instance is removed from the DOM.
- * * When items are reordered, their respective templates are reordered in the DOM.
- *
- * To minimize creation of DOM elements, `ngRepeat` uses a function
- * to "keep track" of all items in the collection and their corresponding DOM elements.
- * For example, if an item is added to the collection, `ngRepeat` will know that all other items
- * already have DOM elements, and will not re-render them.
- *
- * All different types of tracking functions, their syntax, and and their support for duplicate
- * items in collections can be found in the
- * {@link ngRepeat#ngRepeat-arguments ngRepeat expression description}.
- *
- * 

- * **Best Practice:** If you are working with objects that have a unique identifier property, you
- * should track by this identifier instead of the object instance,
- * e.g. `item in items track by item.id`.
- * Should you reload your data later, `ngRepeat` will not have to rebuild the DOM elements for items
- * it has already rendered, even if the JavaScript objects in the collection have been substituted
- * for new ones. For large collections, this significantly improves rendering performance.
- * 

- *
- * ### Effects of DOM Element re-use
- *
- * When DOM elements are re-used, ngRepeat updates the scope for the element, which will
- * automatically update any active bindings on the template. However, other
- * functionality will not be updated, because the element is not re-created:
- *
- * - Directives are not re-compiled
- * - {@link guide/expression#one-time-binding one-time expressions} on the repeated template are not
- * updated if they have stabilized.
- *
- * The above affects all kinds of element re-use due to tracking, but may be especially visible
- * when tracking by `$index` due to the way ngRepeat re-uses elements.
- *
- * The following example shows the effects of different actions with tracking:
-
-  
-    
-      angular.module('ngRepeat', ['ngAnimate']).controller('repeatController', function($scope) {
-        var friends = [
-          {name:'John', age:25},
-          {name:'Mary', age:40},
-          {name:'Peter', age:85}
-        ];
-
-        $scope.removeFirst = function() {
-          $scope.friends.shift();
-        };
-
-        $scope.updateAge = function() {
-          $scope.friends.forEach(function(el) {
-            el.age = el.age + 5;
-          });
-        };

-    
-    
-      

-        
    
-          
  1. When you click "Update Age", only the first list updates the age, because all others have
-          a one-time binding on the age property. If you then click "Copy", the current friend list
-          is copied, and now the second list updates the age, because the identity of the collection items
-          has changed and the list must be re-rendered. The 3rd and 4th list stay the same, because all the
-          items are already known according to their tracking functions.
-          
    2. 
-          
  2. When you click "Remove First", the 4th list has the wrong age on both remaining items. This is
-          due to tracking by $index: when the first collection item is removed, ngRepeat reuses the first
-          DOM element for the new first collection item, and so on. Since the age property is one-time
-          bound, the value remains from the collection item which was previously at this index.
-

- * ## Special repeat start and end points
- * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
- * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.
- * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)
- * up to and including the ending HTML tag where **ng-repeat-end** is placed.
- *
- * The example below makes use of this feature:
- * ```html
- *   

- *     Header {{ item }}
- *   

- *   

- *     Body {{ item }}
- *   

- *   

- *     Footer {{ item }}
- *   

- * ```
- *
- * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
- * ```html
- *   

- *     Header A
- *   

- *   

- *     Body A
- *   

- *   

- *     Footer A
- *   

- *   

- *     Header B
- *   

- *   

- *     Body B
- *   

- *   

- *     Footer B
- *   

- * ```
- *
- * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
- * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).
- *
- * @animations
- * | Animation                        | Occurs                              |
- * |----------------------------------|-------------------------------------|
- * | {@link ng.$animate#enter enter} | when a new item is added to the list or when an item is revealed after a filter |
- * | {@link ng.$animate#leave leave} | when an item is removed from the list or when an item is filtered out |
- * | {@link ng.$animate#move move } | when an adjacent item is filtered out causing a reorder or when the item contents are reordered |
- *
- * See the example below for defining CSS animations with ngRepeat.
- *
- * @element ANY
- * @scope
- * @priority 1000
- * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These
- *   formats are currently supported:
- *
- *   * `variable in expression` – where variable is the user defined loop variable and `expression`
- *     is a scope expression giving the collection to enumerate.
- *
- *     For example: `album in artist.albums`.
- *
- *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
- *     and `expression` is the scope expression giving the collection to enumerate.
- *
- *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
- *
- *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression
- *     which can be used to associate the objects in the collection with the DOM elements. If no tracking expression
- *     is specified, ng-repeat associates elements by identity. It is an error to have
- *     more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are
- *     mapped to the same DOM element, which is not possible.)
- *
- *     *Default tracking: $id()*: `item in items` is equivalent to `item in items track by $id(item)`.
- *     This implies that the DOM elements will be associated by item identity in the collection.
- *
- *     The built-in `$id()` function can be used to assign a unique
- *     `$$hashKey` property to each item in the collection. This property is then used as a key to associated DOM elements
- *     with the corresponding item in the collection by identity. Moving the same object would move
- *     the DOM element in the same way in the DOM.
- *     Note that the default id function does not support duplicate primitive values (`number`, `string`),
- *     but supports duplictae non-primitive values (`object`) that are *equal* in shape.
- *
- *     *Custom Expression*: It is possible to use any AngularJS expression to compute the tracking
- *     id, for example with a function, or using a property on the collection items.
- *     `item in items track by item.id` is a typical pattern when the items have a unique identifier,
- *     e.g. database id. In this case the object identity does not matter. Two objects are considered
- *     equivalent as long as their `id` property is same.
- *     Tracking by unique identifier is the most performant way and should be used whenever possible.
- *
- *     *$index*: This special property tracks the collection items by their index, and
- *     re-uses the DOM elements that match that index, e.g. `item in items track by $index`. This can
- *     be used for a performance improvement if no unique identfier is available and the identity of
- *     the collection items cannot be easily computed. It also allows duplicates.
- *
- *     

- *       Note: Re-using DOM elements can have unforeseen effects. Read the
- *       {@link ngRepeat#tracking-and-duplicates section on tracking and duplicates} for
- *       more info.
- *     

- *
- *     

- *       Note: the `track by` expression must come last - after any filters, and the alias expression:
- *       `item in items | filter:searchText as results  track by item.id`
- *     

- *
- *   * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the
- *     intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message
- *     when a filter is active on the repeater, but the filtered result set is empty.
- *
- *     For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after
- *     the items have been processed through the filter.
- *
- *     Please note that `as [variable name] is not an operator but rather a part of ngRepeat
- *     micro-syntax so it can be used only after all filters (and not as operator, inside an expression).
- *
- *     For example: `item in items | filter : x | orderBy : order | limitTo : limit as results track by item.id` .
- *
- * @example
- * This example uses `ngRepeat` to display a list of people. A filter is used to restrict the displayed
- * results by name or by age. New (entering) and removed (leaving) items are animated.

+  /**
+   * @ngdoc directive
+   * @name ngRef
+   * @restrict A
+   *
+   * @description
+   * The `ngRef` attribute tells AngularJS to assign the controller of a component (or a directive)
+   * to the given property in the current scope. It is also possible to add the jqlite-wrapped DOM
+   * element to the scope.
+   *
+   * If the element with `ngRef` is destroyed `null` is assigned to the property.
+   *
+   * Note that if you want to assign from a child into the parent scope, you must initialize the
+   * target property on the parent scope, otherwise `ngRef` will assign on the child scope.
+   * This commonly happens when assigning elements or components wrapped in {@link ngIf} or
+   * {@link ngRepeat}. See the second example below.
+   *
+   *
+   * @element ANY
+   * @param {string} ngRef property name - A valid AngularJS expression identifier to which the
+   *                       controller or jqlite-wrapped DOM element will be bound.
+   * @param {string=} ngRefRead read value - The name of a directive (or component) on this element,
+   *                            or the special string `$element`. If a name is provided, `ngRef` will
+   *                            assign the matching controller. If `$element` is provided, the element
+   *                            itself is assigned (even if a controller is available).
+   *
+   *
+   * @example
+   * ### Simple toggle
+   * This example shows how the controller of the component toggle
+   * is reused in the template through the scope to use its logic.
+   * 
+   *   
+   *     
+   *     
+   *     

+   *       You are using a component in the same template to show it.
+   *     

+   *   
+   *   
+   *     angular.module('myApp', [])
+   *     .component('myToggle', {
+   *       controller: function ToggleController() {
+   *         var opened = false;
+   *         this.isOpen = function() { return opened; };
+   *         this.toggle = function() { opened = !opened; };
+   *       }
+   *     });
+   *   
+   *   
+   *      it('should publish the toggle into the scope', function() {
+   *        var toggle = element(by.buttonText('Toggle'));
+   *        expect(toggle.evaluate('myToggle.isOpen()')).toEqual(false);
+   *        toggle.click();
+   *        expect(toggle.evaluate('myToggle.isOpen()')).toEqual(true);
+   *      });
+   *   
+   * 
+   *
+   * @example
+   * ### ngRef inside scopes
+   * This example shows how `ngRef` works with child scopes. The `ngRepeat`-ed `myWrapper` components
+   * are assigned to the scope of `myRoot`, because the `toggles` property has been initialized.
+   * The repeated `myToggle` components are published to the child scopes created by `ngRepeat`.
+   * `ngIf` behaves similarly - the assignment of `myToggle` happens in the `ngIf` child scope,
+   * because the target property has not been initialized on the `myRoot` component controller.
+   *
+   * 
+   *   
+   *     
+   *   
+   *   
+   *     angular.module('myApp', [])
+   *     .component('myRoot', {
+   *       templateUrl: 'root.html',
+   *       controller: function() {
+   *         this.wrappers = []; // initialize the array so that the wrappers are assigned into the parent scope
+   *       }
+   *     })
+   *     .component('myToggle', {
+   *       template: 'myToggle',
+   *       transclude: true,
+   *       controller: function ToggleController() {
+   *         var opened = false;
+   *         this.isOpen = function() { return opened; };
+   *         this.toggle = function() { opened = !opened; };
+   *       }
+   *     })
+   *     .component('myWrapper', {
+   *       transclude: true,
+   *       template: 'myWrapper' +
+   *         '

+   * @ngdoc directive
+   * @name ngRepeat
+   * @multiElement
+   * @restrict A
+   *
+   * @description
+   * The `ngRepeat` directive instantiates a template once per item from a collection. Each template
+   * instance gets its own scope, where the given loop variable is set to the current collection item,
+   * and `$index` is set to the item index or key.
+   *
+   * Special properties are exposed on the local scope of each template instance, including:
+   *
+   * | Variable  | Type            | Details                                                                     |
+   * |-----------|-----------------|-----------------------------------------------------------------------------|
+   * | `$index`  | {@type number}  | iterator offset of the repeated element (0..length-1)                       |
+   * | `$first`  | {@type boolean} | true if the repeated element is first in the iterator.                      |
+   * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |
+   * | `$last`   | {@type boolean} | true if the repeated element is last in the iterator.                       |
+   * | `$even`   | {@type boolean} | true if the iterator position `$index` is even (otherwise false).           |
+   * | `$odd`    | {@type boolean} | true if the iterator position `$index` is odd (otherwise false).            |
+   *
+   * 

+   *   Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}.
+   *   This may be useful when, for instance, nesting ngRepeats.
+   * 

+   *
+   *
+   * ## Iterating over object properties
+   *
+   * It is possible to get `ngRepeat` to iterate over the properties of an object using the following
+   * syntax:
+   *
+   * ```js
+   * 
 ... 

+   * ```
+   *
+   * However, there are a few limitations compared to array iteration:
+   *
+   * - The JavaScript specification does not define the order of keys
+   *   returned for an object, so AngularJS relies on the order returned by the browser
+   *   when running `for key in myObj`. Browsers generally follow the strategy of providing
+   *   keys in the order in which they were defined, although there are exceptions when keys are deleted
+   *   and reinstated. See the
+   *   [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes).
+   *
+   * - `ngRepeat` will silently *ignore* object keys starting with `$`, because
+   *   it's a prefix used by AngularJS for public (`$`) and private (`$$`) properties.
+   *
+   * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with
+   *   objects, and will throw an error if used with one.
+   *
+   * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array
+   * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could
+   * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter)
+   * or implement a `$watch` on the object yourself.
+   *
+   *
+   * ## Tracking and Duplicates
+   *
+   * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in
+   * the collection. When a change happens, `ngRepeat` then makes the corresponding changes to the DOM:
+   *
+   * * When an item is added, a new instance of the template is added to the DOM.
+   * * When an item is removed, its template instance is removed from the DOM.
+   * * When items are reordered, their respective templates are reordered in the DOM.
+   *
+   * To minimize creation of DOM elements, `ngRepeat` uses a function
+   * to "keep track" of all items in the collection and their corresponding DOM elements.
+   * For example, if an item is added to the collection, `ngRepeat` will know that all other items
+   * already have DOM elements, and will not re-render them.
+   *
+   * All different types of tracking functions, their syntax, and and their support for duplicate
+   * items in collections can be found in the
+   * {@link ngRepeat#ngRepeat-arguments ngRepeat expression description}.
+   *
+   * 

+   * **Best Practice:** If you are working with objects that have a unique identifier property, you
+   * should track by this identifier instead of the object instance,
+   * e.g. `item in items track by item.id`.
+   * Should you reload your data later, `ngRepeat` will not have to rebuild the DOM elements for items
+   * it has already rendered, even if the JavaScript objects in the collection have been substituted
+   * for new ones. For large collections, this significantly improves rendering performance.
+   * 

+   *
+   * ### Effects of DOM Element re-use
+   *
+   * When DOM elements are re-used, ngRepeat updates the scope for the element, which will
+   * automatically update any active bindings on the template. However, other
+   * functionality will not be updated, because the element is not re-created:
+   *
+   * - Directives are not re-compiled
+   * - {@link guide/expression#one-time-binding one-time expressions} on the repeated template are not
+   * updated if they have stabilized.
+   *
+   * The above affects all kinds of element re-use due to tracking, but may be especially visible
+   * when tracking by `$index` due to the way ngRepeat re-uses elements.
+   *
+   * The following example shows the effects of different actions with tracking:
+  
+    
+      
+        angular.module('ngRepeat', ['ngAnimate']).controller('repeatController', function($scope) {
+          var friends = [
+            {name:'John', age:25},
+            {name:'Mary', age:40},
+            {name:'Peter', age:85}
+          ];
+  
+          $scope.removeFirst = function() {
+            $scope.friends.shift();
+          };
+  
+          $scope.updateAge = function() {
+            $scope.friends.forEach(function(el) {
+              el.age = el.age + 5;
+            });
+          };
+  
+          $scope.copy = function() {
+            $scope.friends = angular.copy($scope.friends);
+          };
+  
+          $scope.reset = function() {
+            $scope.friends = angular.copy(friends);
+          };
+  
+          $scope.reset();
         });
-      };
-    }
-  };

-/**
- * @ngdoc directive
- * @name ngShow
- * @multiElement
- *
- * @description
- * The `ngShow` directive shows or hides the given HTML element based on the expression provided to
- * the `ngShow` attribute.
- *
- * The element is shown or hidden by removing or adding the `.ng-hide` CSS class onto the element.
- * The `.ng-hide` CSS class is predefined in AngularJS and sets the display style to none (using an
- * `!important` flag). For CSP mode please add `angular-csp.css` to your HTML file (see
- * {@link ng.directive:ngCsp ngCsp}).
- *
- * ```html
- * 
- * 

- *
- * 
- * 

- * ```
- *
- * When the `ngShow` expression evaluates to a falsy value then the `.ng-hide` CSS class is added
- * to the class attribute on the element causing it to become hidden. When truthy, the `.ng-hide`
- * CSS class is removed from the element causing the element not to appear hidden.
- *
- * ## Why is `!important` used?
- *
- * You may be wondering why `!important` is used for the `.ng-hide` CSS class. This is because the
- * `.ng-hide` selector can be easily overridden by heavier selectors. For example, something as
- * simple as changing the display style on a HTML list item would make hidden elements appear
- * visible. This also becomes a bigger issue when dealing with CSS frameworks.
- *
- * By using `!important`, the show and hide behavior will work as expected despite any clash between
- * CSS selector specificity (when `!important` isn't used with any conflicting styles). If a
- * developer chooses to override the styling to change how to hide an element then it is just a
- * matter of using `!important` in their own CSS code.
- *
- * ### Overriding `.ng-hide`
- *
- * By default, the `.ng-hide` class will style the element with `display: none !important`. If you
- * wish to change the hide behavior with `ngShow`/`ngHide`, you can simply overwrite the styles for
- * the `.ng-hide` CSS class. Note that the selector that needs to be used is actually
- * `.ng-hide:not(.ng-hide-animate)` to cope with extra animation classes that can be added.
- *
- * ```css
- * .ng-hide:not(.ng-hide-animate) {
- *   /* These are just alternative ways of hiding an element */
- *   display: block!important;
- *   position: absolute;
- *   top: -9999px;
- *   left: -9999px;
- * }
- * ```
- *
- * By default you don't need to override anything in CSS and the animations will work around the
- * display style.
- *
- * @animations
- * | Animation                                           | Occurs                                                                                                        |
- * |-----------------------------------------------------|---------------------------------------------------------------------------------------------------------------|
- * | {@link $animate#addClass addClass} `.ng-hide`       | After the `ngShow` expression evaluates to a non truthy value and just before the contents are set to hidden. |
- * | {@link $animate#removeClass removeClass} `.ng-hide` | After the `ngShow` expression evaluates to a truthy value and just before contents are set to visible.        |
- *
- * Animations in `ngShow`/`ngHide` work with the show and hide events that are triggered when the
- * directive expression is true and false. This system works like the animation system present with
- * `ngClass` except that you must also include the `!important` flag to override the display
- * property so that the elements are not actually hidden during the animation.
- *
- * ```css
- * /* A working example can be found at the bottom of this page. */
- * .my-element.ng-hide-add, .my-element.ng-hide-remove {
- *   transition: all 0.5s linear;
- * }
- *
- * .my-element.ng-hide-add { ... }
- * .my-element.ng-hide-add.ng-hide-add-active { ... }
- * .my-element.ng-hide-remove { ... }
- * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
- * ```
- *
- * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display property
- * to block during animation states - ngAnimate will automatically handle the style toggling for you.
- *
- * @element ANY
- * @param {expression} ngShow If the {@link guide/expression expression} is truthy/falsy then the
- *                            element is shown/hidden respectively.
- *
- * @example
- * A simple example, animating the element's opacity:
- *
-  
-    
-      Show: 

-      

-        I show up when your checkbox is checked.
-      

-    
-    
-      .animate-show-hide.ng-hide {
-        opacity: 0;
-      }
+      
+      
+        

+          
    
+            
  1. When you click "Update Age", only the first list updates the age, because all others have
+            a one-time binding on the age property. If you then click "Copy", the current friend list
+            is copied, and now the second list updates the age, because the identity of the collection items
+            has changed and the list must be re-rendered. The 3rd and 4th list stay the same, because all the
+            items are already known according to their tracking functions.
+            
    2. 
+            
  2. When you click "Remove First", the 4th list has the wrong age on both remaining items. This is
+            due to tracking by $index: when the first collection item is removed, ngRepeat reuses the first
+            DOM element for the new first collection item, and so on. Since the age property is one-time
+            bound, the value remains from the collection item which was previously at this index.
+

+   * ## Special repeat start and end points
+   * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
+   * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.
+   * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)
+   * up to and including the ending HTML tag where **ng-repeat-end** is placed.
+   *
+   * The example below makes use of this feature:
+   * ```html
+   *   

+   *     Header {{ item }}
+   *   

+   *   

+   *     Body {{ item }}
+   *   

+   *   

+   *     Footer {{ item }}
+   *   

+   * ```
+   *
+   * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
+   * ```html
+   *   

+   *     Header A
+   *   

+   *   

+   *     Body A
+   *   

+   *   

+   *     Footer A
+   *   

+   *   

+   *     Header B
+   *   

+   *   

+   *     Body B
+   *   

+   *   

+   *     Footer B
+   *   

+   * ```
+   *
+   * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
+   * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).

+   *
+   * @element ANY
+   * @scope
+   * @priority 1000
+   * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These
+   *   formats are currently supported:
+   *
+   *   * `variable in expression` – where variable is the user defined loop variable and `expression`
+   *     is a scope expression giving the collection to enumerate.
+   *
+   *     For example: `album in artist.albums`.
+   *
+   *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
+   *     and `expression` is the scope expression giving the collection to enumerate.
+   *
+   *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
+   *
+   *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression
+   *     which can be used to associate the objects in the collection with the DOM elements. If no tracking expression
+   *     is specified, ng-repeat associates elements by identity. It is an error to have
+   *     more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are
+   *     mapped to the same DOM element, which is not possible.)
+   *
+   *     *Default tracking: $id()*: `item in items` is equivalent to `item in items track by $id(item)`.
+   *     This implies that the DOM elements will be associated by item identity in the collection.
+   *
+   *     The built-in `$id()` function can be used to assign a unique
+   *     `$$hashKey` property to each item in the collection. This property is then used as a key to associated DOM elements
+   *     with the corresponding item in the collection by identity. Moving the same object would move
+   *     the DOM element in the same way in the DOM.
+   *     Note that the default id function does not support duplicate primitive values (`number`, `string`),
+   *     but supports duplictae non-primitive values (`object`) that are *equal* in shape.
+   *
+   *     *Custom Expression*: It is possible to use any AngularJS expression to compute the tracking
+   *     id, for example with a function, or using a property on the collection items.
+   *     `item in items track by item.id` is a typical pattern when the items have a unique identifier,
+   *     e.g. database id. In this case the object identity does not matter. Two objects are considered
+   *     equivalent as long as their `id` property is same.
+   *     Tracking by unique identifier is the most performant way and should be used whenever possible.
+   *
+   *     *$index*: This special property tracks the collection items by their index, and
+   *     re-uses the DOM elements that match that index, e.g. `item in items track by $index`. This can
+   *     be used for a performance improvement if no unique identfier is available and the identity of
+   *     the collection items cannot be easily computed. It also allows duplicates.
+   *
+   *     

+   *       Note: Re-using DOM elements can have unforeseen effects. Read the
+   *       {@link ngRepeat#tracking-and-duplicates section on tracking and duplicates} for
+   *       more info.
+   *     

+   *
+   *     

+   *       Note: the `track by` expression must come last - after any filters, and the alias expression:
+   *       `item in items | filter:searchText as results  track by item.id`
+   *     

+   *
+   *   * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the
+   *     intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message
+   *     when a filter is active on the repeater, but the filtered result set is empty.
+   *
+   *     For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after
+   *     the items have been processed through the filter.
+   *
+   *     Please note that `as [variable name] is not an operator but rather a part of ngRepeat
+   *     micro-syntax so it can be used only after all filters (and not as operator, inside an expression).
+   *
+   *     For example: `item in items | filter : x | orderBy : order | limitTo : limit as results track by item.id` .
+   *
+   * @example
+   * This example uses `ngRepeat` to display a list of people. A filter is used to restrict the displayed
+   * results by name or by age. New (entering) and removed (leaving) items are animated.

-/**
- * @ngdoc directive
- * @name ngHide
- * @multiElement
- *
- * @description
- * The `ngHide` directive shows or hides the given HTML element based on the expression provided to
- * the `ngHide` attribute.
- *
- * The element is shown or hidden by removing or adding the `.ng-hide` CSS class onto the element.
- * The `.ng-hide` CSS class is predefined in AngularJS and sets the display style to none (using an
- * `!important` flag). For CSP mode please add `angular-csp.css` to your HTML file (see
- * {@link ng.directive:ngCsp ngCsp}).
- *
- * ```html
- * 
- * 

- *
- * 
- * 

- * ```
- *
- * When the `ngHide` expression evaluates to a truthy value then the `.ng-hide` CSS class is added
- * to the class attribute on the element causing it to become hidden. When falsy, the `.ng-hide`
- * CSS class is removed from the element causing the element not to appear hidden.
- *
- * ## Why is `!important` used?
- *
- * You may be wondering why `!important` is used for the `.ng-hide` CSS class. This is because the
- * `.ng-hide` selector can be easily overridden by heavier selectors. For example, something as
- * simple as changing the display style on a HTML list item would make hidden elements appear
- * visible. This also becomes a bigger issue when dealing with CSS frameworks.
- *
- * By using `!important`, the show and hide behavior will work as expected despite any clash between
- * CSS selector specificity (when `!important` isn't used with any conflicting styles). If a
- * developer chooses to override the styling to change how to hide an element then it is just a
- * matter of using `!important` in their own CSS code.
- *
- * ### Overriding `.ng-hide`
- *
- * By default, the `.ng-hide` class will style the element with `display: none !important`. If you
- * wish to change the hide behavior with `ngShow`/`ngHide`, you can simply overwrite the styles for
- * the `.ng-hide` CSS class. Note that the selector that needs to be used is actually
- * `.ng-hide:not(.ng-hide-animate)` to cope with extra animation classes that can be added.
- *
- * ```css
- * .ng-hide:not(.ng-hide-animate) {
- *   /* These are just alternative ways of hiding an element */
- *   display: block!important;
- *   position: absolute;
- *   top: -9999px;
- *   left: -9999px;
- * }
- * ```
- *
- * By default you don't need to override in CSS anything and the animations will work around the
- * display style.
- *
- * @animations
- * | Animation                                           | Occurs                                                                                                     |
- * |-----------------------------------------------------|------------------------------------------------------------------------------------------------------------|
- * | {@link $animate#addClass addClass} `.ng-hide`       | After the `ngHide` expression evaluates to a truthy value and just before the contents are set to hidden.  |
- * | {@link $animate#removeClass removeClass} `.ng-hide` | After the `ngHide` expression evaluates to a non truthy value and just before contents are set to visible. |
- *
- * Animations in `ngShow`/`ngHide` work with the show and hide events that are triggered when the
- * directive expression is true and false. This system works like the animation system present with
- * `ngClass` except that you must also include the `!important` flag to override the display
- * property so that the elements are not actually hidden during the animation.
- *
- * ```css
- * /* A working example can be found at the bottom of this page. */
- * .my-element.ng-hide-add, .my-element.ng-hide-remove {
- *   transition: all 0.5s linear;
- * }
- *
- * .my-element.ng-hide-add { ... }
- * .my-element.ng-hide-add.ng-hide-add-active { ... }
- * .my-element.ng-hide-remove { ... }
- * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
- * ```
- *
- * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display property
- * to block during animation states - ngAnimate will automatically handle the style toggling for you.
- *
- * @element ANY
- * @param {expression} ngHide If the {@link guide/expression expression} is truthy/falsy then the
- *                            element is hidden/shown respectively.
- *
- * @example
- * A simple example, animating the element's opacity:
- *

-

-/**
- * @ngdoc directive
- * @name ngSwitch
- * @restrict EA
- *
- * @description
- * The `ngSwitch` directive is used to conditionally swap DOM structure on your template based on a scope expression.
- * Elements within `ngSwitch` but without `ngSwitchWhen` or `ngSwitchDefault` directives will be preserved at the location
- * as specified in the template.
- *
- * The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it
- * from the template cache), `ngSwitch` simply chooses one of the nested elements and makes it visible based on which element
- * matches the value obtained from the evaluated expression. In other words, you define a container element
- * (where you place the directive), place an expression on the **`on="..."` attribute**
- * (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place
- * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
- * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
- * attribute is displayed.
- *
- * 

- * Be aware that the attribute values to match against cannot be expressions. They are interpreted
- * as literal string values to match against.
- * For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the
- * value of the expression `$scope.someVal`.
- *

- * @animations
- * | Animation                        | Occurs                              |
- * |----------------------------------|-------------------------------------|
- * | {@link ng.$animate#enter enter}  | after the ngSwitch contents change and the matched child element is placed inside the container |
- * | {@link ng.$animate#leave leave}  | after the ngSwitch contents change and just before the former contents are removed from the DOM |

- *
- * @scope
- * @priority 1200
- * @param {*} ngSwitch|on expression to match against ng-switch-when.
- * On child elements add:
- *
- * * `ngSwitchWhen`: the case statement to match against. If match then this
- *   case will be displayed. If the same match appears multiple times, all the
- *   elements will be displayed. It is possible to associate multiple values to
- *   the same `ngSwitchWhen` by defining the optional attribute
- *   `ngSwitchWhenSeparator`. The separator will be used to split the value of
- *   the `ngSwitchWhen` attribute into multiple tokens, and the element will show
- *   if any of the `ngSwitch` evaluates to any of these tokens.
- * * `ngSwitchDefault`: the default case when no other case match. If there
- *   are multiple default cases, all of them will be displayed when no other
- *   case match.

+   * @multiElement
+   *
+   * @description
+   * The `ngShow` directive shows or hides the given HTML element based on the expression provided to
+   * the `ngShow` attribute.
+   *
+   * The element is shown or hidden by removing or adding the `.ng-hide` CSS class onto the element.
+   * The `.ng-hide` CSS class is predefined in AngularJS and sets the display style to none (using an
+   * `!important` flag). For CSP mode please add `angular-csp.css` to your HTML file (see
+   * {@link ng.directive:ngCsp ngCsp}).
+   *
+   * ```html
+   * 
+   * 

+   *
+   * 
+   * 

+   * ```
+   *
+   * When the `ngShow` expression evaluates to a falsy value then the `.ng-hide` CSS class is added
+   * to the class attribute on the element causing it to become hidden. When truthy, the `.ng-hide`
+   * CSS class is removed from the element causing the element not to appear hidden.
+   *
+   * ## Why is `!important` used?
+   *
+   * You may be wondering why `!important` is used for the `.ng-hide` CSS class. This is because the
+   * `.ng-hide` selector can be easily overridden by heavier selectors. For example, something as
+   * simple as changing the display style on a HTML list item would make hidden elements appear
+   * visible. This also becomes a bigger issue when dealing with CSS frameworks.
+   *
+   * By using `!important`, the show and hide behavior will work as expected despite any clash between
+   * CSS selector specificity (when `!important` isn't used with any conflicting styles). If a
+   * developer chooses to override the styling to change how to hide an element then it is just a
+   * matter of using `!important` in their own CSS code.
+   *
+   * ### Overriding `.ng-hide`
+   *
+   * By default, the `.ng-hide` class will style the element with `display: none !important`. If you
+   * wish to change the hide behavior with `ngShow`/`ngHide`, you can simply overwrite the styles for
+   * the `.ng-hide` CSS class. Note that the selector that needs to be used is actually
+   * `.ng-hide:not(.ng-hide-animate)` to cope with extra animation classes that can be added.
+   *
+   * ```css
+   * .ng-hide:not(.ng-hide-animate) {
+   *   /* These are just alternative ways of hiding an element */
+   *   display: block!important;
+   *   position: absolute;
+   *   top: -9999px;
+   *   left: -9999px;
+   * }
+   * ```
+   *
+   * By default you don't need to override anything in CSS and the animations will work around the
+   * display style.
+   *
+   * @animations
+   * | Animation                                           | Occurs                                                                                                        |
+   * |-----------------------------------------------------|---------------------------------------------------------------------------------------------------------------|
+   * | {@link $animate#addClass addClass} `.ng-hide`       | After the `ngShow` expression evaluates to a non truthy value and just before the contents are set to hidden. |
+   * | {@link $animate#removeClass removeClass} `.ng-hide` | After the `ngShow` expression evaluates to a truthy value and just before contents are set to visible.        |
+   *
+   * Animations in `ngShow`/`ngHide` work with the show and hide events that are triggered when the
+   * directive expression is true and false. This system works like the animation system present with
+   * `ngClass` except that you must also include the `!important` flag to override the display
+   * property so that the elements are not actually hidden during the animation.
+   *
+   * ```css
+   * /* A working example can be found at the bottom of this page. */
+   * .my-element.ng-hide-add, .my-element.ng-hide-remove {
+   *   transition: all 0.5s linear;
+   * }
+   *
+   * .my-element.ng-hide-add { ... }
+   * .my-element.ng-hide-add.ng-hide-add-active { ... }
+   * .my-element.ng-hide-remove { ... }
+   * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
+   * ```
+   *
+   * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display property
+   * to block during animation states - ngAnimate will automatically handle the style toggling for you.
+   *
+   * @element ANY
+   * @param {expression} ngShow If the {@link guide/expression expression} is truthy/falsy then the
+   *                            element is shown/hidden respectively.
+   *
+   * @example
+   * A simple example, animating the element's opacity:
+   *
+    
+      
+        Show: 

+        

+          I show up when your checkbox is checked.
+        

+      
+      
+        .animate-show-hide.ng-hide {
+          opacity: 0;
+        }
+  
+        .animate-show-hide.ng-hide-add,
+        .animate-show-hide.ng-hide-remove {
+          transition: all linear 0.5s;
+        }
+  
+        .check-element {
+          border: 1px solid black;
+          opacity: 1;
+          padding: 10px;

+          checkbox.click();
+          expect(checkElem.isDisplayed()).toBe(true);

+   * There are several way to mitigate this problem:
+   *
+   * - {@link guide/animations#how-to-selectively-enable-disable-and-skip-animations Disable animations on the affected elements}.
+   * - Use {@link ngIf} or {@link ngSwitch} instead of {@link ngShow} / {@link ngHide}.
+   * - Use the special CSS selector `ng-hide.ng-hide-animate` to set `{display: none}` or similar on the affected elements.
+   * - Use `ng-class="{'ng-hide': expression}` instead of instead of {@link ngShow} / {@link ngHide}.
+   * - Define an animation on the affected elements.

+   * Animations in `ngShow`/`ngHide` work with the show and hide events that are triggered when the
+   * directive expression is true and false. This system works like the animation system present with
+   * `ngClass` except that you must also include the `!important` flag to override the display
+   * property so that the elements are not actually hidden during the animation.
+   *
+   * ```css
+   * /* A working example can be found at the bottom of this page. */
+   * .my-element.ng-hide-add, .my-element.ng-hide-remove {
+   *   transition: all 0.5s linear;
+   * }
+   *
+   * .my-element.ng-hide-add { ... }
+   * .my-element.ng-hide-add.ng-hide-add-active { ... }
+   * .my-element.ng-hide-remove { ... }
+   * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
+   * ```
+   *
+   * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display property
+   * to block during animation states - ngAnimate will automatically handle the style toggling for you.

+   * ### Flickering when using ngHide to toggle between elements
+   *
+   * When using {@link ngShow} and / or {@link ngHide} to toggle between elements, it can
+   * happen that both the element to show and the element to hide are visible for a very short time.
+   *
+   * This usually happens when the {@link ngAnimate ngAnimate module} is included, but no actual animations
+   * are defined for {@link ngShow} / {@link ngHide}. Internet Explorer is affected more often than
+   * other browsers.
+   *
+   * There are several way to mitigate this problem:
+   *
+   * - {@link guide/animations#how-to-selectively-enable-disable-and-skip-animations Disable animations on the affected elements}.
+   * - Use {@link ngIf} or {@link ngSwitch} instead of {@link ngShow} / {@link ngHide}.
+   * - Use the special CSS selector `ng-hide.ng-hide-animate` to set `{display: none}` or similar on the affected elements.
+   * - Use `ng-class="{'ng-hide': expression}` instead of instead of {@link ngShow} / {@link ngHide}.
+   * - Define an animation on the affected elements.

+   *
+   * @description
+   * The `ngSwitch` directive is used to conditionally swap DOM structure on your template based on a scope expression.
+   * Elements within `ngSwitch` but without `ngSwitchWhen` or `ngSwitchDefault` directives will be preserved at the location
+   * as specified in the template.
+   *
+   * The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it
+   * from the template cache), `ngSwitch` simply chooses one of the nested elements and makes it visible based on which element
+   * matches the value obtained from the evaluated expression. In other words, you define a container element
+   * (where you place the directive), place an expression on the **`on="..."` attribute**
+   * (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place
+   * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
+   * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
+   * attribute is displayed.
+   *
+   * 

+   * Be aware that the attribute values to match against cannot be expressions. They are interpreted
+   * as literal string values to match against.
+   * For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the
+   * value of the expression `$scope.someVal`.
+   * 

+  
+   * @animations
+   * | Animation                        | Occurs                              |
+   * |----------------------------------|-------------------------------------|
+   * | {@link ng.$animate#enter enter}  | after the ngSwitch contents change and the matched child element is placed inside the container |
+   * | {@link ng.$animate#leave leave}  | after the ngSwitch contents change and just before the former contents are removed from the DOM |

+   *
+   * @scope

+   * @param {*} ngSwitch|on expression to match against ng-switch-when.
+   * On child elements add:
+   *
+   * * `ngSwitchWhen`: the case statement to match against. If match then this
+   *   case will be displayed. If the same match appears multiple times, all the
+   *   elements will be displayed. It is possible to associate multiple values to
+   *   the same `ngSwitchWhen` by defining the optional attribute
+   *   `ngSwitchWhenSeparator`. The separator will be used to split the value of
+   *   the `ngSwitchWhen` attribute into multiple tokens, and the element will show
+   *   if any of the `ngSwitch` evaluates to any of these tokens.
+   * * `ngSwitchDefault`: the default case when no other case match. If there
+   *   are multiple default cases, all of them will be displayed when no other
+   *   case match.

-/**
- * @ngdoc directive
- * @name ngTransclude
- * @restrict EAC
- *
- * @description
- * Directive that marks the insertion point for the transcluded DOM of the nearest parent directive that uses transclusion.
- *
- * You can specify that you want to insert a named transclusion slot, instead of the default slot, by providing the slot name
- * as the value of the `ng-transclude` or `ng-transclude-slot` attribute.
- *
- * If the transcluded content is not empty (i.e. contains one or more DOM nodes, including whitespace text nodes), any existing
- * content of this element will be removed before the transcluded content is inserted.
- * If the transcluded content is empty (or only whitespace), the existing content is left intact. This lets you provide fallback
- * content in the case that no transcluded content is provided.
- *
- * @element ANY
- *
- * @param {string} ngTransclude|ngTranscludeSlot the name of the slot to insert at this point. If this is not provided, is empty
- *                                               or its value is the same as the name of the attribute then the default slot is used.
- *
- * @example
- * ### Basic transclusion
- * This example demonstrates basic transclusion of content into a component directive.
- * 
- *   
- *     
- *     

- *        

- *        

- *       {{text}}
- *     

- *   
- *   
- *      it('should have transcluded', function() {
- *        var titleElement = element(by.model('title'));
- *        titleElement.clear();
- *        titleElement.sendKeys('TITLE');
- *        var textElement = element(by.model('text'));
- *        textElement.clear();
- *        textElement.sendKeys('TEXT');
- *        expect(element(by.binding('title')).getText()).toEqual('TITLE');
- *        expect(element(by.binding('text')).getText()).toEqual('TEXT');
- *      });
- *   
- * 
- *
- * @example
- * ### Transclude fallback content
- * This example shows how to use `NgTransclude` with fallback content, that
- * is displayed if no transcluded content is provided.
- *
- * 
- * 
- * 
- * 
- * 
- * 
- * 
- *   Button2
- * 
- *

- * {@link ng.ngOptions ngOptions} select element.
- *
- * @example
- * ### Set a custom error when the unknown option is selected
- *
- * This example sets a custom error "unknownValue" on the ngModelController
- * when the select element's unknown option is selected, i.e. when the model is set to a value
- * that is not matched by any option.
- *
- * 
- *

- *     

- *

- *    .controller('ExampleController', ['$scope', function($scope) {
- *      $scope.selected = null;
- *
- *      $scope.forceUnknownOption = function() {
- *        $scope.selected = 'nonsense';
- *      };

- * 
- *
- *
- *
- * @example
- * ### Set the "required" error when the unknown option is selected.
- *
- * By default, the "required" error on the ngModelController is only set on a required select
- * when the empty option is selected. This example adds a custom directive that also sets the
- * error when the unknown option is selected.

+   * @description
+   * The controller for the {@link ng.select select} directive. The controller exposes
+   * a few utility methods that can be used to augment the behavior of a regular or an
+   * {@link ng.ngOptions ngOptions} select element.
+   *
+   * @example
+   * ### Set a custom error when the unknown option is selected
+   *
+   * This example sets a custom error "unknownValue" on the ngModelController
+   * when the select element's unknown option is selected, i.e. when the model is set to a value
+   * that is not matched by any option.
+   *
+   * 
+   * 
+   * 

+   *   

+   *     

+   *     

+   *     
+   *       Error: The current model doesn't match any option

+   *
+   *     

+   *   

+   * 

+   * 
+   * 
+   *  angular.module('staticSelect', [])
+   *    .controller('ExampleController', ['$scope', function($scope) {
+   *      $scope.selected = null;
+   *
+   *      $scope.forceUnknownOption = function() {
+   *        $scope.selected = 'nonsense';
+   *      };
+   *   }])
+   *   .directive('unknownValueError', function() {
+   *     return {
+   *       require: ['ngModel', 'select'],
+   *       link: function(scope, element, attrs, ctrls) {
+   *         var ngModelCtrl = ctrls[0];
+   *         var selectCtrl = ctrls[1];
+   *
+   *         ngModelCtrl.$validators.unknownValue = function(modelValue, viewValue) {
+   *           if (selectCtrl.$isUnknownOptionSelected()) {
+   *             return false;
+   *           }
+   *
+   *           return true;
+   *         };
+   *       }
+   *
+   *     };
+   *   });
+   * 
+   *
+   *
+   *
+   * @example
+   * ### Set the "required" error when the unknown option is selected.
+   *
+   * By default, the "required" error on the ngModelController is only set on a required select
+   * when the empty option is selected. This example adds a custom directive that also sets the
+   * error when the unknown option is selected.
+   *

- * ngAnimateChildren allows you to specify that children of this element should animate even if any
- * of the children's parents are currently animating. By default, when an element has an active `enter`, `leave`, or `move`
- * (structural) animation, child elements that also have an active structural animation are not animated.
- *
- * Note that even if `ngAnimateChildren` is set, no child animations will run when the parent element is removed from the DOM (`leave` animation).
- *
- *
- * @param {string} ngAnimateChildren If the value is empty, `true` or `on`,
- *     then child animations are allowed. If the value is `false`, child animations are not allowed.

-/**
- * @ngdoc service
- * @name $animateCss
- * @kind object
- *
- * @description
- * The `$animateCss` service is a useful utility to trigger customized CSS-based transitions/keyframes
- * from a JavaScript-based animation or directly from a directive. The purpose of `$animateCss` is NOT
- * to side-step how `$animate` and ngAnimate work, but the goal is to allow pre-existing animations or
- * directives to create more complex animations that can be purely driven using CSS code.
- *
- * Note that only browsers that support CSS transitions and/or keyframe animations are capable of
- * rendering animations triggered via `$animateCss` (bad news for IE9 and lower).
- *
- * ## General Use
- * Once again, `$animateCss` is designed to be used inside of a registered JavaScript animation that
- * is powered by ngAnimate. It is possible to use `$animateCss` directly inside of a directive, however,
- * any automatic control over cancelling animations and/or preventing animations from being run on
- * child elements will not be handled by AngularJS. For this to work as expected, please use `$animate` to
- * trigger the animation and then setup a JavaScript animation that injects `$animateCss` to trigger
- * the CSS animation.
- *
- * The example below shows how we can create a folding animation on an element using `ng-if`:
- *
- * ```html
- * 
- * 

- *   This element will go BOOM
- * 

- * 
- * ```
- *
- * Now we create the **JavaScript animation** that will trigger the CSS transition:
- *
- * ```js
- * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
- *   return {
- *     enter: function(element, doneFn) {
- *       var height = element[0].offsetHeight;
- *       return $animateCss(element, {
- *         from: { height:'0px' },
- *         to: { height:height + 'px' },
- *         duration: 1 // one second
- *       });
- *     }
- *   }
- * }]);
- * ```
- *
- * ## More Advanced Uses
- *
- * `$animateCss` is the underlying code that ngAnimate uses to power **CSS-based animations** behind the scenes. Therefore CSS hooks
- * like `.ng-EVENT`, `.ng-EVENT-active`, `.ng-EVENT-stagger` are all features that can be triggered using `$animateCss` via JavaScript code.
- *
- * This also means that just about any combination of adding classes, removing classes, setting styles, dynamically setting a keyframe animation,
- * applying a hardcoded duration or delay value, changing the animation easing or applying a stagger animation are all options that work with
- * `$animateCss`. The service itself is smart enough to figure out the combination of options and examine the element styling properties in order
- * to provide a working animation that will run in CSS.
- *
- * The example below showcases a more advanced version of the `.fold-animation` from the example above:
- *
- * ```js
- * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
- *   return {
- *     enter: function(element, doneFn) {
- *       var height = element[0].offsetHeight;
- *       return $animateCss(element, {
- *         addClass: 'red large-text pulse-twice',
- *         easing: 'ease-out',
- *         from: { height:'0px' },
- *         to: { height:height + 'px' },
- *         duration: 1 // one second
- *       });
- *     }
- *   }
- * }]);
- * ```
- *
- * Since we're adding/removing CSS classes then the CSS transition will also pick those up:
- *
- * ```css
- * /* since a hardcoded duration value of 1 was provided in the JavaScript animation code,
- * the CSS classes below will be transitioned despite them being defined as regular CSS classes */
- * .red { background:red; }
- * .large-text { font-size:20px; }
- *
- * /* we can also use a keyframe animation and $animateCss will make it work alongside the transition */
- * .pulse-twice {
- *   animation: 0.5s pulse linear 2;
- *   -webkit-animation: 0.5s pulse linear 2;
- * }
- *
- * @keyframes pulse {
- *   from { transform: scale(0.5); }
- *   to { transform: scale(1.5); }
- * }
- *
- * @-webkit-keyframes pulse {
- *   from { -webkit-transform: scale(0.5); }
- *   to { -webkit-transform: scale(1.5); }
- * }
- * ```
- *
- * Given this complex combination of CSS classes, styles and options, `$animateCss` will figure everything out and make the animation happen.
- *
- * ## How the Options are handled
- *
- * `$animateCss` is very versatile and intelligent when it comes to figuring out what configurations to apply to the element to ensure the animation
- * works with the options provided. Say for example we were adding a class that contained a keyframe value and we wanted to also animate some inline
- * styles using the `from` and `to` properties.
- *
- * ```js
- * var animator = $animateCss(element, {
- *   from: { background:'red' },
- *   to: { background:'blue' }
- * });
- * animator.start();
- * ```
- *
- * ```css
- * .rotating-animation {
- *   animation:0.5s rotate linear;
- *   -webkit-animation:0.5s rotate linear;
- * }
- *
- * @keyframes rotate {
- *   from { transform: rotate(0deg); }
- *   to { transform: rotate(360deg); }
- * }
- *
- * @-webkit-keyframes rotate {
- *   from { -webkit-transform: rotate(0deg); }
- *   to { -webkit-transform: rotate(360deg); }
- * }
- * ```
- *
- * The missing pieces here are that we do not have a transition set (within the CSS code nor within the `$animateCss` options) and the duration of the animation is
- * going to be detected from what the keyframe styles on the CSS class are. In this event, `$animateCss` will automatically create an inline transition
- * style matching the duration detected from the keyframe style (which is present in the CSS class that is being added) and then prepare both the transition
- * and keyframe animations to run in parallel on the element. Then when the animation is underway the provided `from` and `to` CSS styles will be applied
- * and spread across the transition and keyframe animation.
- *
- * ## What is returned
- *
- * `$animateCss` works in two stages: a preparation phase and an animation phase. Therefore when `$animateCss` is first called it will NOT actually
- * start the animation. All that is going on here is that the element is being prepared for the animation (which means that the generated CSS classes are
- * added and removed on the element). Once `$animateCss` is called it will return an object with the following properties:
- *
- * ```js
- * var animator = $animateCss(element, { ... });
- * ```
- *
- * Now what do the contents of our `animator` variable look like:
- *
- * ```js
- * {
- *   // starts the animation
- *   start: Function,
- *
- *   // ends (aborts) the animation
- *   end: Function
- * }
- * ```
- *
- * To actually start the animation we need to run `animation.start()` which will then return a promise that we can hook into to detect when the animation ends.
- * If we choose not to run the animation then we MUST run `animation.end()` to perform a cleanup on the element (since some CSS classes and styles may have been
- * applied to the element during the preparation phase). Note that all other properties such as duration, delay, transitions and keyframes are just properties
- * and that changing them will not reconfigure the parameters of the animation.
- *
- * ### runner.done() vs runner.then()
- * It is documented that `animation.start()` will return a promise object and this is true, however, there is also an additional method available on the
- * runner called `.done(callbackFn)`. The done method works the same as `.finally(callbackFn)`, however, it does **not trigger a digest to occur**.
- * Therefore, for performance reasons, it's always best to use `runner.done(callback)` instead of `runner.then()`, `runner.catch()` or `runner.finally()`
- * unless you really need a digest to kick off afterwards.
- *
- * Keep in mind that, to make this easier, ngAnimate has tweaked the JS animations API to recognize when a runner instance is returned from $animateCss
- * (so there is no need to call `runner.done(doneFn)` inside of your JavaScript animation code).
- * Check the {@link ngAnimate.$animateCss#usage animation code above} to see how this works.
- *
- * @param {DOMElement} element the element that will be animated
- * @param {object} options the animation-related options that will be applied during the animation
- *
- * * `event` - The DOM event (e.g. enter, leave, move). When used, a generated CSS class of `ng-EVENT` and `ng-EVENT-active` will be applied
- * to the element during the animation. Multiple events can be provided when spaces are used as a separator. (Note that this will not perform any DOM operation.)
- * * `structural` - Indicates that the `ng-` prefix will be added to the event class. Setting to `false` or omitting will turn `ng-EVENT` and
- * `ng-EVENT-active` in `EVENT` and `EVENT-active`. Unused if `event` is omitted.
- * * `easing` - The CSS easing value that will be applied to the transition or keyframe animation (or both).
- * * `transitionStyle` - The raw CSS transition style that will be used (e.g. `1s linear all`).
- * * `keyframeStyle` - The raw CSS keyframe animation style that will be used (e.g. `1s my_animation linear`).
- * * `from` - The starting CSS styles (a key/value object) that will be applied at the start of the animation.
- * * `to` - The ending CSS styles (a key/value object) that will be applied across the animation via a CSS transition.
- * * `addClass` - A space separated list of CSS classes that will be added to the element and spread across the animation.
- * * `removeClass` - A space separated list of CSS classes that will be removed from the element and spread across the animation.
- * * `duration` - A number value representing the total duration of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `0`
- * is provided then the animation will be skipped entirely.
- * * `delay` - A number value representing the total delay of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `true` is
- * used then whatever delay value is detected from the CSS classes will be mirrored on the elements styles (e.g. by setting delay true then the style value
- * of the element will be `transition-delay: DETECTED_VALUE`). Using `true` is useful when you want the CSS classes and inline styles to all share the same
- * CSS delay value.
- * * `stagger` - A numeric time value representing the delay between successively animated elements
- * ({@link ngAnimate#css-staggering-animations Click here to learn how CSS-based staggering works in ngAnimate.})
- * * `staggerIndex` - The numeric index representing the stagger item (e.g. a value of 5 is equal to the sixth item in the stagger; therefore when a
- *   `stagger` option value of `0.1` is used then there will be a stagger delay of `600ms`)
- * * `applyClassesEarly` - Whether or not the classes being added or removed will be used when detecting the animation. This is set by `$animate` when enter/leave/move animations are fired to ensure that the CSS classes are resolved in time. (Note that this will prevent any transitions from occurring on the classes being added and removed.)
- * * `cleanupStyles` - Whether or not the provided `from` and `to` styles will be removed once
- *    the animation is closed. This is useful for when the styles are used purely for the sake of
- *    the animation and do not have a lasting visual effect on the element (e.g. a collapse and open animation).
- *    By default this value is set to `false`.
- *
- * @return {object} an object with start and end methods and details about the animation.
- *
- * * `start` - The method to start the animation. This will return a `Promise` when called.
- * * `end` - This method will cancel the animation and remove all applied CSS classes and styles.

+  /**
+   * @ngdoc service
+   * @name $animateCss
+   * @kind object
+   *
+   * @description
+   * The `$animateCss` service is a useful utility to trigger customized CSS-based transitions/keyframes
+   * from a JavaScript-based animation or directly from a directive. The purpose of `$animateCss` is NOT
+   * to side-step how `$animate` and ngAnimate work, but the goal is to allow pre-existing animations or
+   * directives to create more complex animations that can be purely driven using CSS code.
+   *
+   * Note that only browsers that support CSS transitions and/or keyframe animations are capable of
+   * rendering animations triggered via `$animateCss` (bad news for IE9 and lower).
+   *
+   * ## General Use
+   * Once again, `$animateCss` is designed to be used inside of a registered JavaScript animation that
+   * is powered by ngAnimate. It is possible to use `$animateCss` directly inside of a directive, however,
+   * any automatic control over cancelling animations and/or preventing animations from being run on
+   * child elements will not be handled by AngularJS. For this to work as expected, please use `$animate` to
+   * trigger the animation and then setup a JavaScript animation that injects `$animateCss` to trigger
+   * the CSS animation.
+   *
+   * The example below shows how we can create a folding animation on an element using `ng-if`:
+   *
+   * ```html
+   * 
+   * 

+   *   This element will go BOOM
+   * 

+   * 
+   * ```
+   *
+   * Now we create the **JavaScript animation** that will trigger the CSS transition:
+   *
+   * ```js
+   * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
+   *   return {
+   *     enter: function(element, doneFn) {
+   *       var height = element[0].offsetHeight;
+   *       return $animateCss(element, {
+   *         from: { height:'0px' },
+   *         to: { height:height + 'px' },
+   *         duration: 1 // one second
+   *       });
+   *     }
+   *   }
+   * }]);
+   * ```
+   *
+   * ## More Advanced Uses
+   *
+   * `$animateCss` is the underlying code that ngAnimate uses to power **CSS-based animations** behind the scenes. Therefore CSS hooks
+   * like `.ng-EVENT`, `.ng-EVENT-active`, `.ng-EVENT-stagger` are all features that can be triggered using `$animateCss` via JavaScript code.
+   *
+   * This also means that just about any combination of adding classes, removing classes, setting styles, dynamically setting a keyframe animation,
+   * applying a hardcoded duration or delay value, changing the animation easing or applying a stagger animation are all options that work with
+   * `$animateCss`. The service itself is smart enough to figure out the combination of options and examine the element styling properties in order
+   * to provide a working animation that will run in CSS.
+   *
+   * The example below showcases a more advanced version of the `.fold-animation` from the example above:
+   *
+   * ```js
+   * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
+   *   return {
+   *     enter: function(element, doneFn) {
+   *       var height = element[0].offsetHeight;
+   *       return $animateCss(element, {
+   *         addClass: 'red large-text pulse-twice',
+   *         easing: 'ease-out',
+   *         from: { height:'0px' },
+   *         to: { height:height + 'px' },
+   *         duration: 1 // one second
+   *       });
+   *     }
+   *   }
+   * }]);
+   * ```
+   *
+   * Since we're adding/removing CSS classes then the CSS transition will also pick those up:
+   *
+   * ```css
+   * /* since a hardcoded duration value of 1 was provided in the JavaScript animation code,
+   * the CSS classes below will be transitioned despite them being defined as regular CSS classes */
+   * .red { background:red; }
+   * .large-text { font-size:20px; }
+   *
+   * /* we can also use a keyframe animation and $animateCss will make it work alongside the transition */
+   * .pulse-twice {
+   *   animation: 0.5s pulse linear 2;
+   *   -webkit-animation: 0.5s pulse linear 2;
+   * }
+   *
+   * @keyframes pulse {
+   *   from { transform: scale(0.5); }
+   *   to { transform: scale(1.5); }
+   * }
+   *
+   * @-webkit-keyframes pulse {
+   *   from { -webkit-transform: scale(0.5); }
+   *   to { -webkit-transform: scale(1.5); }
+   * }
+   * ```
+   *
+   * Given this complex combination of CSS classes, styles and options, `$animateCss` will figure everything out and make the animation happen.
+   *
+   * ## How the Options are handled
+   *
+   * `$animateCss` is very versatile and intelligent when it comes to figuring out what configurations to apply to the element to ensure the animation
+   * works with the options provided. Say for example we were adding a class that contained a keyframe value and we wanted to also animate some inline
+   * styles using the `from` and `to` properties.
+   *
+   * ```js
+   * var animator = $animateCss(element, {
+   *   from: { background:'red' },
+   *   to: { background:'blue' }
+   * });
+   * animator.start();
+   * ```
+   *
+   * ```css
+   * .rotating-animation {
+   *   animation:0.5s rotate linear;
+   *   -webkit-animation:0.5s rotate linear;
+   * }
+   *
+   * @keyframes rotate {
+   *   from { transform: rotate(0deg); }
+   *   to { transform: rotate(360deg); }
+   * }
+   *
+   * @-webkit-keyframes rotate {
+   *   from { -webkit-transform: rotate(0deg); }
+   *   to { -webkit-transform: rotate(360deg); }
+   * }
+   * ```
+   *
+   * The missing pieces here are that we do not have a transition set (within the CSS code nor within the `$animateCss` options) and the duration of the animation is
+   * going to be detected from what the keyframe styles on the CSS class are. In this event, `$animateCss` will automatically create an inline transition
+   * style matching the duration detected from the keyframe style (which is present in the CSS class that is being added) and then prepare both the transition
+   * and keyframe animations to run in parallel on the element. Then when the animation is underway the provided `from` and `to` CSS styles will be applied
+   * and spread across the transition and keyframe animation.
+   *
+   * ## What is returned
+   *
+   * `$animateCss` works in two stages: a preparation phase and an animation phase. Therefore when `$animateCss` is first called it will NOT actually
+   * start the animation. All that is going on here is that the element is being prepared for the animation (which means that the generated CSS classes are
+   * added and removed on the element). Once `$animateCss` is called it will return an object with the following properties:
+   *
+   * ```js
+   * var animator = $animateCss(element, { ... });
+   * ```
+   *
+   * Now what do the contents of our `animator` variable look like:
+   *
+   * ```js
+   * {
+   *   // starts the animation
+   *   start: Function,
+   *
+   *   // ends (aborts) the animation
+   *   end: Function
+   * }
+   * ```
+   *
+   * To actually start the animation we need to run `animation.start()` which will then return a promise that we can hook into to detect when the animation ends.
+   * If we choose not to run the animation then we MUST run `animation.end()` to perform a cleanup on the element (since some CSS classes and styles may have been
+   * applied to the element during the preparation phase). Note that all other properties such as duration, delay, transitions and keyframes are just properties
+   * and that changing them will not reconfigure the parameters of the animation.
+   *
+   * ### runner.done() vs runner.then()
+   * It is documented that `animation.start()` will return a promise object and this is true, however, there is also an additional method available on the
+   * runner called `.done(callbackFn)`. The done method works the same as `.finally(callbackFn)`, however, it does **not trigger a digest to occur**.
+   * Therefore, for performance reasons, it's always best to use `runner.done(callback)` instead of `runner.then()`, `runner.catch()` or `runner.finally()`
+   * unless you really need a digest to kick off afterwards.
+   *
+   * Keep in mind that, to make this easier, ngAnimate has tweaked the JS animations API to recognize when a runner instance is returned from $animateCss
+   * (so there is no need to call `runner.done(doneFn)` inside of your JavaScript animation code).
+   * Check the {@link ngAnimate.$animateCss#usage animation code above} to see how this works.
+   *
+   * @param {DOMElement} element the element that will be animated
+   * @param {object} options the animation-related options that will be applied during the animation
+   *
+   * * `event` - The DOM event (e.g. enter, leave, move). When used, a generated CSS class of `ng-EVENT` and `ng-EVENT-active` will be applied
+   * to the element during the animation. Multiple events can be provided when spaces are used as a separator. (Note that this will not perform any DOM operation.)
+   * * `structural` - Indicates that the `ng-` prefix will be added to the event class. Setting to `false` or omitting will turn `ng-EVENT` and
+   * `ng-EVENT-active` in `EVENT` and `EVENT-active`. Unused if `event` is omitted.
+   * * `easing` - The CSS easing value that will be applied to the transition or keyframe animation (or both).
+   * * `transitionStyle` - The raw CSS transition style that will be used (e.g. `1s linear all`).
+   * * `keyframeStyle` - The raw CSS keyframe animation style that will be used (e.g. `1s my_animation linear`).
+   * * `from` - The starting CSS styles (a key/value object) that will be applied at the start of the animation.
+   * * `to` - The ending CSS styles (a key/value object) that will be applied across the animation via a CSS transition.
+   * * `addClass` - A space separated list of CSS classes that will be added to the element and spread across the animation.
+   * * `removeClass` - A space separated list of CSS classes that will be removed from the element and spread across the animation.
+   * * `duration` - A number value representing the total duration of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `0`
+   * is provided then the animation will be skipped entirely.
+   * * `delay` - A number value representing the total delay of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `true` is
+   * used then whatever delay value is detected from the CSS classes will be mirrored on the elements styles (e.g. by setting delay true then the style value
+   * of the element will be `transition-delay: DETECTED_VALUE`). Using `true` is useful when you want the CSS classes and inline styles to all share the same
+   * CSS delay value.
+   * * `stagger` - A numeric time value representing the delay between successively animated elements
+   * ({@link ngAnimate#css-staggering-animations Click here to learn how CSS-based staggering works in ngAnimate.})
+   * * `staggerIndex` - The numeric index representing the stagger item (e.g. a value of 5 is equal to the sixth item in the stagger; therefore when a
+   *   `stagger` option value of `0.1` is used then there will be a stagger delay of `600ms`)
+   * * `applyClassesEarly` - Whether or not the classes being added or removed will be used when detecting the animation. This is set by `$animate` when enter/leave/move animations are fired to ensure that the CSS classes are resolved in time. (Note that this will prevent any transitions from occurring on the classes being added and removed.)

- * @restrict A
- * @scope
- *
- * @description
- *
- * ngAnimateSwap is a animation-oriented directive that allows for the container to
- * be removed and entered in whenever the associated expression changes. A
- * common usecase for this directive is a rotating banner or slider component which
- * contains one image being present at a time. When the active image changes
- * then the old image will perform a `leave` animation and the new element
- * will be inserted via an `enter` animation.
- *
- * @animations
- * | Animation                        | Occurs                               |
- * |----------------------------------|--------------------------------------|
- * | {@link ng.$animate#enter enter}  | when the new element is inserted to the DOM  |
- * | {@link ng.$animate#leave leave}  | when the old element is removed from the DOM |
- *
- * @example
- * 
- *   
- *     

- *       

- *         {{ number }}
- *

-/**
- * @ngdoc module
- * @name ngAnimate
- * @description
- *
- * The `ngAnimate` module provides support for CSS-based animations (keyframes and transitions) as well as JavaScript-based animations via
- * callback hooks. Animations are not enabled by default, however, by including `ngAnimate` the animation hooks are enabled for an AngularJS app.
- *
- * ## Usage
- * Simply put, there are two ways to make use of animations when ngAnimate is used: by using **CSS** and **JavaScript**. The former works purely based
- * using CSS (by using matching CSS selectors/styles) and the latter triggers animations that are registered via `module.animation()`. For
- * both CSS and JS animations the sole requirement is to have a matching `CSS class` that exists both in the registered animation and within
- * the HTML element that the animation will be triggered on.
- *
- * ## Directive Support
- * The following directives are "animation aware":
- *
- * | Directive                                                                     | Supported Animations                                                      |
- * |-------------------------------------------------------------------------------|---------------------------------------------------------------------------|
- * | {@link ng.directive:form#animations form / ngForm}                            | add and remove ({@link ng.directive:form#css-classes various classes})    |
- * | {@link ngAnimate.directive:ngAnimateSwap#animations ngAnimateSwap}            | enter and leave                                                           |
- * | {@link ng.directive:ngClass#animations ngClass / {{class}​}}  | add and remove                                                            |
- * | {@link ng.directive:ngClassEven#animations ngClassEven}                       | add and remove                                                            |
- * | {@link ng.directive:ngClassOdd#animations ngClassOdd}                         | add and remove                                                            |
- * | {@link ng.directive:ngHide#animations ngHide}                                 | add and remove (the `ng-hide` class)                                      |
- * | {@link ng.directive:ngIf#animations ngIf}                                     | enter and leave                                                           |
- * | {@link ng.directive:ngInclude#animations ngInclude}                           | enter and leave                                                           |
- * | {@link module:ngMessages#animations ngMessage / ngMessageExp}                 | enter and leave                                                           |
- * | {@link module:ngMessages#animations ngMessages}                               | add and remove (the `ng-active`/`ng-inactive` classes)                    |
- * | {@link ng.directive:ngModel#animations ngModel}                               | add and remove ({@link ng.directive:ngModel#css-classes various classes}) |
- * | {@link ng.directive:ngRepeat#animations ngRepeat}                             | enter, leave, and move                                                    |
- * | {@link ng.directive:ngShow#animations ngShow}                                 | add and remove (the `ng-hide` class)                                      |
- * | {@link ng.directive:ngSwitch#animations ngSwitch}                             | enter and leave                                                           |
- * | {@link ngRoute.directive:ngView#animations ngView}                            | enter and leave                                                           |
- *
- * (More information can be found by visiting the documentation associated with each directive.)
- *
- * For a full breakdown of the steps involved during each animation event, refer to the
- * {@link ng.$animate `$animate` API docs}.
- *
- * ## CSS-based Animations
- *
- * CSS-based animations with ngAnimate are unique since they require no JavaScript code at all. By using a CSS class that we reference between our HTML
- * and CSS code we can create an animation that will be picked up by AngularJS when an underlying directive performs an operation.
- *
- * The example below shows how an `enter` animation can be made possible on an element using `ng-if`:
- *
- * ```html
- * 

- *    Fade me in out
- * 

- * 
- * 
- * ```
- *
- * Notice the CSS class **fade**? We can now create the CSS transition code that references this class:
- *
- * ```css
- * /* The starting CSS styles for the enter animation */
- * .fade.ng-enter {
- *   transition:0.5s linear all;
- *   opacity:0;
- * }
- *
- * /* The finishing CSS styles for the enter animation */
- * .fade.ng-enter.ng-enter-active {
- *   opacity:1;
- * }
- * ```
- *
- * The key thing to remember here is that, depending on the animation event (which each of the directives above trigger depending on what's going on) two
- * generated CSS classes will be applied to the element; in the example above we have `.ng-enter` and `.ng-enter-active`. For CSS transitions, the transition
- * code **must** be defined within the starting CSS class (in this case `.ng-enter`). The destination class is what the transition will animate towards.
- *
- * If for example we wanted to create animations for `leave` and `move` (ngRepeat triggers move) then we can do so using the same CSS naming conventions:
- *
- * ```css
- * /* now the element will fade out before it is removed from the DOM */
- * .fade.ng-leave {
- *   transition:0.5s linear all;
- *   opacity:1;
- * }
- * .fade.ng-leave.ng-leave-active {
- *   opacity:0;
- * }
- * ```
- *
- * We can also make use of **CSS Keyframes** by referencing the keyframe animation within the starting CSS class:
- *
- * ```css
- * /* there is no need to define anything inside of the destination
- * CSS class since the keyframe will take charge of the animation */
- * .fade.ng-leave {
- *   animation: my_fade_animation 0.5s linear;
- *   -webkit-animation: my_fade_animation 0.5s linear;
- * }
- *
- * @keyframes my_fade_animation {
- *   from { opacity:1; }
- *   to { opacity:0; }
- * }
- *
- * @-webkit-keyframes my_fade_animation {
- *   from { opacity:1; }
- *   to { opacity:0; }
- * }
- * ```
- *
- * Feel free also mix transitions and keyframes together as well as any other CSS classes on the same element.
- *
- * ### CSS Class-based Animations
- *
- * Class-based animations (animations that are triggered via `ngClass`, `ngShow`, `ngHide` and some other directives) have a slightly different
- * naming convention. Class-based animations are basic enough that a standard transition or keyframe can be referenced on the class being added
- * and removed.
- *
- * For example if we wanted to do a CSS animation for `ngHide` then we place an animation on the `.ng-hide` CSS class:
- *
- * ```html
- * 

- *   Show and hide me
- * 

- * 
- *
- * 
- * ```
- *
- * All that is going on here with ngShow/ngHide behind the scenes is the `.ng-hide` class is added/removed (when the hidden state is valid). Since
- * ngShow and ngHide are animation aware then we can match up a transition and ngAnimate handles the rest.
- *
- * In addition the addition and removal of the CSS class, ngAnimate also provides two helper methods that we can use to further decorate the animation
- * with CSS styles.
- *
- * ```html
- * 

- *   Highlight this box
- * 

- * 
- *
- * 
- * ```
- *
- * We can also make use of CSS keyframes by placing them within the CSS classes.
- *
- *
- * ### CSS Staggering Animations
- * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a
- * curtain-like effect. The ngAnimate module (versions >=1.2) supports staggering animations and the stagger effect can be
- * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for
- * the animation. The style property expected within the stagger class can either be a **transition-delay** or an
- * **animation-delay** property (or both if your animation contains both transitions and keyframe animations).
- *
- * ```css
- * .my-animation.ng-enter {
- *   /* standard transition code */
- *   transition: 1s linear all;
- *   opacity:0;
- * }
- * .my-animation.ng-enter-stagger {
- *   /* this will have a 100ms delay between each successive leave animation */
- *   transition-delay: 0.1s;
- *
- *   /* As of 1.4.4, this must always be set: it signals ngAnimate
- *     to not accidentally inherit a delay property from another CSS class */
- *   transition-duration: 0s;
- *
- *   /* if you are using animations instead of transitions you should configure as follows:
- *     animation-delay: 0.1s;
- *     animation-duration: 0s; */
- * }
- * .my-animation.ng-enter.ng-enter-active {
- *   /* standard transition styles */
- *   opacity:1;
- * }
- * ```
- *
- * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations
- * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this
- * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation
- * will also be reset if one or more animation frames have passed since the multiple calls to `$animate` were fired.
- *
- * The following code will issue the **ng-leave-stagger** event on the element provided:
- *
- * ```js
- * var kids = parent.children();
- *
- * $animate.leave(kids[0]); //stagger index=0
- * $animate.leave(kids[1]); //stagger index=1
- * $animate.leave(kids[2]); //stagger index=2
- * $animate.leave(kids[3]); //stagger index=3
- * $animate.leave(kids[4]); //stagger index=4
- *
- * window.requestAnimationFrame(function() {
- *   //stagger has reset itself
- *   $animate.leave(kids[5]); //stagger index=0
- *   $animate.leave(kids[6]); //stagger index=1
- *
- *   $scope.$digest();
- * });
- * ```
- *
- * Stagger animations are currently only supported within CSS-defined animations.
- *
- * ### The `ng-animate` CSS class
- *
- * When ngAnimate is animating an element it will apply the `ng-animate` CSS class to the element for the duration of the animation.
- * This is a temporary CSS class and it will be removed once the animation is over (for both JavaScript and CSS-based animations).
- *
- * Therefore, animations can be applied to an element using this temporary class directly via CSS.
- *
- * ```css
- * .zipper.ng-animate {
- *   transition:0.5s linear all;
- * }
- * .zipper.ng-enter {
- *   opacity:0;
- * }
- * .zipper.ng-enter.ng-enter-active {
- *   opacity:1;
- * }
- * .zipper.ng-leave {
- *   opacity:1;
- * }
- * .zipper.ng-leave.ng-leave-active {
- *   opacity:0;
- * }
- * ```
- *
- * (Note that the `ng-animate` CSS class is reserved and it cannot be applied on an element directly since ngAnimate will always remove
- * the CSS class once an animation has completed.)
- *
- *
- * ### The `ng-[event]-prepare` class
- *
- * This is a special class that can be used to prevent unwanted flickering / flash of content before
- * the actual animation starts. The class is added as soon as an animation is initialized, but removed
- * before the actual animation starts (after waiting for a $digest).
- * It is also only added for *structural* animations (`enter`, `move`, and `leave`).
- *
- * In practice, flickering can appear when nesting elements with structural animations such as `ngIf`
- * into elements that have class-based animations such as `ngClass`.
- *
- * ```html
- * 

- *   

- *     

- *   

- * 

- * ```
- *
- * It is possible that during the `enter` animation, the `.message` div will be briefly visible before it starts animating.
- * In that case, you can add styles to the CSS that make sure the element stays hidden before the animation starts:
- *
- * ```css
- * .message.ng-enter-prepare {
- *   opacity: 0;
- * }
- * ```
- *
- * ### Animating between value changes
- *
- * Sometimes you need to animate between different expression states, whose values
- * don't necessary need to be known or referenced in CSS styles.
- * Unless possible with another {@link ngAnimate#directive-support "animation aware" directive},
- * that specific use case can always be covered with {@link ngAnimate.directive:ngAnimateSwap} as
- * can be seen in {@link ngAnimate.directive:ngAnimateSwap#examples this example}.
- *
- * Note that {@link ngAnimate.directive:ngAnimateSwap} is a *structural directive*, which means it
- * creates a new instance of the element (including any other/child directives it may have) and
- * links it to a new scope every time *swap* happens. In some cases this might not be desirable
- * (e.g. for performance reasons, or when you wish to retain internal state on the original
- * element instance).
- *
- * ## JavaScript-based Animations
- *
- * ngAnimate also allows for animations to be consumed by JavaScript code. The approach is similar to CSS-based animations (where there is a shared
- * CSS class that is referenced in our HTML code) but in addition we need to register the JavaScript animation on the module. By making use of the
- * `module.animation()` module function we can register the animation.
- *
- * Let's see an example of a enter/leave animation using `ngRepeat`:
- *
- * ```html
- * 

- *   {{ item }}
- * 

- * ```
- *
- * See the **slide** CSS class? Let's use that class to define an animation that we'll structure in our module code by using `module.animation`:
- *
- * ```js
- * myModule.animation('.slide', [function() {
- *   return {
- *     // make note that other events (like addClass/removeClass)
- *     // have different function input parameters
- *     enter: function(element, doneFn) {
- *       jQuery(element).fadeIn(1000, doneFn);
- *
- *       // remember to call doneFn so that AngularJS
- *       // knows that the animation has concluded
- *     },
- *
- *     move: function(element, doneFn) {
- *       jQuery(element).fadeIn(1000, doneFn);
- *     },
- *
- *     leave: function(element, doneFn) {
- *       jQuery(element).fadeOut(1000, doneFn);
- *     }
- *   }
- * }]);
- * ```
- *
- * The nice thing about JS-based animations is that we can inject other services and make use of advanced animation libraries such as
- * greensock.js and velocity.js.
- *
- * If our animation code class-based (meaning that something like `ngClass`, `ngHide` and `ngShow` triggers it) then we can still define
- * our animations inside of the same registered animation, however, the function input arguments are a bit different:
- *
- * ```html
- * 

- *   this box is moody
- * 

- * 
- * 
- * 
- * ```
- *
- * ```js
- * myModule.animation('.colorful', [function() {
- *   return {
- *     addClass: function(element, className, doneFn) {
- *       // do some cool animation and call the doneFn
- *     },
- *     removeClass: function(element, className, doneFn) {
- *       // do some cool animation and call the doneFn
- *     },
- *     setClass: function(element, addedClass, removedClass, doneFn) {
- *       // do some cool animation and call the doneFn
- *     }
- *   }
- * }]);
- * ```
- *
- * ## CSS + JS Animations Together
- *
- * AngularJS 1.4 and higher has taken steps to make the amalgamation of CSS and JS animations more flexible. However, unlike earlier versions of AngularJS,
- * defining CSS and JS animations to work off of the same CSS class will not work anymore. Therefore the example below will only result in **JS animations taking
- * charge of the animation**:
- *
- * ```html
- * 

- *   Slide in and out
- * 

- * ```
- *
- * ```js
- * myModule.animation('.slide', [function() {
- *   return {
- *     enter: function(element, doneFn) {
- *       jQuery(element).slideIn(1000, doneFn);
- *     }
- *   }
- * }]);
- * ```
- *
- * ```css
- * .slide.ng-enter {
- *   transition:0.5s linear all;
- *   transform:translateY(-100px);
- * }
- * .slide.ng-enter.ng-enter-active {
- *   transform:translateY(0);
- * }
- * ```
- *
- * Does this mean that CSS and JS animations cannot be used together? Do JS-based animations always have higher priority? We can make up for the
- * lack of CSS animations by using the `$animateCss` service to trigger our own tweaked-out, CSS-based animations directly from
- * our own JS-based animation code:
- *
- * ```js
- * myModule.animation('.slide', ['$animateCss', function($animateCss) {
- *   return {
- *     enter: function(element) {
-*        // this will trigger `.slide.ng-enter` and `.slide.ng-enter-active`.
- *       return $animateCss(element, {
- *         event: 'enter',
- *         structural: true
- *       });
- *     }
- *   }
- * }]);
- * ```
- *
- * The nice thing here is that we can save bandwidth by sticking to our CSS-based animation code and we don't need to rely on a 3rd-party animation framework.
- *
- * The `$animateCss` service is very powerful since we can feed in all kinds of extra properties that will be evaluated and fed into a CSS transition or
- * keyframe animation. For example if we wanted to animate the height of an element while adding and removing classes then we can do so by providing that
- * data into `$animateCss` directly:
- *
- * ```js
- * myModule.animation('.slide', ['$animateCss', function($animateCss) {
- *   return {
- *     enter: function(element) {
- *       return $animateCss(element, {
- *         event: 'enter',
- *         structural: true,
- *         addClass: 'maroon-setting',
- *         from: { height:0 },
- *         to: { height: 200 }
- *       });
- *     }
- *   }
- * }]);
- * ```
- *
- * Now we can fill in the rest via our transition CSS code:
- *
- * ```css
- * /* the transition tells ngAnimate to make the animation happen */
- * .slide.ng-enter { transition:0.5s linear all; }
- *
- * /* this extra CSS class will be absorbed into the transition
- * since the $animateCss code is adding the class */
- * .maroon-setting { background:red; }
- * ```
- *
- * And `$animateCss` will figure out the rest. Just make sure to have the `done()` callback fire the `doneFn` function to signal when the animation is over.
- *
- * To learn more about what's possible be sure to visit the {@link ngAnimate.$animateCss $animateCss service}.
- *
- * ## Animation Anchoring (via `ng-animate-ref`)
- *
- * ngAnimate in AngularJS 1.4 comes packed with the ability to cross-animate elements between
- * structural areas of an application (like views) by pairing up elements using an attribute
- * called `ng-animate-ref`.
- *
- * Let's say for example we have two views that are managed by `ng-view` and we want to show
- * that there is a relationship between two components situated in within these views. By using the
- * `ng-animate-ref` attribute we can identify that the two components are paired together and we
- * can then attach an animation, which is triggered when the view changes.
- *
- * Say for example we have the following template code:
- *
- * ```html
- * 
- * 

- * 

- *
- * 
- * 
- *   
- * 
- *
- * 
- * 
- * ```
- *
- * Now, when the view changes (once the link is clicked), ngAnimate will examine the
- * HTML contents to see if there is a match reference between any components in the view
- * that is leaving and the view that is entering. It will scan both the view which is being
- * removed (leave) and inserted (enter) to see if there are any paired DOM elements that
- * contain a matching ref value.
- *
- * The two images match since they share the same ref value. ngAnimate will now create a
- * transport element (which is a clone of the first image element) and it will then attempt
- * to animate to the position of the second image element in the next view. For the animation to
- * work a special CSS class called `ng-anchor` will be added to the transported element.
- *
- * We can now attach a transition onto the `.banner.ng-anchor` CSS class and then
- * ngAnimate will handle the entire transition for us as well as the addition and removal of
- * any changes of CSS classes between the elements:
- *
- * ```css
- * .banner.ng-anchor {
- *   /* this animation will last for 1 second since there are
- *          two phases to the animation (an `in` and an `out` phase) */
- *   transition:0.5s linear all;
- * }
- * ```
- *
- * We also **must** include animations for the views that are being entered and removed
- * (otherwise anchoring wouldn't be possible since the new view would be inserted right away).
- *
- * ```css
- * .view-animation.ng-enter, .view-animation.ng-leave {
- *   transition:0.5s linear all;
- *   position:fixed;
- *   left:0;
- *   top:0;
- *   width:100%;
- * }
- * .view-animation.ng-enter {
- *   transform:translateX(100%);
- * }
- * .view-animation.ng-leave,
- * .view-animation.ng-enter.ng-enter-active {
- *   transform:translateX(0%);
- * }
- * .view-animation.ng-leave.ng-leave-active {
- *   transform:translateX(-100%);
- * }
- * ```
- *
- * Now we can jump back to the anchor animation. When the animation happens, there are two stages that occur:
- * an `out` and an `in` stage. The `out` stage happens first and that is when the element is animated away
- * from its origin. Once that animation is over then the `in` stage occurs which animates the
- * element to its destination. The reason why there are two animations is to give enough time
- * for the enter animation on the new element to be ready.
- *
- * The example above sets up a transition for both the in and out phases, but we can also target the out or
- * in phases directly via `ng-anchor-out` and `ng-anchor-in`.
- *
- * ```css
- * .banner.ng-anchor-out {
- *   transition: 0.5s linear all;
- *
- *   /* the scale will be applied during the out animation,
- *          but will be animated away when the in animation runs */
- *   transform: scale(1.2);
- * }
- *
- * .banner.ng-anchor-in {
- *   transition: 1s linear all;
- * }
- * ```
- *
- *
- *

- * ### How is the element transported?
- *
- * When an anchor animation occurs, ngAnimate will clone the starting element and position it exactly where the starting
- * element is located on screen via absolute positioning. The cloned element will be placed inside of the root element
- * of the application (where ng-app was defined) and all of the CSS classes of the starting element will be applied. The
- * element will then animate into the `out` and `in` animations and will eventually reach the coordinates and match
- * the dimensions of the destination element. During the entire animation a CSS class of `.ng-animate-shim` will be applied
- * to both the starting and destination elements in order to hide them from being visible (the CSS styling for the class
- * is: `visibility:hidden`). Once the anchor reaches its destination then it will be removed and the destination element
- * will become visible since the shim class will be removed.
- *
- * ### How is the morphing handled?
- *
- * CSS Anchoring relies on transitions and keyframes and the internal code is intelligent enough to figure out
- * what CSS classes differ between the starting element and the destination element. These different CSS classes
- * will be added/removed on the anchor element and a transition will be applied (the transition that is provided
- * in the anchor class). Long story short, ngAnimate will figure out what classes to add and remove which will
- * make the transition of the element as smooth and automatic as possible. Be sure to use simple CSS classes that
- * do not rely on DOM nesting structure so that the anchor element appears the same as the starting element (since
- * the cloned element is placed inside of root element which is likely close to the body element).
- *
- * Note that if the root element is on the `` element then the cloned node will be placed inside of body.
- *
- *
- * ## Using $animate in your directive code
- *
- * So far we've explored how to feed in animations into an AngularJS application, but how do we trigger animations within our own directives in our application?
- * By injecting the `$animate` service into our directive code, we can trigger structural and class-based hooks which can then be consumed by animations. Let's
- * imagine we have a greeting box that shows and hides itself when the data changes
- *
- * ```html
- * Hi there
- * ```
- *
- * ```js
- * ngModule.directive('greetingBox', ['$animate', function($animate) {
- *   return function(scope, element, attrs) {
- *     attrs.$observe('active', function(value) {
- *       value ? $animate.addClass(element, 'on') : $animate.removeClass(element, 'on');
- *     });
- *   });
- * }]);
- * ```
- *
- * Now the `on` CSS class is added and removed on the greeting box component. Now if we add a CSS class on top of the greeting box element
- * in our HTML code then we can trigger a CSS or JS animation to happen.
- *
- * ```css
- * /* normally we would create a CSS class to reference on the element */
- * greeting-box.on { transition:0.5s linear all; background:green; color:white; }
- * ```
- *
- * The `$animate` service contains a variety of other methods like `enter`, `leave`, `animate` and `setClass`. To learn more about what's
- * possible be sure to visit the {@link ng.$animate $animate service API page}.
- *
- *
- * ## Callbacks and Promises
- *
- * When `$animate` is called it returns a promise that can be used to capture when the animation has ended. Therefore if we were to trigger
- * an animation (within our directive code) then we can continue performing directive and scope related activities after the animation has
- * ended by chaining onto the returned promise that animation method returns.
- *
- * ```js
- * // somewhere within the depths of the directive
- * $animate.enter(element, parent).then(function() {
- *   //the animation has completed
- * });
- * ```
- *
- * (Note that earlier versions of AngularJS prior to v1.4 required the promise code to be wrapped using `$scope.$apply(...)`. This is not the case
- * anymore.)
- *
- * In addition to the animation promise, we can also make use of animation-related callbacks within our directives and controller code by registering
- * an event listener using the `$animate` service. Let's say for example that an animation was triggered on our view
- * routing controller to hook into that:
- *
- * ```js
- * ngModule.controller('HomePageController', ['$animate', function($animate) {
- *   $animate.on('enter', ngViewElement, function(element) {
- *     // the animation for this route has completed
- *   }]);
- * }])
- * ```
- *
- * (Note that you will need to trigger a digest within the callback to get AngularJS to notice any scope-related changes.)

   /**
-   * @ngdoc method
-   * @name $sanitizeProvider#enableSvg
-   * @kind function
-   *
+   * @ngdoc module
+   * @name ngAnimate
    * @description
-   * Enables a subset of svg to be supported by the sanitizer.
    *
-   * 

-   *   
By enabling this setting without taking other precautions, you might expose your
-   *   application to click-hijacking attacks. In these attacks, sanitized svg elements could be positioned
-   *   outside of the containing element and be rendered over other elements on the page (e.g. a login
-   *   link). Such behavior can then result in phishing incidents.

+   * The `ngAnimate` module provides support for CSS-based animations (keyframes and transitions) as well as JavaScript-based animations via
+   * callback hooks. Animations are not enabled by default, however, by including `ngAnimate` the animation hooks are enabled for an AngularJS app.
+   *
+   * ## Usage
+   * Simply put, there are two ways to make use of animations when ngAnimate is used: by using **CSS** and **JavaScript**. The former works purely based
+   * using CSS (by using matching CSS selectors/styles) and the latter triggers animations that are registered via `module.animation()`. For
+   * both CSS and JS animations the sole requirement is to have a matching `CSS class` that exists both in the registered animation and within
+   * the HTML element that the animation will be triggered on.
+   *
+   * ## Directive Support
+   * The following directives are "animation aware":
+   *
+   * | Directive                                                                     | Supported Animations                                                      |
+   * |-------------------------------------------------------------------------------|---------------------------------------------------------------------------|

+   * | {@link ngAnimate.directive:ngAnimateSwap#animations ngAnimateSwap}            | enter and leave                                                           |

+   * | {@link ng.directive:ngHide#animations ngHide}                                 | add and remove (the `ng-hide` class)                                      |
+   * | {@link ng.directive:ngIf#animations ngIf}                                     | enter and leave                                                           |

+   * | {@link ng.directive:ngModel#animations ngModel}                               | add and remove ({@link ng.directive:ngModel#css-classes various classes}) |
+   * | {@link ng.directive:ngRepeat#animations ngRepeat}                             | enter, leave, and move                                                    |
+   * | {@link ng.directive:ngShow#animations ngShow}                                 | add and remove (the `ng-hide` class)                                      |
+   * | {@link ng.directive:ngSwitch#animations ngSwitch}                             | enter and leave                                                           |
+   * | {@link ngRoute.directive:ngView#animations ngView}                            | enter and leave                                                           |
+   *
+   * (More information can be found by visiting the documentation associated with each directive.)
+   *
+   * For a full breakdown of the steps involved during each animation event, refer to the
+   * {@link ng.$animate `$animate` API docs}.
+   *
+   * ## CSS-based Animations
+   *
+   * CSS-based animations with ngAnimate are unique since they require no JavaScript code at all. By using a CSS class that we reference between our HTML
+   * and CSS code we can create an animation that will be picked up by AngularJS when an underlying directive performs an operation.
+   *
+   * The example below shows how an `enter` animation can be made possible on an element using `ng-if`:
+   *
+   * ```html
+   * 

+   *    Fade me in out
+   * 

+   * 
+   * 
+   * ```
    *
-   *   
To protect against these, explicitly setup `overflow: hidden` css rule for all potential svg
-   *   tags within the sanitized content:

+   * Notice the CSS class **fade**? We can now create the CSS transition code that references this class:
    *
-   *   

+   * ```css
+   * /* The starting CSS styles for the enter animation */
+   * .fade.ng-enter {
+   *   transition:0.5s linear all;
+   *   opacity:0;
+   * }
    *
-   *   

-   *   .rootOfTheIncludedContent svg {
-   *     overflow: hidden !important;
-   *   }
-   *   

+   * /* The finishing CSS styles for the enter animation */
+   * .fade.ng-enter.ng-enter-active {
+   *   opacity:1;
+   * }
+   * ```
+   *
+   * The key thing to remember here is that, depending on the animation event (which each of the directives above trigger depending on what's going on) two
+   * generated CSS classes will be applied to the element; in the example above we have `.ng-enter` and `.ng-enter-active`. For CSS transitions, the transition
+   * code **must** be defined within the starting CSS class (in this case `.ng-enter`). The destination class is what the transition will animate towards.
+   *
+   * If for example we wanted to create animations for `leave` and `move` (ngRepeat triggers move) then we can do so using the same CSS naming conventions:
+   *
+   * ```css
+   * /* now the element will fade out before it is removed from the DOM */
+   * .fade.ng-leave {
+   *   transition:0.5s linear all;
+   *   opacity:1;
+   * }
+   * .fade.ng-leave.ng-leave-active {
+   *   opacity:0;
+   * }
+   * ```
+   *
+   * We can also make use of **CSS Keyframes** by referencing the keyframe animation within the starting CSS class:
+   *
+   * ```css
+   * /* there is no need to define anything inside of the destination
+   * CSS class since the keyframe will take charge of the animation */
+   * .fade.ng-leave {
+   *   animation: my_fade_animation 0.5s linear;
+   *   -webkit-animation: my_fade_animation 0.5s linear;
+   * }
+   *
+   * @keyframes my_fade_animation {
+   *   from { opacity:1; }
+   *   to { opacity:0; }
+   * }
+   *
+   * @-webkit-keyframes my_fade_animation {
+   *   from { opacity:1; }
+   *   to { opacity:0; }
+   * }
+   * ```
+   *
+   * Feel free also mix transitions and keyframes together as well as any other CSS classes on the same element.
+   *
+   * ### CSS Class-based Animations
+   *
+   * Class-based animations (animations that are triggered via `ngClass`, `ngShow`, `ngHide` and some other directives) have a slightly different
+   * naming convention. Class-based animations are basic enough that a standard transition or keyframe can be referenced on the class being added
+   * and removed.
+   *
+   * For example if we wanted to do a CSS animation for `ngHide` then we place an animation on the `.ng-hide` CSS class:
+   *
+   * ```html
+   * 

+   *   Show and hide me
    * 

+   * 
    *
-   * @param {boolean=} flag Enable or disable SVG support in the sanitizer.
-   * @returns {boolean|$sanitizeProvider} Returns the currently configured value if called
-   *    without an argument or self for chaining otherwise.
-   */
-  this.enableSvg = function(enableSvg) {
-    if (isDefined(enableSvg)) {
-      svgEnabled = enableSvg;
-      return this;
-    } else {
-      return svgEnabled;
-    }
-  };
-
-
-  /**
-   * @ngdoc method
-   * @name $sanitizeProvider#addValidElements
-   * @kind function
+   * 
+   * ```
    *
-   * @description
-   * Extends the built-in lists of valid HTML/SVG elements, i.e. elements that are considered safe
-   * and are not stripped off during sanitization. You can extend the following lists of elements:
+   * All that is going on here with ngShow/ngHide behind the scenes is the `.ng-hide` class is added/removed (when the hidden state is valid). Since
+   * ngShow and ngHide are animation aware then we can match up a transition and ngAnimate handles the rest.
+   *
+   * In addition the addition and removal of the CSS class, ngAnimate also provides two helper methods that we can use to further decorate the animation
+   * with CSS styles.
+   *
+   * ```html
+   * 

+   *   Highlight this box
+   * 

+   * 
+   *
+   * 
+   * ```
    *
-   * - `htmlElements`: A list of elements (tag names) to extend the current list of safe HTML
-   *   elements. HTML elements considered safe will not be removed during sanitization. All other
-   *   elements will be stripped off.
+   * We can also make use of CSS keyframes by placing them within the CSS classes.
    *
-   * - `htmlVoidElements`: This is similar to `htmlElements`, but marks the elements as
-   *   "void elements" (similar to HTML
-   *   [void elements](https://rawgit.com/w3c/html/html5.1-2/single-page.html#void-elements)). These
-   *   elements have no end tag and cannot have content.
    *
-   * - `svgElements`: This is similar to `htmlElements`, but for SVG elements. This list is only
-   *   taken into account if SVG is {@link ngSanitize.$sanitizeProvider#enableSvg enabled} for
-   *   `$sanitize`.
+   * ### CSS Staggering Animations
+   * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a
+   * curtain-like effect. The ngAnimate module (versions >=1.2) supports staggering animations and the stagger effect can be
+   * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for
+   * the animation. The style property expected within the stagger class can either be a **transition-delay** or an
+   * **animation-delay** property (or both if your animation contains both transitions and keyframe animations).
    *
-   * 

-   *   This method must be called during the {@link angular.Module#config config} phase. Once the
-   *   `$sanitize` service has been instantiated, this method has no effect.
+   * ```css
+   * .my-animation.ng-enter {
+   *   /* standard transition code */
+   *   transition: 1s linear all;
+   *   opacity:0;
+   * }
+   * .my-animation.ng-enter-stagger {
+   *   /* this will have a 100ms delay between each successive leave animation */
+   *   transition-delay: 0.1s;
+   *
+   *   /* As of 1.4.4, this must always be set: it signals ngAnimate
+   *     to not accidentally inherit a delay property from another CSS class */
+   *   transition-duration: 0s;
+   *
+   *   /* if you are using animations instead of transitions you should configure as follows:
+   *     animation-delay: 0.1s;
+   *     animation-duration: 0s; */
+   * }
+   * .my-animation.ng-enter.ng-enter-active {
+   *   /* standard transition styles */
+   *   opacity:1;
+   * }
+   * ```
+   *
+   * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations
+   * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this
+   * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation
+   * will also be reset if one or more animation frames have passed since the multiple calls to `$animate` were fired.
+   *
+   * The following code will issue the **ng-leave-stagger** event on the element provided:
+   *
+   * ```js
+   * var kids = parent.children();
+   *
+   * $animate.leave(kids[0]); //stagger index=0
+   * $animate.leave(kids[1]); //stagger index=1
+   * $animate.leave(kids[2]); //stagger index=2
+   * $animate.leave(kids[3]); //stagger index=3
+   * $animate.leave(kids[4]); //stagger index=4
+   *
+   * window.requestAnimationFrame(function() {
+   *   //stagger has reset itself
+   *   $animate.leave(kids[5]); //stagger index=0
+   *   $animate.leave(kids[6]); //stagger index=1
+   *
+   *   $scope.$digest();
+   * });
+   * ```
+   *
+   * Stagger animations are currently only supported within CSS-defined animations.
+   *
+   * ### The `ng-animate` CSS class
+   *
+   * When ngAnimate is animating an element it will apply the `ng-animate` CSS class to the element for the duration of the animation.
+   * This is a temporary CSS class and it will be removed once the animation is over (for both JavaScript and CSS-based animations).
+   *
+   * Therefore, animations can be applied to an element using this temporary class directly via CSS.
+   *
+   * ```css
+   * .zipper.ng-animate {
+   *   transition:0.5s linear all;
+   * }
+   * .zipper.ng-enter {
+   *   opacity:0;
+   * }
+   * .zipper.ng-enter.ng-enter-active {
+   *   opacity:1;
+   * }
+   * .zipper.ng-leave {
+   *   opacity:1;
+   * }
+   * .zipper.ng-leave.ng-leave-active {
+   *   opacity:0;
+   * }
+   * ```
+   *
+   * (Note that the `ng-animate` CSS class is reserved and it cannot be applied on an element directly since ngAnimate will always remove
+   * the CSS class once an animation has completed.)
+   *
+   *
+   * ### The `ng-[event]-prepare` class
+   *
+   * This is a special class that can be used to prevent unwanted flickering / flash of content before
+   * the actual animation starts. The class is added as soon as an animation is initialized, but removed
+   * before the actual animation starts (after waiting for a $digest).
+   * It is also only added for *structural* animations (`enter`, `move`, and `leave`).
+   *
+   * In practice, flickering can appear when nesting elements with structural animations such as `ngIf`
+   * into elements that have class-based animations such as `ngClass`.
+   *
+   * ```html
+   * 

+   *   

+   *     

+   *   

    * 

+   * ```
    *
-   * 

-   *   Keep in mind that extending the built-in lists of elements may expose your app to XSS or
-   *   other vulnerabilities. Be very mindful of the elements you add.
+   * It is possible that during the `enter` animation, the `.message` div will be briefly visible before it starts animating.
+   * In that case, you can add styles to the CSS that make sure the element stays hidden before the animation starts:
+   *
+   * ```css
+   * .message.ng-enter-prepare {
+   *   opacity: 0;
+   * }
+   * ```
+   *
+   * ### Animating between value changes
+   *
+   * Sometimes you need to animate between different expression states, whose values
+   * don't necessary need to be known or referenced in CSS styles.
+   * Unless possible with another {@link ngAnimate#directive-support "animation aware" directive},
+   * that specific use case can always be covered with {@link ngAnimate.directive:ngAnimateSwap} as
+   * can be seen in {@link ngAnimate.directive:ngAnimateSwap#examples this example}.
+   *
+   * Note that {@link ngAnimate.directive:ngAnimateSwap} is a *structural directive*, which means it
+   * creates a new instance of the element (including any other/child directives it may have) and
+   * links it to a new scope every time *swap* happens. In some cases this might not be desirable
+   * (e.g. for performance reasons, or when you wish to retain internal state on the original
+   * element instance).
+   *
+   * ## JavaScript-based Animations
+   *
+   * ngAnimate also allows for animations to be consumed by JavaScript code. The approach is similar to CSS-based animations (where there is a shared
+   * CSS class that is referenced in our HTML code) but in addition we need to register the JavaScript animation on the module. By making use of the
+   * `module.animation()` module function we can register the animation.
+   *
+   * Let's see an example of a enter/leave animation using `ngRepeat`:
+   *
+   * ```html
+   * 

+   *   {{ item }}
    * 

+   * ```
    *
-   * @param {Array|Object} elements - A list of valid HTML elements or an object with one or
-   *   more of the following properties:
-   *   - **htmlElements** - `{Array}` - A list of elements to extend the current list of
-   *     HTML elements.
-   *   - **htmlVoidElements** - `{Array}` - A list of elements to extend the current list of
-   *     void HTML elements; i.e. elements that do not have an end tag.
-   *   - **svgElements** - `{Array}` - A list of elements to extend the current list of SVG
-   *     elements. The list of SVG elements is only taken into account if SVG is
-   *     {@link ngSanitize.$sanitizeProvider#enableSvg enabled} for `$sanitize`.
+   * See the **slide** CSS class? Let's use that class to define an animation that we'll structure in our module code by using `module.animation`:
    *
-   * Passing an array (`[...]`) is equivalent to passing `{htmlElements: [...]}`.
+   * ```js
+   * myModule.animation('.slide', [function() {
+   *   return {
+   *     // make note that other events (like addClass/removeClass)
+   *     // have different function input parameters
+   *     enter: function(element, doneFn) {
+   *       jQuery(element).fadeIn(1000, doneFn);
    *
-   * @return {$sanitizeProvider} Returns self for chaining.
-   */
-  this.addValidElements = function(elements) {
-    if (!hasBeenInstantiated) {
-      if (isArray(elements)) {
-        elements = {htmlElements: elements};
-      }
-
-      addElementsTo(svgElements, elements.svgElements);
-      addElementsTo(voidElements, elements.htmlVoidElements);
-      addElementsTo(validElements, elements.htmlVoidElements);
-      addElementsTo(validElements, elements.htmlElements);
-    }
-
-    return this;
-  };

+   * our animations inside of the same registered animation, however, the function input arguments are a bit different:
+   *
+   * ```html
+   * 

+   *   this box is moody
    * 

+   * 
+   *

-   * 

-   *   Keep in mind that extending the built-in list of attributes may expose your app to XSS or

+   * ## CSS + JS Animations Together
+   *
+   * AngularJS 1.4 and higher has taken steps to make the amalgamation of CSS and JS animations more flexible. However, unlike earlier versions of AngularJS,
+   * defining CSS and JS animations to work off of the same CSS class will not work anymore. Therefore the example below will only result in **JS animations taking
+   * charge of the animation**:
+   *
+   * ```html
+   * 

+   *   Slide in and out
+   * 

+   * ```
+   *
+   * ```js
+   * myModule.animation('.slide', [function() {
+   *   return {
+   *     enter: function(element, doneFn) {
+   *       jQuery(element).slideIn(1000, doneFn);
+   *     }
+   *   }
+   * }]);
+   * ```
+   *
+   * ```css
+   * .slide.ng-enter {
+   *   transition:0.5s linear all;
+   *   transform:translateY(-100px);
+   * }
+   * .slide.ng-enter.ng-enter-active {
+   *   transform:translateY(0);
+   * }
+   * ```
+   *
+   * Does this mean that CSS and JS animations cannot be used together? Do JS-based animations always have higher priority? We can make up for the
+   * lack of CSS animations by using the `$animateCss` service to trigger our own tweaked-out, CSS-based animations directly from
+   * our own JS-based animation code:
+   *
+   * ```js
+   * myModule.animation('.slide', ['$animateCss', function($animateCss) {
+   *   return {
+   *     enter: function(element) {
+  *        // this will trigger `.slide.ng-enter` and `.slide.ng-enter-active`.
+   *       return $animateCss(element, {
+   *         event: 'enter',
+   *         structural: true
+   *       });
+   *     }
+   *   }
+   * }]);
+   * ```
+   *
+   * The nice thing here is that we can save bandwidth by sticking to our CSS-based animation code and we don't need to rely on a 3rd-party animation framework.
+   *
+   * The `$animateCss` service is very powerful since we can feed in all kinds of extra properties that will be evaluated and fed into a CSS transition or
+   * keyframe animation. For example if we wanted to animate the height of an element while adding and removing classes then we can do so by providing that
+   * data into `$animateCss` directly:
+   *
+   * ```js
+   * myModule.animation('.slide', ['$animateCss', function($animateCss) {
+   *   return {
+   *     enter: function(element) {
+   *       return $animateCss(element, {
+   *         event: 'enter',
+   *         structural: true,
+   *         addClass: 'maroon-setting',
+   *         from: { height:0 },
+   *         to: { height: 200 }
+   *       });
+   *     }
+   *   }
+   * }]);
+   * ```
+   *
+   * Now we can fill in the rest via our transition CSS code:
+   *
+   * ```css
+   * /* the transition tells ngAnimate to make the animation happen */
+   * .slide.ng-enter { transition:0.5s linear all; }
+   *
+   * /* this extra CSS class will be absorbed into the transition
+   * since the $animateCss code is adding the class */
+   * .maroon-setting { background:red; }
+   * ```
+   *
+   * And `$animateCss` will figure out the rest. Just make sure to have the `done()` callback fire the `doneFn` function to signal when the animation is over.
+   *
+   * To learn more about what's possible be sure to visit the {@link ngAnimate.$animateCss $animateCss service}.
+   *
+   * ## Animation Anchoring (via `ng-animate-ref`)
+   *
+   * ngAnimate in AngularJS 1.4 comes packed with the ability to cross-animate elements between
+   * structural areas of an application (like views) by pairing up elements using an attribute
+   * called `ng-animate-ref`.
+   *
+   * Let's say for example we have two views that are managed by `ng-view` and we want to show
+   * that there is a relationship between two components situated in within these views. By using the
+   * `ng-animate-ref` attribute we can identify that the two components are paired together and we
+   * can then attach an animation, which is triggered when the view changes.
+   *
+   * Say for example we have the following template code:
+   *
+   * ```html
+   * 
+   * 

    * 

    *
-   * @param {Array} attrs - A list of valid attributes.
+   * 
+   * 
+   *   
+   * 
+   *
+   * 
+   * 
+   * ```
+   *
+   * Now, when the view changes (once the link is clicked), ngAnimate will examine the
+   * HTML contents to see if there is a match reference between any components in the view
+   * that is leaving and the view that is entering. It will scan both the view which is being
+   * removed (leave) and inserted (enter) to see if there are any paired DOM elements that
+   * contain a matching ref value.
+   *
+   * The two images match since they share the same ref value. ngAnimate will now create a
+   * transport element (which is a clone of the first image element) and it will then attempt
+   * to animate to the position of the second image element in the next view. For the animation to
+   * work a special CSS class called `ng-anchor` will be added to the transported element.
+   *
+   * We can now attach a transition onto the `.banner.ng-anchor` CSS class and then
+   * ngAnimate will handle the entire transition for us as well as the addition and removal of
+   * any changes of CSS classes between the elements:
+   *
+   * ```css
+   * .banner.ng-anchor {
+   *   /* this animation will last for 1 second since there are
+   *          two phases to the animation (an `in` and an `out` phase) */
+   *   transition:0.5s linear all;
+   * }
+   * ```
+   *
+   * We also **must** include animations for the views that are being entered and removed
+   * (otherwise anchoring wouldn't be possible since the new view would be inserted right away).
+   *
+   * ```css
+   * .view-animation.ng-enter, .view-animation.ng-leave {
+   *   transition:0.5s linear all;
+   *   position:fixed;
+   *   left:0;
+   *   top:0;
+   *   width:100%;
+   * }
+   * .view-animation.ng-enter {
+   *   transform:translateX(100%);
+   * }
+   * .view-animation.ng-leave,
+   * .view-animation.ng-enter.ng-enter-active {
+   *   transform:translateX(0%);
+   * }
+   * .view-animation.ng-leave.ng-leave-active {
+   *   transform:translateX(-100%);
+   * }
+   * ```
+   *
+   * Now we can jump back to the anchor animation. When the animation happens, there are two stages that occur:
+   * an `out` and an `in` stage. The `out` stage happens first and that is when the element is animated away
+   * from its origin. Once that animation is over then the `in` stage occurs which animates the
+   * element to its destination. The reason why there are two animations is to give enough time
+   * for the enter animation on the new element to be ready.
+   *
+   * The example above sets up a transition for both the in and out phases, but we can also target the out or
+   * in phases directly via `ng-anchor-out` and `ng-anchor-in`.
+   *
+   * ```css
+   * .banner.ng-anchor-out {
+   *   transition: 0.5s linear all;
+   *
+   *   /* the scale will be applied during the out animation,
+   *          but will be animated away when the in animation runs */
+   *   transform: scale(1.2);
+   * }
+   *
+   * .banner.ng-anchor-in {
+   *   transition: 1s linear all;
+   * }
+   * ```
+   *
+   *
+   *
+   *

+        }
+      
+    
+   *
+   * ### How is the element transported?
+   *
+   * When an anchor animation occurs, ngAnimate will clone the starting element and position it exactly where the starting
+   * element is located on screen via absolute positioning. The cloned element will be placed inside of the root element
+   * of the application (where ng-app was defined) and all of the CSS classes of the starting element will be applied. The
+   * element will then animate into the `out` and `in` animations and will eventually reach the coordinates and match
+   * the dimensions of the destination element. During the entire animation a CSS class of `.ng-animate-shim` will be applied
+   * to both the starting and destination elements in order to hide them from being visible (the CSS styling for the class
+   * is: `visibility:hidden`). Once the anchor reaches its destination then it will be removed and the destination element
+   * will become visible since the shim class will be removed.
+   *
+   * ### How is the morphing handled?
+   *
+   * CSS Anchoring relies on transitions and keyframes and the internal code is intelligent enough to figure out
+   * what CSS classes differ between the starting element and the destination element. These different CSS classes
+   * will be added/removed on the anchor element and a transition will be applied (the transition that is provided
+   * in the anchor class). Long story short, ngAnimate will figure out what classes to add and remove which will
+   * make the transition of the element as smooth and automatic as possible. Be sure to use simple CSS classes that
+   * do not rely on DOM nesting structure so that the anchor element appears the same as the starting element (since
+   * the cloned element is placed inside of root element which is likely close to the body element).
+   *
+   * Note that if the root element is on the `` element then the cloned node will be placed inside of body.
+   *
+   *
+   * ## Using $animate in your directive code
+   *
+   * So far we've explored how to feed in animations into an AngularJS application, but how do we trigger animations within our own directives in our application?
+   * By injecting the `$animate` service into our directive code, we can trigger structural and class-based hooks which can then be consumed by animations. Let's
+   * imagine we have a greeting box that shows and hides itself when the data changes
+   *
+   * ```html
+   * Hi there
+   * ```
+   *
+   * ```js
+   * ngModule.directive('greetingBox', ['$animate', function($animate) {
+   *   return function(scope, element, attrs) {
+   *     attrs.$observe('active', function(value) {
+   *       value ? $animate.addClass(element, 'on') : $animate.removeClass(element, 'on');
+   *     });
+   *   });
+   * }]);
+   * ```
+   *
+   * Now the `on` CSS class is added and removed on the greeting box component. Now if we add a CSS class on top of the greeting box element
+   * in our HTML code then we can trigger a CSS or JS animation to happen.
+   *
+   * ```css
+   * /* normally we would create a CSS class to reference on the element */
+   * greeting-box.on { transition:0.5s linear all; background:green; color:white; }
+   * ```
+   *
+   * The `$animate` service contains a variety of other methods like `enter`, `leave`, `animate` and `setClass`. To learn more about what's
+   * possible be sure to visit the {@link ng.$animate $animate service API page}.
+   *
+   *
+   * ## Callbacks and Promises
+   *
+   * When `$animate` is called it returns a promise that can be used to capture when the animation has ended. Therefore if we were to trigger
+   * an animation (within our directive code) then we can continue performing directive and scope related activities after the animation has
+   * ended by chaining onto the returned promise that animation method returns.
+   *
+   * ```js
+   * // somewhere within the depths of the directive
+   * $animate.enter(element, parent).then(function() {
+   *   //the animation has completed
+   * });
+   * ```
+   *
+   * (Note that earlier versions of AngularJS prior to v1.4 required the promise code to be wrapped using `$scope.$apply(...)`. This is not the case
+   * anymore.)
+   *
+   * In addition to the animation promise, we can also make use of animation-related callbacks within our directives and controller code by registering
+   * an event listener using the `$animate` service. Let's say for example that an animation was triggered on our view
+   * routing controller to hook into that:
+   *
+   * ```js
+   * ngModule.controller('HomePageController', ['$animate', function($animate) {
+   *   $animate.on('enter', ngViewElement, function(element) {
+   *     // the animation for this route has completed
+   *   }]);
+   * }])
+   * ```
    *
-   * @returns {$sanitizeProvider} Returns self for chaining.
+   * (Note that you will need to trigger a digest within the callback to get AngularJS to notice any scope-related changes.)

- *
- * @description
- * Finds links in text input and turns them into html links. Supports `http/https/ftp/sftp/mailto` and
- * plain email address links.
- *
- * Requires the {@link ngSanitize `ngSanitize`} module to be installed.
- *
- * @param {string} text Input text.
- * @param {string} [target] Window (`_blank|_self|_parent|_top`) or named frame to open links in.
- * @param {object|function(url)} [attributes] Add custom attributes to the link element.
- *
- *    Can be one of:
- *
- *    - `object`: A map of attributes
- *    - `function`: Takes the url as a parameter and returns a map of attributes
- *
- *    If the map of attributes contains a value for `target`, it overrides the value of
- *    the target parameter.
- *
- *
- * @returns {string} Html-linkified and {@link $sanitize sanitized} text.

- *
- * The above creates an instance of minErr in the example namespace. The

- * If fewer arguments are specified than necessary for interpolation, the extra
- * interpolation markers will be preserved in the final string.

- * are applied with respect to how minErr instances are created and called.

- * * If a destination is provided, all of its elements (for arrays) or properties (for objects)

- * * If `source` is identical to `destination` an exception will be thrown.
- *
- * 

- * 

- *   Only enumerable properties are taken into account. Non-enumerable properties (both on `source`
- *   and on `destination`) will be ignored.
- * 

- *
- * @param {*} source The source that will be used to make a copy.
- *                   Can be any type, including primitives, `null`, and `undefined`.
- * @param {(Object|Array)=} destination Destination into which the source is copied. If

-/**
- * @ngdoc directive
- * @name ngApp
- * @module ng
- *
- * @element ANY
- * @param {angular.Module} ngApp an optional application
- *   {@link angular.module module} name to load.
- * @param {boolean=} ngStrictDi if this attribute is present on the app element, the injector will be
- *   created in "strict-di" mode. This means that the application will fail to invoke functions which
- *   do not use explicit function annotation (and are thus unsuitable for minification), as described
- *   in {@link guide/di the Dependency Injection guide}, and useful debugging info will assist in
- *   tracking down the root of these bugs.
- *
- * @description
- *
- * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
- * designates the **root element** of the application and is typically placed near the root element
- * of the page - e.g. on the `` or `` tags.
- *
- * There are a few things to keep in mind when using `ngApp`:
- * - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
- *   found in the document will be used to define the root element to auto-bootstrap as an
- *   application. To run multiple applications in an HTML document you must manually bootstrap them using
- *   {@link angular.bootstrap} instead.
- * - AngularJS applications cannot be nested within each other.
- * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.
- *   This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and
- *   {@link ngRoute.ngView `ngView`}.
- *   Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
- *   causing animations to stop working and making the injector inaccessible from outside the app.
- *
- * You can specify an **AngularJS module** to be used as the root module for the application.  This
- * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
- * should contain the application code needed or have dependencies on other modules that will
- * contain the code. See {@link angular.module} for more information.
- *
- * In the example below if the `ngApp` directive were not placed on the `html` element then the
- * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
- * would not be resolved to `3`.
- *
- * @example
- *
- * ### Simple Usage
- *
- * `ngApp` is the easiest, and most common way to bootstrap an application.
- *
- 
-   
-   

-     I can add: {{a}} + {{b}} =  {{ a+b }}
-   

-   
-   
-   angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) {
-     $scope.a = 1;
-     $scope.b = 2;
-   });
-   
- 
- *
- * @example
- *
- * ### With `ngStrictDi`
- *
- * Using `ngStrictDi`, you would see something like this:
- *
- 
-   
-   

-       

-           I can add: {{a}} + {{b}} =  {{ a+b }}
-
-           
This renders because the controller does not fail to
-              instantiate, by using explicit annotation style (see
-              script.js for details)
-           

-       

-
-       

-           Name: 

-           Hello, {{name}}!
+    return jq.name_ = name;
+  };
 
-           
This renders because the controller does not fail to
-              instantiate, by using explicit annotation style
-              (see script.js for details)
-           

-       

+  function concat(array1, array2, index) {
+    return array1.concat(slice.call(array2, index));
+  }
 
-       

-           I can add: {{a}} + {{b}} =  {{ a+b }}
+  function sliceArgs(args, startIndex) {
+    return slice.call(args, startIndex || 0);
+  }
 
-           
The controller could not be instantiated, due to relying
-              on automatic function annotations (which are disabled in
-              strict mode). As such, the content of this section is not
-              interpolated, and there should be an error in your web console.

-   
-   
-   angular.module('ngAppStrictDemo', [])
-     // BadController will fail to instantiate, due to relying on automatic function annotation,
-     // rather than an explicit annotation
-     .controller('BadController', function($scope) {
-       $scope.a = 1;
-       $scope.b = 2;
-     })
-     // Unlike BadController, GoodController1 and GoodController2 will not fail to be instantiated,
-     // due to using explicit annotations using the array style and $inject property, respectively.
-     .controller('GoodController1', ['$scope', function($scope) {
-       $scope.a = 1;
-       $scope.b = 2;

+  /**
+   * @ngdoc directive
+   * @name ngApp
+   * @module ng
+   *
+   * @element ANY
+   * @param {angular.Module} ngApp an optional application
+   *   {@link angular.module module} name to load.
+   * @param {boolean=} ngStrictDi if this attribute is present on the app element, the injector will be
+   *   created in "strict-di" mode. This means that the application will fail to invoke functions which
+   *   do not use explicit function annotation (and are thus unsuitable for minification), as described
+   *   in {@link guide/di the Dependency Injection guide}, and useful debugging info will assist in
+   *   tracking down the root of these bugs.
+   *
+   * @description
+   *
+   * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
+   * designates the **root element** of the application and is typically placed near the root element
+   * of the page - e.g. on the `` or `` tags.
+   *
+   * There are a few things to keep in mind when using `ngApp`:
+   * - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
+   *   found in the document will be used to define the root element to auto-bootstrap as an
+   *   application. To run multiple applications in an HTML document you must manually bootstrap them using
+   *   {@link angular.bootstrap} instead.
+   * - AngularJS applications cannot be nested within each other.
+   * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.
+   *   This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and
+   *   {@link ngRoute.ngView `ngView`}.
+   *   Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
+   *   causing animations to stop working and making the injector inaccessible from outside the app.
+   *
+   * You can specify an **AngularJS module** to be used as the root module for the application.  This
+   * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
+   * should contain the application code needed or have dependencies on other modules that will
+   * contain the code. See {@link angular.module} for more information.
+   *
+   * In the example below if the `ngApp` directive were not placed on the `html` element then the
+   * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
+   * would not be resolved to `3`.
+   *
+   * @example
+   *
+   * ### Simple Usage
+   *
+   * `ngApp` is the easiest, and most common way to bootstrap an application.
+   *
+   
+     
+     

+       I can add: {{a}} + {{b}} =  {{ a+b }}
+     

+     
+     
+     angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) {
+       $scope.a = 1;
+       $scope.b = 2;
+     });
+     
+   
+   *
+   * @example
+   *
+   * ### With `ngStrictDi`
+   *
+   * Using `ngStrictDi`, you would see something like this:
+   *
+   
+     
+     

+         

+             I can add: {{a}} + {{b}} =  {{ a+b }}
+  
+             
This renders because the controller does not fail to
+                instantiate, by using explicit annotation style (see
+                script.js for details)
+             

+         

+  
+         

+             Name: 

+             Hello, {{name}}!
+  
+             
This renders because the controller does not fail to
+                instantiate, by using explicit annotation style
+                (see script.js for details)
+             

+         

+  
+         

+             I can add: {{a}} + {{b}} =  {{ a+b }}
+  
+             
The controller could not be instantiated, due to relying
+                on automatic function annotations (which are disabled in
+                strict mode). As such, the content of this section is not
+                interpolated, and there should be an error in your web console.

+       *
+       * The `angular.module` is a global place for creating, registering and retrieving AngularJS
+       * modules.
+       * All modules (AngularJS core or 3rd party) that should be available to an application must be
+       * registered using this mechanism.
+       *
+       * Passing one argument retrieves an existing {@link angular.Module},
+       * whereas passing more than one argument creates a new {@link angular.Module}
+       *
+       *
+       * # Module
+       *
+       * A module is a collection of services, directives, controllers, filters, and configuration information.
+       * `angular.module` is used to configure the {@link auto.$injector $injector}.
+       *
+       * ```js
+       * // Create a new module
+       * var myModule = angular.module('myModule', []);
+       *
+       * // register a new service
+       * myModule.value('appName', 'MyCoolApp');
+       *
+       * // configure existing services inside initialization blocks.
+       * myModule.config(['$locationProvider', function($locationProvider) {
+       *   // Configure existing providers
+       *   $locationProvider.hashPrefix('!');
+       * }]);
+       * ```
+       *
+       * Then you can create an injector and load your modules like this:
+       *
+       * ```js
+       * var injector = angular.injector(['ng', 'myModule'])
+       * ```
+       *
+       * However it's more likely that you'll just use
+       * {@link ng.directive:ngApp ngApp} or
+       * {@link angular.bootstrap} to simplify this process for you.
+       *
+       * @param {!string} name The name of the module to create or retrieve.
+       * @param {!Array.=} requires If specified then new module is being created. If
+       *        unspecified then the module is being retrieved for further configuration.
+       * @param {Function=} configFn Optional configuration function for the module. Same as
+       *        {@link angular.Module#config Module#config()}.
+       * @returns {angular.Module} new module with the {@link angular.Module} api.

-/**
- * @ngdoc function
- * @name angular.element
- * @module ng
- * @kind function
- *
- * @description
- * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
- *
- * If jQuery is available, `angular.element` is an alias for the
- * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
- * delegates to AngularJS's built-in subset of jQuery, called "jQuery lite" or **jqLite**.
- *
- * jqLite is a tiny, API-compatible subset of jQuery that allows
- * AngularJS to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most
- * commonly needed functionality with the goal of having a very small footprint.
- *
- * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the
- * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a
- * specific version of jQuery if multiple versions exist on the page.
- *
- * 
**Note:** All element references in AngularJS are always wrapped with jQuery or
- * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.

- *
- * 
**Note:** Keep in mind that this function will not find elements
- * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`
- * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.

- *
- * ## AngularJS's jqLite
- * jqLite provides only the following jQuery methods:
- *
- * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument
- * - [`after()`](http://api.jquery.com/after/)
- * - [`append()`](http://api.jquery.com/append/) - Contrary to jQuery, this doesn't clone elements
- *   so will not work correctly when invoked on a jqLite object containing more than one DOM node
- * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
- * - [`bind()`](http://api.jquery.com/bind/) (_deprecated_, use [`on()`](http://api.jquery.com/on/)) - Does not support namespaces, selectors or eventData
- * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
- * - [`clone()`](http://api.jquery.com/clone/)
- * - [`contents()`](http://api.jquery.com/contents/)
- * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.
- *   As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.
- * - [`data()`](http://api.jquery.com/data/)
- * - [`detach()`](http://api.jquery.com/detach/)
- * - [`empty()`](http://api.jquery.com/empty/)
- * - [`eq()`](http://api.jquery.com/eq/)
- * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
- * - [`hasClass()`](http://api.jquery.com/hasClass/)
- * - [`html()`](http://api.jquery.com/html/)
- * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
- * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
- * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter
- * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
- * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
- * - [`prepend()`](http://api.jquery.com/prepend/)
- * - [`prop()`](http://api.jquery.com/prop/)
- * - [`ready()`](http://api.jquery.com/ready/) (_deprecated_, use `angular.element(callback)` instead of `angular.element(document).ready(callback)`)
- * - [`remove()`](http://api.jquery.com/remove/)
- * - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes
- * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument
- * - [`removeData()`](http://api.jquery.com/removeData/)
- * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
- * - [`text()`](http://api.jquery.com/text/)
- * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument
- * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers
- * - [`unbind()`](http://api.jquery.com/unbind/) (_deprecated_, use [`off()`](http://api.jquery.com/off/)) - Does not support namespaces or event object as parameter
- * - [`val()`](http://api.jquery.com/val/)
- * - [`wrap()`](http://api.jquery.com/wrap/)
- *
- * ## jQuery/jqLite Extras
- * AngularJS also provides the following additional methods and events to both jQuery and jqLite:
- *
- * ### Events
- * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
- *    on all DOM nodes being removed.  This can be used to clean up any 3rd party bindings to the DOM
- *    element before it is removed.
- *
- * ### Methods
- * - `controller(name)` - retrieves the controller of the current element or its parent. By default
- *   retrieves controller associated with the `ngController` directive. If `name` is provided as
- *   camelCase directive name, then the controller for this directive will be retrieved (e.g.
- *   `'ngModel'`).
- * - `injector()` - retrieves the injector of the current element or its parent.
- * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
- *   element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to
- *   be enabled.
- * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
- *   current element. This getter should be used only on elements that contain a directive which starts a new isolate
- *   scope. Calling `scope()` on this element always returns the original non-isolate scope.
- *   Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.
- * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
- *   parent element is reached.
- *
- * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See
- * https://github.com/angular/angular.js/issues/14251 for more information.
- *
- * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
- * @returns {Object} jQuery object.

- * @ngdoc function
- * @module ng
- * @name angular.injector
- * @kind function
- *
- * @description
- * Creates an injector object that can be used for retrieving services as well as for
- * dependency injection (see {@link guide/di dependency injection}).
- *
- * @param {Array.} modules A list of module functions or their aliases. See
- *     {@link angular.module}. The `ng` module must be explicitly added.
- * @param {boolean=} [strictDi=false] Whether the injector should be in strict mode, which
- *     disallows argument name annotation inference.
- * @returns {injector} Injector object. See {@link auto.$injector $injector}.
- *
- * @example
- * Typical usage
- * ```js
- *   // create an injector
- *   var $injector = angular.injector(['ng']);
- *
- *   // use the injector to kick off your application
- *   // use the type inference to auto inject arguments, or use implicit injection
- *   $injector.invoke(function($rootScope, $compile, $document) {
- *     $compile($document)($rootScope);
- *     $rootScope.$digest();
- *   });
- * ```
- *
- * Sometimes you want to get access to the injector of a currently running AngularJS app
- * from outside AngularJS. Perhaps, you want to inject and compile some markup after the
- * application has been bootstrapped. You can do this using the extra `injector()` added
- * to JQuery/jqLite elements. See {@link angular.element}.
- *
- * *This is fairly rare but could be the case if a third party library is injecting the
- * markup.*
- *
- * In the following example a new block of HTML containing a `ng-controller`
- * directive is added to the end of the document body by JQuery. We then compile and link
- * it into the current AngularJS scope.
- *
- * ```js
- * var $div = $('
{{content.label}}
');
- * $(document.body).append($div);
- *
- * angular.element(document).injector().invoke(function($compile) {
- *   var scope = angular.element($div).scope();
- *   $compile($div)(scope);
- * });
- * ```

-/**
- * @ngdoc service
- * @name $injector
- *
- * @description
- *
- * `$injector` is used to retrieve object instances as defined by
- * {@link auto.$provide provider}, instantiate types, invoke methods,
- * and load modules.
- *
- * The following always holds true:
- *
- * ```js
- *   var $injector = angular.injector();
- *   expect($injector.get('$injector')).toBe($injector);
- *   expect($injector.invoke(function($injector) {
- *     return $injector;
- *   })).toBe($injector);
- * ```
- *
- * ## Injection Function Annotation
- *
- * JavaScript does not have annotations, and annotations are needed for dependency injection. The
- * following are all valid ways of annotating function with injection arguments and are equivalent.
- *
- * ```js
- *   // inferred (only works if code not minified/obfuscated)
- *   $injector.invoke(function(serviceA){});
- *
- *   // annotated
- *   function explicit(serviceA) {};
- *   explicit.$inject = ['serviceA'];
- *   $injector.invoke(explicit);
- *
- *   // inline
- *   $injector.invoke(['serviceA', function(serviceA){}]);
- * ```
- *
- * ### Inference
- *
- * In JavaScript calling `toString()` on a function returns the function definition. The definition
- * can then be parsed and the function arguments can be extracted. This method of discovering
- * annotations is disallowed when the injector is in strict mode.
- * *NOTE:* This does not work with minification, and obfuscation tools since these tools change the
- * argument names.
- *
- * ### `$inject` Annotation
- * By adding an `$inject` property onto a function the injection parameters can be specified.
- *
- * ### Inline
- * As an array of injection names, where the last item in the array is the function to call.

-/**
- * @ngdoc method
- * @name $injector#annotate
- *
- * @description
- * Returns an array of service names which the function is requesting for injection. This API is
- * used by the injector to determine which services need to be injected into the function when the
- * function is invoked. There are three ways in which the function can be annotated with the needed
- * dependencies.
- *
- * #### Argument names
- *
- * The simplest form is to extract the dependencies from the arguments of the function. This is done
- * by converting the function into a string using `toString()` method and extracting the argument
- * names.
- * ```js
- *   // Given
- *   function MyController($scope, $route) {
- *     // ...
- *   }
- *
- *   // Then
- *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
- * ```
- *
- * You can disallow this method by using strict injection mode.
- *
- * This method does not work with code minification / obfuscation. For this reason the following
- * annotation strategies are supported.
- *
- * #### The `$inject` property
- *
- * If a function has an `$inject` property and its value is an array of strings, then the strings
- * represent names of services to be injected into the function.
- * ```js
- *   // Given
- *   var MyController = function(obfuscatedScope, obfuscatedRoute) {
- *     // ...
- *   }
- *   // Define function dependencies
- *   MyController['$inject'] = ['$scope', '$route'];
- *
- *   // Then
- *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
- * ```
- *
- * #### The array notation
- *
- * It is often desirable to inline Injected functions and that's when setting the `$inject` property
- * is very inconvenient. In these situations using the array notation to specify the dependencies in
- * a way that survives minification is a better choice:
- *
- * ```js
- *   // We wish to write this (not minification / obfuscation safe)
- *   injector.invoke(function($compile, $rootScope) {
- *     // ...
- *   });
- *
- *   // We are forced to write break inlining
- *   var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
- *     // ...
- *   };
- *   tmpFn.$inject = ['$compile', '$rootScope'];
- *   injector.invoke(tmpFn);
- *
- *   // To better support inline function the inline annotation is supported
- *   injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
- *     // ...
- *   }]);
- *
- *   // Therefore
- *   expect(injector.annotate(
- *      ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
- *    ).toEqual(['$compile', '$rootScope']);
- * ```
- *
- * @param {Function|Array.} fn Function for which dependent service names need to
- * be retrieved as described above.
- *
- * @param {boolean=} [strictDi=false] Disallow argument name annotation inference.
- *
- * @returns {Array.} The names of the services which the function requires.

-/**
- * @ngdoc method
- * @name $injector#loadNewModules
- *
- * @description
- *
- * **This is a dangerous API, which you use at your own risk!**
- *
- * Add the specified modules to the current injector.
- *
- * This method will add each of the injectables to the injector and execute all of the config and run
- * blocks for each module passed to the method.
- *
- * If a module has already been loaded into the injector then it will not be loaded again.
- *
- * * The application developer is responsible for loading the code containing the modules; and for
- * ensuring that lazy scripts are not downloaded and executed more often that desired.
- * * Previously compiled HTML will not be affected by newly loaded directives, filters and components.
- * * Modules cannot be unloaded.
- *
- * You can use {@link $injector#modules `$injector.modules`} to check whether a module has been loaded
- * into the injector, which may indicate whether the script has been executed already.
- *
- * @example
- * Here is an example of loading a bundle of modules, with a utility method called `getScript`:
- *
- * ```javascript
- * app.factory('loadModule', function($injector) {
- *   return function loadModule(moduleName, bundleUrl) {
- *     return getScript(bundleUrl).then(function() { $injector.loadNewModules([moduleName]); });
- *   };
- * })
- * ```
- *
- * @param {Array=} mods an array of modules to load into the application.
- *     Each item in the array should be the name of a predefined module or a (DI annotated)
- *     function that will be invoked by the injector as a `config` block.
- *     See: {@link angular.module modules}

- * @description
- *
- * The {@link auto.$provide $provide} service has a number of methods for registering components
- * with the {@link auto.$injector $injector}. Many of these functions are also exposed on
- * {@link angular.Module}.
- *
- * An AngularJS **service** is a singleton object created by a **service factory**.  These **service
- * factories** are functions which, in turn, are created by a **service provider**.
- * The **service providers** are constructor functions. When instantiated they must contain a
- * property called `$get`, which holds the **service factory** function.
- *
- * When you request a service, the {@link auto.$injector $injector} is responsible for finding the
- * correct **service provider**, instantiating it and then calling its `$get` **service factory**
- * function to get the instance of the **service**.
- *
- * Often services have no configuration options and there is no need to add methods to the service
- * provider.  The provider will be no more than a constructor function with a `$get` property. For
- * these cases the {@link auto.$provide $provide} service has additional helper methods to register
- * services without specifying a provider.
- *
- * * {@link auto.$provide#provider provider(name, provider)} - registers a **service provider** with the
- *     {@link auto.$injector $injector}
- * * {@link auto.$provide#constant constant(name, obj)} - registers a value/object that can be accessed by
- *     providers and services.
- * * {@link auto.$provide#value value(name, obj)} - registers a value/object that can only be accessed by
- *     services, not providers.
- * * {@link auto.$provide#factory factory(name, fn)} - registers a service **factory function**
- *     that will be wrapped in a **service provider** object, whose `$get` property will contain the
- *     given factory function.
- * * {@link auto.$provide#service service(name, Fn)} - registers a **constructor function**
- *     that will be wrapped in a **service provider** object, whose `$get` property will instantiate
- *      a new object using the given constructor function.
- * * {@link auto.$provide#decorator decorator(name, decorFn)} - registers a **decorator function** that
- *      will be able to modify or replace the implementation of another service.

-/**
- * @ngdoc method
- * @name $provide#provider
- * @description
- *
- * Register a **provider function** with the {@link auto.$injector $injector}. Provider functions
- * are constructor functions, whose instances are responsible for "providing" a factory for a
- * service.
- *
- * Service provider names start with the name of the service they provide followed by `Provider`.
- * For example, the {@link ng.$log $log} service has a provider called
- * {@link ng.$logProvider $logProvider}.
- *
- * Service provider objects can have additional methods which allow configuration of the provider
- * and its service. Importantly, you can configure what kind of service is created by the `$get`
- * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
- * method {@link ng.$logProvider#debugEnabled debugEnabled}
- * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
- * console or not.
- *
- * It is possible to inject other providers into the provider function,
- * but the injected provider must have been defined before the one that requires it.
- *
- * @param {string} name The name of the instance. NOTE: the provider will be available under `name +
-                        'Provider'` key.
- * @param {(Object|function())} provider If the provider is:
- *
- *   - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
- *     {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
- *   - `Constructor`: a new instance of the provider will be created using
- *     {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.
- *
- * @returns {Object} registered provider instance
-
- * @example
- *
- * The following example shows how to create a simple event tracking service and register it using
- * {@link auto.$provide#provider $provide.provider()}.

- *  // Define the eventTracker provider
- *  function EventTrackerProvider() {

    * @description
-   * When called, it scrolls to the element related to the specified `hash` or (if omitted) to the
-   * current value of {@link ng.$location#hash $location.hash()}, according to the rules specified
-   * in the
-   * [HTML5 spec](http://www.w3.org/html/wg/drafts/html/master/browsers.html#an-indicated-part-of-the-document).
-   *
-   * It also watches the {@link ng.$location#hash $location.hash()} and automatically scrolls to
-   * match any anchor whenever it changes. This can be disabled by calling
-   * {@link ng.$anchorScrollProvider#disableAutoScrolling $anchorScrollProvider.disableAutoScrolling()}.
-   *
-   * Additionally, you can use its {@link ng.$anchorScroll#yOffset yOffset} property to specify a
-   * vertical scroll-offset (either fixed or dynamic).
-   *
-   * @param {string=} hash The hash specifying the element to scroll to. If omitted, the value of
-   *                       {@link ng.$location#hash $location.hash()} will be used.
-   *
-   * @property {(number|function|jqLite)} yOffset
-   * If set, specifies a vertical scroll-offset. This is often useful when there are fixed
-   * positioned elements at the top of the page, such as navbars, headers etc.
-   *
-   * `yOffset` can be specified in various ways:
-   * - **number**: A fixed number of pixels to be used as offset.


-   * - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return
-   *   a number representing the offset (in pixels).


-   * - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from
-   *   the top of the page to the element's bottom will be used as offset.

-   *   **Note**: The element will be taken into account only as long as its `position` is set to
-   *   `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust
-   *   their height and/or positioning according to the viewport's size.
+   * Creates an injector object that can be used for retrieving services as well as for
+   * dependency injection (see {@link guide/di dependency injection}).
    *
-   * 

-   * 

-   * In order for `yOffset` to work properly, scrolling should take place on the document's root and
-   * not some child element.
-   * 

+   * @param {Array.} modules A list of module functions or their aliases. See
+   *     {@link angular.module}. The `ng` module must be explicitly added.
+   * @param {boolean=} [strictDi=false] Whether the injector should be in strict mode, which
+   *     disallows argument name annotation inference.
+   * @returns {injector} Injector object. See {@link auto.$injector $injector}.
    *
    * @example
-     
-       
-         

-           Go to bottom
-            You're at the bottom!
-         

-       
-       
-         angular.module('anchorScrollExample', [])
-           .controller('ScrollController', ['$scope', '$location', '$anchorScroll',

-                 // set the location.hash to the id of

-                 $location.hash('bottom');
-
-                 // call $anchorScroll()
-                 $anchorScroll();
-               };

-           display: block;
-           margin-top: 2000px;
-         }
-       
-     
+   * Typical usage
+   * ```js
+   *   // create an injector
+   *   var $injector = angular.injector(['ng']);
+   *
+   *   // use the injector to kick off your application
+   *   // use the type inference to auto inject arguments, or use implicit injection
+   *   $injector.invoke(function($rootScope, $compile, $document) {
+   *     $compile($document)($rootScope);
+   *     $rootScope.$digest();
+   *   });
+   * ```
    *
-   * 

-   * The example below illustrates the use of a vertical scroll-offset (specified as a fixed value).
-   * See {@link ng.$anchorScroll#yOffset $anchorScroll.yOffset} for more details.
+   * Sometimes you want to get access to the injector of a currently running AngularJS app
+   * from outside AngularJS. Perhaps, you want to inject and compile some markup after the
+   * application has been bootstrapped. You can do this using the extra `injector()` added
+   * to JQuery/jqLite elements. See {@link angular.element}.

+  /**
+   * @ngdoc service
+   * @name $injector
    *
    * @description
-   * Registers a new injectable animation factory function. The factory function produces the
-   * animation object which contains callback functions for each event that is expected to be
-   * animated.
    *
-   *   * `eventFn`: `function(element, ... , doneFunction, options)`
-   *   The element to animate, the `doneFunction` and the options fed into the animation. Depending
-   *   on the type of animation additional arguments will be injected into the animation function. The
-   *   list below explains the function signatures for the different animation methods:
+   * `$injector` is used to retrieve object instances as defined by
+   * {@link auto.$provide provider}, instantiate types, invoke methods,
+   * and load modules.
    *
-   *   - setClass: function(element, addedClasses, removedClasses, doneFunction, options)

-   *   - removeClass: function(element, removedClasses, doneFunction, options)
-   *   - enter, leave, move: function(element, doneFunction, options)
-   *   - animate: function(element, fromStyles, toStyles, doneFunction, options)
+   * The following always holds true:
    *
-   *   Make sure to trigger the `doneFunction` once the animation is fully complete.
+   * ```js
+   *   var $injector = angular.injector();
+   *   expect($injector.get('$injector')).toBe($injector);
+   *   expect($injector.invoke(function($injector) {
+   *     return $injector;
+   *   })).toBe($injector);
+   * ```
+   *
+   * ## Injection Function Annotation
+   *
+   * JavaScript does not have annotations, and annotations are needed for dependency injection. The
+   * following are all valid ways of annotating function with injection arguments and are equivalent.
    *
    * ```js
-   *   return {
-   *     //enter, leave, move signature
-   *     eventFn : function(element, done, options) {
-   *       //code to run the animation
-   *       //once complete, then run done()
-   *       return function endFunction(wasCancelled) {
-   *         //code to cancel the animation
-   *       }
-   *     }
-   *   }
+   *   // inferred (only works if code not minified/obfuscated)
+   *   $injector.invoke(function(serviceA){});
+   *
+   *   // annotated
+   *   function explicit(serviceA) {};
+   *   explicit.$inject = ['serviceA'];
+   *   $injector.invoke(explicit);
+   *
+   *   // inline
+   *   $injector.invoke(['serviceA', function(serviceA){}]);

-   * @param {Function} factory The factory function that will be executed to return the animation
-   *                           object.
+   * ### Inference
+   *
+   * In JavaScript calling `toString()` on a function returns the function definition. The definition
+   * can then be parsed and the function arguments can be extracted. This method of discovering
+   * annotations is disallowed when the injector is in strict mode.
+   * *NOTE:* This does not work with minification, and obfuscation tools since these tools change the
+   * argument names.
+   *
+   * ### `$inject` Annotation
+   * By adding an `$inject` property onto a function the injection parameters can be specified.
+   *
+   * ### Inline
+   * As an array of injection names, where the last item in the array is the function to call.

+   * @description
+   * Returns an array of service names which the function is requesting for injection. This API is
+   * used by the injector to determine which services need to be injected into the function when the
+   * function is invoked. There are three ways in which the function can be annotated with the needed
+   * dependencies.
+   *
+   * #### Argument names
+   *
+   * The simplest form is to extract the dependencies from the arguments of the function. This is done
+   * by converting the function into a string using `toString()` method and extracting the argument
+   * names.
+   * ```js
+   *   // Given
+   *   function MyController($scope, $route) {
+   *     // ...
+   *   }
+   *
+   *   // Then
+   *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
+   * ```
+   *
+   * You can disallow this method by using strict injection mode.
+   *
+   * This method does not work with code minification / obfuscation. For this reason the following
+   * annotation strategies are supported.
+   *
+   * #### The `$inject` property
+   *
+   * If a function has an `$inject` property and its value is an array of strings, then the strings
+   * represent names of services to be injected into the function.
+   * ```js
+   *   // Given
+   *   var MyController = function(obfuscatedScope, obfuscatedRoute) {
+   *     // ...
+   *   }
+   *   // Define function dependencies
+   *   MyController['$inject'] = ['$scope', '$route'];
+   *
+   *   // Then
+   *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
+   * ```
+   *
+   * #### The array notation
+   *
+   * It is often desirable to inline Injected functions and that's when setting the `$inject` property
+   * is very inconvenient. In these situations using the array notation to specify the dependencies in
+   * a way that survives minification is a better choice:
+   *
+   * ```js
+   *   // We wish to write this (not minification / obfuscation safe)
+   *   injector.invoke(function($compile, $rootScope) {
+   *     // ...
+   *   });
+   *
+   *   // We are forced to write break inlining
+   *   var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
+   *     // ...
+   *   };
+   *   tmpFn.$inject = ['$compile', '$rootScope'];
+   *   injector.invoke(tmpFn);
+   *
+   *   // To better support inline function the inline annotation is supported
+   *   injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
+   *     // ...
+   *   }]);
+   *
+   *   // Therefore
+   *   expect(injector.annotate(
+   *      ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
+   *    ).toEqual(['$compile', '$rootScope']);
+   * ```
+   *
+   * @param {Function|Array.} fn Function for which dependent service names need to
+   * be retrieved as described above.
+   *
+   * @param {boolean=} [strictDi=false] Disallow argument name annotation inference.

-   * an animation. Upon bootstrap the classNameFilter value is not set at all and will
-   * therefore enable $animate to attempt to perform an animation on any element that is triggered.
-   * When setting the `classNameFilter` value, animations will only be performed on elements
-   * that successfully match the filter expression. This in turn can boost performance
-   * for low-powered devices as well as applications containing a lot of structural operations.
-   *
-   * **Note:** If present, `classNameFilter` will be checked after
-   * {@link $animateProvider#customFilter customFilter}. If `customFilter` is present and returns
-   * false, `classNameFilter` will not be checked.
-   *
-   * @param {RegExp=} expression The className expression which will be checked against all animations
-   * @return {RegExp} The current CSS className expression value. If null then there is no expression value
+   *
+   * **This is a dangerous API, which you use at your own risk!**

+   * Add the specified modules to the current injector.
+   *
+   * This method will add each of the injectables to the injector and execute all of the config and run
+   * blocks for each module passed to the method.
+   *
+   * If a module has already been loaded into the injector then it will not be loaded again.
+   *
+   * * The application developer is responsible for loading the code containing the modules; and for
+   * ensuring that lazy scripts are not downloaded and executed more often that desired.
+   * * Previously compiled HTML will not be affected by newly loaded directives, filters and components.
+   * * Modules cannot be unloaded.
+   *
+   * You can use {@link $injector#modules `$injector.modules`} to check whether a module has been loaded
+   * into the injector, which may indicate whether the script has been executed already.
+   *
+   * @example
+   * Here is an example of loading a bundle of modules, with a utility method called `getScript`:
+   *
+   * ```javascript
+   * app.factory('loadModule', function($injector) {
+   *   return function loadModule(moduleName, bundleUrl) {
+   *     return getScript(bundleUrl).then(function() { $injector.loadNewModules([moduleName]); });
+   *   };
+   * })
+   * ```
+   *
+   * @param {Array=} mods an array of modules to load into the application.
+   *     Each item in the array should be the name of a predefined module or a (DI annotated)
+   *     function that will be invoked by the injector as a `config` block.
+   *     See: {@link angular.module modules}

+   * with the {@link auto.$injector $injector}. Many of these functions are also exposed on
+   * {@link angular.Module}.
+   *
+   * An AngularJS **service** is a singleton object created by a **service factory**.  These **service
+   * factories** are functions which, in turn, are created by a **service provider**.
+   * The **service providers** are constructor functions. When instantiated they must contain a
+   * property called `$get`, which holds the **service factory** function.
+   *
+   * When you request a service, the {@link auto.$injector $injector} is responsible for finding the
+   * correct **service provider**, instantiating it and then calling its `$get` **service factory**
+   * function to get the instance of the **service**.
+   *
+   * Often services have no configuration options and there is no need to add methods to the service
+   * provider.  The provider will be no more than a constructor function with a `$get` property. For
+   * these cases the {@link auto.$provide $provide} service has additional helper methods to register
+   * services without specifying a provider.
+   *
+   * * {@link auto.$provide#provider provider(name, provider)} - registers a **service provider** with the
+   *     {@link auto.$injector $injector}
+   * * {@link auto.$provide#constant constant(name, obj)} - registers a value/object that can be accessed by
+   *     providers and services.
+   * * {@link auto.$provide#value value(name, obj)} - registers a value/object that can only be accessed by
+   *     services, not providers.
+   * * {@link auto.$provide#factory factory(name, fn)} - registers a service **factory function**
+   *     that will be wrapped in a **service provider** object, whose `$get` property will contain the
+   *     given factory function.
+   * * {@link auto.$provide#service service(name, Fn)} - registers a **constructor function**
+   *     that will be wrapped in a **service provider** object, whose `$get` property will instantiate
+   *      a new object using the given constructor function.
+   * * {@link auto.$provide#decorator decorator(name, decorFn)} - registers a **decorator function** that

-     * when an animation is detected (and animations are enabled), $animate will do the heavy lifting
-     * to ensure that animation runs with the triggered DOM operation.
-     *
-     * By default $animate doesn't trigger any animations. This is because the `ngAnimate` module isn't

-     * functional. Once active then all structural `ng-` directives will trigger animations as they perform
-     * their DOM-related operations (enter, leave and move). Other directives such as `ngClass`,
-     * `ngShow`, `ngHide` and `ngMessages` also provide support for animations.
-     *
-     * It is recommended that the`$animate` service is always used when executing DOM-related procedures within directives.

+   * Register a **provider function** with the {@link auto.$injector $injector}. Provider functions
+   * are constructor functions, whose instances are responsible for "providing" a factory for a
+   * service.
+   *
+   * Service provider names start with the name of the service they provide followed by `Provider`.
+   * For example, the {@link ng.$log $log} service has a provider called
+   * {@link ng.$logProvider $logProvider}.
+   *
+   * Service provider objects can have additional methods which allow configuration of the provider
+   * and its service. Importantly, you can configure what kind of service is created by the `$get`
+   * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
+   * method {@link ng.$logProvider#debugEnabled debugEnabled}
+   * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
+   * console or not.
+   *
+   * It is possible to inject other providers into the provider function,
+   * but the injected provider must have been defined before the one that requires it.
+   *
+   * @param {string} name The name of the instance. NOTE: the provider will be available under `name +
+                          'Provider'` key.
+   * @param {(Object|function())} provider If the provider is:
+   *
+   *   - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
+   *     {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
+   *   - `Constructor`: a new instance of the provider will be created using
+   *     {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.
+   *
+   * @returns {Object} registered provider instance

+   * Register a **constant service** with the {@link auto.$injector $injector}, such as a string,
+   * a number, an array, an object or a function. Like the {@link auto.$provide#value value}, it is not
+   * possible to inject other services into a constant.
+   *
+   * But unlike {@link auto.$provide#value value}, a constant can be
+   * injected into a module configuration function (see {@link angular.Module#config}) and it cannot
+   * be overridden by an AngularJS {@link auto.$provide#decorator decorator}.
+   *
+   * @param {string} name The name of the constant.
+   * @param {*} value The constant value.
+   * @returns {Object} registered instance
+   *
+   * @example
+   * Here a some examples of creating constants:
+   * ```js
+   *   $provide.constant('SHARD_HEIGHT', 306);
+   *
+   *   $provide.constant('MY_COLOURS', ['red', 'blue', 'grey']);
+   *
+   *   $provide.constant('double', function(value) {
+   *     return value * 2;
+   *   });

+   *
+   * You can find out more about using decorators in the {@link guide/decorators} guide.
+   *
+   * @param {string} name The name of the service to decorate.
+   * @param {Function|Array.} decorator This function will be invoked when the service needs to be
+   *    provided and should return the decorated service instance. The function is called using
+   *    the {@link auto.$injector#invoke injector.invoke} method and is therefore fully injectable.
+   *    Local injection arguments:
+   *
+   *    * `$delegate` - The original service instance, which can be replaced, monkey patched, configured,
+   *      decorated or delegated to.

+   * @example

+     * in the

+     *
+     * It also watches the {@link ng.$location#hash $location.hash()} and automatically scrolls to
+     * match any anchor whenever it changes. This can be disabled by calling
+     * {@link ng.$anchorScrollProvider#disableAutoScrolling $anchorScrollProvider.disableAutoScrolling()}.
+     *
+     * Additionally, you can use its {@link ng.$anchorScroll#yOffset yOffset} property to specify a
+     * vertical scroll-offset (either fixed or dynamic).
+     *
+     * @param {string=} hash The hash specifying the element to scroll to. If omitted, the value of
+     *                       {@link ng.$location#hash $location.hash()} will be used.
+     *
+     * @property {(number|function|jqLite)} yOffset
+     * If set, specifies a vertical scroll-offset. This is often useful when there are fixed
+     * positioned elements at the top of the page, such as navbars, headers etc.
+     *
+     * `yOffset` can be specified in various ways:
+     * - **number**: A fixed number of pixels to be used as offset.


+     * - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return
+     *   a number representing the offset (in pixels).


+     * - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from
+     *   the top of the page to the element's bottom will be used as offset.

+     *   **Note**: The element will be taken into account only as long as its `position` is set to
+     *   `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust
+     *   their height and/or positioning according to the viewport's size.
+     *
+     * 

+     * 

+     * In order for `yOffset` to work properly, scrolling should take place on the document's root and
+     * not some child element.
+     * 

+     *
+     * @example
+       
+         
+           

+             Go to bottom
+              You're at the bottom!

+         * style in `to`, the style in `from` is applied immediately, and no animation is run.
+         * If a JavaScript animation is detected then the provided styles will be given in as function parameters into the `animate`

- * `$templateCache` is a {@link $cacheFactory.Cache Cache object} created by the

- *
- * The first time a template is used, it is loaded in the template cache for quick retrieval. You

- * ```
- *
- * **Note:** the `script` tag containing the template does not need to be included in the `head` of
- * the document, but it must be a descendent of the {@link ng.$rootElement $rootElement} (e.g.
- * element with {@link ngApp} attribute), otherwise the template will be ignored.
- *
- * Adding via the `$templateCache` service:
- *
- * ```js
- * var myApp = angular.module('myApp', []);
- * myApp.run(function($templateCache) {
- *   $templateCache.put('templateId.html', 'This is the content of the template');
- * });
- * ```

-/**
- * @ngdoc service
- * @name $compile
- * @kind function
- *
- * @description
- * Compiles an HTML string or DOM into a template and produces a template function, which
- * can then be used to link {@link ng.$rootScope.Scope `scope`} and the template together.
- *
- * The compilation is a process of walking the DOM tree and matching DOM elements to
- * {@link ng.$compileProvider#directive directives}.
- *
- * 

- * **Note:** This document is an in-depth reference of all directive options.
- * For a gentle introduction to directives with examples of common use cases,
- * see the {@link guide/directive directive guide}.
- * 

- *
- * ## Comprehensive Directive API
- *
- * There are many different options for a directive.
- *
- * The difference resides in the return value of the factory function.
- * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}
- * that defines the directive properties, or just the `postLink` function (all other properties will have
- * the default values).
- *
- * 

- * **Best Practice:** It's recommended to use the "directive definition object" form.
- * 

- *
- * Here's an example directive declared with a Directive Definition Object:
- *
- * ```js
- *   var myModule = angular.module(...);
- *
- *   myModule.directive('directiveName', function factory(injectables) {
- *     var directiveDefinitionObject = {
- *       {@link $compile#-priority- priority}: 0,
- *       {@link $compile#-template- template}: '
', // or // function(tElement, tAttrs) { ... },
- *       // or
- *       // {@link $compile#-templateurl- templateUrl}: 'directive.html', // or // function(tElement, tAttrs) { ... },
- *       {@link $compile#-transclude- transclude}: false,
- *       {@link $compile#-restrict- restrict}: 'A',
- *       {@link $compile#-templatenamespace- templateNamespace}: 'html',
- *       {@link $compile#-scope- scope}: false,
- *       {@link $compile#-controller- controller}: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
- *       {@link $compile#-controlleras- controllerAs}: 'stringIdentifier',
- *       {@link $compile#-bindtocontroller- bindToController}: false,
- *       {@link $compile#-require- require}: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
- *       {@link $compile#-multielement- multiElement}: false,
- *       {@link $compile#-compile- compile}: function compile(tElement, tAttrs, transclude) {
- *         return {
- *            {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
- *            {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
- *         }
- *         // or
- *         // return function postLink( ... ) { ... }
- *       },
- *       // or
- *       // {@link $compile#-link- link}: {
- *       //  {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
- *       //  {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
- *       // }
- *       // or
- *       // {@link $compile#-link- link}: function postLink( ... ) { ... }
- *     };
- *     return directiveDefinitionObject;
- *   });
- * ```
- *
- * 

- * **Note:** Any unspecified options will use the default value. You can see the default values below.
- * 

- *
- * Therefore the above can be simplified as:
- *
- * ```js
- *   var myModule = angular.module(...);
- *
- *   myModule.directive('directiveName', function factory(injectables) {
- *     var directiveDefinitionObject = {
- *       link: function postLink(scope, iElement, iAttrs) { ... }
- *     };
- *     return directiveDefinitionObject;
- *     // or
- *     // return function postLink(scope, iElement, iAttrs) { ... }
- *   });
- * ```
- *
- * ### Life-cycle hooks
- * Directive controllers can provide the following methods that are called by AngularJS at points in the life-cycle of the
- * directive:
- * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
- *   had their bindings initialized (and before the pre & post linking functions for the directives on
- *   this element). This is a good place to put initialization code for your controller.
- * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
- *   `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
- *   object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a
- *   component such as cloning the bound value to prevent accidental mutation of the outer value. Note that this will
- *   also be called when your bindings are initialized.
- * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on
- *   changes. Any actions that you wish to take in response to the changes that you detect must be
- *   invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook
- *   could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not
- *   be detected by AngularJS's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;
- *   if detecting changes, you must store the previous value(s) for comparison to the current values.
- * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing
- *   external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in
- *   the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent
- *   components will have their `$onDestroy()` hook called before child components.
- * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link
- *   function this hook can be used to set up DOM event handlers and do direct DOM manipulation.
- *   Note that child elements that contain `templateUrl` directives will not have been compiled and linked since
- *   they are waiting for their template to load asynchronously and their own compilation and linking has been
- *   suspended until that occurs.
- *
- * #### Comparison with life-cycle hooks in the new Angular
- * The new Angular also uses life-cycle hooks for its components. While the AngularJS life-cycle hooks are similar there are
- * some differences that you should be aware of, especially when it comes to moving your code from AngularJS to Angular:
- *
- * * AngularJS hooks are prefixed with `$`, such as `$onInit`. Angular hooks are prefixed with `ng`, such as `ngOnInit`.
- * * AngularJS hooks can be defined on the controller prototype or added to the controller inside its constructor.
- *   In Angular you can only define hooks on the prototype of the Component class.
- * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in AngularJS than you would to
- *   `ngDoCheck` in Angular.
- * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be
- *   propagated throughout the application.
- *   Angular does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an
- *   error or do nothing depending upon the state of `enableProdMode()`.
- *
- * #### Life-cycle hook examples
- *
- * This example shows how you can check for mutations to a Date object even though the identity of the object
- * has not changed.
- *
- * 
- *   
- *     angular.module('do-check-module', [])
- *       .component('app', {
- *         template:
- *           'Month: ' +
- *           'Date: {{ $ctrl.date }}' +
- *           '',
- *         controller: function() {
- *           this.date = new Date();
- *           this.month = this.date.getMonth();
- *           this.updateDate = function() {
- *             this.date.setMonth(this.month);
- *           };
- *         }
- *       })
- *       .component('test', {
- *         bindings: { date: '<' },
- *         template:
- *           '
{{ $ctrl.log | json }}
',
- *         controller: function() {
- *           var previousValue;
- *           this.log = [];
- *           this.$doCheck = function() {
- *             var currentValue = this.date && this.date.valueOf();
- *             if (previousValue !== currentValue) {
- *               this.log.push('doCheck: date mutated: ' + this.date);
- *               previousValue = currentValue;
- *             }
- *           };
- *         }
- *       });
- *   
- *   
- *     
- *   
- * 
- *
- * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the
- * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large
- * arrays or objects can have a negative impact on your application performance)
- *
- * 
- *   
- *     

- *       
- *       
- *       
{{ items }}

- *       
- *     

- *   
- *   
- *      angular.module('do-check-module', [])
- *        .component('test', {
- *          bindings: { items: '<' },
- *          template:
- *            '
{{ $ctrl.log | json }}
',
- *          controller: function() {
- *            this.log = [];
- *
- *            this.$doCheck = function() {
- *              if (this.items_ref !== this.items) {
- *                this.log.push('doCheck: items changed');
- *                this.items_ref = this.items;
- *              }
- *              if (!angular.equals(this.items_clone, this.items)) {
- *                this.log.push('doCheck: items mutated');
- *                this.items_clone = angular.copy(this.items);
- *              }
- *            };
- *          }
- *        });
- *   
- * 
- *
- *
- * ### Directive Definition Object
- *
- * The directive definition object provides instructions to the {@link ng.$compile
- * compiler}. The attributes are:
- *
- * #### `multiElement`
- * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between
- * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
- * together as the directive elements. It is recommended that this feature be used on directives
- * which are not strictly behavioral (such as {@link ngClick}), and which
- * do not manipulate or replace child nodes (such as {@link ngInclude}).
- *
- * #### `priority`
- * When there are multiple directives defined on a single DOM element, sometimes it
- * is necessary to specify the order in which the directives are applied. The `priority` is used
- * to sort the directives before their `compile` functions get called. Priority is defined as a
- * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
- * are also run in priority order, but post-link functions are run in reverse order. The order
- * of directives with the same priority is undefined. The default priority is `0`.
- *
- * #### `terminal`
- * If set to true then the current `priority` will be the last set of directives
- * which will execute (any directives at the current priority will still execute
- * as the order of execution on same `priority` is undefined). Note that expressions
- * and other directives used in the directive's template will also be excluded from execution.
- *
- * #### `scope`
- * The scope property can be `false`, `true`, or an object:
- *
- * * **`false` (default):** No scope will be created for the directive. The directive will use its
- * parent's scope.
- *
- * * **`true`:** A new child scope that prototypically inherits from its parent will be created for
- * the directive's element. If multiple directives on the same element request a new scope,
- * only one new scope is created.
- *
- * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's template.
- * The 'isolate' scope differs from normal scope in that it does not prototypically
- * inherit from its parent scope. This is useful when creating reusable components, which should not
- * accidentally read or modify data in the parent scope. Note that an isolate scope
- * directive without a `template` or `templateUrl` will not apply the isolate scope
- * to its children elements.
- *
- * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
- * directive's element. These local properties are useful for aliasing values for templates. The keys in
- * the object hash map to the name of the property on the isolate scope; the values define how the property
- * is bound to the parent scope, via matching attributes on the directive's element:
- *
- * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
- *   always a string since DOM attributes are strings. If no `attr` name is specified then the
- *   attribute name is assumed to be the same as the local name. Given `` and the isolate scope definition `scope: { localName:'@myAttr' }`,
- *   the directive's scope property `localName` will reflect the interpolated value of `hello
- *   {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's
- *   scope. The `name` is read from the parent scope (not the directive's scope).
- *
- * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression
- *   passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.
- *   If no `attr` name is specified then the attribute name is assumed to be the same as the local
- *   name. Given `` and the isolate scope definition `scope: {
- *   localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the
- *   value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in
- *   `localModel` and vice versa. If the binding expression is non-assignable, or if the attribute
- *   isn't  optional and doesn't exist, an exception
- *   ({@link error/$compile/nonassign `$compile:nonassign`}) will be thrown upon discovering changes
- *   to the local value, since it will be impossible to sync them back to the parent scope.
- *
- *   By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
- *   method is used for tracking changes, and the equality check is based on object identity.
- *   However, if an object literal or an array literal is passed as the binding expression, the
- *   equality check is done by value (using the {@link angular.equals} function). It's also possible
- *   to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection
- *   `$watchCollection`}: use `=*` or `=*attr`
- *
-  * * `<` or `` and directive definition of
- *   `scope: { localModel:'` and the isolate scope definition `scope: {
- *   localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
- *   the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
- *   via an expression to the parent scope. This can be done by passing a map of local variable names
- *   and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
- *   then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
- *
- * All 4 kinds of bindings (`@`, `=`, `<`, and `&`) can be made optional by adding `?` to the expression.
- * The marker must come after the mode and before the attribute name.
- * See the {@link error/$compile/iscp Invalid Isolate Scope Definition error} for definition examples.
- * This is useful to refine the interface directives provide.
- * One subtle difference between optional and non-optional happens **when the binding attribute is not
- * set**:
- * - the binding is optional: the property will not be defined
- * - the binding is not optional: the property is defined
- *
- * ```js
- *app.directive('testDir', function() {
-    return {
-      scope: {
-        notoptional: '=',
-        optional: '=?',
-      },
-      bindToController: true,
-      controller: function() {
-        this.$onInit = function() {
-          console.log(this.hasOwnProperty('notoptional')) // true
-          console.log(this.hasOwnProperty('optional')) // false
-        }
-      }
+    function cacheStateAndFireUrlChange() {
+      pendingLocation = null;
+      fireStateOrUrlChange();
     }
-  })
- *```
- *
- *
- * ##### Combining directives with different scope defintions
- *
- * In general it's possible to apply more than one directive to one element, but there might be limitations
- * depending on the type of scope required by the directives. The following points will help explain these limitations.
- * For simplicity only two directives are taken into account, but it is also applicable for several directives:
- *
- * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
- * * **child scope** + **no scope** =>  Both directives will share one single child scope
- * * **child scope** + **child scope** =>  Both directives will share one single child scope
- * * **isolated scope** + **no scope** =>  The isolated directive will use it's own created isolated scope. The other directive will use
- * its parent's scope
- * * **isolated scope** + **child scope** =>  **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
- * be applied to the same element.
- * * **isolated scope** + **isolated scope**  =>  **Won't work!** Only one scope can be related to one element. Therefore these directives
- * cannot be applied to the same element.
- *
- *
- * #### `bindToController`
- * This property is used to bind scope properties directly to the controller. It can be either
- * `true` or an object hash with the same format as the `scope` property.
- *
- * When an isolate scope is used for a directive (see above), `bindToController: true` will
- * allow a component to have its properties bound to the controller, rather than to scope.
- *
- * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
- * properties. You can access these bindings once they have been initialized by providing a controller method called
- * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
- * initialized.
- *
- * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.
- * This will set up the scope bindings to the controller directly. Note that `scope` can still be used
- * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate
- * scope (useful for component directives).
- *
- * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.
- *
- *
- * #### `controller`
- * Controller constructor function. The controller is instantiated before the
- * pre-linking phase and can be accessed by other directives (see
- * `require` attribute). This allows the directives to communicate with each other and augment
- * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
- *
- * * `$scope` - Current scope associated with the element
- * * `$element` - Current element
- * * `$attrs` - Current attributes object for the element
- * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
- *   `function([scope], cloneLinkingFn, futureParentElement, slotName)`:
- *    * `scope`: (optional) override the scope.
- *    * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.
- *    * `futureParentElement` (optional):
- *        * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
- *        * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
- *        * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
- *          and when the `cloneLinkingFn` is passed,
- *          as those elements need to created and cloned in a special way when they are defined outside their
- *          usual containers (e.g. like ``).
- *        * See also the `directive.templateNamespace` property.
- *    * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)
- *      then the default transclusion is provided.
- *    The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns
- *    `true` if the specified slot contains content (i.e. one or more DOM nodes).
- *
- * #### `require`
- * Require another directive and inject its controller as the fourth argument to the linking function. The
- * `require` property can be a string, an array or an object:
- * * a **string** containing the name of the directive to pass to the linking function
- * * an **array** containing the names of directives to pass to the linking function. The argument passed to the
- * linking function will be an array of controllers in the same order as the names in the `require` property
- * * an **object** whose property values are the names of the directives to pass to the linking function. The argument
- * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding
- * controllers.
- *
- * If the `require` property is an object and `bindToController` is truthy, then the required controllers are
- * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers
- * have been constructed but before `$onInit` is called.
- * If the name of the required controller is the same as the local name (the key), the name can be
- * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.
- * See the {@link $compileProvider#component} helper for an example of how this can be used.
- * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is
- * raised (unless no link function is specified and the required controllers are not being bound to the directive
- * controller, in which case error checking is skipped). The name can be prefixed with:
- *
- * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
- * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
- * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
- * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
- * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
- *   `null` to the `link` fn if not found.
- * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
- *   `null` to the `link` fn if not found.
- *
- *
- * #### `controllerAs`
- * Identifier name for a reference to the controller in the directive's scope.
- * This allows the controller to be referenced from the directive template. This is especially
- * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
- * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
- * `controllerAs` reference might overwrite a property that already exists on the parent scope.
- *
- *
- * #### `restrict`
- * String of subset of `EACM` which restricts the directive to a specific directive
- * declaration style. If omitted, the defaults (elements and attributes) are used.
- *
- * * `E` - Element name (default): ``
- * * `A` - Attribute (default): `
`
- * * `C` - Class: `
`
- * * `M` - Comment: ``
- *
- *
- * #### `templateNamespace`
- * String representing the document type used by the markup in the template.
- * AngularJS needs this information as those elements need to be created and cloned
- * in a special way when they are defined outside their usual containers like `` and ``.
- *
- * * `html` - All root nodes in the template are HTML. Root nodes may also be
- *   top-level elements such as `` or ``.
- * * `svg` - The root nodes in the template are SVG elements (excluding ``).
- * * `math` - The root nodes in the template are MathML elements (excluding ``).
- *
- * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
- *
- * #### `template`
- * HTML markup that may:
- * * Replace the contents of the directive's element (default).
- * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
- * * Wrap the contents of the directive's element (if `transclude` is true).
- *
- * Value may be:
- *
- * * A string. For example `
{{delete_str}}
`.
- * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
- *   function api below) and returns a string value.
- *
- *
- * #### `templateUrl`
- * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
- *
- * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
- * for later when the template has been resolved.  In the meantime it will continue to compile and link
- * sibling and parent elements as though this element had not contained any directives.
- *
- * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
- * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
- * case when only one deeply nested directive has `templateUrl`.
- *
- * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
- *
- * You can specify `templateUrl` as a string representing the URL or as a function which takes two
- * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
- * a string value representing the url.  In either case, the template URL is passed through {@link
- * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
- *
- *
- * #### `replace`
- * 

- * **Note:** `replace` is deprecated in AngularJS and has been removed in the new Angular (v2+).
- * 

- *
- * Specifies what the template should replace. Defaults to `false`.
- *
- * * `true` - the template will replace the directive's element.
- * * `false` - the template will replace the contents of the directive's element.
- *
- * The replacement process migrates all of the attributes / classes from the old element to the new
- * one. See the {@link guide/directive#template-expanding-directive
- * Directives Guide} for an example.
- *
- * There are very few scenarios where element replacement is required for the application function,
- * the main one being reusable custom components that are used within SVG contexts
- * (because SVG doesn't work with custom elements in the DOM tree).
- *
- * #### `transclude`
- * Extract the contents of the element where the directive appears and make it available to the directive.
- * The contents are compiled and provided to the directive as a **transclusion function**. See the
- * {@link $compile#transclusion Transclusion} section below.
- *
- *
- * #### `compile`
- *
- * ```js
- *   function compile(tElement, tAttrs, transclude) { ... }
- * ```
- *
- * The compile function deals with transforming the template DOM. Since most directives do not do
- * template transformation, it is not used often. The compile function takes the following arguments:
- *
- *   * `tElement` - template element - The element where the directive has been declared. It is
- *     safe to do template transformation on the element and child elements only.
- *
- *   * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
- *     between all directive compile functions.
- *
- *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
- *
- * 

- * **Note:** The template instance and the link instance may be different objects if the template has
- * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
- * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
- * should be done in a linking function rather than in a compile function.
- * 

-
- * 

- * **Note:** The compile function cannot handle directives that recursively use themselves in their
- * own templates or compile functions. Compiling these directives results in an infinite loop and
- * stack overflow errors.
- *
- * This can be avoided by manually using $compile in the postLink function to imperatively compile
- * a directive's template instead of relying on automatic template compilation via `template` or
- * `templateUrl` declaration or manual compilation inside the compile function.
- * 

- *
- * 

- * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
- *   e.g. does not know about the right outer scope. Please use the transclude function that is passed
- *   to the link function instead.
- * 

-
- * A compile function can have a return value which can be either a function or an object.
- *
- * * returning a (post-link) function - is equivalent to registering the linking function via the
- *   `link` property of the config object when the compile function is empty.
- *
- * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
- *   control when a linking function should be called during the linking phase. See info about
- *   pre-linking and post-linking functions below.
- *
- *
- * #### `link`
- * This property is used only if the `compile` property is not defined.
- *
- * ```js
- *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
- * ```
- *
- * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
- * executed after the template has been cloned. This is where most of the directive logic will be
- * put.
- *
- *   * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
- *     directive for registering {@link ng.$rootScope.Scope#$watch watches}.
- *
- *   * `iElement` - instance element - The element where the directive is to be used. It is safe to
- *     manipulate the children of the element only in `postLink` function since the children have
- *     already been linked.
- *
- *   * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
- *     between all directive linking functions.
- *
- *   * `controller` - the directive's required controller instance(s) - Instances are shared
- *     among all directives, which allows the directives to use the controllers as a communication
- *     channel. The exact value depends on the directive's `require` property:
- *       * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
- *       * `string`: the controller instance
- *       * `array`: array of controller instances
- *
- *     If a required controller cannot be found, and it is optional, the instance is `null`,
- *     otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
- *
- *     Note that you can also require the directive's own controller - it will be made available like
- *     any other controller.
- *
- *   * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
- *     This is the same as the `$transclude` parameter of directive controllers,
- *     see {@link ng.$compile#-controller- the controller section for details}.
- *     `function([scope], cloneLinkingFn, futureParentElement)`.
- *
- * #### Pre-linking function
- *
- * Executed before the child elements are linked. Not safe to do DOM transformation since the
- * compiler linking function will fail to locate the correct elements for linking.
- *
- * #### Post-linking function
- *
- * Executed after the child elements are linked.
- *
- * Note that child elements that contain `templateUrl` directives will not have been compiled
- * and linked since they are waiting for their template to load asynchronously and their own
- * compilation and linking has been suspended until that occurs.
- *
- * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
- * for their async templates to be resolved.
- *
- *
- * ### Transclusion
- *
- * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
- * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
- * scope from where they were taken.
- *
- * Transclusion is used (often with {@link ngTransclude}) to insert the
- * original contents of a directive's element into a specified place in the template of the directive.
- * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
- * content has access to the properties on the scope from which it was taken, even if the directive
- * has isolated scope.
- * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
- *
- * This makes it possible for the widget to have private state for its template, while the transcluded
- * content has access to its originating scope.
- *
- * 

- * **Note:** When testing an element transclude directive you must not place the directive at the root of the
- * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
- * Testing Transclusion Directives}.
- * 

- *
- * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the
- * directive's element, the entire element or multiple parts of the element contents:
- *
- * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
- * * `'element'` - transclude the whole of the directive's element including any directives on this
- *   element that defined at a lower priority than this directive. When used, the `template`
- *   property is ignored.
- * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template.
- *
- * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.
- *
- * This object is a map where the keys are the name of the slot to fill and the value is an element selector
- * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)
- * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).
- *
- * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}
- *
- * If the element selector is prefixed with a `?` then that slot is optional.
- *
- * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `` elements to
- * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.
- *
- * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements
- * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call
- * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and
- * injectable into the directive's controller.
- *
- *
- * #### Transclusion Functions
- *
- * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
- * function** to the directive's `link` function and `controller`. This transclusion function is a special
- * **linking function** that will return the compiled contents linked to a new transclusion scope.
- *
- * 

- * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
- * ngTransclude will deal with it for us.
- * 

- *
- * If you want to manually control the insertion and removal of the transcluded content in your directive
- * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
- * object that contains the compiled DOM, which is linked to the correct transclusion scope.
- *
- * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
- * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
- * content and the `scope` is the newly created transclusion scope, which the clone will be linked to.
- *
- * 

- * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function
- * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
- * 

- *
- * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
- * attach function**:
- *
- * ```js
- * var transcludedContent, transclusionScope;
- *
- * $transclude(function(clone, scope) {
- *   element.append(clone);
- *   transcludedContent = clone;
- *   transclusionScope = scope;
- * });
- * ```
- *
- * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
- * associated transclusion scope:
- *
- * ```js
- * transcludedContent.remove();
- * transclusionScope.$destroy();
- * ```
- *
- * 

- * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
- * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
- * then you are also responsible for calling `$destroy` on the transclusion scope.
- * 

- *
- * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
- * automatically destroy their transcluded clones as necessary so you do not need to worry about this if
- * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
- *
- *
- * #### Transclusion Scopes
- *
- * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
- * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
- * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
- * was taken.
- *
- * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
- * like this:
- *
- * ```html
- * 

- *   

- *     

- *     

- *   

- * 

- * ```
- *
- * The `$parent` scope hierarchy will look like this:
- *
-   ```
-   - $rootScope
-     - isolate
-       - transclusion
-   ```
- *
- * but the scopes will inherit prototypically from different scopes to their `$parent`.
- *
-   ```
-   - $rootScope
-     - transclusion
-   - isolate
-   ```
- *
- *
- * ### Attributes
- *
- * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
- * `link()` or `compile()` functions. It has a variety of uses.
- *
- * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:
- *   'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access
- *   to the attributes.
- *
- * * *Directive inter-communication:* All directives share the same instance of the attributes
- *   object which allows the directives to use the attributes object as inter directive
- *   communication.
- *
- * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
- *   allowing other directives to read the interpolated value.
- *
- * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
- *   that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
- *   the only way to easily get the actual value because during the linking phase the interpolation
- *   hasn't been evaluated yet and so the value is at this time set to `undefined`.
- *
- * ```js
- * function linkingFn(scope, elm, attrs, ctrl) {
- *   // get the attribute value
- *   console.log(attrs.ngModel);
- *
- *   // change the attribute
- *   attrs.$set('ngModel', 'new value');
- *
- *   // observe changes to interpolated attribute
- *   attrs.$observe('ngModel', function(value) {
- *     console.log('ngModel has changed value to ' + value);
- *   });
- * }
- * ```
- *
- * ## Example
- *
- * 

- * **Note**: Typically directives are registered with `module.directive`. The example below is
- * to illustrate how `$compile` works.
- * 

- *
- 
-   
-    
-    

-       

-       

-      

-    

-   
-   
-     it('should auto compile', function() {
-       var textarea = $('textarea');
-       var output = $('div[compile]');
-       // The initial state reads 'Hello AngularJS'.
-       expect(output.getText()).toBe('Hello AngularJS');
-       textarea.clear();
-       textarea.sendKeys('{{name}}!');
-       expect(output.getText()).toBe('AngularJS!');
-     });
-   
- 
 
- *
- *
- * @param {string|DOMElement} element Element or HTML string to compile into a template function.
- * @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives - DEPRECATED.
- *
- * 

- * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it
- *   e.g. will not use the right outer scope. Please pass the transclude function as a
- *   `parentBoundTranscludeFn` to the link function instead.
- * 

- *
- * @param {number} maxPriority only apply directives lower than given priority (Only effects the
- *                 root element(s), not their children)
- * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template
- * (a DOM element/tree) to a scope. Where:
- *
- *  * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
- *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
- *  `template` and call the `cloneAttachFn` function allowing the caller to attach the
- *  cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
- *  called as: 
 `cloneAttachFn(clonedElement, scope)` where:
- *
- *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
- *      * `scope` - is the current scope with which the linking function is working with.
- *
- *  * `options` - An optional object hash with linking options. If `options` is provided, then the following
- *  keys may be used to control linking behavior:
- *
- *      * `parentBoundTranscludeFn` - the transclude function made available to
- *        directives; if given, it will be passed through to the link functions of
- *        directives found in `element` during compilation.
- *      * `transcludeControllers` - an object hash with keys that map controller names
- *        to a hash with the key `instance`, which maps to the controller instance;
- *        if given, it will make the controllers available to directives on the compileNode:
- *        ```
- *        {
- *          parent: {
- *            instance: parentControllerInstance
- *          }
- *        }
- *        ```
- *      * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add
- *        the cloned elements; only needed for transcludes that are allowed to contain non html
- *        elements (e.g. SVG elements). See also the directive.controller property.
- *
- * Calling the linking function returns the element of the template. It is either the original
- * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
- *
- * After linking the view is not updated until after a call to $digest which typically is done by
- * AngularJS automatically.
- *
- * If you need access to the bound view, there are two ways to do it:
- *
- * - If you are not asking the linking function to clone the template, create the DOM element(s)
- *   before you send them to the compiler and keep this reference around.
- *   ```js
- *     var element = $compile('
{{total}}
')(scope);
- *   ```
- *
- * - if on the other hand, you need the element to be cloned, the view reference from the original
- *   example would not point to the clone, but rather to the original template that was cloned. In
- *   this case, you can access the clone via the cloneAttachFn:
- *   ```js
- *     var templateElement = angular.element('
{{total}}
'),
- *         scope = ....;
- *
- *     var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
- *       //attach the clone to DOM document at the right place
- *     });
- *
- *     //now we have reference to the cloned DOM via `clonedElement`
- *   ```
- *
- *
- * For information on how the compiler works, see the
- * {@link guide/compiler AngularJS HTML Compiler} section of the Developer Guide.
- *
- * @knownIssue
- *
- * ### Double Compilation
- *
-   Double compilation occurs when an already compiled part of the DOM gets
-   compiled again. This is an undesired effect and can lead to misbehaving directives, performance issues,
-   and memory leaks. Refer to the Compiler Guide {@link guide/compiler#double-compilation-and-how-to-avoid-it
-   section on double compilation} for an in-depth explanation and ways to avoid it.
+    // This variable should be used *only* inside the cacheState function.
+    var lastCachedState = null;
+    function cacheState() {
+      // This should be the only place in $browser where `history.state` is read.
+      cachedState = getCurrentState();
+      cachedState = isUndefined(cachedState) ? null : cachedState;
 
- * @knownIssue
+      // Prevent callbacks fo fire twice if both hashchange & popstate were fired.
+      if (equals(cachedState, lastCachedState)) {
+        cachedState = lastCachedState;
+      }
 
-   ### Issues with `replace: true`
- *
- * 

- *   **Note**: {@link $compile#-replace- `replace: true`} is deprecated and not recommended to use,
- *   mainly due to the issues listed here. It has been completely removed in the new Angular.
- * 

- *
- * #### Attribute values are not merged
- *
- * When a `replace` directive encounters the same attribute on the original and the replace node,
- * it will simply deduplicate the attribute and join the values with a space or with a `;` in case of
- * the `style` attribute.
- * ```html
- * Original Node: 
- * Replace Template: 
- * Result: 
- * ```
- *
- * That means attributes that contain AngularJS expressions will not be merged correctly, e.g.
- * {@link ngShow} or {@link ngClass} will cause a {@link $parse} error:
- *
- * ```html
- * Original Node: 
- * Replace Template: 
- * Result:

- * #### Directives are not deduplicated before compilation
- *
- * When the original node and the replace template declare the same directive(s), they will be
- * {@link guide/compiler#double-compilation-and-how-to-avoid-it compiled twice} because the compiler
- * does not deduplicate them. In many cases, this is not noticable, but e.g. {@link ngModel} will
- * attach `$formatters` and `$parsers` twice.
- *
- * See issue [#2573](https://github.com/angular/angular.js/issues/2573).
- *
- * #### `transclude: element` in the replace template root can have unexpected effects
- *
- * When the replace template has a directive at the root node that uses
- * {@link $compile#-transclude- `transclude: element`}, e.g.
- * {@link ngIf} or {@link ngRepeat}, the DOM structure or scope inheritance can be incorrect.
- * See the following issues:
- *
- * - Incorrect scope on replaced element:
- * [#9837](https://github.com/angular/angular.js/issues/9837)
- * - Different DOM between `template` and `templateUrl`:

- * @ngdoc directive
- * @name ngProp
- * @restrict A
- * @element ANY
- *
- * @usage
- *
- * ```html
- * 
- * 
- * ```
- *
- * or with uppercase letters in property (e.g. "propName"):
- *
- *
- * ```html
- * 
- * 
- * ```
- *
- *
- * @description
- * The `ngProp` directive binds an expression to a DOM element property.
- * `ngProp` allows writing to arbitrary properties by including
- * the property name in the attribute, e.g. `ng-prop-value="'my value'"` binds 'my value' to
- * the `value` property.
- *
- * Usually, it's not necessary to write to properties in AngularJS, as the built-in directives
- * handle the most common use cases (instead of the above example, you would use {@link ngValue}).
- *
- * However, [custom elements](https://developer.mozilla.org/docs/Web/Web_Components/Using_custom_elements)
- * often use custom properties to hold data, and `ngProp` can be used to provide input to these
- * custom elements.
- *
- * ## Binding to camelCase properties
- *
- * Since HTML attributes are case-insensitive, camelCase properties like `innerHTML` must be escaped.
- * AngularJS uses the underscore (_) in front of a character to indicate that it is uppercase, so
- * `innerHTML`  must be written as `ng-prop-inner_h_t_m_l="expression"` (Note that this is just an
- * example, and for binding HTML {@link ngBindHtml} should be used.
- *
- * ## Security
- *
- * Binding expressions to arbitrary properties poses a security risk, as  properties like `innerHTML`
- * can insert potentially dangerous HTML into the application, e.g. script tags that execute
- * malicious code.
- * For this reason, `ngProp` applies Strict Contextual Escaping with the {@link ng.$sce $sce service}.
- * This means vulnerable properties require their content to be "trusted", based on the
- * context of the property. For example, the `innerHTML` is in the `HTML` context, and the
- * `iframe.src` property is in the `RESOURCE_URL` context, which requires that values written to
- * this property are trusted as a `RESOURCE_URL`.
- *
- * This can be set explicitly by calling $sce.trustAs(type, value) on the value that is
- * trusted before passing it to the `ng-prop-*` directive. There are exist shorthand methods for
- * each context type in the form of {@link ng.$sce#trustAsResourceUrl $sce.trustAsResourceUrl()} et al.
- *
- * In some cases you can also rely upon automatic sanitization of untrusted values - see below.
- *
- * Based on the context, other options may exist to mark a value as trusted / configure the behavior
- * of {@link ng.$sce}. For example, to restrict the `RESOURCE_URL` context to specific origins, use
- * the {@link $sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist()}
- * and {@link $sceDelegateProvider#resourceUrlBlacklist resourceUrlBlacklist()}.
- *
- * {@link ng.$sce#what-trusted-context-types-are-supported- Find out more about the different context types}.
- *
- * ### HTML Sanitization
- *
- * By default, `$sce` will throw an error if it detects untrusted HTML content, and will not bind the
- * content.
- * However, if you include the {@link ngSanitize ngSanitize module}, it will try to sanitize the
- * potentially dangerous HTML, e.g. strip non-whitelisted tags and attributes when binding to
- * `innerHTML`.
- *
- * @example
- * ### Binding to different contexts
- *
- * 
- *   
- *     angular.module('exampleNgProp', [])
- *       .component('main', {
- *         templateUrl: 'main.html',
- *         controller: function($sce) {
- *           this.safeContent = 'Safe content';
- *           this.unsafeContent = '';
- *           this.trustedUnsafeContent = $sce.trustAsHtml(this.unsafeContent);
- *         }
- *       });
- *   
- *   
- *     

- *       

- *         Binding to a property without security context:
- *         

- *         innerText (safeContent)
- *       

- *
- *       

- *         "Safe" content that requires a security context will throw because the contents could potentially be dangerous ...
- *         

- *         innerHTML (safeContent)
- *       

- *
- *       

- *         ... so that actually dangerous content cannot be executed:
- *         

- *         innerHTML (unsafeContent)
- *       

- *
- *       

- *         ... but unsafe Content that has been trusted explicitly works - only do this if you are 100% sure!
- *         

- *         innerHTML (trustedUnsafeContent)
- *       

- *     

- *   
- *   
- *     

- *   
- *   
- *     .prop-unit {
- *       margin-bottom: 10px;
- *     }
- *
- *     .prop-binding {
- *       min-height: 30px;
- *       border: 1px solid blue;
- *     }
- *
- *     .prop-note {
- *       font-family: Monospace;
- *     }
- *   
- * 
- *
- *
- * @example
- * ### Binding to innerHTML with ngSanitize
- *
- * 
- *   
- *     angular.module('exampleNgProp', ['ngSanitize'])
- *       .component('main', {
- *         templateUrl: 'main.html',
- *         controller: function($sce) {
- *           this.safeContent = 'Safe content';
- *           this.unsafeContent = '';
- *           this.trustedUnsafeContent = $sce.trustAsHtml(this.unsafeContent);
- *         }
- *       });
- *   
- *   
- *     

- *       

- *         "Safe" content will be sanitized ...
- *         

- *         innerHTML (safeContent)
- *       

- *
- *       

- *         ... as will dangerous content:
- *         

- *         innerHTML (unsafeContent)
- *       

- *
- *       

- *         ... and content that has been trusted explicitly works the same as without ngSanitize:
- *         

- *         innerHTML (trustedUnsafeContent)
- *       

- *     

- *

- *
- * or with uppercase letters in property (e.g. "eventName"):

- *
- * @description
- * The `ngOn` directive adds an event listener to a DOM element via
- * {@link angular.element angular.element().on()}, and evaluates an expression when the event is
- * fired.
- * `ngOn` allows adding listeners for arbitrary events by including
- * the event name in the attribute, e.g. `ng-on-drop="onDrop()"` executes the 'onDrop()' expression
- * when the `drop` event is fired.
- *
- * AngularJS provides specific directives for many events, such as {@link ngClick}, so in most
- * cases it is not necessary to use `ngOn`. However, AngularJS does not support all events
- * (e.g. the `drop` event in the example above), and new events might be introduced in later DOM
- * standards.
- *
- * Another use-case for `ngOn` is listening to
- * [custom events](https://developer.mozilla.org/docs/Web/Guide/Events/Creating_and_triggering_events)
- * fired by
- * [custom elements](https://developer.mozilla.org/docs/Web/Web_Components/Using_custom_elements).
- *
- * ## Binding to camelCase properties
- *
- * Since HTML attributes are case-insensitive, camelCase properties like `myEvent` must be escaped.
- * AngularJS uses the underscore (_) in front of a character to indicate that it is uppercase, so
- * `myEvent` must be written as `ng-on-my_event="expression"`.
- *
- * @example
- * ### Bind to built-in DOM events
- *
- * 
- *   
- *     angular.module('exampleNgOn', [])
- *       .component('main', {
- *         templateUrl: 'main.html',
- *         controller: function() {
- *           this.clickCount = 0;
- *           this.mouseoverCount = 0;
- *
- *           this.loadingState = 0;
- *         }
- *       });
- *   
- *   
- *     

- *       This is equivalent to `ngClick` and `ngMouseover`:

- *       

- *       clickCount: {{$ctrl.clickCount}}

- *       mouseover: {{$ctrl.mouseoverCount}}
- *
- *       

- *
- *       For the `error` and `load` event on images no built-in AngularJS directives exist:

- *       

- *       

- *         Image is loading
- *         Image load error
- *         Image loaded successfully
- *       

- *     

- *   
- *   
- *     

- *

- * ### Bind to custom DOM events

- *           };

    * @description
-   * Register a **component definition** with the compiler. This is a shorthand for registering a special
-   * type of directive, which represents a self-contained UI component in your application. Such components
-   * are always isolated (i.e. `scope: {}`) and are always restricted to elements (i.e. `restrict: 'E'`).
+   * Factory that constructs {@link $cacheFactory.Cache Cache} objects and gives access to
+   * them.
    *
-   * Component definitions are very simple and do not require as much configuration as defining general
-   * directives. Component definitions usually consist only of a template and a controller backing it.
+   * ```js
    *
-   * In order to make the definition easier, components enforce best practices like use of `controllerAs`,
-   * `bindToController`. They always have **isolate scope** and are restricted to elements.
+   *  var cache = $cacheFactory('cacheId');
+   *  expect($cacheFactory.get('cacheId')).toBe(cache);
+   *  expect($cacheFactory.get('noSuchCacheId')).not.toBeDefined();
    *
-   * Here are a few examples of how you would usually define components:
+   *  cache.put("key", "value");
+   *  cache.put("another key", "another value");
    *
-   * ```js
-   *   var myMod = angular.module(...);
-   *   myMod.component('myComp', {
-   *     template: '
My name is {{$ctrl.name}}
',
-   *     controller: function() {
-   *       this.name = 'shahar';
-   *     }
-   *   });
+   *  // We've specified no options on creation
+   *  expect(cache.info()).toEqual({id: 'cacheId', size: 2});
    *
-   *   myMod.component('myComp', {
-   *     template: '
My name is {{$ctrl.name}}
',
-   *     bindings: {name: '@'}
-   *   });
+   * ```
    *
-   *   myMod.component('myComp', {
-   *     templateUrl: 'views/my-comp.html',
-   *     controller: 'MyCtrl',
-   *     controllerAs: 'ctrl',
-   *     bindings: {name: '@'}
-   *   });
    *
-   * ```
-   * For more examples, and an in-depth guide, see the {@link guide/component component guide}.
+   * @param {string} cacheId Name or id of the newly created cache.
+   * @param {object=} options Options object that specifies the cache behavior. Properties:
    *
-   * 

-   * See also {@link ng.$compileProvider#directive $compileProvider.directive()}.
+   *   - `{number=}` `capacity` — turns the cache into LRU cache.
+   *
+   * @returns {object} Newly created cache object with the following set of methods:
+   *
+   * - `{object}` `info()` — Returns id, size, and options of cache.
+   * - `{{*}}` `put({string} key, {*} value)` — Puts a new key-value pair into the cache and returns
+   *   it.
+   * - `{{*}}` `get({string} key)` — Returns cached value for `key` or undefined for cache miss.
+   * - `{void}` `remove({string} key)` — Removes a key-value pair from the cache.
+   * - `{void}` `removeAll()` — Removes all cached values.
+   * - `{void}` `destroy()` — Removes references to this cache from $cacheFactory.

+   * **Note:** This document is an in-depth reference of all directive options.
+   * For a gentle introduction to directives with examples of common use cases,
+   * see the {@link guide/directive directive guide}.
+   * 

+   *
+   * ## Comprehensive Directive API
+   *
+   * There are many different options for a directive.
+   *
+   * The difference resides in the return value of the factory function.
+   * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}
+   * that defines the directive properties, or just the `postLink` function (all other properties will have
+   * the default values).
+   *
+   * 

+   * **Best Practice:** It's recommended to use the "directive definition object" form.
+   * 

+   *
+   * Here's an example directive declared with a Directive Definition Object:
+   *
+   * ```js
+   *   var myModule = angular.module(...);
+   *
+   *   myModule.directive('directiveName', function factory(injectables) {
+   *     var directiveDefinitionObject = {
+   *       {@link $compile#-priority- priority}: 0,
+   *       {@link $compile#-template- template}: '
', // or // function(tElement, tAttrs) { ... },
+   *       // or
+   *       // {@link $compile#-templateurl- templateUrl}: 'directive.html', // or // function(tElement, tAttrs) { ... },
+   *       {@link $compile#-transclude- transclude}: false,
+   *       {@link $compile#-restrict- restrict}: 'A',
+   *       {@link $compile#-templatenamespace- templateNamespace}: 'html',
+   *       {@link $compile#-scope- scope}: false,
+   *       {@link $compile#-controller- controller}: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
+   *       {@link $compile#-controlleras- controllerAs}: 'stringIdentifier',
+   *       {@link $compile#-bindtocontroller- bindToController}: false,
+   *       {@link $compile#-require- require}: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
+   *       {@link $compile#-multielement- multiElement}: false,
+   *       {@link $compile#-compile- compile}: function compile(tElement, tAttrs, transclude) {
+   *         return {
+   *            {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
+   *            {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
+   *         }
+   *         // or
+   *         // return function postLink( ... ) { ... }
+   *       },
+   *       // or
+   *       // {@link $compile#-link- link}: {
+   *       //  {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
+   *       //  {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
+   *       // }
+   *       // or
+   *       // {@link $compile#-link- link}: function postLink( ... ) { ... }
+   *     };
+   *     return directiveDefinitionObject;
+   *   });
+   * ```
+   *
+   * 

+   * **Note:** Any unspecified options will use the default value. You can see the default values below.
+   * 

+   *
+   * Therefore the above can be simplified as:
+   *
+   * ```js
+   *   var myModule = angular.module(...);
+   *
+   *   myModule.directive('directiveName', function factory(injectables) {
+   *     var directiveDefinitionObject = {
+   *       link: function postLink(scope, iElement, iAttrs) { ... }
+   *     };
+   *     return directiveDefinitionObject;
+   *     // or
+   *     // return function postLink(scope, iElement, iAttrs) { ... }
+   *   });
+   * ```
+   *
+   * ### Life-cycle hooks
+   * Directive controllers can provide the following methods that are called by AngularJS at points in the life-cycle of the
+   * directive:
+   * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
+   *   had their bindings initialized (and before the pre & post linking functions for the directives on
+   *   this element). This is a good place to put initialization code for your controller.
+   * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
+   *   `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
+   *   object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a
+   *   component such as cloning the bound value to prevent accidental mutation of the outer value. Note that this will
+   *   also be called when your bindings are initialized.
+   * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on
+   *   changes. Any actions that you wish to take in response to the changes that you detect must be
+   *   invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook
+   *   could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not
+   *   be detected by AngularJS's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;
+   *   if detecting changes, you must store the previous value(s) for comparison to the current values.
+   * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing
+   *   external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in
+   *   the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent
+   *   components will have their `$onDestroy()` hook called before child components.
+   * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link
+   *   function this hook can be used to set up DOM event handlers and do direct DOM manipulation.
+   *   Note that child elements that contain `templateUrl` directives will not have been compiled and linked since
+   *   they are waiting for their template to load asynchronously and their own compilation and linking has been
+   *   suspended until that occurs.
+   *
+   * #### Comparison with life-cycle hooks in the new Angular
+   * The new Angular also uses life-cycle hooks for its components. While the AngularJS life-cycle hooks are similar there are
+   * some differences that you should be aware of, especially when it comes to moving your code from AngularJS to Angular:
+   *
+   * * AngularJS hooks are prefixed with `$`, such as `$onInit`. Angular hooks are prefixed with `ng`, such as `ngOnInit`.
+   * * AngularJS hooks can be defined on the controller prototype or added to the controller inside its constructor.
+   *   In Angular you can only define hooks on the prototype of the Component class.
+   * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in AngularJS than you would to
+   *   `ngDoCheck` in Angular.
+   * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be
+   *   propagated throughout the application.
+   *   Angular does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an
+   *   error or do nothing depending upon the state of `enableProdMode()`.
+   *
+   * #### Life-cycle hook examples
+   *
+   * This example shows how you can check for mutations to a Date object even though the identity of the object
+   * has not changed.
+   *
+   * 
+   *   
+   *     angular.module('do-check-module', [])
+   *       .component('app', {
+   *         template:
+   *           'Month: ' +
+   *           'Date: {{ $ctrl.date }}' +
+   *           '',
+   *         controller: function() {
+   *           this.date = new Date();
+   *           this.month = this.date.getMonth();
+   *           this.updateDate = function() {
+   *             this.date.setMonth(this.month);
+   *           };
+   *         }
+   *       })
+   *       .component('test', {
+   *         bindings: { date: '<' },
+   *         template:
+   *           '
{{ $ctrl.log | json }}
',
+   *         controller: function() {
+   *           var previousValue;
+   *           this.log = [];
+   *           this.$doCheck = function() {
+   *             var currentValue = this.date && this.date.valueOf();
+   *             if (previousValue !== currentValue) {
+   *               this.log.push('doCheck: date mutated: ' + this.date);
+   *               previousValue = currentValue;
+   *             }
+   *           };
+   *         }
+   *       });
+   *   
+   *   
+   *     
+   *   
+   * 
+   *
+   * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the
+   * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large
+   * arrays or objects can have a negative impact on your application performance)
+   *
+   * 
+   *   
+   *     

+   *       
+   *       
+   *

+   *          template:
+   *            '
{{ $ctrl.log | json }}
',

+   *                this.log.push('doCheck: items changed');
+   *                this.items_ref = this.items;
+   *              }
+   *              if (!angular.equals(this.items_clone, this.items)) {

+   *            };
+   *          }
+   *        });
+   *   
+   * 
+   *
+   *
+   * ### Directive Definition Object
+   *
+   * The directive definition object provides instructions to the {@link ng.$compile
+   * compiler}. The attributes are:
+   *
+   * #### `multiElement`
+   * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between
+   * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
+   * together as the directive elements. It is recommended that this feature be used on directives
+   * which are not strictly behavioral (such as {@link ngClick}), and which
+   * do not manipulate or replace child nodes (such as {@link ngInclude}).
+   *
+   * #### `priority`
+   * When there are multiple directives defined on a single DOM element, sometimes it
+   * is necessary to specify the order in which the directives are applied. The `priority` is used
+   * to sort the directives before their `compile` functions get called. Priority is defined as a
+   * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
+   * are also run in priority order, but post-link functions are run in reverse order. The order
+   * of directives with the same priority is undefined. The default priority is `0`.
+   *
+   * #### `terminal`
+   * If set to true then the current `priority` will be the last set of directives
+   * which will execute (any directives at the current priority will still execute
+   * as the order of execution on same `priority` is undefined). Note that expressions
+   * and other directives used in the directive's template will also be excluded from execution.
+   *
+   * #### `scope`
+   * The scope property can be `false`, `true`, or an object:
+   *
+   * * **`false` (default):** No scope will be created for the directive. The directive will use its
+   * parent's scope.
+   *
+   * * **`true`:** A new child scope that prototypically inherits from its parent will be created for
+   * the directive's element. If multiple directives on the same element request a new scope,
+   * only one new scope is created.
+   *
+   * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's template.
+   * The 'isolate' scope differs from normal scope in that it does not prototypically
+   * inherit from its parent scope. This is useful when creating reusable components, which should not
+   * accidentally read or modify data in the parent scope. Note that an isolate scope
+   * directive without a `template` or `templateUrl` will not apply the isolate scope
+   * to its children elements.
+   *
+   * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
+   * directive's element. These local properties are useful for aliasing values for templates. The keys in
+   * the object hash map to the name of the property on the isolate scope; the values define how the property
+   * is bound to the parent scope, via matching attributes on the directive's element:
+   *
+   * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
+   *   always a string since DOM attributes are strings. If no `attr` name is specified then the
+   *   attribute name is assumed to be the same as the local name. Given `` and the isolate scope definition `scope: { localName:'@myAttr' }`,
+   *   the directive's scope property `localName` will reflect the interpolated value of `hello
+   *   {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's
+   *   scope. The `name` is read from the parent scope (not the directive's scope).
+   *
+   * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression
+   *   passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.
+   *   If no `attr` name is specified then the attribute name is assumed to be the same as the local
+   *   name. Given `` and the isolate scope definition `scope: {
+   *   localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the
+   *   value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in
+   *   `localModel` and vice versa. If the binding expression is non-assignable, or if the attribute
+   *   isn't  optional and doesn't exist, an exception
+   *   ({@link error/$compile/nonassign `$compile:nonassign`}) will be thrown upon discovering changes
+   *   to the local value, since it will be impossible to sync them back to the parent scope.
+   *
+   *   By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
+   *   method is used for tracking changes, and the equality check is based on object identity.
+   *   However, if an object literal or an array literal is passed as the binding expression, the
+   *   equality check is done by value (using the {@link angular.equals} function). It's also possible
+   *   to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection
+   *   `$watchCollection`}: use `=*` or `=*attr`
+   *
+    * * `<` or `` and directive definition of
+   *   `scope: { localModel:'` and the isolate scope definition `scope: {
+   *   localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
+   *   the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
+   *   via an expression to the parent scope. This can be done by passing a map of local variable names
+   *   and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
+   *   then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
+   *
+   * All 4 kinds of bindings (`@`, `=`, `<`, and `&`) can be made optional by adding `?` to the expression.
+   * The marker must come after the mode and before the attribute name.
+   * See the {@link error/$compile/iscp Invalid Isolate Scope Definition error} for definition examples.
+   * This is useful to refine the interface directives provide.
+   * One subtle difference between optional and non-optional happens **when the binding attribute is not
+   * set**:
+   * - the binding is optional: the property will not be defined
+   * - the binding is not optional: the property is defined
+   *
+   * ```js
+   *app.directive('testDir', function() {
+      return {
+        scope: {
+          notoptional: '=',
+          optional: '=?',
+        },
+        bindToController: true,
+        controller: function() {
+          this.$onInit = function() {
+            console.log(this.hasOwnProperty('notoptional')) // true
+            console.log(this.hasOwnProperty('optional')) // false
+          }
+        }
+      }
+    })
+   *```
+   *
+   *
+   * ##### Combining directives with different scope defintions
+   *
+   * In general it's possible to apply more than one directive to one element, but there might be limitations
+   * depending on the type of scope required by the directives. The following points will help explain these limitations.
+   * For simplicity only two directives are taken into account, but it is also applicable for several directives:
+   *
+   * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
+   * * **child scope** + **no scope** =>  Both directives will share one single child scope
+   * * **child scope** + **child scope** =>  Both directives will share one single child scope
+   * * **isolated scope** + **no scope** =>  The isolated directive will use it's own created isolated scope. The other directive will use
+   * its parent's scope
+   * * **isolated scope** + **child scope** =>  **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
+   * be applied to the same element.
+   * * **isolated scope** + **isolated scope**  =>  **Won't work!** Only one scope can be related to one element. Therefore these directives
+   * cannot be applied to the same element.
+   *
+   *
+   * #### `bindToController`
+   * This property is used to bind scope properties directly to the controller. It can be either
+   * `true` or an object hash with the same format as the `scope` property.
+   *
+   * When an isolate scope is used for a directive (see above), `bindToController: true` will
+   * allow a component to have its properties bound to the controller, rather than to scope.
+   *
+   * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
+   * properties. You can access these bindings once they have been initialized by providing a controller method called
+   * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
+   * initialized.
+   *
+   * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.
+   * This will set up the scope bindings to the controller directly. Note that `scope` can still be used
+   * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate
+   * scope (useful for component directives).
+   *
+   * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.
+   *
+   *
+   * #### `controller`
+   * Controller constructor function. The controller is instantiated before the
+   * pre-linking phase and can be accessed by other directives (see
+   * `require` attribute). This allows the directives to communicate with each other and augment
+   * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
+   *
+   * * `$scope` - Current scope associated with the element
+   * * `$element` - Current element
+   * * `$attrs` - Current attributes object for the element
+   * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
+   *   `function([scope], cloneLinkingFn, futureParentElement, slotName)`:
+   *    * `scope`: (optional) override the scope.
+   *    * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.
+   *    * `futureParentElement` (optional):
+   *        * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
+   *        * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
+   *        * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
+   *          and when the `cloneLinkingFn` is passed,
+   *          as those elements need to created and cloned in a special way when they are defined outside their
+   *          usual containers (e.g. like ``).
+   *        * See also the `directive.templateNamespace` property.
+   *    * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)
+   *      then the default transclusion is provided.
+   *    The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns
+   *    `true` if the specified slot contains content (i.e. one or more DOM nodes).
+   *
+   * #### `require`
+   * Require another directive and inject its controller as the fourth argument to the linking function. The
+   * `require` property can be a string, an array or an object:
+   * * a **string** containing the name of the directive to pass to the linking function
+   * * an **array** containing the names of directives to pass to the linking function. The argument passed to the
+   * linking function will be an array of controllers in the same order as the names in the `require` property
+   * * an **object** whose property values are the names of the directives to pass to the linking function. The argument
+   * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding
+   * controllers.
+   *
+   * If the `require` property is an object and `bindToController` is truthy, then the required controllers are
+   * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers
+   * have been constructed but before `$onInit` is called.
+   * If the name of the required controller is the same as the local name (the key), the name can be
+   * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.
+   * See the {@link $compileProvider#component} helper for an example of how this can be used.
+   * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is
+   * raised (unless no link function is specified and the required controllers are not being bound to the directive
+   * controller, in which case error checking is skipped). The name can be prefixed with:
+   *
+   * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
+   * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
+   * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
+   * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
+   * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
+   *   `null` to the `link` fn if not found.
+   * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
+   *   `null` to the `link` fn if not found.
+   *
+   *
+   * #### `controllerAs`
+   * Identifier name for a reference to the controller in the directive's scope.
+   * This allows the controller to be referenced from the directive template. This is especially
+   * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
+   * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
+   * `controllerAs` reference might overwrite a property that already exists on the parent scope.
+   *
+   *
+   * #### `restrict`
+   * String of subset of `EACM` which restricts the directive to a specific directive
+   * declaration style. If omitted, the defaults (elements and attributes) are used.
+   *
+   * * `E` - Element name (default): ``
+   * * `A` - Attribute (default): `
`
+   * * `C` - Class: `
`
+   * * `M` - Comment: ``
+   *
+   *
+   * #### `templateNamespace`
+   * String representing the document type used by the markup in the template.
+   * AngularJS needs this information as those elements need to be created and cloned
+   * in a special way when they are defined outside their usual containers like `` and ``.
+   *
+   * * `html` - All root nodes in the template are HTML. Root nodes may also be
+   *   top-level elements such as `` or ``.
+   * * `svg` - The root nodes in the template are SVG elements (excluding ``).
+   * * `math` - The root nodes in the template are MathML elements (excluding ``).
+   *
+   * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
+   *
+   * #### `template`
+   * HTML markup that may:
+   * * Replace the contents of the directive's element (default).
+   * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
+   * * Wrap the contents of the directive's element (if `transclude` is true).
+   *
+   * Value may be:
+   *
+   * * A string. For example `
{{delete_str}}
`.
+   * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
+   *   function api below) and returns a string value.
+   *
+   *
+   * #### `templateUrl`
+   * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
+   *
+   * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
+   * for later when the template has been resolved.  In the meantime it will continue to compile and link
+   * sibling and parent elements as though this element had not contained any directives.
+   *
+   * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
+   * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
+   * case when only one deeply nested directive has `templateUrl`.
+   *
+   * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
+   *
+   * You can specify `templateUrl` as a string representing the URL or as a function which takes two
+   * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
+   * a string value representing the url.  In either case, the template URL is passed through {@link
+   * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
+   *
+   *
+   * #### `replace`
+   * 

+   * **Note:** `replace` is deprecated in AngularJS and has been removed in the new Angular (v2+).
+   * 

+   *
+   * Specifies what the template should replace. Defaults to `false`.
+   *
+   * * `true` - the template will replace the directive's element.
+   * * `false` - the template will replace the contents of the directive's element.
+   *
+   * The replacement process migrates all of the attributes / classes from the old element to the new
+   * one. See the {@link guide/directive#template-expanding-directive
+   * Directives Guide} for an example.
+   *
+   * There are very few scenarios where element replacement is required for the application function,
+   * the main one being reusable custom components that are used within SVG contexts
+   * (because SVG doesn't work with custom elements in the DOM tree).
+   *
+   * #### `transclude`
+   * Extract the contents of the element where the directive appears and make it available to the directive.
+   * The contents are compiled and provided to the directive as a **transclusion function**. See the
+   * {@link $compile#transclusion Transclusion} section below.
+   *
+   *
+   * #### `compile`
+   *
+   * ```js
+   *   function compile(tElement, tAttrs, transclude) { ... }
+   * ```
+   *
+   * The compile function deals with transforming the template DOM. Since most directives do not do
+   * template transformation, it is not used often. The compile function takes the following arguments:
+   *
+   *   * `tElement` - template element - The element where the directive has been declared. It is
+   *     safe to do template transformation on the element and child elements only.
+   *
+   *   * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
+   *     between all directive compile functions.
+   *
+   *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
+   *
+   * 

+   * **Note:** The template instance and the link instance may be different objects if the template has
+   * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
+   * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
+   * should be done in a linking function rather than in a compile function.
+   * 

+  
+   * 

+   * **Note:** The compile function cannot handle directives that recursively use themselves in their
+   * own templates or compile functions. Compiling these directives results in an infinite loop and
+   * stack overflow errors.
+   *
+   * This can be avoided by manually using $compile in the postLink function to imperatively compile
+   * a directive's template instead of relying on automatic template compilation via `template` or
+   * `templateUrl` declaration or manual compilation inside the compile function.
+   * 

+   *
+   * 

+   * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
+   *   e.g. does not know about the right outer scope. Please use the transclude function that is passed
+   *   to the link function instead.
+   * 

+  
+   * A compile function can have a return value which can be either a function or an object.
+   *
+   * * returning a (post-link) function - is equivalent to registering the linking function via the
+   *   `link` property of the config object when the compile function is empty.
+   *
+   * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
+   *   control when a linking function should be called during the linking phase. See info about
+   *   pre-linking and post-linking functions below.
+   *
+   *
+   * #### `link`
+   * This property is used only if the `compile` property is not defined.
+   *
+   * ```js
+   *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
+   * ```
+   *
+   * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
+   * executed after the template has been cloned. This is where most of the directive logic will be
+   * put.
+   *
+   *   * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
+   *     directive for registering {@link ng.$rootScope.Scope#$watch watches}.
+   *
+   *   * `iElement` - instance element - The element where the directive is to be used. It is safe to
+   *     manipulate the children of the element only in `postLink` function since the children have
+   *     already been linked.
+   *
+   *   * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
+   *     between all directive linking functions.
+   *
+   *   * `controller` - the directive's required controller instance(s) - Instances are shared
+   *     among all directives, which allows the directives to use the controllers as a communication
+   *     channel. The exact value depends on the directive's `require` property:
+   *       * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
+   *       * `string`: the controller instance
+   *       * `array`: array of controller instances
+   *
+   *     If a required controller cannot be found, and it is optional, the instance is `null`,
+   *     otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
+   *
+   *     Note that you can also require the directive's own controller - it will be made available like
+   *     any other controller.
+   *
+   *   * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
+   *     This is the same as the `$transclude` parameter of directive controllers,
+   *     see {@link ng.$compile#-controller- the controller section for details}.
+   *     `function([scope], cloneLinkingFn, futureParentElement)`.
+   *
+   * #### Pre-linking function
+   *
+   * Executed before the child elements are linked. Not safe to do DOM transformation since the
+   * compiler linking function will fail to locate the correct elements for linking.
+   *
+   * #### Post-linking function
+   *
+   * Executed after the child elements are linked.
+   *
+   * Note that child elements that contain `templateUrl` directives will not have been compiled
+   * and linked since they are waiting for their template to load asynchronously and their own
+   * compilation and linking has been suspended until that occurs.
+   *
+   * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
+   * for their async templates to be resolved.
+   *
+   *
+   * ### Transclusion
+   *
+   * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
+   * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
+   * scope from where they were taken.
+   *
+   * Transclusion is used (often with {@link ngTransclude}) to insert the
+   * original contents of a directive's element into a specified place in the template of the directive.
+   * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
+   * content has access to the properties on the scope from which it was taken, even if the directive
+   * has isolated scope.
+   * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
+   *
+   * This makes it possible for the widget to have private state for its template, while the transcluded
+   * content has access to its originating scope.
+   *
+   * 

+   * **Note:** When testing an element transclude directive you must not place the directive at the root of the
+   * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
+   * Testing Transclusion Directives}.
+   * 

+   *
+   * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the
+   * directive's element, the entire element or multiple parts of the element contents:
+   *
+   * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
+   * * `'element'` - transclude the whole of the directive's element including any directives on this
+   *   element that defined at a lower priority than this directive. When used, the `template`
+   *   property is ignored.
+   * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template.
+   *
+   * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.
+   *
+   * This object is a map where the keys are the name of the slot to fill and the value is an element selector
+   * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)
+   * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).
+   *
+   * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}
+   *
+   * If the element selector is prefixed with a `?` then that slot is optional.
+   *
+   * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `` elements to
+   * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.
+   *
+   * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements
+   * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call
+   * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and
+   * injectable into the directive's controller.
+   *
+   *
+   * #### Transclusion Functions
+   *
+   * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
+   * function** to the directive's `link` function and `controller`. This transclusion function is a special
+   * **linking function** that will return the compiled contents linked to a new transclusion scope.
+   *
+   * 

+   * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
+   * ngTransclude will deal with it for us.
+   * 

+   *
+   * If you want to manually control the insertion and removal of the transcluded content in your directive
+   * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
+   * object that contains the compiled DOM, which is linked to the correct transclusion scope.
+   *
+   * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
+   * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
+   * content and the `scope` is the newly created transclusion scope, which the clone will be linked to.
+   *
+   * 

+   * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function
+   * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
+   * 

+   *
+   * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
+   * attach function**:
+   *
+   * ```js
+   * var transcludedContent, transclusionScope;
+   *
+   * $transclude(function(clone, scope) {
+   *   element.append(clone);
+   *   transcludedContent = clone;
+   *   transclusionScope = scope;
+   * });
+   * ```
+   *
+   * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
+   * associated transclusion scope:
+   *
+   * ```js
+   * transcludedContent.remove();
+   * transclusionScope.$destroy();
+   * ```
+   *
+   * 

+   * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
+   * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
+   * then you are also responsible for calling `$destroy` on the transclusion scope.
+   * 

+   *
+   * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
+   * automatically destroy their transcluded clones as necessary so you do not need to worry about this if
+   * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
+   *
+   *
+   * #### Transclusion Scopes
+   *
+   * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
+   * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
+   * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
+   * was taken.
+   *
+   * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
+   * like this:
+   *
+   * ```html
+   * 

+   *   

+   *     

+   *     

+   *   

+   * 

+   * ```
+   *
+   * The `$parent` scope hierarchy will look like this:
+   *
+     ```
+     - $rootScope
+       - isolate
+         - transclusion
+     ```
+   *
+   * but the scopes will inherit prototypically from different scopes to their `$parent`.
+   *
+     ```
+     - $rootScope
+       - transclusion
+     - isolate
+     ```
+   *
+   *
+   * ### Attributes
+   *
+   * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
+   * `link()` or `compile()` functions. It has a variety of uses.
+   *
+   * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:
+   *   'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access
+   *   to the attributes.
+   *
+   * * *Directive inter-communication:* All directives share the same instance of the attributes
+   *   object which allows the directives to use the attributes object as inter directive
+   *   communication.
+   *
+   * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
+   *   allowing other directives to read the interpolated value.
+   *
+   * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
+   *   that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
+   *   the only way to easily get the actual value because during the linking phase the interpolation
+   *   hasn't been evaluated yet and so the value is at this time set to `undefined`.
+   *
+   * ```js
+   * function linkingFn(scope, elm, attrs, ctrl) {
+   *   // get the attribute value
+   *   console.log(attrs.ngModel);
+   *
+   *   // change the attribute
+   *   attrs.$set('ngModel', 'new value');
+   *
+   *   // observe changes to interpolated attribute
+   *   attrs.$observe('ngModel', function(value) {
+   *     console.log('ngModel has changed value to ' + value);
+   *   });
+   * }
+   * ```
+   *
+   * ## Example
+   *
+   * 

+   * **Note**: Typically directives are registered with `module.directive`. The example below is
+   * to illustrate how `$compile` works.
+   * 

+   *
+   
+     
+      
+      

+         

+         

+        

+      

+     
+     
+       it('should auto compile', function() {
+         var textarea = $('textarea');
+         var output = $('div[compile]');
+         // The initial state reads 'Hello AngularJS'.
+         expect(output.getText()).toBe('Hello AngularJS');
+         textarea.clear();
+         textarea.sendKeys('{{name}}!');
+         expect(output.getText()).toBe('AngularJS!');
+       });
+     
+   
+  
+   *
+   *
+   * @param {string|DOMElement} element Element or HTML string to compile into a template function.
+   * @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives - DEPRECATED.
+   *
+   * 

+   * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it
+   *   e.g. will not use the right outer scope. Please pass the transclude function as a
+   *   `parentBoundTranscludeFn` to the link function instead.
+   * 

+   *
+   * @param {number} maxPriority only apply directives lower than given priority (Only effects the
+   *                 root element(s), not their children)
+   * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template
+   * (a DOM element/tree) to a scope. Where:
+   *
+   *  * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
+   *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
+   *  `template` and call the `cloneAttachFn` function allowing the caller to attach the
+   *  cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
+   *  called as: 
 `cloneAttachFn(clonedElement, scope)` where:
+   *
+   *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
+   *      * `scope` - is the current scope with which the linking function is working with.
+   *
+   *  * `options` - An optional object hash with linking options. If `options` is provided, then the following
+   *  keys may be used to control linking behavior:
+   *
+   *      * `parentBoundTranscludeFn` - the transclude function made available to
+   *        directives; if given, it will be passed through to the link functions of
+   *        directives found in `element` during compilation.
+   *      * `transcludeControllers` - an object hash with keys that map controller names
+   *        to a hash with the key `instance`, which maps to the controller instance;
+   *        if given, it will make the controllers available to directives on the compileNode:
+   *        ```
+   *        {
+   *          parent: {
+   *            instance: parentControllerInstance
+   *          }
+   *        }
+   *        ```
+   *      * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add
+   *        the cloned elements; only needed for transcludes that are allowed to contain non html
+   *        elements (e.g. SVG elements). See also the directive.controller property.
+   *
+   * Calling the linking function returns the element of the template. It is either the original
+   * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
+   *
+   * After linking the view is not updated until after a call to $digest which typically is done by
+   * AngularJS automatically.
+   *
+   * If you need access to the bound view, there are two ways to do it:
+   *
+   * - If you are not asking the linking function to clone the template, create the DOM element(s)
+   *   before you send them to the compiler and keep this reference around.
+   *   ```js
+   *     var element = $compile('
{{total}}
')(scope);
+   *   ```
+   *
+   * - if on the other hand, you need the element to be cloned, the view reference from the original
+   *   example would not point to the clone, but rather to the original template that was cloned. In
+   *   this case, you can access the clone via the cloneAttachFn:
+   *   ```js
+   *     var templateElement = angular.element('
{{total}}
'),
+   *         scope = ....;
+   *
+   *     var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
+   *       //attach the clone to DOM document at the right place
+   *     });
+   *
+   *     //now we have reference to the cloned DOM via `clonedElement`
+   *   ```
+   *
+   *

+   * {@link guide/compiler AngularJS HTML Compiler} section of the Developer Guide.

+   * ### Double Compilation
+   *
+     Double compilation occurs when an already compiled part of the DOM gets
+     compiled again. This is an undesired effect and can lead to misbehaving directives, performance issues,
+     and memory leaks. Refer to the Compiler Guide {@link guide/compiler#double-compilation-and-how-to-avoid-it
+     section on double compilation} for an in-depth explanation and ways to avoid it.
+  
+   * @knownIssue
+  
+     ### Issues with `replace: true`
+   *
+   * 

+   *   **Note**: {@link $compile#-replace- `replace: true`} is deprecated and not recommended to use,
+   *   mainly due to the issues listed here. It has been completely removed in the new Angular.
+   * 

+   *
+   * #### Attribute values are not merged
+   *
+   * When a `replace` directive encounters the same attribute on the original and the replace node,
+   * it will simply deduplicate the attribute and join the values with a space or with a `;` in case of
+   * the `style` attribute.
+   * ```html
+   * Original Node: 
+   * Replace Template: 
+   * Result: 
+   * ```
    *
-   * In complex applications it's possible that dependencies between `$onChanges` hooks and bindings will result
-   * in several iterations of calls to these hooks. However if an application needs more than the default 10
-   * iterations to stabilize then you should investigate what is causing the model to continuously change during
-   * the `$onChanges` hook execution.
+   * That means attributes that contain AngularJS expressions will not be merged correctly, e.g.
+   * {@link ngShow} or {@link ngClass} will cause a {@link $parse} error:
    *
-   * Increasing the TTL could have performance implications, so you should not change it without proper justification.
+   * ```html
+   * Original Node: 
+   * Replace Template: 
+   * Result: 
+   * ```
+   *
+   * See issue [#5695](https://github.com/angular/angular.js/issues/5695).
+   *
+   * #### Directives are not deduplicated before compilation
+   *
+   * When the original node and the replace template declare the same directive(s), they will be
+   * {@link guide/compiler#double-compilation-and-how-to-avoid-it compiled twice} because the compiler
+   * does not deduplicate them. In many cases, this is not noticable, but e.g. {@link ngModel} will
+   * attach `$formatters` and `$parsers` twice.
+   *
+   * See issue [#2573](https://github.com/angular/angular.js/issues/2573).
+   *
+   * #### `transclude: element` in the replace template root can have unexpected effects
+   *
+   * When the replace template has a directive at the root node that uses
+   * {@link $compile#-transclude- `transclude: element`}, e.g.
+   * {@link ngIf} or {@link ngRepeat}, the DOM structure or scope inheritance can be incorrect.
+   * See the following issues:
+   *
+   * - Incorrect scope on replaced element:
+   * [#9837](https://github.com/angular/angular.js/issues/9837)
+   * - Different DOM between `template` and `templateUrl`:
+   * [#10612](https://github.com/angular/angular.js/issues/14326)
    *
-   * @param {number} limit The number of `$onChanges` hook iterations.
-   * @returns {number|object} the current limit (or `this` if called as a setter for chaining)

    * @description
+   * The `ngProp` directive binds an expression to a DOM element property.
+   * `ngProp` allows writing to arbitrary properties by including
+   * the property name in the attribute, e.g. `ng-prop-value="'my value'"` binds 'my value' to
+   * the `value` property.
+   *
+   * Usually, it's not necessary to write to properties in AngularJS, as the built-in directives
+   * handle the most common use cases (instead of the above example, you would use {@link ngValue}).
+   *
+   * However, [custom elements](https://developer.mozilla.org/docs/Web/Web_Components/Using_custom_elements)
+   * often use custom properties to hold data, and `ngProp` can be used to provide input to these
+   * custom elements.
+   *
+   * ## Binding to camelCase properties
+   *
+   * Since HTML attributes are case-insensitive, camelCase properties like `innerHTML` must be escaped.
+   * AngularJS uses the underscore (_) in front of a character to indicate that it is uppercase, so
+   * `innerHTML`  must be written as `ng-prop-inner_h_t_m_l="expression"` (Note that this is just an
+   * example, and for binding HTML {@link ngBindHtml} should be used.
+   *
+   * ## Security
+   *
+   * Binding expressions to arbitrary properties poses a security risk, as  properties like `innerHTML`
+   * can insert potentially dangerous HTML into the application, e.g. script tags that execute
+   * malicious code.
+   * For this reason, `ngProp` applies Strict Contextual Escaping with the {@link ng.$sce $sce service}.
+   * This means vulnerable properties require their content to be "trusted", based on the
+   * context of the property. For example, the `innerHTML` is in the `HTML` context, and the
+   * `iframe.src` property is in the `RESOURCE_URL` context, which requires that values written to
+   * this property are trusted as a `RESOURCE_URL`.
+   *
+   * This can be set explicitly by calling $sce.trustAs(type, value) on the value that is
+   * trusted before passing it to the `ng-prop-*` directive. There are exist shorthand methods for
+   * each context type in the form of {@link ng.$sce#trustAsResourceUrl $sce.trustAsResourceUrl()} et al.
+   *
+   * In some cases you can also rely upon automatic sanitization of untrusted values - see below.
+   *
+   * Based on the context, other options may exist to mark a value as trusted / configure the behavior
+   * of {@link ng.$sce}. For example, to restrict the `RESOURCE_URL` context to specific origins, use
+   * the {@link $sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist()}
+   * and {@link $sceDelegateProvider#resourceUrlBlacklist resourceUrlBlacklist()}.
+   *
+   * {@link ng.$sce#what-trusted-context-types-are-supported- Find out more about the different context types}.
+   *
+   * ### HTML Sanitization
    *
-   * It indicates to the compiler
-   * whether or not directives on comments should be compiled.
-   * Defaults to `true`.
+   * By default, `$sce` will throw an error if it detects untrusted HTML content, and will not bind the
+   * content.
+   * However, if you include the {@link ngSanitize ngSanitize module}, it will try to sanitize the
+   * potentially dangerous HTML, e.g. strip non-whitelisted tags and attributes when binding to
+   * `innerHTML`.
    *
-   * Calling this function with false disables the compilation of directives
-   * on comments for the whole application.
-   * This results in a compilation performance gain,
-   * as the compiler doesn't have to check comments when looking for directives.
-   * This should however only be used if you are sure that no comment directives are used in
-   * the application (including any 3rd party directives).
+   * @example
+   * ### Binding to different contexts
+   *
+   * 
+   *   
+   *     angular.module('exampleNgProp', [])
+   *       .component('main', {
+   *         templateUrl: 'main.html',
+   *         controller: function($sce) {
+   *           this.safeContent = 'Safe content';
+   *           this.unsafeContent = '';
+   *           this.trustedUnsafeContent = $sce.trustAsHtml(this.unsafeContent);
+   *         }
+   *       });
+   *   
+   *   
+   *     

+   *       

+   *         Binding to a property without security context:
+   *         

+   *         innerText (safeContent)
+   *       

+   *
+   *       

+   *         "Safe" content that requires a security context will throw because the contents could potentially be dangerous ...
+   *         

+   *         innerHTML (safeContent)
+   *       

+   *
+   *       

+   *         ... so that actually dangerous content cannot be executed:
+   *         

+   *         innerHTML (unsafeContent)
+   *       

+   *
+   *       

+   *         ... but unsafe Content that has been trusted explicitly works - only do this if you are 100% sure!
+   *         

+   *         innerHTML (trustedUnsafeContent)
+   *       

+   *     

+   *   
+   *   
+   *     

+   *   
+   *   
+   *     .prop-unit {
+   *       margin-bottom: 10px;
+   *     }
+   *
+   *     .prop-binding {
+   *       min-height: 30px;
+   *       border: 1px solid blue;
+   *     }
+   *
+   *     .prop-note {
+   *       font-family: Monospace;
+   *     }
+   *   
+   * 
+   *
+   *
+   * @example
+   * ### Binding to innerHTML with ngSanitize
+   *
+   * 
+   *   
+   *     angular.module('exampleNgProp', ['ngSanitize'])
+   *       .component('main', {
+   *         templateUrl: 'main.html',
+   *         controller: function($sce) {
+   *           this.safeContent = 'Safe content';
+   *           this.unsafeContent = '';
+   *           this.trustedUnsafeContent = $sce.trustAsHtml(this.unsafeContent);
+   *         }
+   *       });
+   *   
+   *   
+   *     

+   *       

+   *         "Safe" content will be sanitized ...
+   *         

+   *         innerHTML (safeContent)
+   *       

+   *
+   *       

+   *         ... as will dangerous content:
+   *         

+   *         innerHTML (unsafeContent)
+   *       

+   *
+   *       

+   *         ... and content that has been trusted explicitly works the same as without ngSanitize:
+   *         

+   *         innerHTML (trustedUnsafeContent)
+   *       

+   *     

+   *   
+   *   
+   *     

+   *   
+   *   
+   *     .prop-unit {
+   *       margin-bottom: 10px;

    * @description
+   * The `ngOn` directive adds an event listener to a DOM element via
+   * {@link angular.element angular.element().on()}, and evaluates an expression when the event is
+   * fired.
+   * `ngOn` allows adding listeners for arbitrary events by including
+   * the event name in the attribute, e.g. `ng-on-drop="onDrop()"` executes the 'onDrop()' expression
+   * when the `drop` event is fired.
    *
-   * It indicates to the compiler
-   * whether or not directives on element classes should be compiled.
-   * Defaults to `true`.
+   * AngularJS provides specific directives for many events, such as {@link ngClick}, so in most
+   * cases it is not necessary to use `ngOn`. However, AngularJS does not support all events
+   * (e.g. the `drop` event in the example above), and new events might be introduced in later DOM
+   * standards.
    *
-   * Calling this function with false disables the compilation of directives
-   * on element classes for the whole application.
-   * This results in a compilation performance gain,
-   * as the compiler doesn't have to check element classes when looking for directives.
-   * This should however only be used if you are sure that no class directives are used in
-   * the application (including any 3rd party directives).
+   * Another use-case for `ngOn` is listening to
+   * [custom events](https://developer.mozilla.org/docs/Web/Guide/Events/Creating_and_triggering_events)
+   * fired by
+   * [custom elements](https://developer.mozilla.org/docs/Web/Web_Components/Using_custom_elements).
+   *
+   * ## Binding to camelCase properties
+   *
+   * Since HTML attributes are case-insensitive, camelCase properties like `myEvent` must be escaped.
+   * AngularJS uses the underscore (_) in front of a character to indicate that it is uppercase, so
+   * `myEvent` must be written as `ng-on-my_event="expression"`.
+   *
+   * @example
+   * ### Bind to built-in DOM events
+   *
+   * 
+   *   
+   *     angular.module('exampleNgOn', [])
+   *       .component('main', {
+   *         templateUrl: 'main.html',
+   *         controller: function() {
+   *           this.clickCount = 0;
+   *           this.mouseoverCount = 0;
+   *
+   *           this.loadingState = 0;
+   *         }
+   *       });
+   *   
+   *   
+   *     

+   *       This is equivalent to `ngClick` and `ngMouseover`:

+   *       

+   *       clickCount: {{$ctrl.clickCount}}

+   *       mouseover: {{$ctrl.mouseoverCount}}
+   *
+   *       

+   *
+   *       For the `error` and `load` event on images no built-in AngularJS directives exist:

+   *       

+   *       

+   *         Image is loading
+   *         Image load error
+   *         Image loaded successfully
+   *       

+   *     

+   *   
+   *   
+   *     

+   *   
+   * 
+   *
+   *
+   * @example
+   * ### Bind to custom DOM events
    *
-   * @param {boolean} enabled `false` if the compiler may ignore directives on element classes
-   * @returns {boolean|object} the current value (or `this` if called as a setter for chaining)
+   * 
+   *   
+   *     angular.module('exampleNgOn', [])
+   *       .component('main', {
+   *         templateUrl: 'main.html',
+   *         controller: function() {
+   *           this.eventLog = '';
+   *
+   *           this.listener = function($event) {
+   *             this.eventLog = 'Event with type "' + $event.type + '" fired at ' + $event.detail;
+   *           };
+   *         }
+   *       })
+   *       .component('childComponent', {
+   *         templateUrl: 'child.html',
+   *         controller: function($element) {
+   *           this.fireEvent = function() {
+   *             var event = new CustomEvent('customtype', { detail: new Date()});
+   *
+   *             $element[0].dispatchEvent(event);
+   *           };
+   *         }
+   *       });
+   *   
+   *   
+   *     

+   *     Event log: {{$ctrl.eventLog}}

+     * Register a **component definition** with the compiler. This is a shorthand for registering a special
+     * type of directive, which represents a self-contained UI component in your application. Such components
+     * are always isolated (i.e. `scope: {}`) and are always restricted to elements (i.e. `restrict: 'E'`).
+     *
+     * Component definitions are very simple and do not require as much configuration as defining general
+     * directives. Component definitions usually consist only of a template and a controller backing it.
+     *
+     * In order to make the definition easier, components enforce best practices like use of `controllerAs`,
+     * `bindToController`. They always have **isolate scope** and are restricted to elements.
+     *
+     * Here are a few examples of how you would usually define components:
+     *
+     * ```js
+     *   var myMod = angular.module(...);
+     *   myMod.component('myComp', {
+     *     template: '
My name is {{$ctrl.name}}
',
+     *     controller: function() {
+     *       this.name = 'shahar';
+     *     }
+     *   });
+     *
+     *   myMod.component('myComp', {
+     *     template: '
My name is {{$ctrl.name}}
',
+     *     bindings: {name: '@'}
+     *   });
+     *
+     *   myMod.component('myComp', {
+     *     templateUrl: 'views/my-comp.html',
+     *     controller: 'MyCtrl',
+     *     controllerAs: 'ctrl',
+     *     bindings: {name: '@'}
+     *   });
+     *

      * @description
-     * The `$http` service is a core AngularJS service that facilitates communication with the remote
-     * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
-     * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
-     *
-     * For unit testing applications that use `$http` service, see
-     * {@link ngMock.$httpBackend $httpBackend mock}.
-     *
-     * For a higher level of abstraction, please check out the {@link ngResource.$resource
-     * $resource} service.
-     *
-     * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
-     * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
-     * it is important to familiarize yourself with these APIs and the guarantees they provide.
-     *
-     *
-     * ## General usage
-     * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —
-     * that is used to generate an HTTP request and returns  a {@link ng.$q promise} that is
-     * resolved (request success) or rejected (request failure) with a
-     * {@link ng.$http#$http-returns response} object.
-     *
-     * ```js
-     *   // Simple GET request example:
-     *   $http({
-     *     method: 'GET',
-     *     url: '/someUrl'
-     *   }).then(function successCallback(response) {
-     *       // this callback will be called asynchronously
-     *       // when the response is available
-     *     }, function errorCallback(response) {
-     *       // called asynchronously if an error occurs
-     *       // or server returns response with an error status.
-     *     });
-     * ```
      *
+     * Object containing default values for all {@link ng.$http $http} requests.
      *
-     * ## Shortcut methods
+     * - **`defaults.cache`** - {boolean|Object} - A boolean value or object created with
+     * {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of HTTP responses
+     * by default. See {@link $http#caching $http Caching} for more information.
      *
-     * Shortcut methods are also available. All shortcut methods require passing in the URL, and
-     * request data must be passed in for POST/PUT requests. An optional config can be passed as the
-     * last argument.
+     * - **`defaults.headers`** - {Object} - Default headers for all $http requests.
+     * Refer to {@link ng.$http#setting-http-headers $http} for documentation on
+     * setting default headers.
+     *     - **`defaults.headers.common`**
+     *     - **`defaults.headers.post`**
+     *     - **`defaults.headers.put`**
+     *     - **`defaults.headers.patch`**
      *
-     * ```js
-     *   $http.get('/someUrl', config).then(successCallback, errorCallback);
-     *   $http.post('/someUrl', data, config).then(successCallback, errorCallback);
-     * ```
+     * - **`defaults.jsonpCallbackParam`** - `{string}` - the name of the query parameter that passes the name of the
+     * callback in a JSONP request. The value of this parameter will be replaced with the expression generated by the
+     * {@link $jsonpCallbacks} service. Defaults to `'callback'`.
      *
-     * Complete list of shortcut methods:
+     * - **`defaults.paramSerializer`** - `{string|function(Object):string}` - A function
+     *  used to the prepare string representation of request parameters (specified as an object).
+     *  If specified as string, it is interpreted as a function registered with the {@link auto.$injector $injector}.
+     *  Defaults to {@link ng.$httpParamSerializer $httpParamSerializer}.

+     * - **`defaults.transformRequest`** -

+     * An array of functions (or a single function) which are applied to the request data.
+     * By default, this is an array with one request transformation function:
      *
+     *   - If the `data` property of the request configuration object contains an object, serialize it
+     *     into JSON format.
      *
-     * ## Writing Unit Tests that use $http
-     * When unit testing (using {@link ngMock ngMock}), it is necessary to call
-     * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
-     * request using trained responses.
+     * - **`defaults.transformResponse`** -
+     * `{Array|function(data, headersGetter, status)}` -
+     * An array of functions (or a single function) which are applied to the response data. By default,
+     * this is an array which applies one response transformation function that does two things:
      *
-     * ```
-     * $httpBackend.expectGET(...);
-     * $http.get(...);
-     * $httpBackend.flush();
-     * ```
+     *  - If XSRF prefix is detected, strip it
+     *    (see {@link ng.$http#security-considerations Security Considerations in the $http docs}).
+     *  - If the `Content-Type` is `application/json` or the response looks like JSON,
+     *    deserialize it using a JSON parser.
      *
-     * ## Setting HTTP Headers
+     * - **`defaults.xsrfCookieName`** - {string} - Name of cookie containing the XSRF token.
+     * Defaults value is `'XSRF-TOKEN'`.
      *
-     * The $http service will automatically add certain HTTP headers to all requests. These defaults
-     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
-     * object, which currently contains this default configuration:
+     * - **`defaults.xsrfHeaderName`** - {string} - Name of HTTP header to populate with the
+     * XSRF token. Defaults value is `'X-XSRF-TOKEN'`.
      *
-     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):

-     * ## Transforming Requests and Responses
+     * Array containing URLs whose origins are trusted to receive the XSRF token. See the
+     * {@link ng.$http#security-considerations Security Considerations} sections for more details on
+     * XSRF.
      *
-     * Both requests and responses can be transformed using transformation functions: `transformRequest`
-     * and `transformResponse`. These properties can be a single function that returns
-     * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
-     * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
+     * **Note:** An "origin" consists of the [URI scheme](https://en.wikipedia.org/wiki/URI_scheme),
+     * the [hostname](https://en.wikipedia.org/wiki/Hostname) and the
+     * [port number](https://en.wikipedia.org/wiki/Port_(computer_networking). For `http:` and
+     * `https:`, the port number can be omitted if using th default ports (80 and 443 respectively).
+     * Examples: `http://example.com`, `https://api.example.com:9876`
      *
      * 

-     * **Note:** AngularJS does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.
-     * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).
-     * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest
-     * function will be reflected on the scope and in any templates where the object is data-bound.
-     * To prevent this, transform functions should have no side-effects.
-     * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.
+     *   It is not possible to whitelist specific URLs/paths. The `path`, `query` and `fragment` parts
+     *   of a URL will be ignored. For example, `https://foo.com/path/bar?query=baz#fragment` will be
+     *   treated as `https://foo.com`, meaning that **all** requests to URLs starting with
+     *   `https://foo.com/` will include the XSRF token.
      * 

      *
-     * ### Default Transformations
-     *
-     * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
-     * `defaults.transformResponse` properties. If a request does not provide its own transformations
-     * then these will be applied.
-     *
-     * You can augment or replace the default transformations by modifying these properties by adding to or
-     * replacing the array.
-     *
-     * AngularJS provides the following default transformations:
-     *
-     * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`) is
-     * an array with one function that does the following:
-     *
-     * - If the `data` property of the request configuration object contains an object, serialize it
-     *   into JSON format.
-     *
-     * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`) is
-     * an array with one function that does the following:
-     *
-     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
-     *  - If the `Content-Type` is `application/json` or the response looks like JSON,
-   *      deserialize it using a JSON parser.
-     *
-     *
-     * ### Overriding the Default Transformations Per Request
-     *
-     * If you wish to override the request/response transformations only for a single request then provide
-     * `transformRequest` and/or `transformResponse` properties on the configuration object passed
-     * into `$http`.
-     *
-     * Note that if you provide these properties on the config object the default transformations will be
-     * overwritten. If you wish to augment the default transformations then you must include them in your
-     * local transformation array.
-     *
-     * The following code demonstrates adding a new response transformation to be run after the default response
-     * transformations have been run.
-     *
-     * ```js
-     * function appendTransform(defaults, transform) {
-     *
-     *   // We can't guarantee that the default transformation is an array
-     *   defaults = angular.isArray(defaults) ? defaults : [defaults];
-     *
-     *   // Append the new transformation to the defaults
-     *   return defaults.concat(transform);
-     * }
-     *
-     * $http({
-     *   url: '...',
-     *   method: 'GET',
-     *   transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
-     *     return doTransform(value);
-     *   })
-     * });
-     * ```
-     *
-     *
-     * ## Caching
-     *
-     * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must
-     * set the config.cache value or the default cache value to TRUE or to a cache object (created
-     * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes
-     * precedence over the default cache value.
-     *
-     * In order to:
-     *   * cache all responses - set the default cache value to TRUE or to a cache object
-     *   * cache a specific response - set config.cache value to TRUE or to a cache object
-     *
-     * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,
-     * then the default `$cacheFactory("$http")` object is used.
-     *
-     * The default cache value can be set by updating the
-     * {@link ng.$http#defaults `$http.defaults.cache`} property or the
-     * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.
-     *
-     * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using
-     * the relevant cache object. The next time the same request is made, the response is returned
-     * from the cache without sending a request to the server.
-     *
-     * Take note that:
-     *
-     *   * Only GET and JSONP requests are cached.
-     *   * The cache key is the request URL including search parameters; headers are not considered.
-     *   * Cached responses are returned asynchronously, in the same way as responses from the server.
-     *   * If multiple identical requests are made using the same cache, which is not yet populated,
-     *     one request will be made to the server and remaining requests will return the same response.
-     *   * A cache-control header on the response does not affect if or how responses are cached.
-     *
-     *
-     * ## Interceptors
-     *
-     * Before you start creating interceptors, be sure to understand the
-     * {@link ng.$q $q and deferred/promise APIs}.
-     *
-     * For purposes of global error handling, authentication, or any kind of synchronous or
-     * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
-     * able to intercept requests before they are handed to the server and
-     * responses before they are handed over to the application code that
-     * initiated these requests. The interceptors leverage the {@link ng.$q
-     * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
-     *
-     * The interceptors are service factories that are registered with the `$httpProvider` by
-     * adding them to the `$httpProvider.interceptors` array. The factory is called and
-     * injected with dependencies (if specified) and returns the interceptor.
-     *
-     * There are two kinds of interceptors (and two kinds of rejection interceptors):
-     *
-     *   * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
-     *     modify the `config` object or create a new one. The function needs to return the `config`
-     *     object directly, or a promise containing the `config` or a new `config` object.
-     *   * `requestError`: interceptor gets called when a previous interceptor threw an error or
-     *     resolved with a rejection.
-     *   * `response`: interceptors get called with http `response` object. The function is free to
-     *     modify the `response` object or create a new one. The function needs to return the `response`
-     *     object directly, or as a promise containing the `response` or a new `response` object.
-     *   * `responseError`: interceptor gets called when a previous interceptor threw an error or
-     *     resolved with a rejection.
-     *
-     *
-     * ```js
-     *   // register the interceptor as a service
-     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
-     *     return {
-     *       // optional method
-     *       'request': function(config) {
-     *         // do something on success
-     *         return config;
-     *       },
-     *
-     *       // optional method
-     *      'requestError': function(rejection) {
-     *         // do something on error
-     *         if (canRecover(rejection)) {
-     *           return responseOrNewPromise
-     *         }
-     *         return $q.reject(rejection);
-     *       },
-     *
-     *
-     *
-     *       // optional method
-     *       'response': function(response) {
-     *         // do something on success
-     *         return response;
-     *       },
-     *
-     *       // optional method
-     *      'responseError': function(rejection) {
-     *         // do something on error
-     *         if (canRecover(rejection)) {
-     *           return responseOrNewPromise
-     *         }
-     *         return $q.reject(rejection);
-     *       }
-     *     };
-     *   });
-     *
-     *   $httpProvider.interceptors.push('myHttpInterceptor');
-     *
-     *
-     *   // alternatively, register the interceptor via an anonymous factory
-     *   $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
-     *     return {
-     *      'request': function(config) {
-     *          // same as above
-     *       },
-     *
-     *       'response': function(response) {
-     *          // same as above
-     *       }
-     *     };
-     *   });
-     * ```
-     *
-     * ## Security Considerations
-     *
-     * When designing web applications, consider security threats from:
-     *
-     * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
-     * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
-     *
-     * Both server and the client must cooperate in order to eliminate these threats. AngularJS comes
-     * pre-configured with strategies that address these issues, but for this to work backend server
-     * cooperation is required.
-     *
-     * ### JSON Vulnerability Protection
-     *
-     * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
-     * allows third party website to turn your JSON resource URL into
-     * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
-     * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
-     * AngularJS will automatically strip the prefix before processing it as JSON.
+     * @example
      *
-     * For example if your server needs to return:
      * ```js
-     * ['one','two']
-     * ```
+     * // App served from `https://example.com/`.
+     * angular.
+     *   module('xsrfWhitelistedOriginsExample', []).
+     *   config(['$httpProvider', function($httpProvider) {
+     *     $httpProvider.xsrfWhitelistedOrigins.push('https://api.example.com');
+     *   }]).
+     *   run(['$http', function($http) {
+     *     // The XSRF token will be sent.
+     *     $http.get('https://api.example.com/preferences').then(...);
      *
-     * which is vulnerable to attack, your server can return:
-     * ```js
-     * )]}',
-     * ['one','two']
+     *     // The XSRF token will NOT be sent.
+     *     $http.get('https://stats.example.com/activity').then(...);
+     *   }]);
      * ```
-     *
-     * AngularJS will strip the prefix, before processing the JSON.
-     *
-     *
-     * ### Cross Site Request Forgery (XSRF) Protection
-     *
-     * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by
-     * which the attacker can trick an authenticated user into unknowingly executing actions on your
-     * website. AngularJS provides a mechanism to counter XSRF. When performing XHR requests, the
-     * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP
-     * header (by default `X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read
-     * the cookie, your server can be assured that the XHR came from JavaScript running on your
-     * domain.
-     *
-     * To take advantage of this, your server needs to set a token in a JavaScript readable session
-     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
-     * server can verify that the cookie matches the `X-XSRF-TOKEN` HTTP header, and therefore be
-     * sure that only JavaScript running on your domain could have sent the request. The token must
-     * be unique for each user and must be verifiable by the server (to prevent the JavaScript from
-     * making up its own tokens). We recommend that the token is a digest of your site's
-     * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))
-     * for added security.
-     *
-     * The header will — by default — **not** be set for cross-domain requests. This
-     * prevents unauthorized servers (e.g. malicious or compromised 3rd-party APIs) from gaining
-     * access to your users' XSRF tokens and exposing them to Cross Site Request Forgery. If you
-     * want to, you can whitelist additional origins to also receive the XSRF token, by adding them
-     * to {@link ng.$httpProvider#xsrfWhitelistedOrigins xsrfWhitelistedOrigins}. This might be
-     * useful, for example, if your application, served from `example.com`, needs to access your API
-     * at `api.example.com`.
-     * See {@link ng.$httpProvider#xsrfWhitelistedOrigins $httpProvider.xsrfWhitelistedOrigins} for
-     * more details.
-     *
-     * 

-     *   **Warning**

-     *   Only whitelist origins that you have control over and make sure you understand the
-     *   implications of doing so.
-     * 

-     *
-     * The name of the cookie and the header can be specified using the `xsrfCookieName` and
-     * `xsrfHeaderName` properties of either `$httpProvider.defaults` at config-time,
-     * `$http.defaults` at run-time, or the per-request config object.
-     *
-     * In order to prevent collisions in environments where multiple AngularJS apps share the
-     * same domain or subdomain, we recommend that each application uses a unique cookie name.
-     *
-     *
-     * @param {object} config Object describing the request to be made and how it should be
-     *    processed. The object has following properties:
-     *
-     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
-     *    - **url** – `{string|TrustedObject}` – Absolute or relative URL of the resource that is being requested;
-     *      or an object created by a call to `$sce.trustAsResourceUrl(url)`.
-     *    - **params** – `{Object.}` – Map of strings or objects which will be serialized
-     *      with the `paramSerializer` and appended as GET parameters.
-     *    - **data** – `{string|Object}` – Data to be sent as the request message data.
-     *    - **headers** – `{Object}` – Map of strings or functions which return strings representing
-     *      HTTP headers to send to the server. If the return value of a function is null, the
-     *      header will not be sent. Functions accept a config object as an argument.
-     *    - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.
-     *      To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.
-     *      The handler will be called in the context of a `$apply` block.
-     *    - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload
-     *      object. To bind events to the XMLHttpRequest object, use `eventHandlers`.
-     *      The handler will be called in the context of a `$apply` block.
-     *    - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
-     *    - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
-     *    - **transformRequest** –
-     *      `{function(data, headersGetter)|Array.}` –
-     *      transform function or an array of such functions. The transform function takes the http
-     *      request body and headers and returns its transformed (typically serialized) version.
-     *      See {@link ng.$http#overriding-the-default-transformations-per-request
-     *      Overriding the Default Transformations}
-     *    - **transformResponse** –
-     *      `{function(data, headersGetter, status)|Array.}` –
-     *      transform function or an array of such functions. The transform function takes the http
-     *      response body, headers and status and returns its transformed (typically deserialized) version.
-     *      See {@link ng.$http#overriding-the-default-transformations-per-request
-     *      Overriding the Default Transformations}
-     *    - **paramSerializer** - `{string|function(Object):string}` - A function used to
-     *      prepare the string representation of request parameters (specified as an object).
-     *      If specified as string, it is interpreted as function registered with the
-     *      {@link $injector $injector}, which means you can create your own serializer
-     *      by registering it as a {@link auto.$provide#service service}.
-     *      The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
-     *      alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
-     *    - **cache** – `{boolean|Object}` – A boolean value or object created with
-     *      {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
-     *      See {@link $http#caching $http Caching} for more information.
-     *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
-     *      that should abort the request when resolved.
-     *
-     *      A numerical timeout or a promise returned from {@link ng.$timeout $timeout}, will set
-     *      the `xhrStatus` in the {@link $http#$http-returns response} to "timeout", and any other
-     *      resolved promise will set it to "abort", following standard XMLHttpRequest behavior.
-     *
-     *    - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
-     *      XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
-     *      for more information.
-     *    - **responseType** - `{string}` - see
-     *      [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
-     *
-     * @returns {HttpPromise} A {@link ng.$q `Promise}` that will be resolved (request success)
-     *   or rejected (request failure) with a response object.
-     *
-     *   The response object has these properties:
-     *
-     *   - **data** – `{string|Object}` – The response body transformed with
-     *     the transform functions.
-     *   - **status** – `{number}` – HTTP status code of the response.
-     *   - **headers** – `{function([headerName])}` – Header getter function.
-     *   - **config** – `{Object}` – The configuration object that was used
-     *     to generate the request.
-     *   - **statusText** – `{string}` – HTTP status text of the response.
-     *   - **xhrStatus** – `{string}` – Status of the XMLHttpRequest
-     *     (`complete`, `error`, `timeout` or `abort`).
-     *
-     *
-     *   A response status code between 200 and 299 is considered a success status
-     *   and will result in the success callback being called. Any response status
-     *   code outside of that range is considered an error status and will result
-     *   in the error callback being called.
-     *   Also, status codes less than -1 are normalized to zero. -1 usually means
-     *   the request was aborted, e.g. using a `config.timeout`. More information
-     *   about the status might be available in the `xhrStatus` property.
-     *
-     *   Note that if the response is a redirect, XMLHttpRequest will transparently
-     *   follow it, meaning that the outcome (success or error) will be determined
-     *   by the final response status code.
-     *
-     *
-     * @property {Array.} pendingRequests Array of config objects for currently pending
-     *   requests. This is primarily meant to be used for debugging purposes.

+       * @description
+       * The `$http` service is a core AngularJS service that facilitates communication with the remote
+       * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
+       * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
+       *
+       * For unit testing applications that use `$http` service, see
+       * {@link ngMock.$httpBackend $httpBackend mock}.
+       *
+       * For a higher level of abstraction, please check out the {@link ngResource.$resource
+       * $resource} service.
+       *
+       * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
+       * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
+       * it is important to familiarize yourself with these APIs and the guarantees they provide.
+       *
+       *
+       * ## General usage
+       * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —
+       * that is used to generate an HTTP request and returns  a {@link ng.$q promise} that is
+       * resolved (request success) or rejected (request failure) with a
+       * {@link ng.$http#$http-returns response} object.
+       *
+       * ```js
+       *   // Simple GET request example:
+       *   $http({
+       *     method: 'GET',
+       *     url: '/someUrl'
+       *   }).then(function successCallback(response) {
+       *       // this callback will be called asynchronously
+       *       // when the response is available
+       *     }, function errorCallback(response) {
+       *       // called asynchronously if an error occurs
+       *       // or server returns response with an error status.
+       *     });
+       * ```
+       *
+       *
+       * ## Shortcut methods
+       *
+       * Shortcut methods are also available. All shortcut methods require passing in the URL, and
+       * request data must be passed in for POST/PUT requests. An optional config can be passed as the
+       * last argument.
+       *
+       * ```js
+       *   $http.get('/someUrl', config).then(successCallback, errorCallback);
+       *   $http.post('/someUrl', data, config).then(successCallback, errorCallback);
+       * ```
+       *
+       * Complete list of shortcut methods:
+       *
+       * - {@link ng.$http#get $http.get}
+       * - {@link ng.$http#head $http.head}
+       * - {@link ng.$http#post $http.post}
+       * - {@link ng.$http#put $http.put}
+       * - {@link ng.$http#delete $http.delete}
+       * - {@link ng.$http#jsonp $http.jsonp}
+       * - {@link ng.$http#patch $http.patch}
+       *
+       *
+       * ## Writing Unit Tests that use $http
+       * When unit testing (using {@link ngMock ngMock}), it is necessary to call
+       * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
+       * request using trained responses.
+       *
+       * ```
+       * $httpBackend.expectGET(...);
+       * $http.get(...);
+       * $httpBackend.flush();
+       * ```
+       *
+       * ## Setting HTTP Headers
+       *
+       * The $http service will automatically add certain HTTP headers to all requests. These defaults
+       * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
+       * object, which currently contains this default configuration:
+       *
+       * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
+       *   - Accept: application/json, text/plain, \*/\*
+       * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
+       *   - `Content-Type: application/json`
+       * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
+       *   - `Content-Type: application/json`
+       *
+       * To add or overwrite these defaults, simply add or remove a property from these configuration
+       * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
+       * with the lowercased HTTP method name as the key, e.g.
+       * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
+       *
+       * The defaults can also be set at runtime via the `$http.defaults` object in the same
+       * fashion. For example:
+       *
+       * ```
+       * module.run(function($http) {
+       *   $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';
+       * });
+       * ```
+       *
+       * In addition, you can supply a `headers` property in the config object passed when
+       * calling `$http(config)`, which overrides the defaults without changing them globally.
+       *
+       * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
+       * Use the `headers` property, setting the desired header to `undefined`. For example:
+       *
+       * ```js
+       * var req = {
+       *  method: 'POST',
+       *  url: 'http://example.com',
+       *  headers: {
+       *    'Content-Type': undefined
+       *  },
+       *  data: { test: 'test' }
+       * }
+       *
+       * $http(req).then(function(){...}, function(){...});
+       * ```
+       *
+       * ## Transforming Requests and Responses
+       *
+       * Both requests and responses can be transformed using transformation functions: `transformRequest`
+       * and `transformResponse`. These properties can be a single function that returns
+       * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
+       * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
+       *
+       * 

+       * **Note:** AngularJS does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.
+       * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).
+       * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest
+       * function will be reflected on the scope and in any templates where the object is data-bound.
+       * To prevent this, transform functions should have no side-effects.
+       * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.
+       * 

+       *
+       * ### Default Transformations
+       *
+       * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
+       * `defaults.transformResponse` properties. If a request does not provide its own transformations
+       * then these will be applied.
+       *
+       * You can augment or replace the default transformations by modifying these properties by adding to or
+       * replacing the array.
+       *
+       * AngularJS provides the following default transformations:
+       *
+       * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`) is
+       * an array with one function that does the following:
+       *
+       * - If the `data` property of the request configuration object contains an object, serialize it
+       *   into JSON format.
+       *
+       * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`) is
+       * an array with one function that does the following:
+       *
+       *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
+       *  - If the `Content-Type` is `application/json` or the response looks like JSON,
+      *      deserialize it using a JSON parser.
+       *
+       *
+       * ### Overriding the Default Transformations Per Request
+       *
+       * If you wish to override the request/response transformations only for a single request then provide
+       * `transformRequest` and/or `transformResponse` properties on the configuration object passed
+       * into `$http`.
+       *
+       * Note that if you provide these properties on the config object the default transformations will be
+       * overwritten. If you wish to augment the default transformations then you must include them in your
+       * local transformation array.
+       *
+       * The following code demonstrates adding a new response transformation to be run after the default response
+       * transformations have been run.
+       *
+       * ```js
+       * function appendTransform(defaults, transform) {
+       *
+       *   // We can't guarantee that the default transformation is an array
+       *   defaults = angular.isArray(defaults) ? defaults : [defaults];
+       *
+       *   // Append the new transformation to the defaults
+       *   return defaults.concat(transform);
+       * }
+       *
+       * $http({
+       *   url: '...',
+       *   method: 'GET',
+       *   transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
+       *     return doTransform(value);
+       *   })
+       * });
+       * ```
+       *
+       *
+       * ## Caching
+       *
+       * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must
+       * set the config.cache value or the default cache value to TRUE or to a cache object (created
+       * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes
+       * precedence over the default cache value.
+       *
+       * In order to:
+       *   * cache all responses - set the default cache value to TRUE or to a cache object
+       *   * cache a specific response - set config.cache value to TRUE or to a cache object
+       *
+       * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,
+       * then the default `$cacheFactory("$http")` object is used.
+       *
+       * The default cache value can be set by updating the
+       * {@link ng.$http#defaults `$http.defaults.cache`} property or the
+       * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.
+       *
+       * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using
+       * the relevant cache object. The next time the same request is made, the response is returned
+       * from the cache without sending a request to the server.
+       *
+       * Take note that:
+       *
+       *   * Only GET and JSONP requests are cached.
+       *   * The cache key is the request URL including search parameters; headers are not considered.
+       *   * Cached responses are returned asynchronously, in the same way as responses from the server.
+       *   * If multiple identical requests are made using the same cache, which is not yet populated,
+       *     one request will be made to the server and remaining requests will return the same response.
+       *   * A cache-control header on the response does not affect if or how responses are cached.
+       *
+       *
+       * ## Interceptors
+       *
+       * Before you start creating interceptors, be sure to understand the
+       * {@link ng.$q $q and deferred/promise APIs}.
+       *
+       * For purposes of global error handling, authentication, or any kind of synchronous or
+       * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
+       * able to intercept requests before they are handed to the server and
+       * responses before they are handed over to the application code that
+       * initiated these requests. The interceptors leverage the {@link ng.$q
+       * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
+       *
+       * The interceptors are service factories that are registered with the `$httpProvider` by
+       * adding them to the `$httpProvider.interceptors` array. The factory is called and
+       * injected with dependencies (if specified) and returns the interceptor.
+       *
+       * There are two kinds of interceptors (and two kinds of rejection interceptors):
+       *
+       *   * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
+       *     modify the `config` object or create a new one. The function needs to return the `config`
+       *     object directly, or a promise containing the `config` or a new `config` object.
+       *   * `requestError`: interceptor gets called when a previous interceptor threw an error or
+       *     resolved with a rejection.
+       *   * `response`: interceptors get called with http `response` object. The function is free to
+       *     modify the `response` object or create a new one. The function needs to return the `response`
+       *     object directly, or as a promise containing the `response` or a new `response` object.
+       *   * `responseError`: interceptor gets called when a previous interceptor threw an error or
+       *     resolved with a rejection.
+       *
+       *
+       * ```js
+       *   // register the interceptor as a service
+       *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
+       *     return {
+       *       // optional method
+       *       'request': function(config) {
+       *         // do something on success
+       *         return config;
+       *       },
+       *
+       *       // optional method
+       *      'requestError': function(rejection) {
+       *         // do something on error
+       *         if (canRecover(rejection)) {
+       *           return responseOrNewPromise
+       *         }
+       *         return $q.reject(rejection);
+       *       },
+       *
+       *
+       *
+       *       // optional method
+       *       'response': function(response) {
+       *         // do something on success
+       *         return response;
+       *       },
+       *
+       *       // optional method
+       *      'responseError': function(rejection) {
+       *         // do something on error
+       *         if (canRecover(rejection)) {
+       *           return responseOrNewPromise
+       *         }
+       *         return $q.reject(rejection);
+       *       }
+       *     };
+       *   });
+       *
+       *   $httpProvider.interceptors.push('myHttpInterceptor');
+       *
+       *
+       *   // alternatively, register the interceptor via an anonymous factory
+       *   $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
+       *     return {
+       *      'request': function(config) {
+       *          // same as above
+       *       },
+       *
+       *       'response': function(response) {
+       *          // same as above
+       *       }
+       *     };
+       *   });
+       * ```
+       *
+       * ## Security Considerations
+       *
+       * When designing web applications, consider security threats from:
+       *
+       * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
+       * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
+       *
+       * Both server and the client must cooperate in order to eliminate these threats. AngularJS comes
+       * pre-configured with strategies that address these issues, but for this to work backend server
+       * cooperation is required.
+       *
+       * ### JSON Vulnerability Protection
+       *
+       * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
+       * allows third party website to turn your JSON resource URL into
+       * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
+       * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
+       * AngularJS will automatically strip the prefix before processing it as JSON.
+       *
+       * For example if your server needs to return:
+       * ```js
+       * ['one','two']
+       * ```
+       *
+       * which is vulnerable to attack, your server can return:
+       * ```js
+       * )]}',
+       * ['one','two']
+       * ```
+       *
+       * AngularJS will strip the prefix, before processing the JSON.
+       *
+       *
+       * ### Cross Site Request Forgery (XSRF) Protection
+       *
+       * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by
+       * which the attacker can trick an authenticated user into unknowingly executing actions on your
+       * website. AngularJS provides a mechanism to counter XSRF. When performing XHR requests, the
+       * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP
+       * header (by default `X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read
+       * the cookie, your server can be assured that the XHR came from JavaScript running on your
+       * domain.
+       *
+       * To take advantage of this, your server needs to set a token in a JavaScript readable session
+       * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
+       * server can verify that the cookie matches the `X-XSRF-TOKEN` HTTP header, and therefore be
+       * sure that only JavaScript running on your domain could have sent the request. The token must
+       * be unique for each user and must be verifiable by the server (to prevent the JavaScript from
+       * making up its own tokens). We recommend that the token is a digest of your site's
+       * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))
+       * for added security.
+       *
+       * The header will — by default — **not** be set for cross-domain requests. This
+       * prevents unauthorized servers (e.g. malicious or compromised 3rd-party APIs) from gaining
+       * access to your users' XSRF tokens and exposing them to Cross Site Request Forgery. If you
+       * want to, you can whitelist additional origins to also receive the XSRF token, by adding them
+       * to {@link ng.$httpProvider#xsrfWhitelistedOrigins xsrfWhitelistedOrigins}. This might be
+       * useful, for example, if your application, served from `example.com`, needs to access your API
+       * at `api.example.com`.
+       * See {@link ng.$httpProvider#xsrfWhitelistedOrigins $httpProvider.xsrfWhitelistedOrigins} for
+       * more details.
+       *
+       * 

+       *   **Warning**

+       *   Only whitelist origins that you have control over and make sure you understand the
+       *   implications of doing so.
+       * 

+       *
+       * The name of the cookie and the header can be specified using the `xsrfCookieName` and
+       * `xsrfHeaderName` properties of either `$httpProvider.defaults` at config-time,
+       * `$http.defaults` at run-time, or the per-request config object.
+       *
+       * In order to prevent collisions in environments where multiple AngularJS apps share the
+       * same domain or subdomain, we recommend that each application uses a unique cookie name.
+       *
+       *
+       * @param {object} config Object describing the request to be made and how it should be
+       *    processed. The object has following properties:
+       *
+       *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
+       *    - **url** – `{string|TrustedObject}` – Absolute or relative URL of the resource that is being requested;
+       *      or an object created by a call to `$sce.trustAsResourceUrl(url)`.
+       *    - **params** – `{Object.}` – Map of strings or objects which will be serialized
+       *      with the `paramSerializer` and appended as GET parameters.
+       *    - **data** – `{string|Object}` – Data to be sent as the request message data.
+       *    - **headers** – `{Object}` – Map of strings or functions which return strings representing
+       *      HTTP headers to send to the server. If the return value of a function is null, the
+       *      header will not be sent. Functions accept a config object as an argument.
+       *    - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.
+       *      To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.
+       *      The handler will be called in the context of a `$apply` block.
+       *    - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload
+       *      object. To bind events to the XMLHttpRequest object, use `eventHandlers`.
+       *      The handler will be called in the context of a `$apply` block.
+       *    - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
+       *    - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
+       *    - **transformRequest** –
+       *      `{function(data, headersGetter)|Array.}` –
+       *      transform function or an array of such functions. The transform function takes the http
+       *      request body and headers and returns its transformed (typically serialized) version.
+       *      See {@link ng.$http#overriding-the-default-transformations-per-request
+       *      Overriding the Default Transformations}
+       *    - **transformResponse** –
+       *      `{function(data, headersGetter, status)|Array.}` –
+       *      transform function or an array of such functions. The transform function takes the http
+       *      response body, headers and status and returns its transformed (typically deserialized) version.
+       *      See {@link ng.$http#overriding-the-default-transformations-per-request
+       *      Overriding the Default Transformations}
+       *    - **paramSerializer** - `{string|function(Object):string}` - A function used to
+       *      prepare the string representation of request parameters (specified as an object).
+       *      If specified as string, it is interpreted as function registered with the
+       *      {@link $injector $injector}, which means you can create your own serializer
+       *      by registering it as a {@link auto.$provide#service service}.
+       *      The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
+       *      alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
+       *    - **cache** – `{boolean|Object}` – A boolean value or object created with
+       *      {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
+       *      See {@link $http#caching $http Caching} for more information.
+       *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
+       *      that should abort the request when resolved.
+       *
+       *      A numerical timeout or a promise returned from {@link ng.$timeout $timeout}, will set
+       *      the `xhrStatus` in the {@link $http#$http-returns response} to "timeout", and any other
+       *      resolved promise will set it to "abort", following standard XMLHttpRequest behavior.
+       *
+       *    - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
+       *      XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
+       *      for more information.
+       *    - **responseType** - `{string}` - see
+       *      [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
+       *
+       * @returns {HttpPromise} A {@link ng.$q `Promise}` that will be resolved (request success)
+       *   or rejected (request failure) with a response object.
+       *
+       *   The response object has these properties:
+       *
+       *   - **data** – `{string|Object}` – The response body transformed with
+       *     the transform functions.
+       *   - **status** – `{number}` – HTTP status code of the response.
+       *   - **headers** – `{function([headerName])}` – Header getter function.
+       *   - **config** – `{Object}` – The configuration object that was used
+       *     to generate the request.
+       *   - **statusText** – `{string}` – HTTP status text of the response.
+       *   - **xhrStatus** – `{string}` – Status of the XMLHttpRequest
+       *     (`complete`, `error`, `timeout` or `abort`).
+       *
+       *
+       *   A response status code between 200 and 299 is considered a success status
+       *   and will result in the success callback being called. Any response status
+       *   code outside of that range is considered an error status and will result
+       *   in the error callback being called.
+       *   Also, status codes less than -1 are normalized to zero. -1 usually means
+       *   the request was aborted, e.g. using a `config.timeout`. More information
+       *   about the status might be available in the `xhrStatus` property.
+       *
+       *   Note that if the response is a redirect, XMLHttpRequest will transparently
+       *   follow it, meaning that the outcome (success or error) will be determined
+       *   by the final response status code.
+       *
+       *
+       * @property {Array.} pendingRequests Array of config objects for currently pending
+       *   requests. This is primarily meant to be used for debugging purposes.
+       *

-     * Shortcut method to perform `JSONP` request.
-     *
-     * Note that, since JSONP requests are sensitive because the response is given full access to the browser,
-     * the url must be declared, via {@link $sce} as a trusted resource URL.
-     * You can trust a URL by adding it to the whitelist via
-     * {@link $sceDelegateProvider#resourceUrlWhitelist  `$sceDelegateProvider.resourceUrlWhitelist`} or
-     * by explicitly trusting the URL via {@link $sce#trustAsResourceUrl `$sce.trustAsResourceUrl(url)`}.
-     *
-     * You should avoid generating the URL for the JSONP request from user provided data.
-     * Provide additional query parameters via `params` property of the `config` parameter, rather than
-     * modifying the URL itself.
-     *
-     * JSONP requests must specify a callback to be used in the response from the server. This callback
-     * is passed as a query parameter in the request. You must specify the name of this parameter by
-     * setting the `jsonpCallbackParam` property on the request config object.
-     *
-     * ```
-     * $http.jsonp('some/trusted/url', {jsonpCallbackParam: 'callback'})
-     * ```
-     *
-     * You can also specify a default callback parameter name in `$http.defaults.jsonpCallbackParam`.
-     * Initially this is set to `'callback'`.
-     *
-     * 

-     * You can no longer use the `JSON_CALLBACK` string as a placeholder for specifying where the callback
-     * parameter value should go.
-     * 

-     *
-     * If you would like to customise where and how the callbacks are stored then try overriding
-     * or decorating the {@link $jsonpCallbacks} service.

+       *
+       * Note that, since JSONP requests are sensitive because the response is given full access to the browser,
+       * the url must be declared, via {@link $sce} as a trusted resource URL.
+       * You can trust a URL by adding it to the whitelist via
+       * {@link $sceDelegateProvider#resourceUrlWhitelist  `$sceDelegateProvider.resourceUrlWhitelist`} or
+       * by explicitly trusting the URL via {@link $sce#trustAsResourceUrl `$sce.trustAsResourceUrl(url)`}.
+       *
+       * You should avoid generating the URL for the JSONP request from user provided data.
+       * Provide additional query parameters via `params` property of the `config` parameter, rather than
+       * modifying the URL itself.
+       *
+       * JSONP requests must specify a callback to be used in the response from the server. This callback
+       * is passed as a query parameter in the request. You must specify the name of this parameter by
+       * setting the `jsonpCallbackParam` property on the request config object.
+       *
+       * ```
+       * $http.jsonp('some/trusted/url', {jsonpCallbackParam: 'callback'})
+       * ```
+       *
+       * You can also specify a default callback parameter name in `$http.defaults.jsonpCallbackParam`.
+       * Initially this is set to `'callback'`.
+       *
+       * 

+       * You can no longer use the `JSON_CALLBACK` string as a placeholder for specifying where the callback
+       * parameter value should go.
+       * 

+       *
+       * If you would like to customise where and how the callbacks are stored then try overriding
+       * or decorating the {@link $jsonpCallbacks} service.

-     *
-     * @description
-     *
-     * Compiles a string with markup into an interpolation function. This service is used by the
-     * HTML {@link ng.$compile $compile} service for data binding. See
-     * {@link ng.$interpolateProvider $interpolateProvider} for configuring the
-     * interpolation markup.
-     *
-     *
-     * ```js
-     *   var $interpolate = ...; // injected
-     *   var exp = $interpolate('Hello {{name | uppercase}}!');
-     *   expect(exp({name:'AngularJS'})).toEqual('Hello ANGULARJS!');
-     * ```
-     *
-     * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
-     * `true`, the interpolation function will return `undefined` unless all embedded expressions
-     * evaluate to a value other than `undefined`.
-     *
-     * ```js
-     *   var $interpolate = ...; // injected
-     *   var context = {greeting: 'Hello', name: undefined };
-     *
-     *   // default "forgiving" mode
-     *   var exp = $interpolate('{{greeting}} {{name}}!');
-     *   expect(exp(context)).toEqual('Hello !');
-     *
-     *   // "allOrNothing" mode
-     *   exp = $interpolate('{{greeting}} {{name}}!', false, null, true);
-     *   expect(exp(context)).toBeUndefined();
-     *   context.name = 'AngularJS';
-     *   expect(exp(context)).toEqual('Hello AngularJS!');
-     * ```
-     *
-     * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
-     *
-     * #### Escaped Interpolation
-     * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
-     * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
-     * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
-     * or binding.
-     *
-     * This enables web-servers to prevent script injection attacks and defacing attacks, to some
-     * degree, while also enabling code examples to work without relying on the
-     * {@link ng.directive:ngNonBindable ngNonBindable} directive.
-     *
-     * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
-     * replacing angle brackets (<, >) with &lt; and &gt; respectively, and replacing all
-     * interpolation start/end markers with their escaped counterparts.**
-     *
-     * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
-     * output when the $interpolate service processes the text. So, for HTML elements interpolated
-     * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
-     * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
-     * this is typically useful only when user-data is used in rendering a template from the server, or
-     * when otherwise untrusted data is used by a directive.
-     *
-     * 
-     *  
-     *    

-     *      
{{apptitle}}: \{\{ username = "defaced value"; \}\}
-     *        

-     *      
{{username}} attempts to inject code which will deface the
-     *        application, but fails to accomplish their task, because the server has correctly
-     *        escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
-     *        characters.

-     *      
Instead, the result of the attempted script injection is visible, and can be removed
-     *        from the database by an administrator.

-     *    

-     *  
-     * 
-     *
-     * @knownIssue
-     * It is currently not possible for an interpolated expression to contain the interpolation end
-     * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e.
-     * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string.
-     *
-     * @knownIssue
-     * All directives and components must use the standard `{{` `}}` interpolation symbols
-     * in their templates. If you change the application interpolation symbols the {@link $compile}
-     * service will attempt to denormalize the standard symbols to the custom symbols.
-     * The denormalization process is not clever enough to know not to replace instances of the standard
-     * symbols where they would not normally be treated as interpolation symbols. For example in the following
-     * code snippet the closing braces of the literal object will get incorrectly denormalized:
-     *
-     * ```
-     * 

-     * ```

      * @description
-     * AngularJS's wrapper for `window.setInterval`. The `fn` function is executed every `delay`
-     * milliseconds.
-     *
-     * The return value of registering an interval function is a promise. This promise will be
-     * notified upon each tick of the interval, and will be resolved after `count` iterations, or
-     * run indefinitely if `count` is not defined. The value of the notification will be the
-     * number of iterations that have run.
-     * To cancel an interval, call `$interval.cancel(promise)`.
-     *
-     * In tests you can use {@link ngMock.$interval#flush `$interval.flush(millis)`} to
-     * move forward by `millis` milliseconds and trigger any functions scheduled to run in that
-     * time.
-     *
-     * 

-     * **Note**: Intervals created by this service must be explicitly destroyed when you are finished
-     * with them.  In particular they are not automatically destroyed when a controller's scope or a
-     * directive's element are destroyed.
-     * You should take this into consideration and make sure to always cancel the interval at the
-     * appropriate moment.  See the example below for more details on how and when to do this.
-     * 

-     *
-     * @param {function()} fn A function that should be called repeatedly. If no additional arguments
-     *   are passed (see below), the function is called with the current iteration count.
-     * @param {number} delay Number of milliseconds between each function call.
-     * @param {number=} [count=0] Number of times to repeat. If not set, or 0, will repeat
-     *   indefinitely.
-     * @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise
-     *   will invoke `fn` within the {@link ng.$rootScope.Scope#$apply $apply} block.
-     * @param {...*=} Pass additional parameters to the executed function.
-     * @returns {promise} A promise which will be notified on each iteration. It will resolve once all iterations of the interval complete.
-     *
-     * @example
-     * 
-     * 
-     *   
-     *
-     *

+       * ```
+       *
+       * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
+       *
+       * #### Escaped Interpolation
+       * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
+       * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
+       * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
+       * or binding.
+       *
+       * This enables web-servers to prevent script injection attacks and defacing attacks, to some
+       * degree, while also enabling code examples to work without relying on the
+       * {@link ng.directive:ngNonBindable ngNonBindable} directive.
+       *
+       * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
+       * replacing angle brackets (<, >) with &lt; and &gt; respectively, and replacing all
+       * interpolation start/end markers with their escaped counterparts.**
+       *
+       * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
+       * output when the $interpolate service processes the text. So, for HTML elements interpolated
+       * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
+       * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
+       * this is typically useful only when user-data is used in rendering a template from the server, or
+       * when otherwise untrusted data is used by a directive.
+       *
+       * 
+       *  
+       *    

+       *      
{{apptitle}}: \{\{ username = "defaced value"; \}\}
+       *        

+       *      
{{username}} attempts to inject code which will deface the
+       *        application, but fails to accomplish their task, because the server has correctly
+       *        escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
+       *        characters.

+       *      
Instead, the result of the attempted script injection is visible, and can be removed
+       *        from the database by an administrator.

+       *    

+       *  
+       * 
+       *
+       * @knownIssue
+       * It is currently not possible for an interpolated expression to contain the interpolation end
+       * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e.
+       * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string.
+       *
+       * @knownIssue
+       * All directives and components must use the standard `{{` `}}` interpolation symbols
+       * in their templates. If you change the application interpolation symbols the {@link $compile}
+       * service will attempt to denormalize the standard symbols to the custom symbols.
+       * The denormalization process is not clever enough to know not to replace instances of the standard
+       * symbols where they would not normally be treated as interpolation symbols. For example in the following
+       * code snippet the closing braces of the literal object will get incorrectly denormalized:
+       *
+       * ```
+       * 

+       * ```

+       * milliseconds.
+       *
+       * The return value of registering an interval function is a promise. This promise will be
+       * notified upon each tick of the interval, and will be resolved after `count` iterations, or
+       * run indefinitely if `count` is not defined. The value of the notification will be the

+       * **Note**: Intervals created by this service must be explicitly destroyed when you are finished

+       * directive's element are destroyed.
+       * You should take this into consideration and make sure to always cancel the interval at the
+       * appropriate moment.  See the example below for more details on how and when to do this.

+       *
+       * @param {function()} fn A function that should be called repeatedly. If no additional arguments
+       *   are passed (see below), the function is called with the current iteration count.
+       * @param {number} delay Number of milliseconds between each function call.
+       * @param {number=} [count=0] Number of times to repeat. If not set, or 0, will repeat
+       *   indefinitely.
+       * @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise
+       *   will invoke `fn` within the {@link ng.$rootScope.Scope#$apply $apply} block.
+       * @param {...*=} Pass additional parameters to the executed function.
+       * @returns {promise} A promise which will be notified on each iteration. It will resolve once all iterations of the interval complete.
+       *

-   *
-   * Return search part (as object) of current URL when called without any parameter.
-   *
-   * Change search part when called with parameter and return `$location`.
-   *
-   *
-   * ```js
-   * // given URL http://example.com/#/some/path?foo=bar&baz=xoxo
-   * var searchObject = $location.search();
-   * // => {foo: 'bar', baz: 'xoxo'}
-   *
-   * // set foo to 'yipee'
-   * $location.search('foo', 'yipee');
-   * // $location.search() => {foo: 'yipee', baz: 'xoxo'}
-   * ```
-   *
-   * @param {string|Object.|Object.>} search New search params - string or
-   * hash object.
-   *
-   * When called with a single argument the method acts as a setter, setting the `search` component
-   * of `$location` to the specified value.
-   *
-   * If the argument is a hash object containing an array of values, these values will be encoded
-   * as duplicate search parameters in the URL.
-   *
-   * @param {(string|Number|Array|boolean)=} paramValue If `search` is a string or number, then `paramValue`
-   * will override only a single search property.
-   *
-   * If `paramValue` is an array, it will override the property of the `search` component of
-   * `$location` specified via the first argument.
-   *
-   * If `paramValue` is `null`, the property specified via the first argument will be deleted.
-   *
-   * If `paramValue` is `true`, the property specified via the first argument will be added with no
-   * value nor trailing equal sign.
-   *
-   * @return {Object} If called with no arguments returns the parsed `search` object. If called with
-   * one or more arguments returns `$location` object itself.
+   * Use the `$locationProvider` to configure how the application deep linking paths are stored.

+   *
    * @description
-   * Broadcasted before a URL will change.
+   * Simple service for logging. Default implementation safely writes the message
+   * into the browser's console (if present).
    *
-   * This change can be prevented by calling
-   * `preventDefault` method of the event. See {@link ng.$rootScope.Scope#$on} for more
-   * details about event object. Upon successful change
-   * {@link ng.$location#$locationChangeSuccess $locationChangeSuccess} is fired.
+   * The main purpose of this service is to simplify debugging and troubleshooting.
    *
-   * The `newState` and `oldState` parameters may be defined only in HTML5 mode and when
-   * the browser supports the HTML5 History API.
+   * To reveal the location of the calls to `$log` in the JavaScript console,
+   * you can "blackbox" the AngularJS source in your browser:
    *
-   * @param {Object} angularEvent Synthetic event object.
-   * @param {string} newUrl New URL
-   * @param {string=} oldUrl URL that was before it was changed.
-   * @param {string=} newState New history state object
-   * @param {string=} oldState History state object that was before it was changed.
+   * [Mozilla description of blackboxing](https://developer.mozilla.org/en-US/docs/Tools/Debugger/How_to/Black_box_a_source).
+   * [Chrome description of blackboxing](https://developer.chrome.com/devtools/docs/blackboxing).
+   *
+   * Note: Not all browsers support blackboxing.
+   *
+   * The default is to log `debug` messages. You can use
+   * {@link ng.$logProvider ng.$logProvider#debugEnabled} to change this.
+   *
+   * @example
+     
+       
+         angular.module('logExample', [])
+           .controller('LogController', ['$scope', '$log', function($scope, $log) {
+             $scope.$log = $log;
+             $scope.message = 'Hello World!';
+           }]);
+       
+       
+

- * @ngdoc service
- * @name $log
- * @requires $window
- *
- * @description
- * Simple service for logging. Default implementation safely writes the message
- * into the browser's console (if present).
- *
- * The main purpose of this service is to simplify debugging and troubleshooting.
- *
- * To reveal the location of the calls to `$log` in the JavaScript console,
- * you can "blackbox" the AngularJS source in your browser:
- *
- * [Mozilla description of blackboxing](https://developer.mozilla.org/en-US/docs/Tools/Debugger/How_to/Black_box_a_source).
- * [Chrome description of blackboxing](https://developer.chrome.com/devtools/docs/blackboxing).
- *
- * Note: Not all browsers support blackboxing.
- *
- * The default is to log `debug` messages. You can use
- * {@link ng.$logProvider ng.$logProvider#debugEnabled} to change this.
- *
- * @example
-   
-     
-       angular.module('logExample', [])
-         .controller('LogController', ['$scope', '$log', function($scope, $log) {
-           $scope.$log = $log;
-           $scope.message = 'Hello World!';
-         }]);
-     
-     
-       

-

-/**
- * @ngdoc service
- * @name $q
- * @requires $rootScope
- *
- * @description
- * A service that helps you run functions asynchronously, and use their return values (or exceptions)
- * when they are done processing.
- *
- * This is a [Promises/A+](https://promisesaplus.com/)-compliant implementation of promises/deferred
- * objects inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
- *
- * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
- * implementations, and the other which resembles ES6 (ES2015) promises to some degree.
- *
- * ## $q constructor
- *
- * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
- * function as the first argument. This is similar to the native Promise implementation from ES6,
- * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
- *
- * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are
- * available yet.
- *
- * It can be used like so:
- *
- * ```js
- *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
- *   // are available in the current lexical scope (they could have been injected or passed in).
- *
- *   function asyncGreet(name) {
- *     // perform some asynchronous operation, resolve or reject the promise when appropriate.
- *     return $q(function(resolve, reject) {
- *       setTimeout(function() {
- *         if (okToGreet(name)) {
- *           resolve('Hello, ' + name + '!');
- *         } else {
- *           reject('Greeting ' + name + ' is not allowed.');
- *         }
- *       }, 1000);
- *     });
- *   }
- *
- *   var promise = asyncGreet('Robin Hood');
- *   promise.then(function(greeting) {
- *     alert('Success: ' + greeting);
- *   }, function(reason) {
- *     alert('Failed: ' + reason);
- *   });
- * ```
- *
- * Note: progress/notify callbacks are not currently supported via the ES6-style interface.
- *
- * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise.
- *
- * However, the more traditional CommonJS-style usage is still available, and documented below.
- *
- * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
- * interface for interacting with an object that represents the result of an action that is
- * performed asynchronously, and may or may not be finished at any given point in time.
- *
- * From the perspective of dealing with error handling, deferred and promise APIs are to
- * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
- *
- * ```js
- *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
- *   // are available in the current lexical scope (they could have been injected or passed in).
- *
- *   function asyncGreet(name) {
- *     var deferred = $q.defer();
- *
- *     setTimeout(function() {
- *       deferred.notify('About to greet ' + name + '.');
- *
- *       if (okToGreet(name)) {
- *         deferred.resolve('Hello, ' + name + '!');
- *       } else {
- *         deferred.reject('Greeting ' + name + ' is not allowed.');
- *       }
- *     }, 1000);
- *
- *     return deferred.promise;
- *   }
- *
- *   var promise = asyncGreet('Robin Hood');
- *   promise.then(function(greeting) {
- *     alert('Success: ' + greeting);
- *   }, function(reason) {
- *     alert('Failed: ' + reason);
- *   }, function(update) {
- *     alert('Got notification: ' + update);
- *   });
- * ```
- *
- * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
- * comes in the way of guarantees that promise and deferred APIs make, see
- * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
- *
- * Additionally the promise api allows for composition that is very hard to do with the
- * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
- * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
- * section on serial or parallel joining of promises.
- *
- * ## The Deferred API
- *
- * A new instance of deferred is constructed by calling `$q.defer()`.
- *
- * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
- * that can be used for signaling the successful or unsuccessful completion, as well as the status
- * of the task.
- *
- * **Methods**
- *
- * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
- *   constructed via `$q.reject`, the promise will be rejected instead.
- * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
- *   resolving it with a rejection constructed via `$q.reject`.
- * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
- *   multiple times before the promise is either resolved or rejected.
- *
- * **Properties**
- *
- * - promise – `{Promise}` – promise object associated with this deferred.
- *
- *
- * ## The Promise API
- *
- * A new promise instance is created when a deferred instance is created and can be retrieved by
- * calling `deferred.promise`.
- *
- * The purpose of the promise object is to allow for interested parties to get access to the result
- * of the deferred task when it completes.
- *
- * **Methods**
- *
- * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or
- *   will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
- *   as soon as the result is available. The callbacks are called with a single argument: the result
- *   or rejection reason. Additionally, the notify callback may be called zero or more times to
- *   provide a progress indication, before the promise is resolved or rejected.
- *
- *   This method *returns a new promise* which is resolved or rejected via the return value of the
- *   `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved
- *   with the value which is resolved in that promise using
- *   [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
- *   It also notifies via the return value of the `notifyCallback` method. The promise cannot be
- *   resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback
- *   arguments are optional.
- *
- * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
- *
- * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
- *   but to do so without modifying the final value. This is useful to release resources or do some
- *   clean-up that needs to be done whether the promise was rejected or resolved. See the [full
- *   specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
- *   more information.
- *
- * ## Chaining promises
- *
- * Because calling the `then` method of a promise returns a new derived promise, it is easily
- * possible to create a chain of promises:
- *
- * ```js
- *   promiseB = promiseA.then(function(result) {
- *     return result + 1;
- *   });
- *
- *   // promiseB will be resolved immediately after promiseA is resolved and its value
- *   // will be the result of promiseA incremented by 1
- * ```
- *
- * It is possible to create chains of any length and since a promise can be resolved with another
- * promise (which will defer its resolution further), it is possible to pause/defer resolution of
- * the promises at any point in the chain. This makes it possible to implement powerful APIs like
- * $http's response interceptors.
- *
- *
- * ## Differences between Kris Kowal's Q and $q
- *
- *  There are two main differences:
- *
- * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
- *   mechanism in AngularJS, which means faster propagation of resolution or rejection into your
- *   models and avoiding unnecessary browser repaints, which would result in flickering UI.
- * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
- *   all the important functionality needed for common async tasks.
- *
- * ## Testing
- *
- *  ```js
- *    it('should simulate promise', inject(function($q, $rootScope) {
- *      var deferred = $q.defer();
- *      var promise = deferred.promise;
- *      var resolvedValue;
- *
- *      promise.then(function(value) { resolvedValue = value; });
- *      expect(resolvedValue).toBeUndefined();
- *
- *      // Simulate resolving of promise
- *      deferred.resolve(123);
- *      // Note that the 'then' function does not get called synchronously.
- *      // This is because we want the promise API to always be async, whether or not
- *      // it got called synchronously or asynchronously.
- *      expect(resolvedValue).toBeUndefined();
- *
- *      // Propagate promise resolution to 'then' functions using $apply().
- *      $rootScope.$apply();
- *      expect(resolvedValue).toEqual(123);

-   * Retrieves or overrides whether to generate an error when a rejected promise is not handled.
-   * This feature is enabled by default.
+   * A service that helps you run functions asynchronously, and use their return values (or exceptions)
+   * when they are done processing.
+   *
+   * This is a [Promises/A+](https://promisesaplus.com/)-compliant implementation of promises/deferred
+   * objects inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
+   *
+   * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
+   * implementations, and the other which resembles ES6 (ES2015) promises to some degree.
+   *
+   * ## $q constructor
+   *
+   * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
+   * function as the first argument. This is similar to the native Promise implementation from ES6,
+   * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
+   *
+   * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are
+   * available yet.
+   *
+   * It can be used like so:
+   *
+   * ```js
+   *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
+   *   // are available in the current lexical scope (they could have been injected or passed in).
+   *
+   *   function asyncGreet(name) {
+   *     // perform some asynchronous operation, resolve or reject the promise when appropriate.
+   *     return $q(function(resolve, reject) {
+   *       setTimeout(function() {
+   *         if (okToGreet(name)) {
+   *           resolve('Hello, ' + name + '!');
+   *         } else {
+   *           reject('Greeting ' + name + ' is not allowed.');
+   *         }
+   *       }, 1000);
+   *     });
+   *   }
+   *
+   *   var promise = asyncGreet('Robin Hood');
+   *   promise.then(function(greeting) {
+   *     alert('Success: ' + greeting);
+   *   }, function(reason) {
+   *     alert('Failed: ' + reason);
+   *   });
+   * ```
+   *
+   * Note: progress/notify callbacks are not currently supported via the ES6-style interface.
+   *
+   * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise.
+   *
+   * However, the more traditional CommonJS-style usage is still available, and documented below.
+   *
+   * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
+   * interface for interacting with an object that represents the result of an action that is
+   * performed asynchronously, and may or may not be finished at any given point in time.
+   *
+   * From the perspective of dealing with error handling, deferred and promise APIs are to
+   * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
+   *
+   * ```js
+   *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
+   *   // are available in the current lexical scope (they could have been injected or passed in).
+   *
+   *   function asyncGreet(name) {
+   *     var deferred = $q.defer();
+   *
+   *     setTimeout(function() {
+   *       deferred.notify('About to greet ' + name + '.');
+   *
+   *       if (okToGreet(name)) {
+   *         deferred.resolve('Hello, ' + name + '!');
+   *       } else {
+   *         deferred.reject('Greeting ' + name + ' is not allowed.');
+   *       }
+   *     }, 1000);
+   *
+   *     return deferred.promise;
+   *   }
+   *
+   *   var promise = asyncGreet('Robin Hood');
+   *   promise.then(function(greeting) {
+   *     alert('Success: ' + greeting);
+   *   }, function(reason) {
+   *     alert('Failed: ' + reason);
+   *   }, function(update) {
+   *     alert('Got notification: ' + update);
+   *   });
+   * ```
+   *
+   * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
+   * comes in the way of guarantees that promise and deferred APIs make, see
+   * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
+   *
+   * Additionally the promise api allows for composition that is very hard to do with the
+   * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
+   * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
+   * section on serial or parallel joining of promises.
+   *
+   * ## The Deferred API
+   *
+   * A new instance of deferred is constructed by calling `$q.defer()`.
+   *
+   * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
+   * that can be used for signaling the successful or unsuccessful completion, as well as the status
+   * of the task.
+   *
+   * **Methods**
+   *
+   * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
+   *   constructed via `$q.reject`, the promise will be rejected instead.
+   * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
+   *   resolving it with a rejection constructed via `$q.reject`.
+   * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
+   *   multiple times before the promise is either resolved or rejected.
+   *
+   * **Properties**
+   *
+   * - promise – `{Promise}` – promise object associated with this deferred.
+   *
+   *
+   * ## The Promise API
+   *
+   * A new promise instance is created when a deferred instance is created and can be retrieved by
+   * calling `deferred.promise`.
+   *
+   * The purpose of the promise object is to allow for interested parties to get access to the result
+   * of the deferred task when it completes.
+   *
+   * **Methods**
+   *
+   * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or
+   *   will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
+   *   as soon as the result is available. The callbacks are called with a single argument: the result
+   *   or rejection reason. Additionally, the notify callback may be called zero or more times to
+   *   provide a progress indication, before the promise is resolved or rejected.
+   *
+   *   This method *returns a new promise* which is resolved or rejected via the return value of the
+   *   `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved
+   *   with the value which is resolved in that promise using
+   *   [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
+   *   It also notifies via the return value of the `notifyCallback` method. The promise cannot be
+   *   resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback
+   *   arguments are optional.
+   *
+   * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
+   *
+   * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
+   *   but to do so without modifying the final value. This is useful to release resources or do some
+   *   clean-up that needs to be done whether the promise was rejected or resolved. See the [full
+   *   specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
+   *   more information.
+   *
+   * ## Chaining promises
+   *
+   * Because calling the `then` method of a promise returns a new derived promise, it is easily
+   * possible to create a chain of promises:
+   *
+   * ```js
+   *   promiseB = promiseA.then(function(result) {
+   *     return result + 1;
+   *   });
+   *
+   *   // promiseB will be resolved immediately after promiseA is resolved and its value
+   *   // will be the result of promiseA incremented by 1
+   * ```
+   *
+   * It is possible to create chains of any length and since a promise can be resolved with another
+   * promise (which will defer its resolution further), it is possible to pause/defer resolution of
+   * the promises at any point in the chain. This makes it possible to implement powerful APIs like
+   * $http's response interceptors.
+   *
+   *
+   * ## Differences between Kris Kowal's Q and $q
+   *
+   *  There are two main differences:
+   *
+   * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
+   *   mechanism in AngularJS, which means faster propagation of resolution or rejection into your
+   *   models and avoiding unnecessary browser repaints, which would result in flickering UI.
+   * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
+   *   all the important functionality needed for common async tasks.
    *
-   * @param {boolean=} value Whether to generate an error when a rejected promise is not handled.
-   * @returns {boolean|ng.$qProvider} Current value when called without a new value or self for
-   *    chaining otherwise.
+   * ## Testing
+   *
+   *  ```js
+   *    it('should simulate promise', inject(function($q, $rootScope) {
+   *      var deferred = $q.defer();
+   *      var promise = deferred.promise;
+   *      var resolvedValue;
+   *
+   *      promise.then(function(value) { resolvedValue = value; });
+   *      expect(resolvedValue).toBeUndefined();
+   *
+   *      // Simulate resolving of promise
+   *      deferred.resolve(123);
+   *      // Note that the 'then' function does not get called synchronously.
+   *      // This is because we want the promise API to always be async, whether or not
+   *      // it got called synchronously or asynchronously.
+   *      expect(resolvedValue).toBeUndefined();
+   *
+   *      // Propagate promise resolution to 'then' functions using $apply().
+   *      $rootScope.$apply();
+   *      expect(resolvedValue).toEqual(123);
+   *    }));
+   *  ```
+   *
+   * @param {function(function, function)} resolver Function which is responsible for resolving or
+   *   rejecting the newly created promise. The first parameter is a function which resolves the
+   *   promise, the second parameter is a function which rejects the promise.
+   *
+   * @returns {Promise} The newly created promise.

        * @description
-       * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
-       *
-       * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
-       *   $digest()} and should return the value that will be watched. (`watchExpression` should not change
-       *   its value when executed multiple times with the same input because it may be executed multiple
-       *   times by {@link ng.$rootScope.Scope#$digest $digest()}. That is, `watchExpression` should be
-       *   [idempotent](http://en.wikipedia.org/wiki/Idempotence).)
-       * - The `listener` is called only when the value from the current `watchExpression` and the
-       *   previous call to `watchExpression` are not equal (with the exception of the initial run,
-       *   see below). Inequality is determined according to reference inequality,
-       *   [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
-       *    via the `!==` Javascript operator, unless `objectEquality == true`
-       *   (see next point)
-       * - When `objectEquality == true`, inequality of the `watchExpression` is determined
-       *   according to the {@link angular.equals} function. To save the value of the object for
-       *   later comparison, the {@link angular.copy} function is used. This therefore means that
-       *   watching complex objects will have adverse memory and performance implications.
-       * - This should not be used to watch for changes in objects that are (or contain)
-       *   [File](https://developer.mozilla.org/docs/Web/API/File) objects due to limitations with {@link angular.copy `angular.copy`}.
-       * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
-       *   This is achieved by rerunning the watchers until no changes are detected. The rerun
-       *   iteration limit is 10 to prevent an infinite loop deadlock.
-       *
-       *
-       * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
-       * you can register a `watchExpression` function with no `listener`. (Be prepared for
-       * multiple calls to your `watchExpression` because it will execute multiple times in a
-       * single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.)
-       *
-       * After a watcher is registered with the scope, the `listener` fn is called asynchronously
-       * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
-       * watcher. In rare cases, this is undesirable because the listener is called when the result
-       * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
-       * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
-       * listener was called due to initialization.
-       *
-       *
-       *
-       * @example
-       * ```js
-           // let's assume that scope was dependency injected as the $rootScope
-           var scope = $rootScope;
-           scope.name = 'misko';
-           scope.counter = 0;
-

+         *
+         * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
+         *   $digest()} and should return the value that will be watched. (`watchExpression` should not change
+         *   its value when executed multiple times with the same input because it may be executed multiple
+         *   times by {@link ng.$rootScope.Scope#$digest $digest()}. That is, `watchExpression` should be
+         *   [idempotent](http://en.wikipedia.org/wiki/Idempotence).)
+         * - The `listener` is called only when the value from the current `watchExpression` and the
+         *   previous call to `watchExpression` are not equal (with the exception of the initial run,
+         *   see below). Inequality is determined according to reference inequality,
+         *   [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
+         *    via the `!==` Javascript operator, unless `objectEquality == true`
+         *   (see next point)
+         * - When `objectEquality == true`, inequality of the `watchExpression` is determined
+         *   according to the {@link angular.equals} function. To save the value of the object for
+         *   later comparison, the {@link angular.copy} function is used. This therefore means that
+         *   watching complex objects will have adverse memory and performance implications.
+         * - This should not be used to watch for changes in objects that are (or contain)
+         *   [File](https://developer.mozilla.org/docs/Web/API/File) objects due to limitations with {@link angular.copy `angular.copy`}.
+         * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
+         *   This is achieved by rerunning the watchers until no changes are detected. The rerun
+         *   iteration limit is 10 to prevent an infinite loop deadlock.
+         *
+         *
+         * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
+         * you can register a `watchExpression` function with no `listener`. (Be prepared for
+         * multiple calls to your `watchExpression` because it will execute multiple times in a
+         * single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.)
+         *
+         * After a watcher is registered with the scope, the `listener` fn is called asynchronously
+         * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
+         * watcher. In rare cases, this is undesirable because the listener is called when the result
+         * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
+         * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
+         * listener was called due to initialization.
+         *
+         *
+         *
+         * @example
+         * ```js

-       * @description
-       * Processes all of the {@link ng.$rootScope.Scope#$watch watchers} of the current scope and
-       * its children. Because a {@link ng.$rootScope.Scope#$watch watcher}'s listener can change
-       * the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#$watch watchers}
-       * until no more listeners are firing. This means that it is possible to get into an infinite
-       * loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of
-       * iterations exceeds 10.
-       *
-       * Usually, you don't call `$digest()` directly in
-       * {@link ng.directive:ngController controllers} or in
-       * {@link ng.$compileProvider#directive directives}.
-       * Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within
-       * a {@link ng.$compileProvider#directive directive}), which will force a `$digest()`.
-       *
-       * If you want to be notified whenever `$digest()` is called,
-       * you can register a `watchExpression` function with
-       * {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`.
-       *
-       * In unit tests, you may need to call `$digest()` to simulate the scope life cycle.

-       * @example
-       * ```js

- * 

- *
- * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of

- *
- * @description
- *
- * The `$sceDelegateProvider` provider allows developers to configure the {@link ng.$sceDelegate
- * $sceDelegate service}, used as a delegate for {@link ng.$sce Strict Contextual Escaping (SCE)}.
- *
- * The `$sceDelegateProvider` allows one to get/set the whitelists and blacklists used to ensure
- * that the URLs used for sourcing AngularJS templates and other script-running URLs are safe (all
- * places that use the `$sce.RESOURCE_URL` context). See
- * {@link ng.$sceDelegateProvider#resourceUrlWhitelist $sceDelegateProvider.resourceUrlWhitelist}
- * and
- * {@link ng.$sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider.resourceUrlBlacklist},
- *
- * For the general details about this service in AngularJS, read the main page for {@link ng.$sce
- * Strict Contextual Escaping (SCE)}.
- *
- * **Example**:  Consider the following case. 
- *
- * - your app is hosted at url `http://myapp.example.com/`
- * - but some of your templates are hosted on other domains you control such as
- *   `http://srv01.assets.example.com/`, `http://srv02.assets.example.com/`, etc.
- * - and you have an open redirect at `http://myapp.example.com/clickThru?...`.
- *
- * Here is what a secure configuration for this scenario might look like:
- *
- * ```
- *  angular.module('myApp', []).config(function($sceDelegateProvider) {
- *    $sceDelegateProvider.resourceUrlWhitelist([
- *      // Allow same origin resource loads.
- *      'self',
- *      // Allow loading from our assets domain.  Notice the difference between * and **.
- *      'http://srv*.assets.example.com/**'
- *    ]);
- *
- *    // The blacklist overrides the whitelist so the open redirect here is blocked.
- *    $sceDelegateProvider.resourceUrlBlacklist([
- *      'http://myapp.example.com/clickThru**'
- *    ]);
- *  });
- * ```
- * Note that an empty whitelist will block every resource URL from being loaded, and will require
- * you to manually mark each one as trusted with `$sce.trustAsResourceUrl`. However, templates
- * requested by {@link ng.$templateRequest $templateRequest} that are present in
- * {@link ng.$templateCache $templateCache} will not go through this check. If you have a mechanism
- * to populate your templates in that cache at config time, then it is a good idea to remove 'self'
- * from that whitelist. This helps to mitigate the security impact of certain types of issues, like
- * for instance attacker-controlled `ng-includes`.

- * @ngdoc service
- * @name $sce
- * @kind function
- *
- * @description
- *
- * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
- *
- * ## Strict Contextual Escaping
- *
- * Strict Contextual Escaping (SCE) is a mode in which AngularJS constrains bindings to only render
- * trusted values. Its goal is to assist in writing code in a way that (a) is secure by default, and
- * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
- *
- * ### Overview
- *
- * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in
- * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically
- * run security checks on them (sanitizations, whitelists, depending on context), or throw when it
- * cannot guarantee the security of the result. That behavior depends strongly on contexts: HTML
- * can be sanitized, but template URLs cannot, for instance.
- *
- * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML:
- * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it
- * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and
- * render the input as-is, you will need to mark it as trusted for that context before attempting
- * to bind it.
- *
- * As of version 1.2, AngularJS ships with SCE enabled by default.
- *
- * ### In practice
- *
- * Here's an example of a binding in a privileged context:
- *
- * ```
- * 
- * 

- * ```
- *
- * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user.  With SCE
- * disabled, this application allows the user to render arbitrary HTML into the DIV, which would
- * be an XSS security bug. In a more realistic example, one may be rendering user comments, blog
- * articles, etc. via bindings. (HTML is just one example of a context where rendering user
- * controlled input creates security vulnerabilities.)
- *
- * For the case of HTML, you might use a library, either on the client side, or on the server side,
- * to sanitize unsafe HTML before binding to the value and rendering it in the document.
- *
- * How would you ensure that every place that used these types of bindings was bound to a value that
- * was sanitized by your library (or returned as safe for rendering by your server?)  How can you
- * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
- * properties/fields and forgot to update the binding to the sanitized value?
- *
- * To be secure by default, AngularJS makes sure bindings go through that sanitization, or
- * any similar validation process, unless there's a good reason to trust the given value in this
- * context.  That trust is formalized with a function call. This means that as a developer, you
- * can assume all untrusted bindings are safe. Then, to audit your code for binding security issues,
- * you just need to ensure the values you mark as trusted indeed are safe - because they were
- * received from your server, sanitized by your library, etc. You can organize your codebase to
- * help with this - perhaps allowing only the files in a specific directory to do this.
- * Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then
- * becomes a more manageable task.
- *
- * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
- * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
- * build the trusted versions of your values.
- *
- * ### How does it work?
- *
- * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
- * $sce.getTrusted(context, value)} rather than to the value directly.  Think of this function as
- * a way to enforce the required security context in your data sink. Directives use {@link
- * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs
- * the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also,
- * when binding without directives, AngularJS will understand the context of your bindings
- * automatically.
- *
- * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
- * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}.  Here's the actual code (slightly
- * simplified):
- *
- * ```
- * var ngBindHtmlDirective = ['$sce', function($sce) {
- *   return function(scope, element, attr) {
- *     scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
- *       element.html(value || '');
- *     });
- *   };
- * }];
- * ```
- *
- * ### Impact on loading templates
- *
- * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
- * `templateUrl`'s specified by {@link guide/directive directives}.
- *
- * By default, AngularJS only loads templates from the same domain and protocol as the application
- * document.  This is done by calling {@link ng.$sce#getTrustedResourceUrl
- * $sce.getTrustedResourceUrl} on the template URL.  To load templates from other domains and/or
- * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
- * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
- *
- * *Please note*:
- * The browser's
- * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
- * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
- * policy apply in addition to this and may further restrict whether the template is successfully
- * loaded.  This means that without the right CORS policy, loading templates from a different domain
- * won't work on all browsers.  Also, loading templates from `file://` URL does not work on some
- * browsers.
- *
- * ### This feels like too much overhead
- *
- * It's important to remember that SCE only applies to interpolation expressions.
- *
- * If your expressions are constant literals, they're automatically trusted and you don't need to
- * call `$sce.trustAs` on them (e.g.
- * `
`) just works (remember to include the
- * `ngSanitize` module). The `$sceDelegate` will also use the `$sanitize` service if it is available
- * when binding untrusted values to `$sce.HTML` context.
- * AngularJS provides an implementation in `angular-sanitize.js`, and if you
- * wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in
- * your application.
- *
- * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
- * templates in `ng-include` from your application's domain without having to even know about SCE.
- * It blocks loading templates from other domains or loading templates over http from an https
- * served document.  You can change these by setting your own custom {@link
- * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
- * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
- *
- * This significantly reduces the overhead.  It is far easier to pay the small overhead and have an
- * application that's secure and can be audited to verify that with much more ease than bolting
- * security onto an application later.
- *
- * 
- * ### What trusted context types are supported?
- *
- * | Context             | Notes          |
- * |---------------------|----------------|
- * | `$sce.HTML`         | For HTML that's safe to source into the application.  The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |
- * | `$sce.CSS`          | For CSS that's safe to source into the application.  Currently unused.  Feel free to use it in your own directives. |
- * | `$sce.MEDIA_URL`    | For URLs that are safe to render as media. Is automatically converted from string by sanitizing when needed. |
- * | `$sce.URL`          | For URLs that are safe to follow as links. Is automatically converted from string by sanitizing when needed. Note that `$sce.URL` makes a stronger statement about the URL than `$sce.MEDIA_URL` does and therefore contexts requiring values trusted for `$sce.URL` can be used anywhere that values trusted for `$sce.MEDIA_URL` are required.|
- * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application.  Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.)  

Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` or `$sce.MEDIA_URL` do and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` or `$sce.MEDIA_URL` are required. 

 The {@link $sceDelegateProvider#resourceUrlWhitelist $sceDelegateProvider#resourceUrlWhitelist()} and {@link $sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider#resourceUrlBlacklist()} can be used to restrict trusted origins for `RESOURCE_URL` |
- * | `$sce.JS`           | For JavaScript that is safe to execute in your application's context.  Currently unused.  Feel free to use it in your own directives. |
- *
- *
- * 

- * Be aware that, before AngularJS 1.7.0, `a[href]` and `img[src]` used to sanitize their
- * interpolated values directly rather than rely upon {@link ng.$sce#getTrusted `$sce.getTrusted`}.
- *
- * **As of 1.7.0, this is no longer the case.**
- *
- * Now such interpolations are marked as requiring `$sce.URL` (for `a[href]`) or `$sce.MEDIA_URL`
- * (for `img[src]`), so that the sanitization happens (via `$sce.getTrusted...`) when the `$interpolate`
- * service evaluates the expressions.
- * 

- *
- * There are no CSS or JS context bindings in AngularJS currently, so their corresponding `$sce.trustAs`
- * functions aren't useful yet. This might evolve.
- *
- * ### Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} 
- *
- *  Each element in these arrays must be one of the following:
- *
- *  - **'self'**
- *    - The special **string**, `'self'`, can be used to match against all URLs of the **same
- *      domain** as the application document using the **same protocol**.
- *  - **String** (except the special value `'self'`)
- *    - The string is matched against the full *normalized / absolute URL* of the resource
- *      being tested (substring matches are not good enough.)
- *    - There are exactly **two wildcard sequences** - `*` and `**`.  All other characters
- *      match themselves.
- *    - `*`: matches zero or more occurrences of any character other than one of the following 6
- *      characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'.  It's a useful wildcard for use
- *      in a whitelist.
- *    - `**`: matches zero or more occurrences of *any* character.  As such, it's not
- *      appropriate for use in a scheme, domain, etc. as it would match too much.  (e.g.
- *      http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
- *      not have been the intention.)  Its usage at the very end of the path is ok.  (e.g.
- *      http://foo.example.com/templates/**).
- *  - **RegExp** (*see caveat below*)
- *    - *Caveat*:  While regular expressions are powerful and offer great flexibility,  their syntax
- *      (and all the inevitable escaping) makes them *harder to maintain*.  It's easy to
- *      accidentally introduce a bug when one updates a complex expression (imho, all regexes should
- *      have good test coverage).  For instance, the use of `.` in the regex is correct only in a
- *      small number of cases.  A `.` character in the regex used when matching the scheme or a
- *      subdomain could be matched against a `:` or literal `.` that was likely not intended.   It
- *      is highly recommended to use the string patterns and only fall back to regular expressions
- *      as a last resort.
- *    - The regular expression must be an instance of RegExp (i.e. not a string.)  It is
- *      matched against the **entire** *normalized / absolute URL* of the resource being tested
- *      (even when the RegExp did not have the `^` and `$` codes.)  In addition, any flags
- *      present on the RegExp (such as multiline, global, ignoreCase) are ignored.
- *    - If you are generating your JavaScript from some other templating engine (not
- *      recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
- *      remember to escape your regular expression (and be aware that you might need more than
- *      one level of escaping depending on your templating engine and the way you interpolated
- *      the value.)  Do make use of your platform's escaping mechanism as it might be good
- *      enough before coding your own.  E.g. Ruby has
- *      [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
- *      and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
- *      Javascript lacks a similar built in function for escaping.  Take a look at Google
- *      Closure library's [goog.string.regExpEscape(s)](
- *      http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
- *
- * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.

- *     User comments

- *     By default, HTML that isn't explicitly trusted (e.g. Alice's comment) is sanitized when
- *     $sanitize is available.  If $sanitize isn't available, this results in an error instead of an
- *     exploit.

- *         self.explicitlyTrustedHtml = $sce.trustAsHtml(
- *             'Hover over this text.');
- *       }]);
- * 
- *
- * 
- * [
- *   { "name": "Alice",
- *     "htmlComment":
- *         "Is anyone reading this?"
- *   },
- *   { "name": "Bob",
- *     "htmlComment": "Yes!  Am I the only other one?"
- *   }
- * ]
- * 
- *
- * 
- *   describe('SCE doc demo', function() {
- *     it('should sanitize untrusted values', function() {
- *       expect(element.all(by.css('.htmlComment')).first().getAttribute('innerHTML'))
- *           .toBe('Is anyone reading this?');
- *     });
- *
- *     it('should NOT sanitize explicitly trusted values', function() {
- *       expect(element(by.id('explicitlyTrustedHtml')).getAttribute('innerHTML')).toBe(
- *           'Hover over this text.');
- *     });
- *   });
- * 
- * 
- *
- *
- *
- * ## Can I disable SCE completely?
- *
- * Yes, you can.  However, this is strongly discouraged.  SCE gives you a lot of security benefits
- * for little coding overhead.  It will be much harder to take an SCE disabled application and
- * either secure it on your own or enable SCE at a later stage.  It might make sense to disable SCE
- * for cases where you have a lot of existing code that was written before SCE was introduced and
- * you're migrating them a module at a time. Also do note that this is an app-wide setting, so if
- * you are writing a library, you will cause security bugs applications using it.
- *
- * That said, here's how you can completely disable SCE:
- *
- * ```
- * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
- *   // Completely disable SCE.  For demonstration purposes only!
- *   // Do not use in new projects or libraries.
- *   $sceProvider.enabled(false);
- * });
- * ```
- *

+   * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
+   *
+   * ## Strict Contextual Escaping
+   *
+   * Strict Contextual Escaping (SCE) is a mode in which AngularJS constrains bindings to only render
+   * trusted values. Its goal is to assist in writing code in a way that (a) is secure by default, and
+   * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
+   *
+   * ### Overview
+   *
+   * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in
+   * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically
+   * run security checks on them (sanitizations, whitelists, depending on context), or throw when it
+   * cannot guarantee the security of the result. That behavior depends strongly on contexts: HTML
+   * can be sanitized, but template URLs cannot, for instance.
+   *
+   * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML:
+   * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it
+   * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and
+   * render the input as-is, you will need to mark it as trusted for that context before attempting
+   * to bind it.
+   *
+   * As of version 1.2, AngularJS ships with SCE enabled by default.
+   *
+   * ### In practice
+   *
+   * Here's an example of a binding in a privileged context:
+   *
+   * ```
+   * 
+   * 

+   * ```
    *
-   * The API contract for the SCE delegate
-   * -------------------------------------
-   * The SCE delegate object must provide the following 3 methods:
+   * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user.  With SCE
+   * disabled, this application allows the user to render arbitrary HTML into the DIV, which would
+   * be an XSS security bug. In a more realistic example, one may be rendering user comments, blog
+   * articles, etc. via bindings. (HTML is just one example of a context where rendering user
+   * controlled input creates security vulnerabilities.)
+   *
+   * For the case of HTML, you might use a library, either on the client side, or on the server side,
+   * to sanitize unsafe HTML before binding to the value and rendering it in the document.
+   *
+   * How would you ensure that every place that used these types of bindings was bound to a value that
+   * was sanitized by your library (or returned as safe for rendering by your server?)  How can you
+   * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
+   * properties/fields and forgot to update the binding to the sanitized value?
+   *
+   * To be secure by default, AngularJS makes sure bindings go through that sanitization, or
+   * any similar validation process, unless there's a good reason to trust the given value in this
+   * context.  That trust is formalized with a function call. This means that as a developer, you
+   * can assume all untrusted bindings are safe. Then, to audit your code for binding security issues,
+   * you just need to ensure the values you mark as trusted indeed are safe - because they were
+   * received from your server, sanitized by your library, etc. You can organize your codebase to
+   * help with this - perhaps allowing only the files in a specific directory to do this.
+   * Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then
+   * becomes a more manageable task.
+   *
+   * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
+   * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
+   * build the trusted versions of your values.
+   *
+   * ### How does it work?
+   *
+   * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
+   * $sce.getTrusted(context, value)} rather than to the value directly.  Think of this function as
+   * a way to enforce the required security context in your data sink. Directives use {@link
+   * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs
+   * the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also,
+   * when binding without directives, AngularJS will understand the context of your bindings
+   * automatically.
+   *
+   * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
+   * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}.  Here's the actual code (slightly
+   * simplified):
    *
-   * - trustAs(contextEnum, value)
-   *     This method is used to tell the SCE service that the provided value is OK to use in the
-   *     contexts specified by contextEnum.  It must return an object that will be accepted by
-   *     getTrusted() for a compatible contextEnum and return this value.
+   * ```
+   * var ngBindHtmlDirective = ['$sce', function($sce) {
+   *   return function(scope, element, attr) {
+   *     scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
+   *       element.html(value || '');
+   *     });
+   *   };
+   * }];
+   * ```
+   *
+   * ### Impact on loading templates
+   *
+   * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
+   * `templateUrl`'s specified by {@link guide/directive directives}.
+   *
+   * By default, AngularJS only loads templates from the same domain and protocol as the application
+   * document.  This is done by calling {@link ng.$sce#getTrustedResourceUrl
+   * $sce.getTrustedResourceUrl} on the template URL.  To load templates from other domains and/or
+   * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
+   * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
+   *
+   * *Please note*:
+   * The browser's
+   * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
+   * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
+   * policy apply in addition to this and may further restrict whether the template is successfully
+   * loaded.  This means that without the right CORS policy, loading templates from a different domain
+   * won't work on all browsers.  Also, loading templates from `file://` URL does not work on some
+   * browsers.
+   *
+   * ### This feels like too much overhead
+   *
+   * It's important to remember that SCE only applies to interpolation expressions.

+   * Be aware that, before AngularJS 1.7.0, `a[href]` and `img[src]` used to sanitize their
+   * interpolated values directly rather than rely upon {@link ng.$sce#getTrusted `$sce.getTrusted`}.
+   *
+   * **As of 1.7.0, this is no longer the case.**
+   *
+   * Now such interpolations are marked as requiring `$sce.URL` (for `a[href]`) or `$sce.MEDIA_URL`
+   * (for `img[src]`), so that the sanitization happens (via `$sce.getTrusted...`) when the `$interpolate`
+   * service evaluates the expressions.
+   * 

    *
-   * - valueOf(value)
-   *     For values that were not produced by trustAs(), return them as is.  For values that were
-   *     produced by trustAs(), return the corresponding input value to trustAs.  Basically, if
-   *     trustAs is wrapping the given values into some type, this operation unwraps it when given
-   *     such a value.
+   * There are no CSS or JS context bindings in AngularJS currently, so their corresponding `$sce.trustAs`
+   * functions aren't useful yet. This might evolve.
+   *
+   * ### Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} 
+   *
+   *  Each element in these arrays must be one of the following:
+   *
+   *  - **'self'**
+   *    - The special **string**, `'self'`, can be used to match against all URLs of the **same
+   *      domain** as the application document using the **same protocol**.
+   *  - **String** (except the special value `'self'`)
+   *    - The string is matched against the full *normalized / absolute URL* of the resource
+   *      being tested (substring matches are not good enough.)
+   *    - There are exactly **two wildcard sequences** - `*` and `**`.  All other characters
+   *      match themselves.
+   *    - `*`: matches zero or more occurrences of any character other than one of the following 6
+   *      characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'.  It's a useful wildcard for use
+   *      in a whitelist.
+   *    - `**`: matches zero or more occurrences of *any* character.  As such, it's not
+   *      appropriate for use in a scheme, domain, etc. as it would match too much.  (e.g.
+   *      http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
+   *      not have been the intention.)  Its usage at the very end of the path is ok.  (e.g.
+   *      http://foo.example.com/templates/**).
+   *  - **RegExp** (*see caveat below*)
+   *    - *Caveat*:  While regular expressions are powerful and offer great flexibility,  their syntax
+   *      (and all the inevitable escaping) makes them *harder to maintain*.  It's easy to
+   *      accidentally introduce a bug when one updates a complex expression (imho, all regexes should
+   *      have good test coverage).  For instance, the use of `.` in the regex is correct only in a
+   *      small number of cases.  A `.` character in the regex used when matching the scheme or a
+   *      subdomain could be matched against a `:` or literal `.` that was likely not intended.   It
+   *      is highly recommended to use the string patterns and only fall back to regular expressions
+   *      as a last resort.
+   *    - The regular expression must be an instance of RegExp (i.e. not a string.)  It is
+   *      matched against the **entire** *normalized / absolute URL* of the resource being tested
+   *      (even when the RegExp did not have the `^` and `$` codes.)  In addition, any flags
+   *      present on the RegExp (such as multiline, global, ignoreCase) are ignored.
+   *    - If you are generating your JavaScript from some other templating engine (not
+   *      recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
+   *      remember to escape your regular expression (and be aware that you might need more than
+   *      one level of escaping depending on your templating engine and the way you interpolated
+   *      the value.)  Do make use of your platform's escaping mechanism as it might be good
+   *      enough before coding your own.  E.g. Ruby has
+   *      [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
+   *      and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
+   *      Javascript lacks a similar built in function for escaping.  Take a look at Google
+   *      Closure library's [goog.string.regExpEscape(s)](
+   *      http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
+   *
+   * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.

-   * - getTrusted(contextEnum, value)
-   *     This function should return the value that is safe to use in the context specified by
-   *     contextEnum or throw and exception otherwise.
    *
-   * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
-   * opaque or wrapped in some holder object.  That happens to be an implementation detail.  For
-   * instance, an implementation could maintain a registry of all trusted objects by context.  In
-   * such a case, trustAs() would return the same object that was passed in.  getTrusted() would
-   * return the same object passed in if it was found in the registry under a compatible context or
-   * throw an exception otherwise.  An implementation might only wrap values some of the time based
-   * on some criteria.  getTrusted() might return a value and not throw an exception for special
-   * constants or objects even if not wrapped.  All such implementations fulfill this contract.
    *
+   * ## Can I disable SCE completely?
    *
-   * A note on the inheritance model for SCE contexts
-   * ------------------------------------------------
-   * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types.  This
-   * is purely an implementation details.
+   * Yes, you can.  However, this is strongly discouraged.  SCE gives you a lot of security benefits
+   * for little coding overhead.  It will be much harder to take an SCE disabled application and
+   * either secure it on your own or enable SCE at a later stage.  It might make sense to disable SCE
+   * for cases where you have a lot of existing code that was written before SCE was introduced and
+   * you're migrating them a module at a time. Also do note that this is an app-wide setting, so if
+   * you are writing a library, you will cause security bugs applications using it.
    *
-   * The contract is simply this:
+   * That said, here's how you can completely disable SCE:
    *
-   *     getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
-   *     will also succeed.
+   * ```
+   * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
+   *   // Completely disable SCE.  For demonstration purposes only!
+   *   // Do not use in new projects or libraries.
+   *   $sceProvider.enabled(false);
+   * });
+   * ```
    *
-   * Inheritance happens to capture this in a natural way. In some future, we may not use
-   * inheritance anymore. That is OK because no code outside of sce.js and sceSpecs.js would need to
-   * be aware of this detail.

- *
- * Implementation Notes for non-IE browsers
- * ----------------------------------------
- * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
- * results both in the normalizing and parsing of the URL.  Normalizing means that a relative
- * URL will be resolved into an absolute URL in the context of the application document.
- * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
- * properties are all populated to reflect the normalized URL.  This approach has wide
- * compatibility - Safari 1+, Mozilla 1+ etc.  See
- * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
- *
- * Implementation Notes for IE
- * ---------------------------
- * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
- * browsers.  However, the parsed components will not be set if the URL assigned did not specify
- * them.  (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.)  We
- * work around that by performing the parsing in a 2nd step by taking a previously normalized
- * URL (e.g. by assigning to a.href) and assigning it a.href again.  This correctly populates the
- * properties such as protocol, hostname, port, etc.

+   * Implementation Notes for non-IE browsers
+   * ----------------------------------------
+   * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
+   * results both in the normalizing and parsing of the URL.  Normalizing means that a relative
+   * URL will be resolved into an absolute URL in the context of the application document.
+   * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
+   * properties are all populated to reflect the normalized URL.  This approach has wide
+   * compatibility - Safari 1+, Mozilla 1+ etc.  See
+   * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
+   *
+   * Implementation Notes for IE
+   * ---------------------------
+   * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
+   * browsers.  However, the parsed components will not be set if the URL assigned did not specify
+   * them.  (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.)  We
+   * work around that by performing the parsing in a 2nd step by taking a previously normalized
+   * URL (e.g. by assigning to a.href) and assigning it a.href again.  This correctly populates the
+   * properties such as protocol, hostname, port, etc.

- * @description
- *
- * Filters are just functions which transform input to an output. However filters need to be
- * Dependency Injected. To achieve this a filter definition consists of a factory function which is
- * annotated with dependencies and is responsible for creating a filter function.
- *
- * 

- * **Note:** Filter names must be valid AngularJS {@link expression} identifiers, such as `uppercase` or `orderBy`.
- * Names with special characters, such as hyphens and dots, are not allowed. If you wish to namespace
- * your filters, then you can use capitalization (`myappSubsectionFilterx`) or underscores
- * (`myapp_subsection_filterx`).
- * 

- *
- * ```js
- *   // Filter registration
- *   function MyModule($provide, $filterProvider) {
- *     // create a service to demonstrate injection (not always needed)
- *     $provide.value('greet', function(name){
- *       return 'Hello ' + name + '!';
- *     });
- *
- *     // register a filter factory which uses the
- *     // greet service to demonstrate DI.
- *     $filterProvider.register('greet', function(greet){
- *       // return the filter function which uses the greet service
- *       // to generate salutation
- *       return function(text) {
- *         // filters need to be forgiving so check input validity
- *         return text && greet(text) || text;
- *       };
- *     });
- *   }
- * ```
- *
- * The filter function is registered with the `$injector` under the filter name suffix with
- * `Filter`.
- *

-/**
- * @ngdoc filter
- * @name filter
- * @kind function
- *
- * @description
- * Selects a subset of items from `array` and returns it as a new array.
- *
- * @param {Array} array The source array.
- * 

- *   **Note**: If the array contains objects that reference themselves, filtering is not possible.
- * 

- * @param {string|Object|function()} expression The predicate to be used for selecting items from
- *   `array`.
- *
- *   Can be one of:
- *
- *   - `string`: The string is used for matching against the contents of the `array`. All strings or
- *     objects with string properties in `array` that match this string will be returned. This also
- *     applies to nested object properties.
- *     The predicate can be negated by prefixing the string with `!`.
- *
- *   - `Object`: A pattern object can be used to filter specific properties on objects contained
- *     by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
- *     which have property `name` containing "M" and property `phone` containing "1". A special
- *     property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match
- *     against any property of the object or its nested object properties. That's equivalent to the
- *     simple substring match with a `string` as described above. The special property name can be
- *     overwritten, using the `anyPropertyKey` parameter.
- *     The predicate can be negated by prefixing the string with `!`.
- *     For example `{name: "!M"}` predicate will return an array of items which have property `name`
- *     not containing "M".
- *
- *     Note that a named property will match properties on the same level only, while the special
- *     `$` property will match properties on the same level or deeper. E.g. an array item like
- *     `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
- *     **will** be matched by `{$: 'John'}`.
- *
- *   - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
- *     The function is called for each element of the array, with the element, its index, and
- *     the entire array itself as arguments.
- *
- *     The final result is an array of those elements that the predicate returned true for.
- *
- * @param {function(actual, expected)|true|false} [comparator] Comparator which is used in
- *     determining if values retrieved using `expression` (when it is not a function) should be
- *     considered a match based on the expected value (from the filter expression) and actual
- *     value (from the object in the array).
- *
- *   Can be one of:
- *
- *   - `function(actual, expected)`:
- *     The function will be given the object value and the predicate value to compare and
- *     should return true if both values should be considered equal.
- *
- *   - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
- *     This is essentially strict comparison of expected and actual.
- *
- *   - `false`: A short hand for a function which will look for a substring match in a case
- *     insensitive way. Primitive values are converted to strings. Objects are not compared against
- *     primitives, unless they have a custom `toString` method (e.g. `Date` objects).
- *
- *
- *   Defaults to `false`.
- *
- * @param {string} [anyPropertyKey] The special property name that matches against any property.
- *     By default `$`.

-/**
- * @ngdoc filter
- * @name orderBy
- * @kind function
- *
- * @description
- * Returns an array containing the items from the specified `collection`, ordered by a `comparator`
- * function based on the values computed using the `expression` predicate.
- *
- * For example, `[{id: 'foo'}, {id: 'bar'}] | orderBy:'id'` would result in
- * `[{id: 'bar'}, {id: 'foo'}]`.
- *
- * The `collection` can be an Array or array-like object (e.g. NodeList, jQuery object, TypedArray,
- * String, etc).
- *
- * The `expression` can be a single predicate, or a list of predicates each serving as a tie-breaker
- * for the preceding one. The `expression` is evaluated against each item and the output is used
- * for comparing with other items.
- *
- * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in
- * ascending order.
- *
- * The comparison is done using the `comparator` function. If none is specified, a default, built-in
- * comparator is used (see below for details - in a nutshell, it compares numbers numerically and
- * strings alphabetically).
- *
- * ### Under the hood
- *
- * Ordering the specified `collection` happens in two phases:
- *
- * 1. All items are passed through the predicate (or predicates), and the returned values are saved
- *    along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed
- *    through a predicate that extracts the value of the `label` property, would be transformed to:
- *    ```
- *    {
- *      value: 'foo',
- *      type: 'string',
- *      index: ...
- *    }
- *    ```
- *    **Note:** `null` values use `'null'` as their type.
- * 2. The comparator function is used to sort the items, based on the derived values, types and
- *    indices.
- *
- * If you use a custom comparator, it will be called with pairs of objects of the form
- * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal
- * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the
- * second, or `1` otherwise.
- *
- * In order to ensure that the sorting will be deterministic across platforms, if none of the
- * specified predicates can distinguish between two items, `orderBy` will automatically introduce a
- * dummy predicate that returns the item's index as `value`.
- * (If you are using a custom comparator, make sure it can handle this predicate as well.)
- *
- * If a custom comparator still can't distinguish between two items, then they will be sorted based
- * on their index using the built-in comparator.
- *
- * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted
- * value for an item, `orderBy` will try to convert that object to a primitive value, before passing
- * it to the comparator. The following rules govern the conversion:
- *
- * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be
- *    used instead.

- *    (If the object has a `valueOf()` method that returns another object, then the returned object
- *    will be used in subsequent steps.)
- * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that
- *    returns a primitive, its return value will be used instead.

- *    (If the object has a `toString()` method that returns another object, then the returned object
- *    will be used in subsequent steps.)
- * 3. No conversion; the object itself is used.
- *
- * ### The default comparator
- *
- * The default, built-in comparator should be sufficient for most usecases. In short, it compares
- * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to
- * using their index in the original collection, sorts values of different types by type and puts
- * `undefined` and `null` values at the end of the sorted list.
- *
- * More specifically, it follows these steps to determine the relative order of items:
- *
- * 1. If the compared values are of different types:
- *    - If one of the values is undefined, consider it "greater than" the other.
- *    - Else if one of the values is null, consider it "greater than" the other.
- *    - Else compare the types themselves alphabetically.
- * 2. If both values are of type `string`, compare them alphabetically in a case- and
- *    locale-insensitive way.
- * 3. If both values are objects, compare their indices instead.
- * 4. Otherwise, return:
- *    -  `0`, if the values are equal (by strict equality comparison, i.e. using `===`).
- *    - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator).
- *    -  `1`, otherwise.
- *
- * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being
- *           saved as numbers and not strings.
- * **Note:** For the purpose of sorting, `null` and `undefined` are considered "greater than"
- *           any other value (with undefined "greater than" null). This effectively means that `null`
- *           and `undefined` values end up at the end of a list sorted in ascending order.
- * **Note:** `null` values use `'null'` as their type to be able to distinguish them from objects.
- *
- * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort.
- * @param {(Function|string|Array.)=} expression - A predicate (or list of
- *    predicates) to be used by the comparator to determine the order of elements.
- *
- *    Can be one of:
- *
- *    - `Function`: A getter function. This function will be called with each item as argument and
- *      the return value will be used for sorting.
- *    - `string`: An AngularJS expression. This expression will be evaluated against each item and the
- *      result will be used for sorting. For example, use `'label'` to sort by a property called
- *      `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`
- *      property.

- *      (The result of a constant expression is interpreted as a property name to be used for
- *      comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a
- *      property called `special name`.)

- *      An expression can be optionally prefixed with `+` or `-` to control the sorting direction,
- *      ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided,
- *      (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons.
- *    - `Array`: An array of function and/or string predicates. If a predicate cannot determine the
- *      relative order of two items, the next predicate is used as a tie-breaker.
- *
- * **Note:** If the predicate is missing or empty then it defaults to `'+'`.
- *
- * @param {boolean=} reverse - If `true`, reverse the sorting order.
- * @param {(Function)=} comparator - The comparator function used to determine the relative order of
- *    value pairs. If omitted, the built-in comparator will be used.
- *
- * @returns {Array} - The sorted array.
- *
- *
- * @example
- * ### Ordering a table with `ngRepeat`
- *
- * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by
- * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means
- * it defaults to the built-in comparator.
- *

- * @ngdoc directive
- * @name ngForm
- * @restrict EAC
- *
- * @description
- * Helper directive that makes it possible to create control groups inside a
- * {@link ng.directive:form `form`} directive.
- * These "child forms" can be used, for example, to determine the validity of a sub-group of
- * controls.
- *
- * 

- * **Note**: `ngForm` cannot be used as a replacement for `
`, because it lacks its
- * [built-in HTML functionality](https://html.spec.whatwg.org/#the-form-element).
- * Specifically, you cannot submit `ngForm` like a `` tag. That means,
- * you cannot send data to the server with `ngForm`, or integrate it with
- * {@link ng.directive:ngSubmit `ngSubmit`}.
- * 

- *
- * @param {string=} ngForm|name Name of the form. If specified, the form controller will
- *                              be published into the related scope, under this name.

- /**
- * @ngdoc directive
- * @name form
- * @restrict E
- *
- * @description
- * Directive that instantiates
- * {@link form.FormController FormController}.
- *
- * If the `name` attribute is specified, the form controller is published onto the current scope under
- * this name.
- *
- * ## Alias: {@link ng.directive:ngForm `ngForm`}
- *
- * In AngularJS, forms can be nested. This means that the outer form is valid when all of the child
- * forms are valid as well. However, browsers do not allow nesting of `` elements, so
- * AngularJS provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to
- * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group
- * of controls needs to be determined.
- *
- * ## CSS classes
- *  - `ng-valid` is set if the form is valid.
- *  - `ng-invalid` is set if the form is invalid.
- *  - `ng-pending` is set if the form is pending.
- *  - `ng-pristine` is set if the form is pristine.
- *  - `ng-dirty` is set if the form is dirty.
- *  - `ng-submitted` is set if the form was submitted.
- *
- * Keep in mind that ngAnimate can detect each of these classes when added and removed.
- *
- *
- * ## Submitting a form and preventing the default action
- *
- * Since the role of forms in client-side AngularJS applications is different than in classical
- * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
- * page reload that sends the data to the server. Instead some javascript logic should be triggered
- * to handle the form submission in an application-specific way.
- *
- * For this reason, AngularJS prevents the default action (form submission to the server) unless the
- * `` element has an `action` attribute specified.
- *
- * You can use one of the following two ways to specify what javascript method should be called when
- * a form is submitted:
- *
- * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
- * - {@link ng.directive:ngClick ngClick} directive on the first
-  *  button or input field of type submit (input[type=submit])
- *
- * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
- * or {@link ng.directive:ngClick ngClick} directives.
- * This is because of the following form submission rules in the HTML specification:
- *
- * - If a form has only one input field then hitting enter in this field triggers form submit
- * (`ngSubmit`)
- * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
- * doesn't trigger submit
- * - if a form has one or more input fields and one or more buttons or input[type=submit] then
- * hitting enter in any of the input fields will trigger the click handler on the *first* button or
- * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
- *
- * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is
- * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
- * to have access to the updated model.
- *
- * @animations
- * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.
- * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any
- * other validations that are performed within the form. Animations in ngForm are similar to how
- * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well
- * as JS animations.
- *
- * The following example shows a simple way to utilize CSS transitions to style a form element
- * that has been rendered as invalid after it has been validated:
- *
- * 
- * //be sure to include ngAnimate as a module to hook into more
- * //advanced animations
- * .my-form {
- *   transition:0.5s linear all;
- *   background: white;
- * }
- * .my-form.ng-invalid {
- *   background: red;
- *   color:white;
- * }
- * 

- *
- * @example
-    
-      
-       
-       
-       
-         userType:

+  * @ngdoc directive

+  * Directive that instantiates

+  *
+  * If the `name` attribute is specified, the form controller is published onto the current scope under
+  * this name.
+  *
+  * ## Alias: {@link ng.directive:ngForm `ngForm`}
+  *
+  * In AngularJS, forms can be nested. This means that the outer form is valid when all of the child
+  * forms are valid as well. However, browsers do not allow nesting of `` elements, so
+  * AngularJS provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to
+  * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group
+  * of controls needs to be determined.
+  *
+  * ## CSS classes
+  *  - `ng-valid` is set if the form is valid.
+  *  - `ng-invalid` is set if the form is invalid.
+  *  - `ng-pending` is set if the form is pending.
+  *  - `ng-pristine` is set if the form is pristine.
+  *  - `ng-dirty` is set if the form is dirty.
+  *  - `ng-submitted` is set if the form was submitted.
+  *
+  * Keep in mind that ngAnimate can detect each of these classes when added and removed.
+  *
+  *
+  * ## Submitting a form and preventing the default action
+  *
+  * Since the role of forms in client-side AngularJS applications is different than in classical
+  * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
+  * page reload that sends the data to the server. Instead some javascript logic should be triggered
+  * to handle the form submission in an application-specific way.
+  *
+  * For this reason, AngularJS prevents the default action (form submission to the server) unless the
+  * `` element has an `action` attribute specified.
+  *
+  * You can use one of the following two ways to specify what javascript method should be called when
+  * a form is submitted:
+  *
+  * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
+  * - {@link ng.directive:ngClick ngClick} directive on the first
+   *  button or input field of type submit (input[type=submit])
+  *
+  * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
+  * or {@link ng.directive:ngClick ngClick} directives.
+  * This is because of the following form submission rules in the HTML specification:
+  *
+  * - If a form has only one input field then hitting enter in this field triggers form submit
+  * (`ngSubmit`)
+  * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
+  * doesn't trigger submit
+  * - if a form has one or more input fields and one or more buttons or input[type=submit] then
+  * hitting enter in any of the input fields will trigger the click handler on the *first* button or
+  * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
+  *
+  * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is
+  * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
+  * to have access to the updated model.
+  *
+  * @animations
+  * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.
+  * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any
+  * other validations that are performed within the form. Animations in ngForm are similar to how
+  * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well
+  * as JS animations.
+  *
+  * The following example shows a simple way to utilize CSS transitions to style a form element
+  * that has been rendered as invalid after it has been validated:
+  *
+  * 
+  * //be sure to include ngAnimate as a module to hook into more
+  * //advanced animations
+  * .my-form {
+  *   transition:0.5s linear all;
+  *   background: white;
+  * }
+  * .my-form.ng-invalid {
+  *   background: red;
+  *   color:white;
+  * }
+  * 

+  *
+  * @example
+     
+       
+        
+        
+        
+          userType: 
+          Required!

+          userType = {{userType}}

+          myForm.input.$valid = {{myForm.input.$valid}}

+          myForm.input.$error = {{myForm.input.$error}}

+          myForm.$valid = {{myForm.$valid}}

+          myForm.$error.required = {{!!myForm.$error.required}}

+         
+       
+       
+         it('should initialize to model', function() {
+           var userType = element(by.binding('userType'));
+           var valid = element(by.binding('myForm.input.$valid'));

-   * @name input[text]
-   *
-   * @description
-   * Standard HTML text input with AngularJS data binding, inherited by most of the `input` elements.
-   *
-   *
-   * @param {string} ngModel Assignable AngularJS expression to data-bind to.
-   * @param {string=} name Property name of the form under which the control is published.
-   * @param {string=} required Adds `required` validation error key if the value is not entered.
-   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
-   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
-   *    `required` when you want to data-bind to the `required` attribute.
-   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
-   *    minlength.
-   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
-   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
-   *    any length.
-   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
-   *    that contains the regular expression body that will be converted to a regular expression
-   *    as in the ngPattern directive.
-   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
-   *    does not match a RegExp found by evaluating the AngularJS expression given in the attribute value.
-   *    If the expression evaluates to a RegExp object, then this is used directly.
-   *    If the expression evaluates to a string, then it will be converted to a RegExp
-   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
-   *    `new RegExp('^abc$')`.

-   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
-   *    start at the index of the last search's match, thus not taking the whole input value into
-   *    account.
-   * @param {string=} ngChange AngularJS expression to be executed when input changes due to user
-   *    interaction with the input element.
-   * @param {boolean=} [ngTrim=true] If set to false AngularJS will not automatically trim the input.
-   *    This parameter is ignored for input[type=password] controls, which will never trim the
-   *    input.

-   * @ngdoc input
-   * @name input[number]
-   *
-   * @description
-   * Text input with number validation and transformation. Sets the `number` validation
-   * error if not a valid number.
-   *
-   * 

-   * The model must always be of type `number` otherwise AngularJS will throw an error.
-   * Be aware that a string containing a number is not enough. See the {@link ngModel:numfmt}
-   * error docs for more information and an example of how to convert your model if necessary.

-   * ### HTML5 constraint validation and `allowInvalid`
-   *
-   * In browsers that follow the
-   * [HTML5 specification](https://html.spec.whatwg.org/multipage/forms.html#number-state-%28type=number%29),
-   * `input[number]` does not work as expected with {@link ngModelOptions `ngModelOptions.allowInvalid`}.
-   * If a non-number is entered in the input, the browser will report the value as an empty string,
-   * which means the view / model values in `ngModel` and subsequently the scope value
-   * will also be an empty string.
-   *
-   * @knownIssue
-   *
-   * ### Large numbers and `step` validation
-   *
-   * The `step` validation will not work correctly for very large numbers (e.g. 9999999999) due to
-   * Javascript's arithmetic limitations. If you need to handle large numbers, purpose-built
-   * libraries (e.g. https://github.com/MikeMcl/big.js/), can be included into AngularJS by
-   * {@link guide/forms#modifying-built-in-validators overwriting the validators}
-   * for `number` and / or `step`, or by {@link guide/forms#custom-validation applying custom validators}
-   * to an `input[text]` element. The source for `input[number]` type can be used as a starting
-   * point for both implementations.
-   *
-   * @param {string} ngModel Assignable AngularJS expression to data-bind to.
-   * @param {string=} name Property name of the form under which the control is published.
-   * @param {string=} min Sets the `min` validation error key if the value entered is less than `min`.
-   *    Can be interpolated.
-   * @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`.
-   *    Can be interpolated.
-   * @param {string=} ngMin Like `min`, sets the `min` validation error key if the value entered is less than `ngMin`,
-   *    but does not trigger HTML5 native validation. Takes an expression.
-   * @param {string=} ngMax Like `max`, sets the `max` validation error key if the value entered is greater than `ngMax`,
-   *    but does not trigger HTML5 native validation. Takes an expression.
-   * @param {string=} step Sets the `step` validation error key if the value entered does not fit the `step` constraint.
-   *    Can be interpolated.
-   * @param {string=} ngStep Like `step`, sets the `step` validation error key if the value entered does not fit the `ngStep` constraint,
-   *    but does not trigger HTML5 native validation. Takes an expression.
-   * @param {string=} required Sets `required` validation error key if the value is not entered.
-   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
-   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
-   *    `required` when you want to data-bind to the `required` attribute.
-   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
-   *    minlength.
-   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
-   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
-   *    any length.
-   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
-   *    that contains the regular expression body that will be converted to a regular expression
-   *    as in the ngPattern directive.
-   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
-   *    does not match a RegExp found by evaluating the AngularJS expression given in the attribute value.
-   *    If the expression evaluates to a RegExp object, then this is used directly.
-   *    If the expression evaluates to a string, then it will be converted to a RegExp
-   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
-   *    `new RegExp('^abc$')`.

-   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
-   *    start at the index of the last search's match, thus not taking the whole input value into
-   *    account.

-   *    interaction with the input element.

+     * ### Large numbers and `step` validation
+     *
+     * The `step` validation will not work correctly for very large numbers (e.g. 9999999999) due to
+     * Javascript's arithmetic limitations. If you need to handle large numbers, purpose-built
+     * libraries (e.g. https://github.com/MikeMcl/big.js/), can be included into AngularJS by
+     * {@link guide/forms#modifying-built-in-validators overwriting the validators}
+     * for `number` and / or `step`, or by {@link guide/forms#custom-validation applying custom validators}
+     * to an `input[text]` element. The source for `input[number]` type can be used as a starting
+     * point for both implementations.
+     *
+     * @param {string} ngModel Assignable AngularJS expression to data-bind to.
+     * @param {string=} name Property name of the form under which the control is published.
+     * @param {string=} min Sets the `min` validation error key if the value entered is less than `min`.
+     *    Can be interpolated.
+     * @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`.
+     *    Can be interpolated.
+     * @param {string=} ngMin Like `min`, sets the `min` validation error key if the value entered is less than `ngMin`,
+     *    but does not trigger HTML5 native validation. Takes an expression.
+     * @param {string=} ngMax Like `max`, sets the `max` validation error key if the value entered is greater than `ngMax`,
+     *    but does not trigger HTML5 native validation. Takes an expression.
+     * @param {string=} step Sets the `step` validation error key if the value entered does not fit the `step` constraint.
+     *    Can be interpolated.
+     * @param {string=} ngStep Like `step`, sets the `step` validation error key if the value entered does not fit the `ngStep` constraint,
+     *    but does not trigger HTML5 native validation. Takes an expression.
+     * @param {string=} required Sets `required` validation error key if the value is not entered.
+     * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
+     *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
+     *    `required` when you want to data-bind to the `required` attribute.
+     * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
+     *    minlength.
+     * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
+     *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
+     *    any length.
+     * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
+     *    that contains the regular expression body that will be converted to a regular expression
+     *    as in the ngPattern directive.
+     * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
+     *    does not match a RegExp found by evaluating the AngularJS expression given in the attribute value.
+     *    If the expression evaluates to a RegExp object, then this is used directly.
+     *    If the expression evaluates to a string, then it will be converted to a RegExp
+     *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
+     *    `new RegExp('^abc$')`.

+     *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
+     *    start at the index of the last search's match, thus not taking the whole input value into
+     *    account.
+     * @param {string=} ngChange AngularJS expression to be executed when input changes due to user
+     *    interaction with the input element.

-   * @ngdoc input
-   * @name input[radio]
-   *
-   * @description
-   * HTML radio button.
-   *
-   * **Note:**

-   * All inputs controlled by {@link ngModel ngModel} (including those of type `radio`) will use the
-   * value of their `name` attribute to determine the property under which their
-   * {@link ngModel.NgModelController NgModelController} will be published on the parent
-   * {@link form.FormController FormController}. Thus, if you use the same `name` for multiple
-   * inputs of a form (e.g. a group of radio inputs), only _one_ `NgModelController` will be
-   * published on the parent `FormController` under that name. The rest of the controllers will
-   * continue to work as expected, but you won't be able to access them as properties on the parent
-   * `FormController`.
-   *
-   * 

-   *   

-   *     In plain HTML forms, the `name` attribute is used to identify groups of radio inputs, so
-   *     that the browser can manage their state (checked/unchecked) based on the state of other
-   *     inputs in the same group.
-   *   

-   *   

-   *     In AngularJS forms, this is not necessary. The input's state will be updated based on the
-   *     value of the underlying model data.
-   *   

-   * 

-   *
-   * 

-   *   If you omit the `name` attribute on a radio input, `ngModel` will automatically assign it a
-   *   unique name.
-   * 

-   *
-   * @param {string} ngModel Assignable AngularJS expression to data-bind to.
-   * @param {string} value The value to which the `ngModel` expression should be set when selected.
-   *    Note that `value` only supports `string` values, i.e. the scope model needs to be a string,
-   *    too. Use `ngValue` if you need complex models (`number`, `object`, ...).
-   * @param {string=} name Property name of the form under which the control is published.
-   * @param {string=} ngChange AngularJS expression to be executed when input changes due to user
-   *    interaction with the input element.
-   * @param {string} ngValue AngularJS expression to which `ngModel` will be be set when the radio
-   *    is selected. Should be used instead of the `value` attribute if you need
-   *    a non-string `ngModel` (`boolean`, `array`, ...).
-   *
-   * @example
-      
-        
-         
-         

-           

-           

-           

-           color = {{color.name | json}}

-          

-          Note that `ng-value="specialValue"` sets radio item's value to be the value of `$scope.specialValue`.
-        
-        
-          it('should change state', function() {
-            var inputs = element.all(by.model('color.name'));

-
-            expect(color.getText()).toContain('blue');
-
-            inputs.get(0).click();
-            expect(color.getText()).toContain('red');
-
-            inputs.get(1).click();

-   * @ngdoc input
-   * @name input[range]
-   *
-   * @description
-   * Native range input with validation and transformation.
-   *
-   * The model for the range input must always be a `Number`.
-   *
-   * IE9 and other browsers that do not support the `range` type fall back
-   * to a text input without any default values for `min`, `max` and `step`. Model binding,
-   * validation and number parsing are nevertheless supported.
-   *
-   * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]`
-   * in a way that never allows the input to hold an invalid value. That means:
-   * - any non-numerical value is set to `(max + min) / 2`.
-   * - any numerical value that is less than the current min val, or greater than the current max val
-   * is set to the min / max val respectively.
-   * - additionally, the current `step` is respected, so the nearest value that satisfies a step
-   * is used.
-   *
-   * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range))
-   * for more info.
-   *
-   * This has the following consequences for AngularJS:
-   *
-   * Since the element value should always reflect the current model value, a range input
-   * will set the bound ngModel expression to the value that the browser has set for the
-   * input element. For example, in the following input ``,
-   * if the application sets `model.value = null`, the browser will set the input to `'50'`.
-   * AngularJS will then set the model to `50`, to prevent input and model value being out of sync.
-   *
-   * That means the model for range will immediately be set to `50` after `ngModel` has been
-   * initialized. It also means a range input can never have the required error.
-   *
-   * This does not only affect changes to the model value, but also to the values of the `min`,
-   * `max`, and `step` attributes. When these change in a way that will cause the browser to modify
-   * the input value, AngularJS will also update the model value.
-   *
-   * Automatic value adjustment also means that a range input element can never have the `required`,
-   * `min`, or `max` errors.
-   *
-   * However, `step` is currently only fully implemented by Firefox. Other browsers have problems
-   * when the step value changes dynamically - they do not adjust the element value correctly, but
-   * instead may set the `stepMismatch` error. If that's the case, the AngularJS will set the `step`
-   * error on the input, and set the model to `undefined`.
-   *
-   * Note that `input[range]` is not compatible with`ngMax`, `ngMin`, and `ngStep`, because they do
-   * not set the `min` and `max` attributes, which means that the browser won't automatically adjust
-   * the input value based on their values, and will always assume min = 0, max = 100, and step = 1.
-   *
-   * @param {string}  ngModel Assignable AngularJS expression to data-bind to.
-   * @param {string=} name Property name of the form under which the control is published.
-   * @param {string=} min Sets the `min` validation to ensure that the value entered is greater
-   *                  than `min`. Can be interpolated.
-   * @param {string=} max Sets the `max` validation to ensure that the value entered is less than `max`.
-   *                  Can be interpolated.
-   * @param {string=} step Sets the `step` validation to ensure that the value entered matches the `step`
-   *                  Can be interpolated.
-   * @param {expression=} ngChange AngularJS expression to be executed when the ngModel value changes due
-   *                      to user interaction with the input element.
-   * @param {expression=} ngChecked If the expression is truthy, then the `checked` attribute will be set on the
-   *                      element. **Note** : `ngChecked` should not be used alongside `ngModel`.
-   *                      Checkout {@link ng.directive:ngChecked ngChecked} for usage.

-   * @example
-      
-

+     * HTML radio button.
+     *
+     * **Note:**

+     * All inputs controlled by {@link ngModel ngModel} (including those of type `radio`) will use the
+     * value of their `name` attribute to determine the property under which their
+     * {@link ngModel.NgModelController NgModelController} will be published on the parent
+     * {@link form.FormController FormController}. Thus, if you use the same `name` for multiple
+     * inputs of a form (e.g. a group of radio inputs), only _one_ `NgModelController` will be
+     * published on the parent `FormController` under that name. The rest of the controllers will
+     * continue to work as expected, but you won't be able to access them as properties on the parent
+     * `FormController`.
+     *
+     * 

+     *   

+     *     In plain HTML forms, the `name` attribute is used to identify groups of radio inputs, so
+     *     that the browser can manage their state (checked/unchecked) based on the state of other
+     *     inputs in the same group.
+     *   

+     *   

+     *     In AngularJS forms, this is not necessary. The input's state will be updated based on the
+     *     value of the underlying model data.
+     *   

+     * 

+     *
+     * 

+     *   If you omit the `name` attribute on a radio input, `ngModel` will automatically assign it a
+     *   unique name.
+     * 

+     *
+     * @param {string} ngModel Assignable AngularJS expression to data-bind to.
+     * @param {string} value The value to which the `ngModel` expression should be set when selected.
+     *    Note that `value` only supports `string` values, i.e. the scope model needs to be a string,
+     *    too. Use `ngValue` if you need complex models (`number`, `object`, ...).
+     * @param {string=} name Property name of the form under which the control is published.
+     * @param {string=} ngChange AngularJS expression to be executed when input changes due to user
+     *    interaction with the input element.
+     * @param {string} ngValue AngularJS expression to which `ngModel` will be be set when the radio
+     *    is selected. Should be used instead of the `value` attribute if you need

+     * @name input[range]
+     *
+     * @description
+     * Native range input with validation and transformation.
+     *
+     * The model for the range input must always be a `Number`.
+     *
+     * IE9 and other browsers that do not support the `range` type fall back
+     * to a text input without any default values for `min`, `max` and `step`. Model binding,
+     * validation and number parsing are nevertheless supported.
+     *
+     * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]`
+     * in a way that never allows the input to hold an invalid value. That means:
+     * - any non-numerical value is set to `(max + min) / 2`.
+     * - any numerical value that is less than the current min val, or greater than the current max val
+     * is set to the min / max val respectively.
+     * - additionally, the current `step` is respected, so the nearest value that satisfies a step
+     * is used.
+     *
+     * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range))
+     * for more info.
+     *
+     * This has the following consequences for AngularJS:
+     *
+     * Since the element value should always reflect the current model value, a range input
+     * will set the bound ngModel expression to the value that the browser has set for the
+     * input element. For example, in the following input ``,
+     * if the application sets `model.value = null`, the browser will set the input to `'50'`.
+     * AngularJS will then set the model to `50`, to prevent input and model value being out of sync.
+     *
+     * That means the model for range will immediately be set to `50` after `ngModel` has been
+     * initialized. It also means a range input can never have the required error.
+     *
+     * This does not only affect changes to the model value, but also to the values of the `min`,
+     * `max`, and `step` attributes. When these change in a way that will cause the browser to modify
+     * the input value, AngularJS will also update the model value.
+     *
+     * Automatic value adjustment also means that a range input element can never have the `required`,
+     * `min`, or `max` errors.
+     *
+     * However, `step` is currently only fully implemented by Firefox. Other browsers have problems
+     * when the step value changes dynamically - they do not adjust the element value correctly, but
+     * instead may set the `stepMismatch` error. If that's the case, the AngularJS will set the `step`
+     * error on the input, and set the model to `undefined`.
+     *
+     * Note that `input[range]` is not compatible with`ngMax`, `ngMin`, and `ngStep`, because they do
+     * not set the `min` and `max` attributes, which means that the browser won't automatically adjust
+     * the input value based on their values, and will always assume min = 0, max = 100, and step = 1.
+     *

+     * @param {string=} name Property name of the form under which the control is published.

- * @ngdoc directive
- * @name textarea
- * @restrict E
- *
- * @description
- * HTML textarea element control with AngularJS data-binding. The data-binding and validation
- * properties of this element are exactly the same as those of the
- * {@link ng.directive:input input element}.
- *
- * @param {string} ngModel Assignable AngularJS expression to data-bind to.
- * @param {string=} name Property name of the form under which the control is published.
- * @param {string=} required Sets `required` validation error key if the value is not entered.
- * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
- *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
- *    `required` when you want to data-bind to the `required` attribute.
- * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
- *    minlength.
- * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
- *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of any
- *    length.
- * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
- *    does not match a RegExp found by evaluating the AngularJS expression given in the attribute value.
- *    If the expression evaluates to a RegExp object, then this is used directly.
- *    If the expression evaluates to a string, then it will be converted to a RegExp
- *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
- *    `new RegExp('^abc$')`.

- *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
- *    start at the index of the last search's match, thus not taking the whole input value into
- *    account.
- * @param {string=} ngChange AngularJS expression to be executed when input changes due to user
- *    interaction with the input element.
- * @param {boolean=} [ngTrim=true] If set to false AngularJS will not automatically trim the input.

-/**
- * @ngdoc type
- * @name ngModel.NgModelController
- * @property {*} $viewValue The actual value from the control's view. For `input` elements, this is a
- * String. See {@link ngModel.NgModelController#$setViewValue} for information about when the $viewValue
- * is set.
- *
- * @property {*} $modelValue The value in the model that the control is bound to.
- *
- * @property {Array.} $parsers Array of functions to execute, as a pipeline, whenever
- *  the control updates the ngModelController with a new {@link ngModel.NgModelController#$viewValue
-    `$viewValue`} from the DOM, usually via user input.
-    See {@link ngModel.NgModelController#$setViewValue `$setViewValue()`} for a detailed lifecycle explanation.
-    Note that the `$parsers` are not called when the bound ngModel expression changes programmatically.
-
-  The functions are called in array order, each passing
-    its return value through to the next. The last return value is forwarded to the
-    {@link ngModel.NgModelController#$validators `$validators`} collection.
-
-  Parsers are used to sanitize / convert the {@link ngModel.NgModelController#$viewValue
-    `$viewValue`}.
-
-  Returning `undefined` from a parser means a parse error occurred. In that case,
-    no {@link ngModel.NgModelController#$validators `$validators`} will run and the `ngModel`
-    will be set to `undefined` unless {@link ngModelOptions `ngModelOptions.allowInvalid`}
-    is set to `true`. The parse error is stored in `ngModel.$error.parse`.
-
-  This simple example shows a parser that would convert text input value to lowercase:
- * ```js
- * function parse(value) {
- *   if (value) {
- *     return value.toLowerCase();
- *   }
- * }
- * ngModelController.$parsers.push(parse);
- * ```

- *
- * @property {Array.} $formatters Array of functions to execute, as a pipeline, whenever
-    the bound ngModel expression changes programmatically. The `$formatters` are not called when the
-    value of the control is changed by user interaction.
-
-  Formatters are used to format / convert the {@link ngModel.NgModelController#$modelValue
-    `$modelValue`} for display in the control.
-
-  The functions are called in reverse array order, each passing the value through to the
-    next. The last return value is used as the actual DOM value.
-
-  This simple example shows a formatter that would convert the model value to uppercase:
-
- * ```js
- * function format(value) {
- *   if (value) {
- *     return value.toUpperCase();
- *   }
- * }
- * ngModel.$formatters.push(format);
- * ```
- *
- * @property {Object.} $validators A collection of validators that are applied
- *      whenever the model value changes. The key value within the object refers to the name of the
- *      validator while the function refers to the validation operation. The validation operation is
- *      provided with the model value as an argument and must return a true or false value depending
- *      on the response of that validation.
- *
- * ```js
- * ngModel.$validators.validCharacters = function(modelValue, viewValue) {
- *   var value = modelValue || viewValue;
- *   return /[0-9]+/.test(value) &&
- *          /[a-z]+/.test(value) &&
- *          /[A-Z]+/.test(value) &&
- *          /\W+/.test(value);
- * };
- * ```
- *
- * @property {Object.} $asyncValidators A collection of validations that are expected to
- *      perform an asynchronous validation (e.g. a HTTP request). The validation function that is provided
- *      is expected to return a promise when it is run during the model validation process. Once the promise
- *      is delivered then the validation status will be set to true when fulfilled and false when rejected.
- *      When the asynchronous validators are triggered, each of the validators will run in parallel and the model
- *      value will only be updated once all validators have been fulfilled. As long as an asynchronous validator
- *      is unfulfilled, its key will be added to the controllers `$pending` property. Also, all asynchronous validators
- *      will only run once all synchronous validators have passed.
- *
- * Please note that if $http is used then it is important that the server returns a success HTTP response code
- * in order to fulfill the validation and a status level of `4xx` in order to reject the validation.
- *
- * ```js
- * ngModel.$asyncValidators.uniqueUsername = function(modelValue, viewValue) {
- *   var value = modelValue || viewValue;
- *
- *   // Lookup user by username
- *   return $http.get('/api/users/' + value).
- *      then(function resolved() {
- *        //username exists, this means validation fails
- *        return $q.reject('exists');
- *      }, function rejected() {
- *        //username does not exist, therefore this validation passes
- *        return true;
- *      });
- * };
- * ```
- *
- * @property {Array.} $viewChangeListeners Array of functions to execute whenever
- *     a change to {@link ngModel.NgModelController#$viewValue `$viewValue`} has caused a change
- *     to {@link ngModel.NgModelController#$modelValue `$modelValue`}.
- *     It is called with no arguments, and its return value is ignored.
- *     This can be used in place of additional $watches against the model value.
- *
- * @property {Object} $error An object hash with all failing validator ids as keys.
- * @property {Object} $pending An object hash with all pending validator ids as keys.
- *
- * @property {boolean} $untouched True if control has not lost focus yet.
- * @property {boolean} $touched True if control has lost focus.
- * @property {boolean} $pristine True if user has not interacted with the control yet.
- * @property {boolean} $dirty True if user has already interacted with the control.
- * @property {boolean} $valid True if there is no error.
- * @property {boolean} $invalid True if at least one error on the control.
- * @property {string} $name The name attribute of the control.
- *
- * @description
- *
- * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
- * The controller contains services for data-binding, validation, CSS updates, and value formatting
- * and parsing. It purposefully does not contain any logic which deals with DOM rendering or
- * listening to DOM events.
- * Such DOM related logic should be provided by other directives which make use of
- * `NgModelController` for data-binding to control elements.
- * AngularJS provides this DOM logic for most {@link input `input`} elements.
- * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
- * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
- *
- * @example
- * ### Custom Control Example
- * This example shows how to use `NgModelController` with a custom control to achieve
- * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
- * collaborate together to achieve the desired result.
- *
- * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
- * contents be edited in place by the user.
- *
- * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
- * module to automatically remove "bad" content like inline event listener (e.g. ``).
- * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
- * that content using the `$sce` service.
- *
- * 
-    
-      [contenteditable] {
-        border: 1px solid black;
-        background-color: white;
-        min-height: 20px;
-      }

+   * @restrict AC
+   * @priority 450
+   * @element ANY
+   *
+   * @param {expression} ngInit {@link guide/expression Expression} to eval.
    *
    * @description
-   * Called when the view needs to be updated. It is expected that the user of the ng-model
-   * directive will implement this method.
+   * The `ngInit` directive allows you to evaluate an expression in the
+   * current scope.
    *
-   * The `$render()` method is invoked in the following situations:
+   * 

+   * This directive can be abused to add unnecessary amounts of logic into your templates.
+   * There are only a few appropriate uses of `ngInit`:
+   * 
    
+   *   
  • aliasing special properties of {@link ng.directive:ngRepeat `ngRepeat`},
+   *     as seen in the demo below.
    • 
+   *   
  • initializing data during development, or for examples, as seen throughout these docs.
    • 
+   *   
  • injecting data via server side scripting.
    • 
+   * 

+   *
+   * Besides these few cases, you should use {@link guide/component Components} or
+   * {@link guide/controller Controllers} rather than `ngInit` to initialize values on a scope.
+   * 

    *
-   * * `$rollbackViewValue()` is called.  If we are rolling back the view value to the last
-   *   committed value then `$render()` is called to update the input control.
-   * * The value referenced by `ng-model` is changed programmatically and both the `$modelValue` and
-   *   the `$viewValue` are different from last time.
+   * 

+   * **Note**: If you have assignment in `ngInit` along with a {@link ng.$filter `filter`}, make
+   * sure you have parentheses to ensure correct operator precedence:
+   * 
+   * `
`
+   * 

+   * 

    *
-   * Since `ng-model` does not do a deep watch, `$render()` is only invoked if the values of
-   * `$modelValue` and `$viewValue` are actually different from their previous values. If `$modelValue`
-   * or `$viewValue` are objects (rather than a string or number) then `$render()` will not be
-   * invoked if you only change a property on the objects.
+   * @example
+     
+       
+     
+     

+       

+         

+            list[ {{outerIndex}} ][ {{innerIndex}} ] = {{value}};

   /**
-   * @ngdoc method
-   * @name ngModel.NgModelController#$isEmpty
+   * @ngdoc directive
+   * @name ngList
+   * @restrict A
+   * @priority 100
+   *
+   * @param {string=} ngList optional delimiter that should be used to split the value.
    *
    * @description
-   * This is called when we need to determine if the value of an input is empty.
+   * Text input that converts between a delimited string and an array of strings. The default
+   * delimiter is a comma followed by a space - equivalent to `ng-list=", "`. You can specify a custom
+   * delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`.
+   *
+   * The behaviour of the directive is affected by the use of the `ngTrim` attribute.
+   * * If `ngTrim` is set to `"false"` then whitespace around both the separator and each
+   *   list item is respected. This implies that the user of the directive is responsible for
+   *   dealing with whitespace but also allows you to use whitespace as a delimiter, such as a
+   *   tab or newline character.
+   * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected
+   *   when joining the list items back together) and whitespace around each list item is stripped
+   *   before it is added to the model.
+   *
+   * @example
+   * ### Validation
    *
-   * For instance, the required directive does this to work out if the input has data or not.
+   * 
+   *   
+   *      angular.module('listExample', [])
+   *        .controller('ExampleController', ['$scope', function($scope) {
+   *          $scope.names = ['morpheus', 'neo', 'trinity'];
+   *        }]);
+   *   
+   *   
+   *    

+   *      
+   *      
+   *        
+   *        Required!
+   *      
+   *      

+   *      names = {{names}}

+   *      myForm.namesInput.$valid = {{myForm.namesInput.$valid}}

+   *      myForm.namesInput.$error = {{myForm.namesInput.$error}}

+   *      myForm.$valid = {{myForm.$valid}}

+   *      myForm.$error.required = {{!!myForm.$error.required}}

+   *     

+   *   
+   *   
+   *     var listInput = element(by.model('names'));
+   *     var names = element(by.exactBinding('names'));
+   *     var valid = element(by.binding('myForm.namesInput.$valid'));
+   *     var error = element(by.css('span.error'));
+   *
+   *     it('should initialize to model', function() {
+   *       expect(names.getText()).toContain('["morpheus","neo","trinity"]');
+   *       expect(valid.getText()).toContain('true');
+   *       expect(error.getCssValue('display')).toBe('none');
+   *     });
+   *
+   *     it('should be invalid if empty', function() {
+   *       listInput.clear();
+   *       listInput.sendKeys('');
+   *
+   *       expect(names.getText()).toContain('');
+   *       expect(valid.getText()).toContain('false');
+   *       expect(error.getCssValue('display')).not.toBe('none');
+   *     });
+   *   
+   * 
    *
-   * The default `$isEmpty` function checks whether the value is `undefined`, `''`, `null` or `NaN`.
+   * @example
+   * ### Splitting on newline
    *
-   * You can override this for input directives whose concept of being empty is different from the
-   * default. The `checkboxInputType` directive does this because in its case a value of `false`
-   * implies empty.
+   * 
+   *   
+   *    
+   *    
{{ list | json }}

+   *   
+   *   
+   *     it("should split the text by newlines", function() {
+   *       var listInput = element(by.model('list'));
+   *       var output = element(by.binding('list | json'));

+   *       expect(output.getText()).toContain('[\n  "abc",\n  "def",\n  "ghi"\n]');

+   * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.

+   * listening to DOM events.
+   * Such DOM related logic should be provided by other directives which make use of
+   * `NgModelController` for data-binding to control elements.
+   * AngularJS provides this DOM logic for most {@link input `input`} elements.
+   * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
+   * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
    *
    * @example
-   * 
-   *   
-   *     angular.module('cancel-update-example', [])
+   * ### Custom Control Example
+   * This example shows how to use `NgModelController` with a custom control to achieve
+   * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
+   * collaborate together to achieve the desired result.
+   *
+   * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
+   * contents be edited in place by the user.
+   *
+   * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
+   * module to automatically remove "bad" content like inline event listener (e.g. ``).
+   * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
+   * that content using the `$sce` service.
+   *
+   * 
+      
+        [contenteditable] {
+          border: 1px solid black;
+          background-color: white;
+          min-height: 20px;
+        }
+  
+        .ng-invalid {
+          border: 1px solid red;
+        }
+  
+      
+      
+        angular.module('customControl', ['ngSanitize']).
+          directive('contenteditable', ['$sce', function($sce) {
+            return {

+     * future event.
+     *
+     * If you have an input that uses `ng-model-options` to set up debounced updates or updates that
+     * depend on special events such as `blur`, there can be a period when the `$viewValue` is out of
+     * sync with the ngModel's `$modelValue`.
+     *
+     * In this case, you can use `$rollbackViewValue()` to manually cancel the debounced / future update

+     *
+     * It is also possible that you run into difficulties if you try to update the ngModel's `$modelValue`
+     * programmatically before these debounced/future events have resolved/occurred, because AngularJS's
+     * dirty checking mechanism is not able to tell whether the model has actually changed or not.
+     *
+     * The `$rollbackViewValue()` method should be called before programmatically changing the model of an
+     * input which may have such events pending. This is important in order to make sure that the
+     * input field will be updated with the new model value and any pending operations are cancelled.
+     *
+     * @example
+     * 
+     *   
+     *     angular.module('cancel-update-example', [])
+     *
+     *     .controller('CancelUpdateController', ['$scope', function($scope) {

+     * @description
+     * Update the view value.
+     *
+     * This method should be called when a control wants to change the view value; typically,
+     * this is done from within a DOM event handler. For example, the {@link ng.directive:input input}
+     * directive calls it when the value of the input changes and {@link ng.directive:select select}
+     * calls it when an option is selected.
+     *
+     * When `$setViewValue` is called, the new `value` will be staged for committing through the `$parsers`
+     * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
+     * value is sent directly for processing through the `$parsers` pipeline. After this, the `$validators` and
+     * `$asyncValidators` are called and the value is applied to `$modelValue`.
+     * Finally, the value is set to the **expression** specified in the `ng-model` attribute and
+     * all the registered change listeners, in the `$viewChangeListeners` list are called.
+     *
+     * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
+     * and the `default` trigger is not listed, all those actions will remain pending until one of the
+     * `updateOn` events is triggered on the DOM element.
+     * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
+     * directive is used with a custom debounce for this particular event.
+     * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`
+     * is specified, once the timer runs out.
+     *
+     * When used with standard inputs, the view value will always be a string (which is in some cases
+     * parsed into another type, such as a `Date` object for `input[date]`.)
+     * However, custom controls might also pass objects to this method. In this case, we should make
+     * a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not
+     * perform a deep watch of objects, it only looks for a change of identity. If you only change
+     * the property of the object then ngModel will not realize that the object has changed and
+     * will not invoke the `$parsers` and `$validators` pipelines. For this reason, you should
+     * not change properties of the copy once it has been passed to `$setViewValue`.
+     * Otherwise you may cause the model value on the scope to change incorrectly.
+     *
+     * 

+     * In any case, the value passed to the method should always reflect the current value
+     * of the control. For example, if you are calling `$setViewValue` for an input element,
+     * you should pass the input DOM value. Otherwise, the control and the scope model become
+     * out of sync. It's also important to note that `$setViewValue` does not call `$render` or change
+     * the control's DOM value in any way. If we want to change the control's DOM value
+     * programmatically, we should update the `ngModel` scope expression. Its new value will be
+     * picked up by the model controller, which will run it through the `$formatters`, `$render` it
+     * to update the DOM, and finally call `$validate` on it.
+     * 

+     *
+     * @param {*} value value from the view.
+     * @param {string} trigger Event that triggered the update.

+     * - the `$modelValue` is run through the {@link ngModel.NgModelController#$formatters $formatters}
+     * and the result is set to the {@link ngModel.NgModelController#$viewValue $viewValue}
+     * - the `ng-empty` or `ng-not-empty` class is set on the element

+     *   - the {@link ngModel.NgModelController#$validators $validators} are run and

+     * This method is called by ngModel internally when the bound scope value changes.

+     * objects with a name and an id.
+     * A user enters `ap` and then selects `Apricot` from the list.
+     * Based on this, the autocomplete widget will call `$setViewValue({name: 'Apricot', id: 443})`,
+     * but the rendered value will still be `ap`.
+     * The widget can then call `ctrl.$processModelValue()` to run the model -> view
+     * pipeline again, which formats the object to the string `Apricot`,
+     * then updates the `$viewValue`, and finally renders it in the DOM.

   /**
    * @ngdoc method
-   * @name ngModel.NgModelController#$setViewValue
+   * @name ngModel.NgModelController#$setValidity
    *
    * @description
-   * Update the view value.
-   *
-   * This method should be called when a control wants to change the view value; typically,
-   * this is done from within a DOM event handler. For example, the {@link ng.directive:input input}
-   * directive calls it when the value of the input changes and {@link ng.directive:select select}
-   * calls it when an option is selected.
-   *
-   * When `$setViewValue` is called, the new `value` will be staged for committing through the `$parsers`
-   * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
-   * value is sent directly for processing through the `$parsers` pipeline. After this, the `$validators` and
-   * `$asyncValidators` are called and the value is applied to `$modelValue`.
-   * Finally, the value is set to the **expression** specified in the `ng-model` attribute and
-   * all the registered change listeners, in the `$viewChangeListeners` list are called.
-   *
-   * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
-   * and the `default` trigger is not listed, all those actions will remain pending until one of the
-   * `updateOn` events is triggered on the DOM element.
-   * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
-   * directive is used with a custom debounce for this particular event.
-   * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`
-   * is specified, once the timer runs out.
-   *
-   * When used with standard inputs, the view value will always be a string (which is in some cases
-   * parsed into another type, such as a `Date` object for `input[date]`.)
-   * However, custom controls might also pass objects to this method. In this case, we should make
-   * a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not
-   * perform a deep watch of objects, it only looks for a change of identity. If you only change
-   * the property of the object then ngModel will not realize that the object has changed and
-   * will not invoke the `$parsers` and `$validators` pipelines. For this reason, you should
-   * not change properties of the copy once it has been passed to `$setViewValue`.
-   * Otherwise you may cause the model value on the scope to change incorrectly.
-   *
-   * 

-   * In any case, the value passed to the method should always reflect the current value
-   * of the control. For example, if you are calling `$setViewValue` for an input element,
-   * you should pass the input DOM value. Otherwise, the control and the scope model become
-   * out of sync. It's also important to note that `$setViewValue` does not call `$render` or change
-   * the control's DOM value in any way. If we want to change the control's DOM value
-   * programmatically, we should update the `ngModel` scope expression. Its new value will be
-   * picked up by the model controller, which will run it through the `$formatters`, `$render` it
-   * to update the DOM, and finally call `$validate` on it.
-   * 

-   *
-   * @param {*} value value from the view.
-   * @param {string} trigger Event that triggered the update.
+   * Change the validity state, and notify the form.
+   *
+   * This method can be called within $parsers/$formatters or a custom validation implementation.
+   * However, in most cases it should be sufficient to use the `ngModel.$validators` and
+   * `ngModel.$asyncValidators` collections which will call `$setValidity` automatically.
+   *
+   * @param {string} validationErrorKey Name of the validator. The `validationErrorKey` will be assigned
+   *        to either `$error[validationErrorKey]` or `$pending[validationErrorKey]`
+   *        (for unfulfilled `$asyncValidators`), so that it is available for data-binding.
+   *        The `validationErrorKey` should be in camelCase and will get converted into dash-case
+   *        for class name. Example: `myError` will result in `ng-valid-my-error` and `ng-invalid-my-error`
+   *        classes and can be bound to as `{{ someForm.someControl.$error.myError }}`.
+   * @param {boolean} isValid Whether the current state is valid (true), invalid (false), pending (undefined),
+   *                          or skipped (null). Pending is used for unfulfilled `$asyncValidators`.
+   *                          Skipped is used by AngularJS when validators do not run because of parse errors and
+   *                          when `$asyncValidators` do not run because any of the `$validators` failed.

   /**

+   * @ngdoc directive
+   * @name ngModel
+   * @restrict A
+   * @priority 1
+   * @param {expression} ngModel assignable {@link guide/expression Expression} to bind to.
    *
    * @description
+   * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a
+   * property on the scope using {@link ngModel.NgModelController NgModelController},
+   * which is created and exposed by this directive.
+   *
+   * `ngModel` is responsible for:
+   *
+   * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
+   *   require.
+   * - Providing validation behavior (i.e. required, number, email, url).
+   * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
+   * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`,
+   *   `ng-untouched`, `ng-empty`, `ng-not-empty`) including animations.
+   * - Registering the control with its parent {@link ng.directive:form form}.
+   *
+   * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
+   * current scope. If the property doesn't already exist on this scope, it will be created
+   * implicitly and added to the scope.
+   *
+   * For best practices on using `ngModel`, see:
+   *
+   *  - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)
+   *
+   * For basic examples, how to use `ngModel`, see:
+   *
+   *  - {@link ng.directive:input input}
+   *    - {@link input[text] text}
+   *    - {@link input[checkbox] checkbox}
+   *    - {@link input[radio] radio}
+   *    - {@link input[number] number}
+   *    - {@link input[email] email}
+   *    - {@link input[url] url}
+   *    - {@link input[date] date}
+   *    - {@link input[datetime-local] datetime-local}
+   *    - {@link input[time] time}
+   *    - {@link input[month] month}
+   *    - {@link input[week] week}
+   *  - {@link ng.directive:select select}
+   *  - {@link ng.directive:textarea textarea}
+   *
+   * ## Complex Models (objects or collections)
+   *
+   * By default, `ngModel` watches the model by reference, not value. This is important to know when
+   * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the
+   * object or collection change, `ngModel` will not be notified and so the input will not be  re-rendered.
+   *
+   * The model must be assigned an entirely new object or collection before a re-rendering will occur.
+   *
+   * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression
+   * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or
+   * if the select is given the `multiple` attribute.
+   *
+   * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the
+   * first level of the object (or only changing the properties of an item in the collection if it's an array) will still
+   * not trigger a re-rendering of the model.
+   *
+   * ## CSS classes
+   * The following CSS classes are added and removed on the associated input/select/textarea element
+   * depending on the validity of the model.
+   *
+   *  - `ng-valid`: the model is valid
+   *  - `ng-invalid`: the model is invalid
+   *  - `ng-valid-[key]`: for each valid key added by `$setValidity`
+   *  - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
+   *  - `ng-pristine`: the control hasn't been interacted with yet
+   *  - `ng-dirty`: the control has been interacted with
+   *  - `ng-touched`: the control has been blurred
+   *  - `ng-untouched`: the control hasn't been blurred
+   *  - `ng-pending`: any `$asyncValidators` are unfulfilled
+   *  - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined
+   *     by the {@link ngModel.NgModelController#$isEmpty} method
+   *  - `ng-not-empty`: the view contains a non-empty value
+   *
+   * Keep in mind that ngAnimate can detect each of these classes when added and removed.
+   *
+   * @animations
+   * Animations within models are triggered when any of the associated CSS classes are added and removed
+   * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,
+   * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
+   * The animations that are triggered within ngModel are similar to how they work in ngClass and
+   * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
+   *
+   * The following example shows a simple way to utilize CSS transitions to style an input element
+   * that has been rendered as invalid after it has been validated:
    *
-   * Override the current model options settings programmatically.
+   * 
+   * //be sure to include ngAnimate as a module to hook into more
+   * //advanced animations
+   * .my-input {
+   *   transition:0.5s linear all;
+   *   background: white;
+   * }
+   * .my-input.ng-invalid {
+   *   background: red;
+   *   color:white;
+   * }
+   * 

    *
-   * The previous `ModelOptions` value will not be modified. Instead, a
-   * new `ModelOptions` object will inherit from the previous one overriding
-   * or inheriting settings that are defined in the given parameter.
+   * @example
+   * ### Basic Usage
+   * 
+       
+         
+         
+         

+          Update input to see transitions when valid/invalid.
+          Integer is a valid value.
+         

+         

+           
+         

+       
+   * 
    *
-   * See {@link ngModelOptions} for information about what options can be specified
-   * and how model option inheritance works.
+   * @example
+   * ### Binding to a getter/setter
    *
-   * 

-   * **Note:** this function only affects the options set on the `ngModelController`,
-   * and not the options on the {@link ngModelOptions} directive from which they might have been
-   * obtained initially.
-   * 

+   * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a
+   * function that returns a representation of the model when called with zero arguments, and sets
+   * the internal state of a model when called with an argument. It's sometimes useful to use this
+   * for models that have an internal representation that's different from what the model exposes
+   * to the view.
    *
-   * 

-   * **Note:** it is not possible to override the `getterSetter` option.
+   * 

+   * **Best Practice:** It's best to keep getters fast because AngularJS is likely to call them more
+   * frequently than other parts of your code.
    * 

    *
-   * @param {Object} options a hash of settings to override the previous options
-   *

-   * @name  ngModel.NgModelController#$processModelValue
-
-   * @description
-   *
-   * Runs the model -> view pipeline on the current
-   * {@link ngModel.NgModelController#$modelValue $modelValue}.
+   * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
+   * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
+   * a `
`, which will enable this behavior for all ``s within it. See
+   * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
    *
-   * The following actions are performed by this method:
-   *
-   * - the `$modelValue` is run through the {@link ngModel.NgModelController#$formatters $formatters}
-   * and the result is set to the {@link ngModel.NgModelController#$viewValue $viewValue}
-   * - the `ng-empty` or `ng-not-empty` class is set on the element
-   * - if the `$viewValue` has changed:
-   *   - {@link ngModel.NgModelController#$render $render} is called on the control
-   *   - the {@link ngModel.NgModelController#$validators $validators} are run and
-   *   the validation status is set.
-   *
-   * This method is called by ngModel internally when the bound scope value changes.
-   * Application developers usually do not have to call this function themselves.
-   *
-   * This function can be used when the `$viewValue` or the rendered DOM value are not correctly
-   * formatted and the `$modelValue` must be run through the `$formatters` again.
+   * The following example shows how to use `ngModel` with a getter/setter:
    *
    * @example
-   * Consider a text input with an autocomplete list (for fruit), where the items are
-   * objects with a name and an id.
-   * A user enters `ap` and then selects `Apricot` from the list.
-   * Based on this, the autocomplete widget will call `$setViewValue({name: 'Apricot', id: 443})`,
-   * but the rendered value will still be `ap`.
-   * The widget can then call `ctrl.$processModelValue()` to run the model -> view
-   * pipeline again, which formats the object to the string `Apricot`,
-   * then updates the `$viewValue`, and finally renders it in the DOM.

- * This method can be called within $parsers/$formatters or a custom validation implementation.
- * However, in most cases it should be sufficient to use the `ngModel.$validators` and

- *
- * @param {string} validationErrorKey Name of the validator. The `validationErrorKey` will be assigned
- *        to either `$error[validationErrorKey]` or `$pending[validationErrorKey]`
- *        (for unfulfilled `$asyncValidators`), so that it is available for data-binding.
- *        The `validationErrorKey` should be in camelCase and will get converted into dash-case
- *        for class name. Example: `myError` will result in `ng-valid-my-error` and `ng-invalid-my-error`
- *        classes and can be bound to as `{{ someForm.someControl.$error.myError }}`.
- * @param {boolean} isValid Whether the current state is valid (true), invalid (false), pending (undefined),

-/**
- * @ngdoc directive
- * @name ngModel
- * @restrict A
- * @priority 1
- * @param {expression} ngModel assignable {@link guide/expression Expression} to bind to.
- *
- * @description
- * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a
- * property on the scope using {@link ngModel.NgModelController NgModelController},
- * which is created and exposed by this directive.
- *
- * `ngModel` is responsible for:
- *
- * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
- *   require.
- * - Providing validation behavior (i.e. required, number, email, url).
- * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
- * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`,
- *   `ng-untouched`, `ng-empty`, `ng-not-empty`) including animations.
- * - Registering the control with its parent {@link ng.directive:form form}.
- *
- * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
- * current scope. If the property doesn't already exist on this scope, it will be created
- * implicitly and added to the scope.
- *
- * For best practices on using `ngModel`, see:
- *
- *  - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)
- *
- * For basic examples, how to use `ngModel`, see:
- *
- *  - {@link ng.directive:input input}
- *    - {@link input[text] text}
- *    - {@link input[checkbox] checkbox}
- *    - {@link input[radio] radio}
- *    - {@link input[number] number}
- *    - {@link input[email] email}
- *    - {@link input[url] url}
- *    - {@link input[date] date}
- *    - {@link input[datetime-local] datetime-local}
- *    - {@link input[time] time}
- *    - {@link input[month] month}
- *    - {@link input[week] week}
- *  - {@link ng.directive:select select}
- *  - {@link ng.directive:textarea textarea}
- *
- * ## Complex Models (objects or collections)
- *
- * By default, `ngModel` watches the model by reference, not value. This is important to know when
- * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the
- * object or collection change, `ngModel` will not be notified and so the input will not be  re-rendered.
- *
- * The model must be assigned an entirely new object or collection before a re-rendering will occur.
- *
- * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression
- * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or
- * if the select is given the `multiple` attribute.
- *
- * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the
- * first level of the object (or only changing the properties of an item in the collection if it's an array) will still
- * not trigger a re-rendering of the model.
- *
- * ## CSS classes
- * The following CSS classes are added and removed on the associated input/select/textarea element
- * depending on the validity of the model.
- *
- *  - `ng-valid`: the model is valid
- *  - `ng-invalid`: the model is invalid
- *  - `ng-valid-[key]`: for each valid key added by `$setValidity`
- *  - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
- *  - `ng-pristine`: the control hasn't been interacted with yet
- *  - `ng-dirty`: the control has been interacted with
- *  - `ng-touched`: the control has been blurred
- *  - `ng-untouched`: the control hasn't been blurred
- *  - `ng-pending`: any `$asyncValidators` are unfulfilled
- *  - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined
- *     by the {@link ngModel.NgModelController#$isEmpty} method
- *  - `ng-not-empty`: the view contains a non-empty value
- *
- * Keep in mind that ngAnimate can detect each of these classes when added and removed.
- *
- * @animations
- * Animations within models are triggered when any of the associated CSS classes are added and removed
- * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,
- * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
- * The animations that are triggered within ngModel are similar to how they work in ngClass and
- * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
- *
- * The following example shows a simple way to utilize CSS transitions to style an input element
- * that has been rendered as invalid after it has been validated:
- *
- * 
- * //be sure to include ngAnimate as a module to hook into more
- * //advanced animations
- * .my-input {
- *   transition:0.5s linear all;
- *   background: white;
- * }
- * .my-input.ng-invalid {
- *   background: red;
- *   color:white;
- * }
- * 

- *
- * @example
- * ### Basic Usage
- * 
-     
-       
-       
-       

-        Update input to see transitions when valid/invalid.
-        Integer is a valid value.
-       

-       

-         
-       

-     
- * 
- *
- * @example
- * ### Binding to a getter/setter
- *
- * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a
- * function that returns a representation of the model when called with zero arguments, and sets
- * the internal state of a model when called with an argument. It's sometimes useful to use this
- * for models that have an internal representation that's different from what the model exposes
- * to the view.
- *
- * 

- * **Best Practice:** It's best to keep getters fast because AngularJS is likely to call them more
- * frequently than other parts of your code.
- * 

- *
- * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
- * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
- * a `
`, which will enable this behavior for all ``s within it. See
- * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
- *
- * The following example shows how to use `ngModel` with a getter/setter:
- *
- * @example
- * 
-     
-       

-         
-           
-         
-         
user.name = 

-       

-     
-     
-       angular.module('getterSetterExample', [])
-         .controller('ExampleController', ['$scope', function($scope) {
-           var _name = 'Brian';
-           $scope.user = {
-             name: function(newName) {
-              // Note that newName can be undefined for two reasons:
-              // 1. Because it is called as a getter and thus called with no arguments
-              // 2. Because the property should actually be set to undefined. This happens e.g. if the
-              //    input is invalid
-              return arguments.length ? (_name = newName) : _name;
-             }
-           };
-         }]);
-     
- *

- * @ngdoc directive
- * @name ngModelOptions
- * @restrict A
- * @priority 10
- *
- * @description
- * This directive allows you to modify the behaviour of {@link ngModel} directives within your
- * application. You can specify an `ngModelOptions` directive on any element. All {@link ngModel}
- * directives will use the options of their nearest `ngModelOptions` ancestor.
- *
- * The `ngModelOptions` settings are found by evaluating the value of the attribute directive as
- * an AngularJS expression. This expression should evaluate to an object, whose properties contain
- * the settings. For example: `

- *   

- *     
- *   

- * 

- * ```
- *
- * the `input` element will have the following settings
- *
- * ```js
- * { allowInvalid: true, updateOn: 'default', debounce: 0 }
- * ```
- *
- * Notice that the `debounce` setting was not inherited and used the default value instead.
- *
- * You can specify that all undefined settings are automatically inherited from an ancestor by
- * including a property with key of `"*"` and value of `"$inherit"`.
- *
- * For example given the following fragment of HTML
- *
- *
- * ```html
- * 

- *   

- *     
- *   

- * 

- * ```
- *
- * the `input` element will have the following settings
- *
- * ```js
- * { allowInvalid: true, updateOn: 'default', debounce: 200 }
- * ```
- *
- * Notice that the `debounce` setting now inherits the value from the outer `
` element.
- *
- * If you are creating a reusable component then you should be careful when using `"*": "$inherit"`
- * since you may inadvertently inherit a setting in the future that changes the behavior of your component.
- *
- *
- * ## Triggering and debouncing model updates
- *
- * The `updateOn` and `debounce` properties allow you to specify a custom list of events that will
- * trigger a model update and/or a debouncing delay so that the actual update only takes place when
- * a timer expires; this timer will be reset after another change takes place.
- *
- * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
- * be different from the value in the actual model. This means that if you update the model you
- * should also invoke {@link ngModel.NgModelController#$rollbackViewValue} on the relevant input field in
- * order to make sure it is synchronized with the model and that any debounced action is canceled.
- *
- * The easiest way to reference the control's {@link ngModel.NgModelController#$rollbackViewValue}
- * method is by making sure the input is placed inside a form that has a `name` attribute. This is
- * important because `form` controllers are published to the related scope under the name in their
- * `name` attribute.
- *
- * Any pending changes will take place immediately when an enclosing form is submitted via the
- * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
- * to have access to the updated model.
- *
- * ### Overriding immediate updates
- *
- * The following example shows how to override immediate updates. Changes on the inputs within the
- * form will update the model only when the control loses focus (blur event). If `escape` key is
- * pressed while the input field is focused, the value is reset to the value in the current model.
- *
- * 
- *   
- *     

- *       

- *         

- *         

- *       

- *       
user.name = 

- *     

- *   
- *   
- *     angular.module('optionsExample', [])
- *       .controller('ExampleController', ['$scope', function($scope) {
- *         $scope.user = { name: 'say', data: '' };
- *
- *         $scope.cancel = function(e) {
- *           if (e.keyCode === 27) {
- *             $scope.userForm.userName.$rollbackViewValue();
- *           }
- *         };
- *       }]);
- *   
- *   
- *     var model = element(by.binding('user.name'));
- *     var input = element(by.model('user.name'));
- *     var other = element(by.model('user.data'));
- *
- *     it('should allow custom events', function() {
- *       input.sendKeys(' hello');
- *       input.click();
- *       expect(model.getText()).toEqual('say');
- *       other.click();
- *       expect(model.getText()).toEqual('say hello');
- *     });
- *
- *     it('should $rollbackViewValue when model changes', function() {
- *       input.sendKeys(' hello');
- *       expect(input.getAttribute('value')).toEqual('say hello');
- *       input.sendKeys(protractor.Key.ESCAPE);
- *       expect(input.getAttribute('value')).toEqual('say');
- *       other.click();
- *       expect(model.getText()).toEqual('say');
- *     });
- *   
- * 
- *
- * ### Debouncing updates
- *
- * The next example shows how to debounce model changes. Model will be updated only 1 sec after last change.
- * If the `Clear` button is pressed, any debounced action is canceled and the value becomes empty.
- *
- * 
- *   
- *     

- *       

- *         Name:
- *         
- *         

- *       

- *       
user.name = 

- *     

- *   
- *   
- *     angular.module('optionsExample', [])
- *       .controller('ExampleController', ['$scope', function($scope) {
- *         $scope.user = { name: 'say' };
- *       }]);
- *   
- * 
- *
- * ### Default events, extra triggers, and catch-all debounce values
- *
- * This example shows the relationship between "default" update events and
- * additional `updateOn` triggers.
- *
- * `default` events are those that are bound to the control, and when fired, update the `$viewValue`
- * via {@link ngModel.NgModelController#$setViewValue $setViewValue}. Every event that is not listed
- * in `updateOn` is considered a "default" event, since different control types have different
- * default events.
- *
- * The control in this example updates by "default", "click", and "blur", with different `debounce`
- * values. You can see that "click" doesn't have an individual `debounce` value -
- * therefore it uses the `*` debounce value.
- *
- * There is also a button that calls {@link ngModel.NgModelController#$setViewValue $setViewValue}
- * directly with a "custom" event. Since "custom" is not defined in the `updateOn` list,
- * it is considered a "default" event and will update the
- * control if "default" is defined in `updateOn`, and will receive the "default" debounce value.
- * Note that this is just to illustrate how custom controls would possibly call `$setViewValue`.
- *
- * You can change the `updateOn` and `debounce` configuration to test different scenarios. This
- * is done with {@link ngModel.NgModelController#$overrideModelOptions $overrideModelOptions}.

-    
-    
-      angular.module('optionsExample', [])
-        .component('modelUpdateDemo', {
-          templateUrl: 'template.html',

+  defaultModelOptions = new ModelOptions({
+    updateOn: '',

+  });
 
-        

-        
-      

-    
-  
- *
- *
- * ## Model updates and validation
- *
- * The default behaviour in `ngModel` is that the model value is set to `undefined` when the
- * validation determines that the value is invalid. By setting the `allowInvalid` property to true,
- * the model will still be updated even if the value is invalid.
- *
- *
- * ## Connecting to the scope
- *
- * By setting the `getterSetter` property to true you are telling ngModel that the `ngModel` expression
- * on the scope refers to a "getter/setter" function rather than the value itself.
- *
- * The following example shows how to bind to getter/setters:
- *
- * 
- *   
- *     

- *       

- *         
- *       

- *       
user.name = 

- *     

- *   
- *   
- *     angular.module('getterSetterExample', [])
- *       .controller('ExampleController', ['$scope', function($scope) {
- *         var _name = 'Brian';
- *         $scope.user = {
- *           name: function(newName) {
- *             return angular.isDefined(newName) ? (_name = newName) : _name;
- *           }
- *         };
- *       }]);
- *   
- * 
- *
- *
- * ## Programmatically changing options
- *
- * The `ngModelOptions` expression is only evaluated once when the directive is linked; it is not
- * watched for changes. However, it is possible to override the options on a single
- * {@link ngModel.NgModelController} instance with
- * {@link ngModel.NgModelController#$overrideModelOptions `NgModelController#$overrideModelOptions()`}.
- * See also the example for
- * {@link ngModelOptions#default-events-extra-triggers-and-catch-all-debounce-values
- * Default events, extra triggers, and catch-all debounce values}.
- *
- *
- * ## Specifying timezones
- *
- * You can specify the timezone that date/time input directives expect by providing its name in the
- * `timezone` property.
- *
- *
- * ## Formatting the value of `time` and `datetime-local`
- *
- * With the options `timeSecondsFormat` and `timeStripZeroSeconds` it is possible to adjust the value
- * that is displayed in the control. Note that browsers may apply their own formatting
- * in the user interface.

- *  
- *
- * @param {Object} ngModelOptions options to apply to {@link ngModel} directives on this element and
- *   and its descendents.
- *
- * **General options**:
- *
- *   - `updateOn`: string specifying which event should the input be bound to. You can set several
- *     events using an space delimited list. There is a special event called `default` that
- *     matches the default events belonging to the control. These are the events that are bound to
- *     the control, and when fired, update the `$viewValue` via `$setViewValue`.
- *
- *     `ngModelOptions` considers every event that is not listed in `updateOn` a "default" event,
- *     since different control types use different default events.
- *
- *     See also the section {@link ngModelOptions#triggering-and-debouncing-model-updates
- *     Triggering and debouncing model updates}.
- *
- *   - `debounce`: integer value which contains the debounce model update value in milliseconds. A
- *     value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
- *     custom value for each event. For example:
- *     ```
- *     ng-model-options="{
- *       updateOn: 'default blur',
- *       debounce: { 'default': 500, 'blur': 0 }
- *     }"
- *     ```
- *     You can use the `*` key to specify a debounce value that applies to all events that are not
- *     specifically listed. In the following example, `mouseup` would have a debounce delay of 1000:
- *     ```
- *     ng-model-options="{
- *       updateOn: 'default blur mouseup',
- *       debounce: { 'default': 500, 'blur': 0, '*': 1000 }
- *     }"
- *     ```
- *   - `allowInvalid`: boolean value which indicates that the model can be set with values that did
- *     not validate correctly instead of the default behavior of setting the model to undefined.
- *   - `getterSetter`: boolean value which determines whether or not to treat functions bound to
- *     `ngModel` as getters/setters.
- *
- *
- *  **Input-type specific options**:
- *
- *   - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
- *     ``, ``, ... . It understands UTC/GMT and the
- *     continental US time zone abbreviations, but for general use, use a time zone offset, for
- *     example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
- *     If not specified, the timezone of the browser will be used.
- *     Note that changing the timezone will have no effect on the current date, and is only applied after
- *     the next input / model change.
- *
- *   - `timeSecondsFormat`: Defines if the `time` and `datetime-local` types should show seconds and
- *     milliseconds. The option follows the format string of {@link date date filter}.
- *     By default, the options is `undefined` which is equal to `'ss.sss'` (seconds and milliseconds).
- *     The other options are `'ss'` (strips milliseconds), and `''` (empty string), which strips both
- *     seconds and milliseconds.
- *     Note that browsers that support `time` and `datetime-local` require the hour and minutes
- *     part of the time string, and may show the value differently in the user interface.
- *     {@link ngModelOptions#formatting-the-value-of-time-and-datetime-local- See the example}.
- *
- *   - `timeStripZeroSeconds`: Defines if the `time` and `datetime-local` types should strip the
- *     seconds and milliseconds from the formatted value if they are zero. This option is applied
- *     after `timeSecondsFormat`.
- *     This option can be used to make the formatting consistent over different browsers, as some
- *     browsers with support for `time` will natively hide the milliseconds and
- *     seconds if they are zero, but others won't, and browsers that don't implement these input
- *     types will always show the full string.
- *     {@link ngModelOptions#formatting-the-value-of-time-and-datetime-local- See the example}.

+    
+   *
+   *
+   * ## Model updates and validation
+   *
+   * The default behaviour in `ngModel` is that the model value is set to `undefined` when the
+   * validation determines that the value is invalid. By setting the `allowInvalid` property to true,
+   * the model will still be updated even if the value is invalid.
+   *
+   *
+   * ## Connecting to the scope
+   *
+   * By setting the `getterSetter` property to true you are telling ngModel that the `ngModel` expression
+   * on the scope refers to a "getter/setter" function rather than the value itself.
+   *
+   * The following example shows how to bind to getter/setters:
+   *
+   * 
+   *   
+   *     

+   *       

+   *         
+   *       

+   *       
user.name = 

+   *     

+   *   
+   *   
+   *     angular.module('getterSetterExample', [])
+   *       .controller('ExampleController', ['$scope', function($scope) {
+   *         var _name = 'Brian';
+   *         $scope.user = {
+   *           name: function(newName) {
+   *             return angular.isDefined(newName) ? (_name = newName) : _name;
+   *           }
+   *         };
+   *       }]);
+   *   
+   * 
+   *
+   *
+   * ## Programmatically changing options
+   *
+   * The `ngModelOptions` expression is only evaluated once when the directive is linked; it is not
+   * watched for changes. However, it is possible to override the options on a single
+   * {@link ngModel.NgModelController} instance with
+   * {@link ngModel.NgModelController#$overrideModelOptions `NgModelController#$overrideModelOptions()`}.
+   * See also the example for
+   * {@link ngModelOptions#default-events-extra-triggers-and-catch-all-debounce-values
+   * Default events, extra triggers, and catch-all debounce values}.
+   *
+   *
+   * ## Specifying timezones
+   *
+   * You can specify the timezone that date/time input directives expect by providing its name in the
+   * `timezone` property.
+   *
+   *
+   * ## Formatting the value of `time` and `datetime-local`
+   *
+   * With the options `timeSecondsFormat` and `timeStripZeroSeconds` it is possible to adjust the value
+   * that is displayed in the control. Note that browsers may apply their own formatting
+   * in the user interface.
+   *

+   *     }"
+   *     ```
+   *     You can use the `*` key to specify a debounce value that applies to all events that are not
+   *     specifically listed. In the following example, `mouseup` would have a debounce delay of 1000:
+   *     ```
+   *     ng-model-options="{
+   *       updateOn: 'default blur mouseup',

+   * @ngdoc directive
+   * @name ngPluralize
+   * @restrict EA
+   *
+   * @description
+   * `ngPluralize` is a directive that displays messages according to en-US localization rules.
+   * These rules are bundled with angular.js, but can be overridden
+   * (see {@link guide/i18n AngularJS i18n} dev guide). You configure ngPluralize directive
+   * by specifying the mappings between
+   * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
+   * and the strings to be displayed.
+   *
+   * ## Plural categories and explicit number rules
+   * There are two
+   * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
+   * in AngularJS's default en-US locale: "one" and "other".
+   *
+   * While a plural category may match many numbers (for example, in en-US locale, "other" can match
+   * any number that is not 1), an explicit number rule can only match one number. For example, the
+   * explicit number rule for "3" matches the number 3. There are examples of plural categories
+   * and explicit number rules throughout the rest of this documentation.
+   *
+   * ## Configuring ngPluralize
+   * You configure ngPluralize by providing 2 attributes: `count` and `when`.
+   * You can also provide an optional attribute, `offset`.
+   *
+   * The value of the `count` attribute can be either a string or an {@link guide/expression
+   * AngularJS expression}; these are evaluated on the current scope for its bound value.
+   *
+   * The `when` attribute specifies the mappings between plural categories and the actual
+   * string to be displayed. The value of the attribute should be a JSON object.
+   *
+   * The following example shows how to configure ngPluralize:
+   *
+   * ```html
+   * 
+   * 
+   *```
+   *
+   * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
+   * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
+   * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
+   * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
+   * show "a dozen people are viewing".
+   *
+   * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted
+   * into pluralized strings. In the previous example, AngularJS will replace `{}` with
+   * `{{personCount}}`. The closed braces `{}` is a placeholder
+   * for {{numberExpression}}.
+   *
+   * If no rule is defined for a category, then an empty string is displayed and a warning is generated.
+   * Note that some locales define more categories than `one` and `other`. For example, fr-fr defines `few` and `many`.
+   *
+   * ## Configuring ngPluralize with offset
+   * The `offset` attribute allows further customization of pluralized text, which can result in
+   * a better user experience. For example, instead of the message "4 people are viewing this document",
+   * you might display "John, Kate and 2 others are viewing this document".
+   * The offset attribute allows you to offset a number by any desired value.
+   * Let's take a look at an example:
+   *
+   * ```html
+   * 
+   * 
+   * ```
+   *
+   * Notice that we are still using two plural categories(one, other), but we added
+   * three explicit number rules 0, 1 and 2.
+   * When one person, perhaps John, views the document, "John is viewing" will be shown.
+   * When three people view the document, no explicit number rule is found, so
+   * an offset of 2 is taken off 3, and AngularJS uses 1 to decide the plural category.
+   * In this case, plural category 'one' is matched and "John, Mary and one other person are viewing"
+   * is shown.
+   *
+   * Note that when you specify offsets, you must provide explicit number rules for
+   * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
+   * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
+   * plural categories "one" and "other".
+   *
+   * @param {string|expression} count The variable to be bound to.
+   * @param {string} when The mapping between plural category to its corresponding strings.
+   * @param {number=} offset Offset to deduct from the total number.

-/**
- * @ngdoc directive
- * @name ngRef
- * @restrict A
- *
- * @description
- * The `ngRef` attribute tells AngularJS to assign the controller of a component (or a directive)
- * to the given property in the current scope. It is also possible to add the jqlite-wrapped DOM
- * element to the scope.
- *
- * If the element with `ngRef` is destroyed `null` is assigned to the property.
- *
- * Note that if you want to assign from a child into the parent scope, you must initialize the
- * target property on the parent scope, otherwise `ngRef` will assign on the child scope.
- * This commonly happens when assigning elements or components wrapped in {@link ngIf} or
- * {@link ngRepeat}. See the second example below.
- *
- *
- * @element ANY
- * @param {string} ngRef property name - A valid AngularJS expression identifier to which the
- *                       controller or jqlite-wrapped DOM element will be bound.
- * @param {string=} ngRefRead read value - The name of a directive (or component) on this element,
- *                            or the special string `$element`. If a name is provided, `ngRef` will
- *                            assign the matching controller. If `$element` is provided, the element
- *                            itself is assigned (even if a controller is available).
- *
- *
- * @example
- * ### Simple toggle
- * This example shows how the controller of the component toggle
- * is reused in the template through the scope to use its logic.
- * 
- *   
- *     
- *     
- *     

- *       You are using a component in the same template to show it.
- *     

- *   
- *   
- *     angular.module('myApp', [])
- *     .component('myToggle', {
- *       controller: function ToggleController() {
- *         var opened = false;
- *         this.isOpen = function() { return opened; };
- *         this.toggle = function() { opened = !opened; };
- *       }
- *     });
- *   
- *   
- *      it('should publish the toggle into the scope', function() {
- *        var toggle = element(by.buttonText('Toggle'));
- *        expect(toggle.evaluate('myToggle.isOpen()')).toEqual(false);
- *        toggle.click();
- *        expect(toggle.evaluate('myToggle.isOpen()')).toEqual(true);
- *      });
- *   
- * 
- *
- * @example
- * ### ngRef inside scopes
- * This example shows how `ngRef` works with child scopes. The `ngRepeat`-ed `myWrapper` components
- * are assigned to the scope of `myRoot`, because the `toggles` property has been initialized.
- * The repeated `myToggle` components are published to the child scopes created by `ngRepeat`.
- * `ngIf` behaves similarly - the assignment of `myToggle` happens in the `ngIf` child scope,
- * because the target property has not been initialized on the `myRoot` component controller.
- *
- * 
- *   
- *     
- *   
- *   
- *     angular.module('myApp', [])
- *     .component('myRoot', {
- *       templateUrl: 'root.html',
- *       controller: function() {
- *         this.wrappers = []; // initialize the array so that the wrappers are assigned into the parent scope
- *       }
- *     })
- *     .component('myToggle', {
- *       template: 'myToggle',
- *       transclude: true,
- *       controller: function ToggleController() {
- *         var opened = false;
- *         this.isOpen = function() { return opened; };
- *         this.toggle = function() { opened = !opened; };
- *       }
- *     })
- *     .component('myWrapper', {
- *       transclude: true,

-/**
- * @ngdoc directive
- * @name ngRepeat
- * @multiElement
- * @restrict A
- *
- * @description
- * The `ngRepeat` directive instantiates a template once per item from a collection. Each template
- * instance gets its own scope, where the given loop variable is set to the current collection item,
- * and `$index` is set to the item index or key.
- *
- * Special properties are exposed on the local scope of each template instance, including:
- *
- * | Variable  | Type            | Details                                                                     |
- * |-----------|-----------------|-----------------------------------------------------------------------------|
- * | `$index`  | {@type number}  | iterator offset of the repeated element (0..length-1)                       |
- * | `$first`  | {@type boolean} | true if the repeated element is first in the iterator.                      |
- * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |
- * | `$last`   | {@type boolean} | true if the repeated element is last in the iterator.                       |
- * | `$even`   | {@type boolean} | true if the iterator position `$index` is even (otherwise false).           |
- * | `$odd`    | {@type boolean} | true if the iterator position `$index` is odd (otherwise false).            |
- *
- * 

- *   Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}.
- *   This may be useful when, for instance, nesting ngRepeats.
- * 

- *
- *
- * ## Iterating over object properties
- *
- * It is possible to get `ngRepeat` to iterate over the properties of an object using the following
- * syntax:
- *
- * ```js
- * 
 ... 

- * ```
- *
- * However, there are a few limitations compared to array iteration:
- *
- * - The JavaScript specification does not define the order of keys
- *   returned for an object, so AngularJS relies on the order returned by the browser
- *   when running `for key in myObj`. Browsers generally follow the strategy of providing
- *   keys in the order in which they were defined, although there are exceptions when keys are deleted
- *   and reinstated. See the
- *   [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes).
- *
- * - `ngRepeat` will silently *ignore* object keys starting with `$`, because
- *   it's a prefix used by AngularJS for public (`$`) and private (`$$`) properties.
- *
- * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with
- *   objects, and will throw an error if used with one.
- *
- * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array
- * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could
- * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter)
- * or implement a `$watch` on the object yourself.
- *
- *
- * ## Tracking and Duplicates
- *
- * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in
- * the collection. When a change happens, `ngRepeat` then makes the corresponding changes to the DOM:
- *
- * * When an item is added, a new instance of the template is added to the DOM.
- * * When an item is removed, its template instance is removed from the DOM.
- * * When items are reordered, their respective templates are reordered in the DOM.
- *
- * To minimize creation of DOM elements, `ngRepeat` uses a function
- * to "keep track" of all items in the collection and their corresponding DOM elements.
- * For example, if an item is added to the collection, `ngRepeat` will know that all other items
- * already have DOM elements, and will not re-render them.
- *
- * All different types of tracking functions, their syntax, and and their support for duplicate
- * items in collections can be found in the
- * {@link ngRepeat#ngRepeat-arguments ngRepeat expression description}.
- *
- * 

- * **Best Practice:** If you are working with objects that have a unique identifier property, you
- * should track by this identifier instead of the object instance,
- * e.g. `item in items track by item.id`.
- * Should you reload your data later, `ngRepeat` will not have to rebuild the DOM elements for items
- * it has already rendered, even if the JavaScript objects in the collection have been substituted
- * for new ones. For large collections, this significantly improves rendering performance.
- * 

- *
- * ### Effects of DOM Element re-use
- *
- * When DOM elements are re-used, ngRepeat updates the scope for the element, which will
- * automatically update any active bindings on the template. However, other
- * functionality will not be updated, because the element is not re-created:
- *
- * - Directives are not re-compiled
- * - {@link guide/expression#one-time-binding one-time expressions} on the repeated template are not
- * updated if they have stabilized.
- *
- * The above affects all kinds of element re-use due to tracking, but may be especially visible
- * when tracking by `$index` due to the way ngRepeat re-uses elements.
- *
- * The following example shows the effects of different actions with tracking:
-
-  
-    
-      angular.module('ngRepeat', ['ngAnimate']).controller('repeatController', function($scope) {
-        var friends = [
-          {name:'John', age:25},
-          {name:'Mary', age:40},
-          {name:'Peter', age:85}
-        ];
-
-        $scope.removeFirst = function() {
-          $scope.friends.shift();
-        };
-
-        $scope.updateAge = function() {
-          $scope.friends.forEach(function(el) {
-            el.age = el.age + 5;
-          });
-        };
-
-        $scope.copy = function() {
-          $scope.friends = angular.copy($scope.friends);
-        };
-
-        $scope.reset = function() {
-          $scope.friends = angular.copy(friends);
-        };
-
-        $scope.reset();
-      });
-    
-    
-      

-        
    
-          
  1. When you click "Update Age", only the first list updates the age, because all others have
-          a one-time binding on the age property. If you then click "Copy", the current friend list
-          is copied, and now the second list updates the age, because the identity of the collection items
-          has changed and the list must be re-rendered. The 3rd and 4th list stay the same, because all the
-          items are already known according to their tracking functions.
-          
    2. 
-          
  2. When you click "Remove First", the 4th list has the wrong age on both remaining items. This is
-          due to tracking by $index: when the first collection item is removed, ngRepeat reuses the first
-          DOM element for the new first collection item, and so on. Since the age property is one-time
-          bound, the value remains from the collection item which was previously at this index.
-

- * ## Special repeat start and end points
- * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
- * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.
- * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)
- * up to and including the ending HTML tag where **ng-repeat-end** is placed.
- *
- * The example below makes use of this feature:
- * ```html
- *   

- *     Header {{ item }}
- *   

- *   

- *     Body {{ item }}
- *   

- *   

- *     Footer {{ item }}
- *   

- * ```
- *
- * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
- * ```html
- *   

- *     Header A
- *   

- *   

- *     Body A
- *   

- *   

- *     Footer A
- *   

- *   

- *     Header B
- *   

- *   

- *     Body B
- *   

- *   

- *     Footer B
- *   

- * ```
- *
- * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
- * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).
- *
- * @animations
- * | Animation                        | Occurs                              |
- * |----------------------------------|-------------------------------------|
- * | {@link ng.$animate#enter enter} | when a new item is added to the list or when an item is revealed after a filter |
- * | {@link ng.$animate#leave leave} | when an item is removed from the list or when an item is filtered out |
- * | {@link ng.$animate#move move } | when an adjacent item is filtered out causing a reorder or when the item contents are reordered |
- *
- * See the example below for defining CSS animations with ngRepeat.
- *
- * @element ANY
- * @scope
- * @priority 1000
- * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These
- *   formats are currently supported:
- *
- *   * `variable in expression` – where variable is the user defined loop variable and `expression`
- *     is a scope expression giving the collection to enumerate.
- *
- *     For example: `album in artist.albums`.
- *
- *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
- *     and `expression` is the scope expression giving the collection to enumerate.
- *
- *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
- *
- *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression
- *     which can be used to associate the objects in the collection with the DOM elements. If no tracking expression
- *     is specified, ng-repeat associates elements by identity. It is an error to have
- *     more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are
- *     mapped to the same DOM element, which is not possible.)
- *
- *     *Default tracking: $id()*: `item in items` is equivalent to `item in items track by $id(item)`.
- *     This implies that the DOM elements will be associated by item identity in the collection.
- *
- *     The built-in `$id()` function can be used to assign a unique
- *     `$$hashKey` property to each item in the collection. This property is then used as a key to associated DOM elements
- *     with the corresponding item in the collection by identity. Moving the same object would move
- *     the DOM element in the same way in the DOM.
- *     Note that the default id function does not support duplicate primitive values (`number`, `string`),
- *     but supports duplictae non-primitive values (`object`) that are *equal* in shape.
- *
- *     *Custom Expression*: It is possible to use any AngularJS expression to compute the tracking
- *     id, for example with a function, or using a property on the collection items.
- *     `item in items track by item.id` is a typical pattern when the items have a unique identifier,
- *     e.g. database id. In this case the object identity does not matter. Two objects are considered
- *     equivalent as long as their `id` property is same.
- *     Tracking by unique identifier is the most performant way and should be used whenever possible.
- *
- *     *$index*: This special property tracks the collection items by their index, and
- *     re-uses the DOM elements that match that index, e.g. `item in items track by $index`. This can
- *     be used for a performance improvement if no unique identfier is available and the identity of
- *     the collection items cannot be easily computed. It also allows duplicates.
- *
- *     

- *       Note: Re-using DOM elements can have unforeseen effects. Read the
- *       {@link ngRepeat#tracking-and-duplicates section on tracking and duplicates} for
- *       more info.
- *     

- *
- *     

- *       Note: the `track by` expression must come last - after any filters, and the alias expression:
- *       `item in items | filter:searchText as results  track by item.id`
- *     

- *
- *   * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the
- *     intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message
- *     when a filter is active on the repeater, but the filtered result set is empty.
- *
- *     For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after
- *     the items have been processed through the filter.
- *
- *     Please note that `as [variable name] is not an operator but rather a part of ngRepeat
- *     micro-syntax so it can be used only after all filters (and not as operator, inside an expression).
- *
- *     For example: `item in items | filter : x | orderBy : order | limitTo : limit as results track by item.id` .
- *
- * @example
- * This example uses `ngRepeat` to display a list of people. A filter is used to restrict the displayed
- * results by name or by age. New (entering) and removed (leaving) items are animated.

+   * @ngdoc directive
+   * @name ngRef
+   * @restrict A
+   *
+   * @description
+   * The `ngRef` attribute tells AngularJS to assign the controller of a component (or a directive)
+   * to the given property in the current scope. It is also possible to add the jqlite-wrapped DOM
+   * element to the scope.
+   *
+   * If the element with `ngRef` is destroyed `null` is assigned to the property.
+   *
+   * Note that if you want to assign from a child into the parent scope, you must initialize the
+   * target property on the parent scope, otherwise `ngRef` will assign on the child scope.
+   * This commonly happens when assigning elements or components wrapped in {@link ngIf} or
+   * {@link ngRepeat}. See the second example below.
+   *
+   *
+   * @element ANY
+   * @param {string} ngRef property name - A valid AngularJS expression identifier to which the
+   *                       controller or jqlite-wrapped DOM element will be bound.
+   * @param {string=} ngRefRead read value - The name of a directive (or component) on this element,
+   *                            or the special string `$element`. If a name is provided, `ngRef` will
+   *                            assign the matching controller. If `$element` is provided, the element
+   *                            itself is assigned (even if a controller is available).
+   *
+   *
+   * @example
+   * ### Simple toggle
+   * This example shows how the controller of the component toggle
+   * is reused in the template through the scope to use its logic.
+   * 
+   *   
+   *     
+   *     
+   *     

+   *       You are using a component in the same template to show it.
+   *     

+   *   
+   *   
+   *     angular.module('myApp', [])
+   *     .component('myToggle', {
+   *       controller: function ToggleController() {
+   *         var opened = false;
+   *         this.isOpen = function() { return opened; };
+   *         this.toggle = function() { opened = !opened; };
+   *       }
+   *     });
+   *   
+   *   
+   *      it('should publish the toggle into the scope', function() {
+   *        var toggle = element(by.buttonText('Toggle'));
+   *        expect(toggle.evaluate('myToggle.isOpen()')).toEqual(false);
+   *        toggle.click();
+   *        expect(toggle.evaluate('myToggle.isOpen()')).toEqual(true);
+   *      });
+   *   
+   * 
+   *
+   * @example
+   * ### ngRef inside scopes
+   * This example shows how `ngRef` works with child scopes. The `ngRepeat`-ed `myWrapper` components
+   * are assigned to the scope of `myRoot`, because the `toggles` property has been initialized.
+   * The repeated `myToggle` components are published to the child scopes created by `ngRepeat`.
+   * `ngIf` behaves similarly - the assignment of `myToggle` happens in the `ngIf` child scope,
+   * because the target property has not been initialized on the `myRoot` component controller.
+   *
+   * 
+   *   
+   *     
+   *   
+   *   
+   *     angular.module('myApp', [])
+   *     .component('myRoot', {
+   *       templateUrl: 'root.html',
+   *       controller: function() {
+   *         this.wrappers = []; // initialize the array so that the wrappers are assigned into the parent scope
+   *       }
+   *     })

+   *       template: 'myToggle',
+   *       transclude: true,
+   *       controller: function ToggleController() {
+   *         var opened = false;

+   *         this.toggle = function() { opened = !opened; };

+   * @ngdoc directive
+   * @name ngRepeat
+   * @multiElement
+   * @restrict A
+   *
+   * @description
+   * The `ngRepeat` directive instantiates a template once per item from a collection. Each template
+   * instance gets its own scope, where the given loop variable is set to the current collection item,
+   * and `$index` is set to the item index or key.
+   *
+   * Special properties are exposed on the local scope of each template instance, including:
+   *
+   * | Variable  | Type            | Details                                                                     |
+   * |-----------|-----------------|-----------------------------------------------------------------------------|
+   * | `$index`  | {@type number}  | iterator offset of the repeated element (0..length-1)                       |
+   * | `$first`  | {@type boolean} | true if the repeated element is first in the iterator.                      |
+   * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |
+   * | `$last`   | {@type boolean} | true if the repeated element is last in the iterator.                       |
+   * | `$even`   | {@type boolean} | true if the iterator position `$index` is even (otherwise false).           |
+   * | `$odd`    | {@type boolean} | true if the iterator position `$index` is odd (otherwise false).            |
+   *
+   * 

+   *   Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}.
+   *   This may be useful when, for instance, nesting ngRepeats.
+   * 

+   *
+   *
+   * ## Iterating over object properties
+   *
+   * It is possible to get `ngRepeat` to iterate over the properties of an object using the following
+   * syntax:
+   *
+   * ```js
+   * 
 ... 

+   * ```
+   *
+   * However, there are a few limitations compared to array iteration:
+   *
+   * - The JavaScript specification does not define the order of keys
+   *   returned for an object, so AngularJS relies on the order returned by the browser
+   *   when running `for key in myObj`. Browsers generally follow the strategy of providing
+   *   keys in the order in which they were defined, although there are exceptions when keys are deleted
+   *   and reinstated. See the
+   *   [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes).
+   *
+   * - `ngRepeat` will silently *ignore* object keys starting with `$`, because
+   *   it's a prefix used by AngularJS for public (`$`) and private (`$$`) properties.
+   *
+   * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with
+   *   objects, and will throw an error if used with one.
+   *
+   * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array
+   * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could
+   * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter)
+   * or implement a `$watch` on the object yourself.
+   *
+   *
+   * ## Tracking and Duplicates
+   *
+   * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in
+   * the collection. When a change happens, `ngRepeat` then makes the corresponding changes to the DOM:
+   *
+   * * When an item is added, a new instance of the template is added to the DOM.
+   * * When an item is removed, its template instance is removed from the DOM.
+   * * When items are reordered, their respective templates are reordered in the DOM.
+   *
+   * To minimize creation of DOM elements, `ngRepeat` uses a function
+   * to "keep track" of all items in the collection and their corresponding DOM elements.
+   * For example, if an item is added to the collection, `ngRepeat` will know that all other items
+   * already have DOM elements, and will not re-render them.
+   *
+   * All different types of tracking functions, their syntax, and and their support for duplicate
+   * items in collections can be found in the
+   * {@link ngRepeat#ngRepeat-arguments ngRepeat expression description}.
+   *
+   * 

+   * **Best Practice:** If you are working with objects that have a unique identifier property, you
+   * should track by this identifier instead of the object instance,
+   * e.g. `item in items track by item.id`.
+   * Should you reload your data later, `ngRepeat` will not have to rebuild the DOM elements for items
+   * it has already rendered, even if the JavaScript objects in the collection have been substituted
+   * for new ones. For large collections, this significantly improves rendering performance.
+   * 

+   *
+   * ### Effects of DOM Element re-use
+   *
+   * When DOM elements are re-used, ngRepeat updates the scope for the element, which will
+   * automatically update any active bindings on the template. However, other
+   * functionality will not be updated, because the element is not re-created:
+   *
+   * - Directives are not re-compiled
+   * - {@link guide/expression#one-time-binding one-time expressions} on the repeated template are not
+   * updated if they have stabilized.
+   *
+   * The above affects all kinds of element re-use due to tracking, but may be especially visible
+   * when tracking by `$index` due to the way ngRepeat re-uses elements.
+   *
+   * The following example shows the effects of different actions with tracking:
+  
+    
+      
+        angular.module('ngRepeat', ['ngAnimate']).controller('repeatController', function($scope) {
+          var friends = [
+            {name:'John', age:25},
+            {name:'Mary', age:40},
+            {name:'Peter', age:85}
+          ];
+  
+          $scope.removeFirst = function() {
+            $scope.friends.shift();
+          };
+  
+          $scope.updateAge = function() {
+            $scope.friends.forEach(function(el) {
+              el.age = el.age + 5;
+            });
+          };
+  
+          $scope.copy = function() {
+            $scope.friends = angular.copy($scope.friends);
+          };
+  
+          $scope.reset = function() {
+            $scope.friends = angular.copy(friends);
+          };
+  
+          $scope.reset();
         });
-      };
-    }
-  };

-/**
- * @ngdoc directive
- * @name ngShow
- * @multiElement
- *
- * @description
- * The `ngShow` directive shows or hides the given HTML element based on the expression provided to
- * the `ngShow` attribute.
- *
- * The element is shown or hidden by removing or adding the `.ng-hide` CSS class onto the element.
- * The `.ng-hide` CSS class is predefined in AngularJS and sets the display style to none (using an
- * `!important` flag). For CSP mode please add `angular-csp.css` to your HTML file (see
- * {@link ng.directive:ngCsp ngCsp}).
- *
- * ```html
- * 
- * 

- *
- * 
- * 

- * ```
- *
- * When the `ngShow` expression evaluates to a falsy value then the `.ng-hide` CSS class is added
- * to the class attribute on the element causing it to become hidden. When truthy, the `.ng-hide`
- * CSS class is removed from the element causing the element not to appear hidden.
- *
- * ## Why is `!important` used?
- *
- * You may be wondering why `!important` is used for the `.ng-hide` CSS class. This is because the
- * `.ng-hide` selector can be easily overridden by heavier selectors. For example, something as
- * simple as changing the display style on a HTML list item would make hidden elements appear
- * visible. This also becomes a bigger issue when dealing with CSS frameworks.
- *
- * By using `!important`, the show and hide behavior will work as expected despite any clash between
- * CSS selector specificity (when `!important` isn't used with any conflicting styles). If a
- * developer chooses to override the styling to change how to hide an element then it is just a
- * matter of using `!important` in their own CSS code.
- *
- * ### Overriding `.ng-hide`
- *
- * By default, the `.ng-hide` class will style the element with `display: none !important`. If you
- * wish to change the hide behavior with `ngShow`/`ngHide`, you can simply overwrite the styles for
- * the `.ng-hide` CSS class. Note that the selector that needs to be used is actually
- * `.ng-hide:not(.ng-hide-animate)` to cope with extra animation classes that can be added.
- *
- * ```css
- * .ng-hide:not(.ng-hide-animate) {
- *   /* These are just alternative ways of hiding an element */
- *   display: block!important;
- *   position: absolute;
- *   top: -9999px;
- *   left: -9999px;
- * }
- * ```
- *
- * By default you don't need to override anything in CSS and the animations will work around the
- * display style.
- *
- * @animations
- * | Animation                                           | Occurs                                                                                                        |
- * |-----------------------------------------------------|---------------------------------------------------------------------------------------------------------------|
- * | {@link $animate#addClass addClass} `.ng-hide`       | After the `ngShow` expression evaluates to a non truthy value and just before the contents are set to hidden. |
- * | {@link $animate#removeClass removeClass} `.ng-hide` | After the `ngShow` expression evaluates to a truthy value and just before contents are set to visible.        |
- *
- * Animations in `ngShow`/`ngHide` work with the show and hide events that are triggered when the
- * directive expression is true and false. This system works like the animation system present with
- * `ngClass` except that you must also include the `!important` flag to override the display
- * property so that the elements are not actually hidden during the animation.
- *
- * ```css
- * /* A working example can be found at the bottom of this page. */
- * .my-element.ng-hide-add, .my-element.ng-hide-remove {
- *   transition: all 0.5s linear;
- * }
- *
- * .my-element.ng-hide-add { ... }
- * .my-element.ng-hide-add.ng-hide-add-active { ... }
- * .my-element.ng-hide-remove { ... }
- * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
- * ```
- *
- * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display property
- * to block during animation states - ngAnimate will automatically handle the style toggling for you.
- *
- * @element ANY
- * @param {expression} ngShow If the {@link guide/expression expression} is truthy/falsy then the
- *                            element is shown/hidden respectively.
- *
- * @example
- * A simple example, animating the element's opacity:
- *
-  
-    
-      Show: 

-      

-        I show up when your checkbox is checked.
-      

-    
-    
-      .animate-show-hide.ng-hide {
-        opacity: 0;
-      }
+      
+      
+        

+          
    
+            
  1. When you click "Update Age", only the first list updates the age, because all others have
+            a one-time binding on the age property. If you then click "Copy", the current friend list
+            is copied, and now the second list updates the age, because the identity of the collection items
+            has changed and the list must be re-rendered. The 3rd and 4th list stay the same, because all the
+            items are already known according to their tracking functions.
+            
    2. 
+            
  2. When you click "Remove First", the 4th list has the wrong age on both remaining items. This is
+            due to tracking by $index: when the first collection item is removed, ngRepeat reuses the first
+            DOM element for the new first collection item, and so on. Since the age property is one-time
+            bound, the value remains from the collection item which was previously at this index.
+            
    3. 
+          

+  
+          
+

+

+   * ## Special repeat start and end points
+   * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
+   * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.
+   * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)
+   * up to and including the ending HTML tag where **ng-repeat-end** is placed.
+   *
+   * The example below makes use of this feature:
+   * ```html
+   *   

+   *     Header {{ item }}
+   *   

+   *   

+   *     Body {{ item }}
+   *   

+   *   

+   *     Footer {{ item }}
+   *   

+   * ```
+   *
+   * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
+   * ```html
+   *   

+   *     Header A
+   *   

+   *   

+   *     Body A
+   *   

+   *   

+   *     Footer A
+   *   

+   *   

+   *     Header B
+   *   

+   *   

+   *     Body B
+   *   

+   *   

+   *     Footer B
+   *   

+   * ```
+   *
+   * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
+   * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).

+   * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These
+   *   formats are currently supported:
+   *
+   *   * `variable in expression` – where variable is the user defined loop variable and `expression`
+   *     is a scope expression giving the collection to enumerate.
+   *
+   *     For example: `album in artist.albums`.
+   *
+   *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
+   *     and `expression` is the scope expression giving the collection to enumerate.
+   *
+   *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
+   *
+   *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression
+   *     which can be used to associate the objects in the collection with the DOM elements. If no tracking expression
+   *     is specified, ng-repeat associates elements by identity. It is an error to have
+   *     more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are
+   *     mapped to the same DOM element, which is not possible.)
+   *
+   *     *Default tracking: $id()*: `item in items` is equivalent to `item in items track by $id(item)`.
+   *     This implies that the DOM elements will be associated by item identity in the collection.
+   *
+   *     The built-in `$id()` function can be used to assign a unique
+   *     `$$hashKey` property to each item in the collection. This property is then used as a key to associated DOM elements
+   *     with the corresponding item in the collection by identity. Moving the same object would move
+   *     the DOM element in the same way in the DOM.
+   *     Note that the default id function does not support duplicate primitive values (`number`, `string`),
+   *     but supports duplictae non-primitive values (`object`) that are *equal* in shape.
+   *
+   *     *Custom Expression*: It is possible to use any AngularJS expression to compute the tracking
+   *     id, for example with a function, or using a property on the collection items.
+   *     `item in items track by item.id` is a typical pattern when the items have a unique identifier,
+   *     e.g. database id. In this case the object identity does not matter. Two objects are considered
+   *     equivalent as long as their `id` property is same.
+   *     Tracking by unique identifier is the most performant way and should be used whenever possible.
+   *
+   *     *$index*: This special property tracks the collection items by their index, and
+   *     re-uses the DOM elements that match that index, e.g. `item in items track by $index`. This can
+   *     be used for a performance improvement if no unique identfier is available and the identity of
+   *     the collection items cannot be easily computed. It also allows duplicates.
+   *
+   *     

+   *       Note: Re-using DOM elements can have unforeseen effects. Read the
+   *       {@link ngRepeat#tracking-and-duplicates section on tracking and duplicates} for
+   *       more info.
+   *     

+   *
+   *     

+   *       Note: the `track by` expression must come last - after any filters, and the alias expression:
+   *       `item in items | filter:searchText as results  track by item.id`
+   *     

+   *
+   *   * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the
+   *     intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message
+   *     when a filter is active on the repeater, but the filtered result set is empty.
+   *
+   *     For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after
+   *     the items have been processed through the filter.
+   *
+   *     Please note that `as [variable name] is not an operator but rather a part of ngRepeat
+   *     micro-syntax so it can be used only after all filters (and not as operator, inside an expression).
+   *
+   *     For example: `item in items | filter : x | orderBy : order | limitTo : limit as results track by item.id` .
+   *
+   * @example
+   * This example uses `ngRepeat` to display a list of people. A filter is used to restrict the displayed
+   * results by name or by age. New (entering) and removed (leaving) items are animated.

- * @knownIssue
- *
- * ### Flickering when using ngShow to toggle between elements
- *
- * When using {@link ngShow} and / or {@link ngHide} to toggle between elements, it can
- * happen that both the element to show and the element to hide are visible for a very short time.
- *
- * This usually happens when the {@link ngAnimate ngAnimate module} is included, but no actual animations
- * are defined for {@link ngShow} / {@link ngHide}. Internet Explorer is affected more often than
- * other browsers.
- *
- * There are several way to mitigate this problem:
- *
- * - {@link guide/animations#how-to-selectively-enable-disable-and-skip-animations Disable animations on the affected elements}.
- * - Use {@link ngIf} or {@link ngSwitch} instead of {@link ngShow} / {@link ngHide}.
- * - Use the special CSS selector `ng-hide.ng-hide-animate` to set `{display: none}` or similar on the affected elements.
- * - Use `ng-class="{'ng-hide': expression}` instead of instead of {@link ngShow} / {@link ngHide}.
- * - Define an animation on the affected elements.

-/**
- * @ngdoc directive
- * @name ngHide
- * @multiElement
- *
- * @description
- * The `ngHide` directive shows or hides the given HTML element based on the expression provided to
- * the `ngHide` attribute.
- *
- * The element is shown or hidden by removing or adding the `.ng-hide` CSS class onto the element.
- * The `.ng-hide` CSS class is predefined in AngularJS and sets the display style to none (using an
- * `!important` flag). For CSP mode please add `angular-csp.css` to your HTML file (see
- * {@link ng.directive:ngCsp ngCsp}).
- *
- * ```html
- * 
- * 

- *
- * 
- * 

- * ```
- *
- * When the `ngHide` expression evaluates to a truthy value then the `.ng-hide` CSS class is added
- * to the class attribute on the element causing it to become hidden. When falsy, the `.ng-hide`
- * CSS class is removed from the element causing the element not to appear hidden.
- *
- * ## Why is `!important` used?
- *
- * You may be wondering why `!important` is used for the `.ng-hide` CSS class. This is because the
- * `.ng-hide` selector can be easily overridden by heavier selectors. For example, something as
- * simple as changing the display style on a HTML list item would make hidden elements appear
- * visible. This also becomes a bigger issue when dealing with CSS frameworks.
- *
- * By using `!important`, the show and hide behavior will work as expected despite any clash between
- * CSS selector specificity (when `!important` isn't used with any conflicting styles). If a
- * developer chooses to override the styling to change how to hide an element then it is just a
- * matter of using `!important` in their own CSS code.
- *
- * ### Overriding `.ng-hide`
- *
- * By default, the `.ng-hide` class will style the element with `display: none !important`. If you
- * wish to change the hide behavior with `ngShow`/`ngHide`, you can simply overwrite the styles for
- * the `.ng-hide` CSS class. Note that the selector that needs to be used is actually
- * `.ng-hide:not(.ng-hide-animate)` to cope with extra animation classes that can be added.
- *
- * ```css
- * .ng-hide:not(.ng-hide-animate) {
- *   /* These are just alternative ways of hiding an element */
- *   display: block!important;
- *   position: absolute;
- *   top: -9999px;
- *   left: -9999px;
- * }
- * ```
- *
- * By default you don't need to override in CSS anything and the animations will work around the
- * display style.
- *
- * @animations
- * | Animation                                           | Occurs                                                                                                     |
- * |-----------------------------------------------------|------------------------------------------------------------------------------------------------------------|
- * | {@link $animate#addClass addClass} `.ng-hide`       | After the `ngHide` expression evaluates to a truthy value and just before the contents are set to hidden.  |
- * | {@link $animate#removeClass removeClass} `.ng-hide` | After the `ngHide` expression evaluates to a non truthy value and just before contents are set to visible. |
- *
- * Animations in `ngShow`/`ngHide` work with the show and hide events that are triggered when the
- * directive expression is true and false. This system works like the animation system present with
- * `ngClass` except that you must also include the `!important` flag to override the display
- * property so that the elements are not actually hidden during the animation.
- *
- * ```css
- * /* A working example can be found at the bottom of this page. */
- * .my-element.ng-hide-add, .my-element.ng-hide-remove {
- *   transition: all 0.5s linear;
- * }
- *
- * .my-element.ng-hide-add { ... }
- * .my-element.ng-hide-add.ng-hide-add-active { ... }
- * .my-element.ng-hide-remove { ... }
- * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
- * ```
- *
- * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display property
- * to block during animation states - ngAnimate will automatically handle the style toggling for you.
- *
- * @element ANY
- * @param {expression} ngHide If the {@link guide/expression expression} is truthy/falsy then the
- *                            element is hidden/shown respectively.

- * ### Flickering when using ngHide to toggle between elements
- *
- * When using {@link ngShow} and / or {@link ngHide} to toggle between elements, it can
- * happen that both the element to show and the element to hide are visible for a very short time.
- *
- * This usually happens when the {@link ngAnimate ngAnimate module} is included, but no actual animations
- * are defined for {@link ngShow} / {@link ngHide}. Internet Explorer is affected more often than
- * other browsers.
- *
- * There are several way to mitigate this problem:
- *
- * - {@link guide/animations#how-to-selectively-enable-disable-and-skip-animations Disable animations on the affected elements}.
- * - Use {@link ngIf} or {@link ngSwitch} instead of {@link ngShow} / {@link ngHide}.
- * - Use the special CSS selector `ng-hide.ng-hide-animate` to set `{display: none}` or similar on the affected elements.
- * - Use `ng-class="{'ng-hide': expression}` instead of instead of {@link ngShow} / {@link ngHide}.
- * - Define an animation on the affected elements.

-/**
- * @ngdoc directive
- * @name ngSwitch
- * @restrict EA
- *
- * @description
- * The `ngSwitch` directive is used to conditionally swap DOM structure on your template based on a scope expression.
- * Elements within `ngSwitch` but without `ngSwitchWhen` or `ngSwitchDefault` directives will be preserved at the location
- * as specified in the template.
- *
- * The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it
- * from the template cache), `ngSwitch` simply chooses one of the nested elements and makes it visible based on which element
- * matches the value obtained from the evaluated expression. In other words, you define a container element
- * (where you place the directive), place an expression on the **`on="..."` attribute**
- * (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place
- * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
- * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
- * attribute is displayed.
- *
- * 

- * Be aware that the attribute values to match against cannot be expressions. They are interpreted
- * as literal string values to match against.
- * For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the
- * value of the expression `$scope.someVal`.
- *

- * |----------------------------------|-------------------------------------|
- * | {@link ng.$animate#enter enter}  | after the ngSwitch contents change and the matched child element is placed inside the container |
- * | {@link ng.$animate#leave leave}  | after the ngSwitch contents change and just before the former contents are removed from the DOM |

- * On child elements add:
- *
- * * `ngSwitchWhen`: the case statement to match against. If match then this
- *   case will be displayed. If the same match appears multiple times, all the
- *   elements will be displayed. It is possible to associate multiple values to
- *   the same `ngSwitchWhen` by defining the optional attribute
- *   `ngSwitchWhenSeparator`. The separator will be used to split the value of
- *   the `ngSwitchWhen` attribute into multiple tokens, and the element will show
- *   if any of the `ngSwitch` evaluates to any of these tokens.
- * * `ngSwitchDefault`: the default case when no other case match. If there
- *   are multiple default cases, all of them will be displayed when no other
- *   case match.

+   * @multiElement
+   *
+   * @description
+   * The `ngShow` directive shows or hides the given HTML element based on the expression provided to
+   * the `ngShow` attribute.
+   *
+   * The element is shown or hidden by removing or adding the `.ng-hide` CSS class onto the element.
+   * The `.ng-hide` CSS class is predefined in AngularJS and sets the display style to none (using an
+   * `!important` flag). For CSP mode please add `angular-csp.css` to your HTML file (see
+   * {@link ng.directive:ngCsp ngCsp}).
+   *
+   * ```html
+   * 
+   * 

+   *
+   * 
+   * 

+   * ```
+   *
+   * When the `ngShow` expression evaluates to a falsy value then the `.ng-hide` CSS class is added
+   * to the class attribute on the element causing it to become hidden. When truthy, the `.ng-hide`
+   * CSS class is removed from the element causing the element not to appear hidden.
+   *
+   * ## Why is `!important` used?
+   *
+   * You may be wondering why `!important` is used for the `.ng-hide` CSS class. This is because the
+   * `.ng-hide` selector can be easily overridden by heavier selectors. For example, something as
+   * simple as changing the display style on a HTML list item would make hidden elements appear
+   * visible. This also becomes a bigger issue when dealing with CSS frameworks.
+   *
+   * By using `!important`, the show and hide behavior will work as expected despite any clash between
+   * CSS selector specificity (when `!important` isn't used with any conflicting styles). If a
+   * developer chooses to override the styling to change how to hide an element then it is just a
+   * matter of using `!important` in their own CSS code.
+   *
+   * ### Overriding `.ng-hide`
+   *
+   * By default, the `.ng-hide` class will style the element with `display: none !important`. If you
+   * wish to change the hide behavior with `ngShow`/`ngHide`, you can simply overwrite the styles for
+   * the `.ng-hide` CSS class. Note that the selector that needs to be used is actually
+   * `.ng-hide:not(.ng-hide-animate)` to cope with extra animation classes that can be added.
+   *
+   * ```css
+   * .ng-hide:not(.ng-hide-animate) {
+   *   /* These are just alternative ways of hiding an element */
+   *   display: block!important;
+   *   position: absolute;
+   *   top: -9999px;
+   *   left: -9999px;
+   * }
+   * ```
+   *
+   * By default you don't need to override anything in CSS and the animations will work around the
+   * display style.
+   *
+   * @animations
+   * | Animation                                           | Occurs                                                                                                        |
+   * |-----------------------------------------------------|---------------------------------------------------------------------------------------------------------------|
+   * | {@link $animate#addClass addClass} `.ng-hide`       | After the `ngShow` expression evaluates to a non truthy value and just before the contents are set to hidden. |
+   * | {@link $animate#removeClass removeClass} `.ng-hide` | After the `ngShow` expression evaluates to a truthy value and just before contents are set to visible.        |
+   *
+   * Animations in `ngShow`/`ngHide` work with the show and hide events that are triggered when the
+   * directive expression is true and false. This system works like the animation system present with
+   * `ngClass` except that you must also include the `!important` flag to override the display
+   * property so that the elements are not actually hidden during the animation.
+   *
+   * ```css
+   * /* A working example can be found at the bottom of this page. */
+   * .my-element.ng-hide-add, .my-element.ng-hide-remove {
+   *   transition: all 0.5s linear;
+   * }
+   *
+   * .my-element.ng-hide-add { ... }
+   * .my-element.ng-hide-add.ng-hide-add-active { ... }
+   * .my-element.ng-hide-remove { ... }
+   * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
+   * ```
+   *
+   * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display property
+   * to block during animation states - ngAnimate will automatically handle the style toggling for you.
+   *
+   * @element ANY
+   * @param {expression} ngShow If the {@link guide/expression expression} is truthy/falsy then the
+   *                            element is shown/hidden respectively.
+   *
+   * @example
+   * A simple example, animating the element's opacity:
+   *
+    
+      
+        Show: 

+        

+          I show up when your checkbox is checked.
+        

+      
+      
+        .animate-show-hide.ng-hide {
+          opacity: 0;
+        }
+  
+        .animate-show-hide.ng-hide-add,
+        .animate-show-hide.ng-hide-remove {
+          transition: all linear 0.5s;
+        }
+  
+        .check-element {
+          border: 1px solid black;

+   * @ngdoc directive
+   * @name ngHide
+   * @multiElement
+   *
+   * @description
+   * The `ngHide` directive shows or hides the given HTML element based on the expression provided to
+   * the `ngHide` attribute.
+   *
+   * The element is shown or hidden by removing or adding the `.ng-hide` CSS class onto the element.
+   * The `.ng-hide` CSS class is predefined in AngularJS and sets the display style to none (using an
+   * `!important` flag). For CSP mode please add `angular-csp.css` to your HTML file (see
+   * {@link ng.directive:ngCsp ngCsp}).
+   *
+   * ```html
+   * 
+   * 

+   *
+   * 
+   * 

+   * ```
+   *
+   * When the `ngHide` expression evaluates to a truthy value then the `.ng-hide` CSS class is added
+   * to the class attribute on the element causing it to become hidden. When falsy, the `.ng-hide`
+   * CSS class is removed from the element causing the element not to appear hidden.
+   *
+   * ## Why is `!important` used?
+   *
+   * You may be wondering why `!important` is used for the `.ng-hide` CSS class. This is because the
+   * `.ng-hide` selector can be easily overridden by heavier selectors. For example, something as
+   * simple as changing the display style on a HTML list item would make hidden elements appear
+   * visible. This also becomes a bigger issue when dealing with CSS frameworks.
+   *
+   * By using `!important`, the show and hide behavior will work as expected despite any clash between
+   * CSS selector specificity (when `!important` isn't used with any conflicting styles). If a
+   * developer chooses to override the styling to change how to hide an element then it is just a
+   * matter of using `!important` in their own CSS code.
+   *
+   * ### Overriding `.ng-hide`
+   *
+   * By default, the `.ng-hide` class will style the element with `display: none !important`. If you
+   * wish to change the hide behavior with `ngShow`/`ngHide`, you can simply overwrite the styles for
+   * the `.ng-hide` CSS class. Note that the selector that needs to be used is actually
+   * `.ng-hide:not(.ng-hide-animate)` to cope with extra animation classes that can be added.
+   *
+   * ```css
+   * .ng-hide:not(.ng-hide-animate) {
+   *   /* These are just alternative ways of hiding an element */
+   *   display: block!important;
+   *   position: absolute;
+   *   top: -9999px;
+   *   left: -9999px;
+   * }
+   * ```
+   *
+   * By default you don't need to override in CSS anything and the animations will work around the
+   * display style.
+   *
+   * @animations
+   * | Animation                                           | Occurs                                                                                                     |
+   * |-----------------------------------------------------|------------------------------------------------------------------------------------------------------------|
+   * | {@link $animate#addClass addClass} `.ng-hide`       | After the `ngHide` expression evaluates to a truthy value and just before the contents are set to hidden.  |
+   * | {@link $animate#removeClass removeClass} `.ng-hide` | After the `ngHide` expression evaluates to a non truthy value and just before contents are set to visible. |
+   *
+   * Animations in `ngShow`/`ngHide` work with the show and hide events that are triggered when the
+   * directive expression is true and false. This system works like the animation system present with
+   * `ngClass` except that you must also include the `!important` flag to override the display
+   * property so that the elements are not actually hidden during the animation.
+   *
+   * ```css
+   * /* A working example can be found at the bottom of this page. */
+   * .my-element.ng-hide-add, .my-element.ng-hide-remove {
+   *   transition: all 0.5s linear;
+   * }
+   *
+   * .my-element.ng-hide-add { ... }
+   * .my-element.ng-hide-add.ng-hide-add-active { ... }
+   * .my-element.ng-hide-remove { ... }
+   * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
+   * ```
+   *
+   * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display property
+   * to block during animation states - ngAnimate will automatically handle the style toggling for you.
+   *
+   * @element ANY
+   * @param {expression} ngHide If the {@link guide/expression expression} is truthy/falsy then the
+   *                            element is hidden/shown respectively.
+   *
+   * @example
+   * A simple example, animating the element's opacity:
+   *
+    
+      
+        Hide: 

+        

+          I hide when your checkbox is checked.

+   * @description
+   * The `ngSwitch` directive is used to conditionally swap DOM structure on your template based on a scope expression.
+   * Elements within `ngSwitch` but without `ngSwitchWhen` or `ngSwitchDefault` directives will be preserved at the location
+   * as specified in the template.
+   *
+   * The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it
+   * from the template cache), `ngSwitch` simply chooses one of the nested elements and makes it visible based on which element
+   * matches the value obtained from the evaluated expression. In other words, you define a container element
+   * (where you place the directive), place an expression on the **`on="..."` attribute**
+   * (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place
+   * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
+   * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
+   * attribute is displayed.
+   *
+   * 

+   * Be aware that the attribute values to match against cannot be expressions. They are interpreted
+   * as literal string values to match against.
+   * For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the
+   * value of the expression `$scope.someVal`.
+   *

+   *   elements will be displayed. It is possible to associate multiple values to
+   *   the same `ngSwitchWhen` by defining the optional attribute
+   *   `ngSwitchWhenSeparator`. The separator will be used to split the value of
+   *   the `ngSwitchWhen` attribute into multiple tokens, and the element will show
+   *   if any of the `ngSwitch` evaluates to any of these tokens.
+   * * `ngSwitchDefault`: the default case when no other case match. If there
+   *   are multiple default cases, all of them will be displayed when no other

-/**
- * @ngdoc directive
- * @name ngTransclude
- * @restrict EAC
- *
- * @description
- * Directive that marks the insertion point for the transcluded DOM of the nearest parent directive that uses transclusion.
- *
- * You can specify that you want to insert a named transclusion slot, instead of the default slot, by providing the slot name
- * as the value of the `ng-transclude` or `ng-transclude-slot` attribute.
- *
- * If the transcluded content is not empty (i.e. contains one or more DOM nodes, including whitespace text nodes), any existing
- * content of this element will be removed before the transcluded content is inserted.
- * If the transcluded content is empty (or only whitespace), the existing content is left intact. This lets you provide fallback
- * content in the case that no transcluded content is provided.
- *
- * @element ANY
- *
- * @param {string} ngTransclude|ngTranscludeSlot the name of the slot to insert at this point. If this is not provided, is empty
- *                                               or its value is the same as the name of the attribute then the default slot is used.
- *
- * @example
- * ### Basic transclusion
- * This example demonstrates basic transclusion of content into a component directive.
- * 
- *   
- *     
- *     

- *        

- *        

- *       {{text}}
- *     

- *   
- *   
- *      it('should have transcluded', function() {
- *        var titleElement = element(by.model('title'));
- *        titleElement.clear();
- *        titleElement.sendKeys('TITLE');
- *        var textElement = element(by.model('text'));
- *        textElement.clear();
- *        textElement.sendKeys('TEXT');
- *        expect(element(by.binding('title')).getText()).toEqual('TITLE');
- *        expect(element(by.binding('text')).getText()).toEqual('TEXT');
- *      });
- *   
- * 
- *
- * @example
- * ### Transclude fallback content
- * This example shows how to use `NgTransclude` with fallback content, that
- * is displayed if no transcluded content is provided.
- *
- * 
- * 
- * 
- * 
- * 
- * 
- * 
- *   Button2
- * 
- *

- *          expect(element(by.id('fallback')).getText()).toBe('Button1');
- *          expect(element(by.id('modified')).getText()).toBe('Button2');

- * The controller for the {@link ng.select select} directive. The controller exposes
- * a few utility methods that can be used to augment the behavior of a regular or an
- * {@link ng.ngOptions ngOptions} select element.
- *
- * @example
- * ### Set a custom error when the unknown option is selected
- *
- * This example sets a custom error "unknownValue" on the ngModelController
- * when the select element's unknown option is selected, i.e. when the model is set to a value
- * that is not matched by any option.
- *
- * 
- * 
- * 

- *   

- *     

- *     

- *     
- *       Error: The current model doesn't match any option

- *
- *     

- *

- * 
- *

- *    .controller('ExampleController', ['$scope', function($scope) {
- *      $scope.selected = null;
- *
- *      $scope.forceUnknownOption = function() {
- *        $scope.selected = 'nonsense';
- *      };
- *   }])
- *   .directive('unknownValueError', function() {
- *     return {
- *       require: ['ngModel', 'select'],
- *       link: function(scope, element, attrs, ctrls) {
- *         var ngModelCtrl = ctrls[0];
- *         var selectCtrl = ctrls[1];

- * ### Set the "required" error when the unknown option is selected.
- *
- * By default, the "required" error on the ngModelController is only set on a required select
- * when the empty option is selected. This example adds a custom directive that also sets the
- * error when the unknown option is selected.
