can you remove all the formatting changes from the PR?
also can you briefly explain the specific use case you want to achieve with this change?
ie. for what use case do you want to decorate the CacheManger?

[Warxcell]

Don't remember - I think I decided to go with Adapter Pattern in my case, but I think it's useful anyway. :)

Basically I needed to add $runtimeConfig for particular path, globally - not just for one file. So to avoid Repeat-Your-Self I could decorate CacheManager and do

if(stripos($path, 'XXX') !== false)  {
    $runtimeConfig['YY'] = ['xxx' => 'xxx']
}
return $this->decorated->getBrowserPath($path, $filter, $runtimeConfig.... );`

ok .. as long as there is a use-case I am fine adding an interface :)

[fbourigault]

The CacheManager has two responsibilities.

The first one, for the isStored, store, remove and resolve methods, is to find the right resolver and call the same method this resolver.

The second one, for the getBrowserPath, getRuntimePath and generateUrl, is to get an URL or a path.

I see here a nice opportunity to split CacheManager.

The code is quite complex, but I would start with introducing some kind of ResolverManagerInterface to move the first responsibility out of CacheManager.

i like the suggestion of @fbourigault - do you want to split the interface in the way he suggested @Warxcell ?
