nestedObjectArray usage?

[cyrillef]

export class myclass extends Serializable {

	@SerializableInfo.position(0)
	@SerializableInfo.length(1)
	@SerializableInfo.numberType(NumberType.UInt8)
	protected _one: number;

	@SerializableInfo.position(1)
	@SerializableInfo.numberType(NumberType.UInt8)
	@SerializableInfo.nestedObjectArray( ??? , 1)
	protected _two: number[];

	@SerializableInfo.position( ??? )
	@SerializableInfo.numberType(NumberType.UInt8)
	@SerializableInfo.nestedObjectArray( ??? , 2)
	protected _three: Map<number, number>;

	@SerializableInfo.position( ??? )
	@SerializableInfo.nestedObjectArray( ??? , ??? )
	protected _four: mysubclass;

I got 3 questions
1- how do I serialize an array number[]
2- how do I serialize an object like a custom one and/or a Map<>
3- how do I serialize the two above when I get a variable length. What do I put in position() or shall I remove it?
