Class IdentityMap

java.lang.Object
  com.carbonfive.flash.IdentityMap

public class IdentityMap
extends java.lang.Object

A lightweight HashMap (not all methods implemented) that wraps keys with an object that uses equivalence (==) for equals() and hashCode(). It is useful for caching objects by reference (regardless of their equals() implementation). Specifically, we needed it for handling ASObject references.
