public class NativeWeakMap extends IdScriptableObject
This is an implementation of the ES6 WeakMap class. As per the spec, keys must be ordinary objects. Since there is no defined "equality" for objects, comparisions are done strictly by object equality. Both ES6 and the java.util.WeakHashMap class have the same basic structure -- entries are removed automatically when the sole remaining reference to the key is a weak reference. Therefore, we can use WeakHashMap as the basis of this implementation and preserve the same semantics.- See Also:
