 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:

Method Detail- 
getClassNamepublic java.lang.String getClassName() Description copied from class:ScriptableObjectReturn the name of the class.This is typically the same name as the constructor. Classes extending ScriptableObject must implement this abstract method. - Specified by:
