Class NativeWeakSet

java.lang.Object

org.mozilla.javascript.ScriptableObject

org.mozilla.javascript.IdScriptableObject

org.mozilla.javascript.NativeWeakSet

All Implemented Interfaces:

java.io.Serializable, ConstProperties, DebuggableObject, IdFunctionCall, Scriptable, SymbolScriptable

public class NativeWeakSet
extends IdScriptableObject

This is an implementation of the ES6 WeakSet class. It is very similar to NativeWeakMap, with the exception being that it doesn't store any values. Java will GC the key only when there is no longer any reference to it other than the weak reference. That means that it is important that the "value" that we put in the WeakHashMap here is not one that contains the key.

Method Detail

getClassName

public java.lang.String getClassName()

Description copied from class: ScriptableObject

Return the name of the class. This is typically the same name as the constructor. Classes extending ScriptableObject must implement this abstract method.
