Class Synchronizer

Implemented Interfaces:
Callable, Function, Scriptable

public class Synchronizer
extends Delegator

This class provides support for implementing Java-style synchronized methods in Javascript. Synchronized functions are created from ordinary Javascript functions by the Synchronizer constructor, e.g. new Packages.org.mozilla.javascript.Synchronizer(fun). The resulting object is a function that establishes an exclusive lock on the this object of its invocation. The Rhino shell provides a short-cut for the creation of synchronized methods: sync(fun) has the same effect as calling the above constructor.
