- All Implemented Interfaces:
- 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.
