Re: Synchronized functions

[Tal Liron]

Also, wouldn't this shorter version work?

function synchronize(fn) {
          var lock = new java.util.concurrent.locks.ReentrantLock()
          return function() {
              lock.lock()
              try {
                  return fn.apply(this, arguments)
              }
              finally {
                  lock.unlock()
              }
          }
}

Thanks!

Would it be possible to add this to mozilla_compat.js so that "new org.mozilla.javascript.Synchronizer(myFunction)" would work?

There is a 'sync' function in a demo application (jconsole script plugin). This may be of use.

    var sync = function(func, obj) {
        if (arguments.length < 1 || arguments.length > 2 ) {
            throw "sync(function [,object]) parameter count mismatch";
        }

        var syncobj = (arguments.length == 2 ? obj : this);

        if (!syncobj._syncLock) {
            syncobj._syncLock = new Lock();
        }

        return function() {
            syncobj._syncLock.lock();
            try {
                func.apply(null, arguments);
            } finally {

How does one create synchronized functions in Nashorn?

Rhino has this facility:

function myFunction() { ... }
myFunction = new org.mozilla.javascript.Synchronizer(myFunction)
