Lock

A Lock allows blocking execution until it has been unlocked. It keeps track of how often release has been called, and blocks exactly as many wait calls.

The order of the release and wait calls is irrelevant. That is, a Lock can be released before anyone waits for it. In that case, the wait call will execute immediately.

Usage example:

var lock = new Lock();
var elements = [1, 2, 3];
for (element in elements) {
// Create one thread per element
new Thread(function() {
trace(element);
Sys.sleep(1);
// Release once per thread = 3 times
lock.release();
});
}
for (_ in elements) {
// Wait 3 times
lock.wait();
}
trace("All threads finished");
