systemManager.removeEventListener(“mouseUp”, mouseUpHandler);
2. Use of weak reference listeners
override protected function mouseDownHandler(…):void {
systemManager.addEventListener(“mouseUp”, mouseUpHandler, false, 0, true);
These do not block garbage collection(generally do not cause memory leaks):
Weak References
Self References
References to Child Objects
weak reference event listener e.g.
