我有带有方法的类事件管理器:
public function addEvent(obj:IEventDispatcher, event:String, listener:Function,
useCapture:Boolean = false, priority:int = 0,
useWeakReference:Boolean = false):void
{
obj.addEventListener(event, listener, useCapture, priority, useWeakReference);
[here event is pushed in my stack]
}
我想这样做:
public class CustomClass extends Sprite
{
public override function addEventListener(type:String, listener:Function,
useCapture:Boolean = false, priority:int = 0,
useWeakReference:Boolean = false):void
{
eventManager.addEvent(this, type, listener, useCapture, priority, useWeakReference);
}
}
但在结果调用堆栈中是:
customClass.addEventListener ->
eventManager.addEvent ->
customClass.addEventListener ->
eventManager.addEvent ->
customClass.addEventListener ->
...
等等...因为我在eventManager.addEvent中调用obj.addEventListener
也许你能给我解决这个问题的方法吗?
您创建了一个递归循环,因为您在事件管理器中调用了对象上的 addEventlistener 函数,该函数调用事件管理器等...您可能打算做的是只在事件管理器中存储对对象和参数的引用,而不是从那里实际调用 addEventlistener-function。
