How to remove all event listeners from a display object?

Question

Is there a way to determine which event listeners are registered with a display object? I want to remove all event listeners from a display object so that I can assign new ones

back2dos has mentioned the approach you should use, what i did was extend the movieclip class and implemented all kinds of functions that i use on daily basis but are not part of the movieclip class. including the override for the addEventListener class

protected var listeners : Dictionary    = new Dictionary();
override public function addEventListener( type : String, listener : Function, useCapture : Boolean = false, priority : int = 0, useWeakReference : Boolean = true) : void
{
        var key : Object = {type:type,useCapture:useCapture};
        if( listeners[ key ] ) {
                removeEventListener( type, listeners[ key ], useCapture );
                listeners[ key ] = null;
        }
        listeners[ key ] = listener;

        super.addEventListener( type, listener, useCapture, priority, useWeakReference );
}
protected function removeListeners () : void
{
        try
        {
            for (var key:Object in listeners) {
                    removeEventListener( key.type, listeners[ key ], key.useCapture );
                        listeners[ key ] = null;
            }
        }catch(e:Error){}
}
