Remove all ENTER_FRAME listeners - actionscript-3

Question

Is there a way to remove ALL ENTER_FRAME event listeners at once?

Answer 1

Only if you've been keeping careful track of your listeners. There is no "removeAll" type functionality for event listeners, so it helps to collect your listeners in an easy-to-manage place.

Answer 2

An option is to create a class that handles adding event listeners to IEventDispatcher objects, registering those objects and removing all events listeners at the same time. The following is a example I quickly made to demonstrate this:
EventListeners.as:
package
{
import flash.events.Event;
import flash.events.IEventDispatcher;
import flash.utils.Dictionary;
public class EventListeners
{
private var _objectDictionaries:Vector.<Dictionary>;
public function EventListeners()
{
init();
}// end function
public function addEventListener(object:IEventDispatcher,
type:String,
listener:Function,
useCapture:Boolean = false,
priority:int = 0,
useWeakReference:Boolean = false)
{
object.addEventListener(type, listener, useCapture, priority, useWeakReference);
var objectDictionary:Dictionary = new Dictionary();
objectDictionary["object"] = object;
objectDictionary["type"] = type;
objectDictionary["listener"] = listener;
objectDictionary["useCapture"] = useCapture;
_objectDictionaries.push(objectDictionary);
}// end function
public function removeAll():void
{
for each(var objectDictionary:Dictionary in _objectDictionaries)
{
var object:IEventDispatcher = objectDictionary["object"] as IEventDispatcher;
var type:String = objectDictionary["type"] as String;
var listener:Function = objectDictionary["listener"] as Function;
var useCapture:Boolean = objectDictionary["useCapture"] as Boolean;
object.removeEventListener(type, listener, useCapture);
}// end for
init();
}// end function
private function init():void
{
_objectDictionaries = new Vector.<Dictionary>();
}// end function
}// end class
}// end package
Main.as:
package
{
import flash.display.Sprite;
import flash.events.Event;
public class Main extends Sprite
{
private var _eventListeners:EventListeners;
private var _sprite1:Sprite;
private var _sprite2:Sprite;
public function Main()
{
init();
}// end function
public function init():void
{
_eventListeners = new EventListeners();
_sprite1 = new Sprite();
_sprite2 = new Sprite();
_eventListeners.addEventListener(_sprite1, Event.ENTER_FRAME, enterFrameHandler);
_eventListeners.addEventListener(_sprite2, Event.ADDED_TO_STAGE, addedToStageHandler);
trace("_sprite1.hasEventListener = " + _sprite1.hasEventListener(Event.ENTER_FRAME));
trace("_sprite2.hasEventListener = " + _sprite2.hasEventListener(Event.ADDED_TO_STAGE));
_eventListeners.removeAll();
trace("\n_eventListeners.removeAll() invoked\n");
trace("_sprite1.hasEventListener = " + _sprite1.hasEventListener(Event.ENTER_FRAME));
trace("_sprite2.hasEventListener = " + _sprite2.hasEventListener(Event.ADDED_TO_STAGE));
}// end function
private function enterFrameHandler(e:Event):void {};
private function addedToStageHandler(e:Event):void {};
}// end class
}// end package
The output from running this example is the following:
_sprite1.hasEventListener = true
_sprite2.hasEventListener = true
_eventListeners.removeAll() invoked
_sprite1.hasEventListener = false
_sprite2.hasEventListener = false
