hasEventListener

the code goes like this:

if(imageLoader.hasEventListener(Event.ENTER_FRAME)){
            trace("1");
 }

and **not **like this:

if(imageLoader.hasEventListener(Event.ENTER_FRAME**, someFunction**)){
            trace("1");
 }

if(imageLoader.hasEventListener(Event.ENTER_FRAME**, someOtherFunction**)){
            trace("2");
 }

so how can I check for multiple same listeners?
what if I have few same type listeners registered with different functions and I wan to do different actions?
