AS3 reflection. How do I know if a method has been canceled?

Question

Can I use AS3 reflection to find out if the method has been overridden?

I need a method like:

protected function isOverriden(methodName:string) : bool
{
    //magic here!
    //...

    return awesomeLocalVariable;
}

So, I pass the method name as a string, and the isOverridden method returns true only if and only if the object has a method of this name and is overridden from its original implementation.

Any idea on how to encode the magic there?

Thanks.

Edit: As requested, the context of the problem:

AS3. "" , , . (onClick, onUpdate, onShapeCollision ..). Component, , , ().

:

    public class CTrace extends ScriptComponent
    {
            public override function onClick(event:MouseEvent = null):void
            {
                    trace(Owner.Id);
            }
    }

onClick MouseEvent.CLICK, .

overriden = (this[stringNameOfMethod] instanceOf Function && super[stringNameOfMethod] instanceOf Function);
