i have class A, then class B which entends class A, then class C which entends class B.  
now in class A there are couple of empty methods currently defined as protected.  
in class B these methods are also empty //i dont know how to make this exactly, they should obvioulsy be here as well because… -\>  
then in class C i want to override these methods and actually do something in them.

so how do i stretch these empty methods from class A to class C?  
don tell me this has to go like this? 😃

```auto
class A:
protected function rollOverHandler(e:MouseEvent):void {}
class B:
override protected function rollOverHandler(e:MouseEvent):void {
     super.rollOverHandler();//do i need this because nothing is happening above?
}
class C:
override protected function rollOverHandler(e:MouseEvent):void {
     do something here...
}

```
