Hi all,
Is there any way in which I get the caller function name. As in :

class Aclass{

    instanceB:Bclass;
   function a(){
      instanceB.b(this)
   }

}

class Bclass{
     function b(Obj){
        // How to trace function name and class name
      }
}


I have traced out class name by getFullyQualifiedClassName(Obj) but how to
trace function name ???

Please somebody guide me .. its very important for me.

Regards
