从某些refreence变量的方法（不是该类的子级）中了解类的方式是什么

Question

What can be the way to know the class name "Abc" from where the function of a reference variable "def" has been called ? Except these two ways :

1) Adding the def as a child of Abc

2) Injecting reference of Abc into Def prior or during the function call.

here is the class Abc :

public class Abc
{
   var def:Def ; 
   public function Abc()
   {

         def = new Def();
        def.myfun() ;
   }



}


public class Def 
{

  public function Def()
  {
  }
  public function myfun():void 
  {

     // Code to know, this function has been called from class named Abc ; 
  }

}

Answer 1

No, that is not possible. It is also useless. The closest thing you can do to what you want is to get a reference to the function calling Abc.myfun() via arguments.callee :

public function myfun():void
{
    var callee:Function = arguments.callee;
}

Though this won't have any useful information attached like the function or class name.

Answer 2

Maybe like this:

public class Abc
{
   var def:Def;

   public function Abc()
   {
        def = new Def();
        def.myfun( true ) ;
   }
}


public class Def 
{
  public function Def()
  {
  }

  public function myfun(fromAbc:Boolean=false):void 
  {
    if( fromAbc == true )
    {
        // Code to know, this function has been called from class named Abc ;
    }
  }
}

Answer 3

You could get the information from the stacktrace, but that would only work in debug mode.

There isn't really a clean way to do it, because you shouldn't need to do it. If you explained a bit more about your situation / goal there is probably a simple answer (requiring a small redesign) that will help you. (cant post comments)
