    Default call super method outside of 'this'

    Hi,
    i would like to call a method defined in an ancestor class from a descendant class but outside of the scope of 'this'. The code below shows clearly what i need. The line with "INVALID!" remark shows the prolematic point. Is that call possible in any way?
    Thanks.
    public class Base {
     private String name;
     
     public String getName() {
      return name; // it is for example only, it is very complex in real app
     }
     
    }
    public class Sub extends Base {
     private Sub previous; // implements an one way list
     
     @Override
     public String getName() {
      Sub sub = this;
      while (sub.previous!=null) sub = sub.previous; // name is stored only in the first object
      return sub.super.getName(); // INVALID!
     }
     
    }

    Default Re: call super method outside of 'this'

    Why not return super.getName()? In this context there is no need for 'this'. If however, you want a reference to an object in another client and call the parent function rather than the inherited implementation, as far as I know you cannot...and I'd recommend re-evaluating the design should you find the need to do so.
