How to make an outer class inherited from an inner class?

Question

How can I make something like this work:

class Outer {
  int some_member;

  abstract class InnerBase {
    abstract void method();
  }
}

class OuterExtends         


        

Answer 1

The problem here is that the synthetic field which links InnerBase to Outer is a private field. Thus, we can only access the outer object from within InnerBase, or if some method or field there provides a reference to the same object.
