How can i access OuterClass through inner class instance? [duplicate]

Question

I know i can get the instance of the enclosing class using:

OuterClass.this

But i can do it only within the inner class code itself. only I have is reference of the Inner class instance withing another class code. How can i get the OuterClass instance through the inner class instance?

Answer 1

You can define a getter that returns OuterClass to callers from the outside:

public class InnerClass {
    ...
    public OuterClass getOuterInstance() {
        return OuterClass.this;
    }
}
