Access “this” from Java anonymous class
Given the following code:
public interface Selectable
public void select();
public class Container implements Selectable
public void select()
...
public void createAnonymousClass()
Selectable s = new Selectable()
public void select()
//see comment below.
;
I want to access Container.select() from within my anonymous class' select() method. However, this.select() would again call the anonymous class' select() method.
My suggestion would be:
Introduce a field into Container, e.g.
private Container self = this;
Now I can access Container.select() by calling self.select() from within the anonymous class.
Is this a reasonable way? Or are there any better ways?

It should be noted that you have to specify ExactlyContainerclass here. Any of its ancestors won't be accepted.

You can write Container.this.select() to distinct from the inner class !
