Resolving Ambiguity when Accessing Parent Class from Anonymous Class

Question

I recently ran into something like this...

public final class Foo<T>
implements Iterable<T> {

    //...

    public void remove(T t) { /* banana banana banana */ }

    //...

    public Iterator<T> Iterator {
        return new Iterator<T>() {

            //...

            @Override
            public void remove(T t) {
                // here, 'this' references our anonymous class...
                // 'remove' references this method...
                // so how can we access Foo's remove method?           
            }

            //...

        };
    }
}

Is there any way to do what I'm trying to while keeping this as an anonymous class? Or do we have to use an inner class or something else?

To access remove in the enclosing class, you can use

...
    @Override
    public void remove(T t) {
        Foo.this.remove(t);         
    }
...

Foo.this.remove(t) will do the trick for you.
