public abstract class ForwardingIterator<T>

protected abstract Iterator<T> delegate()
- Description copied from class:
ForwardingObject
- Returns the backing delegate instance that methods are forwarded to.
Abstract subclasses generally override the
ForwardingObject
method
with an abstract method that has a more specific return type, such as
ForwardingSet.delegate()
. Concrete subclasses override this method to
supply the instance being decorated.
