public abstract class ForwardingListIterator<E>
- extends ForwardingIterator<E>
- implements ListIterator<E>
A list iterator which forwards all its method calls to another list
iterator. Subclasses should override one or more methods to modify the
behavior of the backing iterator as desired per the decorator pattern.

ForwardingListIterator
protected ForwardingListIterator()
- Constructor for use by subclasses.
delegate
protected abstract ListIterator<E> delegate()
- Description copied from class:
ForwardingObject
- Returns the backing delegate instance that methods are forwarded to.
Abstract subclasses generally override this 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.
