All Implemented Interfaces:

Serializable, Iterator<E>, ListIterator<E>

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 change or add behavior of the backing iterator as desired per the decorator pattern.

ForwardingListIterator

protected ForwardingListIterator(ListIterator<E> delegate)

Method Detail

delegate

protected ListIterator<E> delegate()

Description copied from class: ForwardingObject

Returns the backing delegate object. This method should be overridden to specify the correct return type. For example:

  @SuppressWarnings("unchecked")
  @Override protected Foo delegate() {
    return (Foo) super.delegate();
  }

This method should always return the same delegate instance that was passed to the constructor.
