All Implemented Interfaces:
  Iterator<E>, ListIterator<E>

    @GwtCompatible
    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.

Constructor Detail

### ForwardingListIterator

    protected ForwardingListIterator()

  Constructor for use by subclasses.

Method Detail

### 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.

  Specified by:
    `delegate` in class `ForwardingIterator<E>`

### add
