# Class AbstractListIteratorDecorator<E>

java.lang.Object
org.apache.commons.collections4.iterators.AbstractListIteratorDecorator<E>

Type Parameters:
  `E` - the type of elements in this iterator.

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

Direct Known Subclasses:
  `PredicatedList.PredicatedListIterator`, `TransformedList.TransformedListIterator`

public class AbstractListIteratorDecorator<E> extends Object implements ListIterator<E>
Provides basic behavior for decorating a list iterator with extra functionality.

All methods are forwarded to the decorated list iterator.
