Class ReverseListIterator<E>

java.lang.Object

net.cscott.jutil.ReverseListIterator<E>

All Implemented Interfaces:

java.util.Iterator<E>, java.util.ListIterator<E>

public class ReverseListIterator<E>
extends java.lang.Object
implements java.util.ListIterator<E>

ReverseListIterator takes a List and gives you an Iterator that traverses the list in reverse order. Similar to using ReverseIterator(l.iterator()) but more efficient as it does not need to create a snapshot.
