Class ReverseListIterator<E>

java.lang.Object
  net.cscott.jutil.ReverseListIterator<E>

All Implemented Interfaces:

Iterator<E>, ListIterator<E>

public class ReverseListIterator<E>
extends Object
implements 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.
