public class ReverseListIterator<T>
extends Object
implements Iterator A reverse iterator over a list. Utilizes the ListIterator
obtained from the provided List and converts it to an
Iterator that efficiently traverses the List in
reverse. The fail-fast semantics of this iterator are the same as the
semantics of the underlying ListIterator.

public boolean |
hasNext()Returns true if the iteration has more elements.
(In other words, returns true if next would
return an element rather than throwing an exception.)
|
|
public T |
next()Returns the next element in the iteration.
|
|
public void |
remove()Removes from the underlying collection the last element returned by this iterator (optional operation). This method can be called only once per call to next. The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method, unless an overriding class has specified a concurrent modification policy. The behavior of an iterator is unspecified if this method is called after a call to the forEachRemaining method.
