public Class ReverseListIterator<T>

extends Object
implements Iterator<T>
Class Inheritance
All Implemented Interfaces
java.util.Iterator
Imports
java.util.Iterator, .List, .ListIterator

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.

ReverseListIterator(List<T>
the list to iterate over in reverse

Constructs a new ReverseListIterator for the provided list.

Method Summary

Modifier and TypeMethod and Description
public boolean
hasNext()

Implements java.util.Iterator.hasNext.

Returns true if the iteration has more elements.
public T
next()

Implements java.util.Iterator.next.

Returns the next element in the iteration.
public void
remove()

Overrides default java.util.Iterator.remove.

Method Detail

hasNextback to summary
public boolean hasNext()

Implements java.util.Iterator.hasNext.

Doc from java.util.Iterator.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.)

Returns:boolean

true if the iteration has more elements

nextback to summary
public T next()

Implements java.util.Iterator.next.

Doc from java.util.Iterator.next.

Returns the next element in the iteration.

Returns:T

the next element in the iteration

removeback to summary
public void remove()

Overrides default java.util.Iterator.remove.

Doc from java.util.Iterator.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.
