Interface ObjectBidirectionalIterator<T>

Type Parameters:

T - the type of elements maintained by this Collection

All Superinterfaces:

java.util.Iterator<T>, ObjectIterator<T>

All Known Subinterfaces:

BooleanBidirectionalIterator, BooleanListIterator, ByteBidirectionalIterator, ByteListIterator, CharBidirectionalIterator, CharListIterator, DoubleBidirectionalIterator, DoubleListIterator, FloatBidirectionalIterator, FloatListIterator, IntBidirectionalIterator, IntListIterator, LongBidirectionalIterator, LongListIterator, ObjectListIterator<T>, ShortBidirectionalIterator, ShortListIterator

public interface ObjectBidirectionalIterator<T>
extends ObjectIterator<T>

This is a basically a ListIterator without the index functions. Allowing to have a simple Bidirectional Iterator without having to keep track of the Iteration index.

Method Summary

Method Detail

hasPrevious

boolean hasPrevious()

Returns true if the Iterator has a Previous element

Returns:

true if the Iterator has a Previous element

previous

T previous()

Returns the Previous element of the iterator.

Returns:

the Previous element of the iterator.

Throws:

java.util.NoSuchElementException - if the iteration has no more elements

back

default int back(int amount)

Reverses the Given amount of elements if possible. A Optimization function to reverse elements faster if the implementation allows it.

Parameters:

amount - the amount of elements that should be reversed

Returns:

the amount of elements that were reversed
