public interface IntBidirectionalIterator

extends IntIterator, BidirectionalIterator

A type-specific bidirectional iterator; provides an additional method to reduce type juggling, and the possibility to skip elements backwards.

BidirectionalIterator

Method Summary

int	back(int n) Moves back for the given number of elements.
int	previousInt() Returns the previous element as a primitive type.

Method Detail

previousInt

public int previousInt()

Returns the previous element as a primitive type.

Returns:

the previous element from the collection.

See Also:

ListIterator.previous()

back

public int back(int n)

Moves back for the given number of elements.

The effect of this call is exactly the same as that of calling BidirectionalIterator.previous() for n times (possibly stopping if BidirectionalIterator.hasPrevious() becomes false).

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.

Iterator.next()
