Interface PeekableIntIterator

All Superinterfaces:

Cloneable, IntIterator

All Known Implementing Classes:

BufferIntIteratorFlyweight, IntIteratorFlyweight

public interface PeekableIntIterator
extends IntIterator

Simple extension to the IntIterator interface. It allows you to "skip" values using the advanceIfNeeded method, and to look at the value without advancing (peekNext).

Method Summary

Modifier and Type	Method and Description
void	advanceIfNeeded(int minval) If needed, advance as long as the next value is smaller than minval
PeekableIntIterator	clone() Creates a copy of the iterator.
int	peekNext() Look at the next value without advancing
