public interface LazyIntIterator

A lazy iterator over the integers.

An instance of this class represent a (skippable) iterator over the integers. The iterator is exhausted when an implementation-dependent special marker is returned. This fully lazy architecture halves the number of method calls w.r.t. Java's eager iterators.

Method Summary

int	nextInt() The next integer returned by this iterator, or the special marker if this iterator is exhausted.
int	skip(int n) Skips a given number of elements.

Method Detail

nextInt

int nextInt()

The next integer returned by this iterator, or the special marker if this iterator is exhausted.

Returns:

next integer returned by this iterator, or the special marker if this iterator is exhausted.

skip

int skip(int n)

Skips a given number of elements.

Parameters:

n - the number of elements to skip.

Returns:

the number of elements actually skipped (which might be less than n if this iterator is exhausted).
