Method Summary

Methods

Modifier and Type	Method and Description
E[]	getChunk() The elements in the current chunk -or- null iff there are NO elements in the chunk.

boolean	isExhausted() true iff the iterator will not return any more chunks.

Method Detail

isExhausted

boolean isExhausted()

true iff the iterator will not return any more chunks.

getChunk

E[] getChunk()

The elements in the current chunk -or- null iff there are NO elements in the chunk.

getKeyOrder

IKeyOrder<E> getKeyOrder()

The natural sort orded of the elements in this chunk -or- null if the elements are not in any known order.

Note: The returned value should be the same each time for a given source iterator. It is put here so that we can avoid an RMI for this property and the expense of serializing the value with each chunk.
