Interface LongPrimitiveIterator

All Superinterfaces:

Iterator<Long>, SkippingIterator<Long>

All Known Implementing Classes:

AbstractLongPrimitiveIterator, LongPrimitiveArrayIterator, SamplingLongPrimitiveIterator

public interface LongPrimitiveIterator
extends SkippingIterator<Long>

Adds notion of iterating over long primitives in the style of an Iterator -- as opposed to iterating over Long. Implementations of this interface however also implement Iterator and Iterable over Long for convenience.
