All Implemented Interfaces:

BidirectionalIterator<Long>, LongBidirectionalIterator, LongIterator, ObjectBidirectionalIterator<Long>, ObjectIterator<Long>, Iterator<Long>

Enclosing class:

AbstractLong2LongSortedMap

protected static class AbstractLong2LongSortedMap.KeySetIterator
extends AbstractLongBidirectionalIterator

A wrapper exhibiting a map iterator as an iterator on keys.

To provide an iterator on keys, just create an instance of this class using the corresponding iterator on entries.
