java.lang.Object

it.unimi.dsi.fastutil.chars.AbstractChar2IntSortedMap.KeySetIterator

All Implemented Interfaces:

BidirectionalIterator<Character>, CharBidirectionalIterator, CharIterator, ObjectBidirectionalIterator<Character>, ObjectIterator<Character>, Iterator<Character>

Enclosing class:

AbstractChar2IntSortedMap

protected static class AbstractChar2IntSortedMap.KeySetIterator
extends Object
implements CharBidirectionalIterator

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.
