Class AbstractDouble2ObjectSortedMap.KeySetIterator<V>

java.lang.Object

it.unimi.dsi.fastutil.doubles.AbstractDouble2ObjectSortedMap.KeySetIterator<V>

All Implemented Interfaces:

BidirectionalIterator<Double>, DoubleBidirectionalIterator, DoubleIterator, ObjectBidirectionalIterator<Double>, ObjectIterator<Double>, Iterator<Double>, PrimitiveIterator<Double,DoubleConsumer>, PrimitiveIterator.OfDouble

Enclosing class:

AbstractDouble2ObjectSortedMap<V>

protected static class AbstractDouble2ObjectSortedMap.KeySetIterator<V>
extends Object
implements DoubleBidirectionalIterator

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.
