it.unimi.dsi.fastutil.doubles.AbstractDouble2DoubleSortedMap.KeySetIterator

All Implemented Interfaces:

BidirectionalIterator<Double>, DoubleBidirectionalIterator, DoubleIterator, ObjectBidirectionalIterator<Double>, ObjectIterator<Double>, Iterator<Double>

Enclosing class:

AbstractDouble2DoubleSortedMap

protected static class AbstractDouble2DoubleSortedMap.KeySetIterator
extends AbstractDoubleBidirectionalIterator

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.
