Interface Double2IntMap.FastEntrySet

All Superinterfaces:

Collection<Double2IntMap.Entry>, Iterable<Double2IntMap.Entry>, ObjectCollection<Double2IntMap.Entry>, ObjectIterable<Double2IntMap.Entry>, ObjectSet<Double2IntMap.Entry>, Set<Double2IntMap.Entry>

All Known Subinterfaces:

Enclosing interface:

Double2IntMap

public static interface Double2IntMap.FastEntrySet
extends ObjectSet<Double2IntMap.Entry>

An entry set providing fast iteration.

In some cases (e.g., hash-based classes) iteration over an entry set requires the creation of a large number of Map.Entry objects. Some fastutil maps might return entry set objects of type FastEntrySet: in this case, fastIterator() will return an iterator that is guaranteed not to create a large number of objects, possibly by returning always the same entry (of course, mutated).

Method Summary

Modifier and Type	Method and Description
ObjectIterator<Double2IntMap.Entry>	fastIterator() Returns a fast iterator over this entry set; the iterator might return always the same entry object, suitably mutated.
