Interface Long2LongSortedMap.FastSortedEntrySet

All Superinterfaces:

java.util.Collection<Long2LongMap.Entry>, java.lang.Iterable<Long2LongMap.Entry>, Long2LongMap.FastEntrySet, ObjectCollection<Long2LongMap.Entry>, ObjectIterable<Long2LongMap.Entry>, ObjectSet<Long2LongMap.Entry>, ObjectSortedSet<Long2LongMap.Entry>, java.util.Set<Long2LongMap.Entry>, java.util.SortedSet<Long2LongMap.Entry>

Enclosing interface:

Long2LongSortedMap

public static interface Long2LongSortedMap.FastSortedEntrySet
extends ObjectSortedSet<Long2LongMap.Entry>, Long2LongMap.FastEntrySet

A sorted 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 entry objects. Some fastutil maps might return entry set objects of type FastSortedEntrySet: 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

ObjectBidirectionalIterator<Long2LongMap.Entry>

fastIterator(Long2LongMap.Entry from) Returns a fast iterator over this sorted entry set; the iterator might return always the same entry object, suitably mutated.
