Interface Long2BooleanMap.FastEntrySet

All Superinterfaces:

Collection<Long2BooleanMap.Entry>, Iterable<Long2BooleanMap.Entry>, ObjectCollection<Long2BooleanMap.Entry>, ObjectIterable<Long2BooleanMap.Entry>, ObjectSet<Long2BooleanMap.Entry>, Set<Long2BooleanMap.Entry>

All Known Subinterfaces:

Long2BooleanSortedMap.FastSortedEntrySet

Enclosing interface:

Long2BooleanMap

public static interface Long2BooleanMap.FastEntrySet
extends ObjectSet<Long2BooleanMap.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).
