public static interface Reference2IntMap.FastEntrySet<K>
- extends ObjectSet<Reference2IntMap.Entry<K>>
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 Reference2IntMap.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).

fastIterator
ObjectIterator<Reference2IntMap.Entry<K>> fastIterator()
- Returns a fast iterator over this entry set; the iterator might return always the same entry object, suitably mutated.
- Returns:
- a fast iterator over this entry set; the iterator might return always the same
Reference2IntMap.Entry
object, suitably mutated.
