public static interface Object2ReferenceSortedMap.FastSortedEntrySet<K,V>
extends ObjectSortedSet<Object2ReferenceMap.Entry<K,V>>, Object2ReferenceMap.FastEntrySet<K,V>
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).
