public static interface Float2ReferenceMap.FastEntrySet<V>
extends ObjectSet<Float2ReferenceMap.Entry<V>>
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), and fastForEach(Consumer)
will apply
the provided consumer to all elements of the entry set, which might be represented
always by the same entry (of course, mutated).

fastIterator
ObjectIterator<Float2ReferenceMap.Entry<V>> fastIterator()Returns a fast iterator over this entry set; the iterator might return always the same entry instance, suitably mutated.- Returns:
- a fast iterator over this entry set; the iterator might return always the same
Map.Entry
instance, suitably mutated.
-
fastForEach
Iterates quickly over this entry set; the iteration might happen always on the same entry instance, suitably mutated.This default implementation just delegates to
Iterable.forEach(Consumer)
.- Parameters:
consumer
- a consumer that will by applied to the entries of this set; the entries might be represented by the same entry instance, suitably mutated.- Since:
