Int2LongMap
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<Int2LongMap.Entry> 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:
