public static class Long2ReferenceMaps.EmptyMap<V> extends Long2ReferenceFunctions.EmptyFunction<V> implements Long2ReferenceMap<V>, Serializable, Cloneable
This class may be useful to implement your own in case you subclass a type-specific map.

Long2ReferenceMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Long2ReferenceMap.entrySet()
so that it returns an ObjectSet
of objects of type Map.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
