public static class Reference2LongMaps.EmptyMap<K> extends Reference2LongFunctions.EmptyFunction<K> implements Reference2LongMap<K>, Serializable, Cloneable
This class may be useful to implement your own in case you subclass a type-specific map.

Reference2LongMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Reference2LongMap.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).
