public static class Reference2IntMaps.EmptyMap<K> extends Reference2IntFunctions.EmptyFunction<K> implements Reference2IntMap<K>, Serializable, Cloneable
This class may be useful to implement your own in case you subclass a type-specific map.

Reference2IntMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Reference2IntMap.entrySet()
so that it returns an ObjectSet
of type-specific entries (the latter makes it possible to
access keys and values with type-specific methods).
