public static class Object2ReferenceMaps.Singleton<K,V> extends Object2ReferenceFunctions.Singleton<K,V> implements Object2ReferenceMap<K,V>, Serializable, Cloneable
This class may be useful to implement your own in case you subclass a type-specific map.

Object2ReferenceMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Object2ReferenceMap.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).
