public static class Reference2ReferenceMaps.Singleton<K,V> extends Reference2ReferenceFunctions.Singleton<K,V> implements Reference2ReferenceMap<K,V>, java.io.Serializable, java.lang.Cloneable
This class may be useful to implement your own in case you subclass a type-specific map.

public ObjectSet<Reference2ReferenceMap.Entry<K,V>> reference2ReferenceEntrySet()
Reference2ReferenceMap
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Reference2ReferenceMap.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).
