public static class Reference2ReferenceSortedMaps.Singleton<K,V> extends Reference2ReferenceMaps.Singleton<K,V> implements Reference2ReferenceSortedMap<K,V>, Serializable, Cloneable
This class may be useful to implement your own in case you subclass a type-specific sorted map.

entrySet()
Returns a set view of the mappings contained in this map.
|
K |
firstKey() |

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 objects of type Map.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
