public static class Reference2BooleanMaps.Singleton<K>
- extends Reference2BooleanFunctions.Singleton<K>
- implements Reference2BooleanMap<K>, Serializable, Cloneable
An immutable class representing a type-specific singleton map.
This class may be useful to implement your own in case you subclass
a type-specific map.

reference2BooleanEntrySet
public ObjectSet<Reference2BooleanMap.Entry<K>> reference2BooleanEntrySet()
- Description copied from interface:
Reference2BooleanMap
- Returns a type-specific set view of the mappings contained in this map.
This method is necessary because there is no inheritance along
type parameters: it is thus impossible to strengthen Reference2BooleanMap.entrySet()
so that it returns an ObjectSet
of objects of type Reference2BooleanMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
- Specified by:
reference2BooleanEntrySet
in interface Reference2BooleanMap<K>
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Reference2BooleanMap.entrySet()

- Description copied from interface:
Reference2BooleanMap
- Returns a set view of the keys contained in this map.
Note that this specification strengthens the one given in Map.keySet()
.
- Specified by:
keySet
in interface Reference2BooleanMap<K>
- Specified by:
keySet
in interface Map<K,Boolean>
- Returns:

values
public BooleanCollection values()
- Description copied from interface:
Reference2BooleanMap

in interface Reference2BooleanMap<K>
- Specified by:
