public static class Double2CharMaps.Singleton
- extends Double2CharFunctions.Singleton
- implements Double2CharMap, 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.

public boolean containsValue(Object ov)
- Specified by:

in interface Map<Double,Character>
putAll
public void putAll(Map<? extends Double,? extends Character> m)
- Specified by:

in interface Map<Double,Character>
double2CharEntrySet
public ObjectSet<Double2CharMap.Entry> double2CharEntrySet()
- Description copied from interface:
Double2CharMap
- 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 Double2CharMap.entrySet()
so that it returns an ObjectSet
of objects of type Double2CharMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
- Specified by:
double2CharEntrySet
in interface Double2CharMap
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Double2CharMap.entrySet()

Note that this specification strengthens the one given in Map.keySet()
.
- Specified by:

in interface Double2CharMap
- Specified by:
keySet
in interface Map<Double,Character>
- Returns:
