public static class Char2CharMaps.EmptyMap
- extends Char2CharFunctions.EmptyFunction
- implements Char2CharMap, Serializable, Cloneable
An immutable class representing an empty type-specific map.
This class may be useful to implement your own in case you subclass
a type-specific map.

containsValue
public boolean containsValue(char v)
- Specified by:
containsValue
in interface Char2CharMap
- See Also:
Map.containsValue(Object)
putAll
public void putAll(Map<? extends Character,? extends Character> m)
- Specified by:
putAll
in interface Map<Character,Character>
char2CharEntrySet
public ObjectSet<Char2CharMap.Entry> char2CharEntrySet()
- Description copied from interface:
Char2CharMap
- 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 Char2CharMap.entrySet()
so that it returns an ObjectSet
of objects of type Char2CharMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
- Specified by:
char2CharEntrySet
in interface Char2CharMap
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Char2CharMap.entrySet()

public CharSet keySet()
- Description copied from interface:
Char2CharMap
- 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 Char2CharMap
- Specified by:
keySet
in interface Map<Character,Character>
- Returns:
- a set view of the keys contained in this map.
- See Also:

values
public CharCollection values()
- Description copied from interface:
Char2CharMap
- Returns a set view of the values contained in this map.
Note that this specification strengthens the one given in Map.values()
.
- Specified by:
values
in interface Char2CharMap
- Specified by:
values
in interface Map<Character,Character>
- Returns:
- a set view of the values contained in this map.
