public static class Object2CharMaps.Singleton<K> extends Object2CharFunctions.Singleton<K> implements Object2CharMap<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.

containsValue
public boolean containsValue(char v)Description copied from interface:Object2CharMap
Returnstrue
if this map maps one or more keys to the specified value.- Specified by:
containsValue
in interfaceObject2CharMap<K>
- See Also:
Map.containsValue(Object)
-
containsValue
Deprecated.Please use the corresponding type-specific method instead.- Specified by:
containsValue

putAll
-
object2CharEntrySet
Description copied from interface:Object2CharMap
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
Map.entrySet()
so that it returns anObjectSet
of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).- Specified by:
object2CharEntrySet
in interfaceObject2CharMap<K>
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
entrySet
Deprecated.Please use the corresponding type-specific method instead.Returns a set view of the mappings contained in this map.- Specified by:
entrySet
in interfaceMap<K,Character>
- Specified by:
entrySet
in interfaceObject2CharMap<K>
- Returns:
- a set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
Description copied from interface:Object2CharMap
- Specified by:
keySet
in interfaceMap<K,Character>
- Specified by:
keySet
in interfaceObject2CharMap<K>
- Returns:
- a set view of the keys contained in this map.
- See Also:
