containsValue
public boolean containsValue(boolean v)
Description copied from interface:Char2BooleanMap
Returnstrue
if this map maps one or more keys to the specified value.- Specified by:
containsValue
in interfaceChar2BooleanMap
- See Also:
Map.containsValue(Object)
-
containsValue
@Deprecated public boolean containsValue(Object ov)
Deprecated.Please use the corresponding type-specific method instead.- Specified by:
containsValue
in interfaceChar2BooleanMap
- Specified by:
containsValue
in interfaceMap<Character,Boolean>
-
char2BooleanEntrySet
public ObjectSet<Char2BooleanMap.Entry> char2BooleanEntrySet()
Description copied from interface:Char2BooleanMap
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:
char2BooleanEntrySet
in interfaceChar2BooleanMap
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
public CharSet keySet()
Description copied from interface:Char2BooleanMap
Note that this specification strengthens the one given in
Map.keySet()
.- Specified by:
keySet
in interfaceChar2BooleanMap
- Specified by:
keySet
in interfaceMap<Character,Boolean>
- Returns:
- a set view of the keys contained in this map.
- See Also:
Map.keySet()
-
values
public BooleanCollection values()
Description copied from interface:Char2BooleanMap
Note that this specification strengthens the one given in
Map.values()
.- Specified by:
values
in interfaceChar2BooleanMap
- Specified by:
values
in interfaceMap<Character,Boolean>
- Returns:
- a set view of the values contained in this map.
- See Also:
Map.values()
