public static class Char2DoubleMaps.EmptyMap
- extends Char2DoubleFunctions.EmptyFunction
- implements Char2DoubleMap, 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(double v)
- Specified by:
containsValue
in interface Char2DoubleMap
- See Also:
Map.containsValue(Object)
putAll
public void putAll(Map<? extends Character,? extends Double> m)
- Specified by:
putAll
in interface Map<Character,Double>
char2DoubleEntrySet
public ObjectSet<Char2DoubleMap.Entry> char2DoubleEntrySet()
- Description copied from interface:
Char2DoubleMap
- 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 Char2DoubleMap.entrySet()
so that it returns an ObjectSet
of objects of type Char2DoubleMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
- Specified by:
char2DoubleEntrySet
in interface Char2DoubleMap
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Char2DoubleMap.entrySet()

Char2DoubleMap
- 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 Char2DoubleMap
- Specified by:
keySet
in interface Map<Character,Double>
- Returns:
- a set view of the keys contained in this map.
- See Also:

values
public DoubleCollection values()
- Description copied from interface:
Char2DoubleMap
- 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 Char2DoubleMap
- Specified by:
values
in interface Map<Character,Double>
- Returns:
- a set view of the values contained in this map.
