public static class Byte2ObjectMaps.EmptyMap<V>
- extends Byte2ObjectFunctions.EmptyFunction<V>
- implements Byte2ObjectMap<V>, 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(Object v)
- Specified by:
containsValue
in interface Map<Byte,V>
putAll
public void putAll(Map<? extends Byte,? extends V> m)
- Specified by:
putAll
in interface Map<Byte,V>
byte2ObjectEntrySet
public ObjectSet<Byte2ObjectMap.Entry<V>> byte2ObjectEntrySet()
- Description copied from interface:
Byte2ObjectMap
- 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 Byte2ObjectMap.entrySet()
so that it returns an ObjectSet
of objects of type Byte2ObjectMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
- Specified by:
byte2ObjectEntrySet
in interface Byte2ObjectMap<V>
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Byte2ObjectMap.entrySet()

- Description copied from interface:
Byte2ObjectMap
- 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 Byte2ObjectMap<V>
- Specified by:
keySet
in interface Map<Byte,V>
- Returns:
- a set view of the keys contained in this map.
- See Also:

values
public ObjectCollection<V> values()
- Description copied from interface:
Byte2ObjectMap
- 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 Byte2ObjectMap<V>
- Specified by:
