public static class Byte2ObjectMaps.EmptyMap<V> extends Byte2ObjectFunctions.EmptyFunction<V> implements Byte2ObjectMap<V>, java.io.Serializable, java.lang.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.

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
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:
byte2ObjectEntrySet
in interfaceByte2ObjectMap<V>
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
public ByteSet keySet()
Description copied from interface:Byte2ObjectMap
Note that this specification strengthens the one given in
Map.keySet()
.- Specified by:
keySet
in interfaceByte2ObjectMap<V>
- Specified by:
keySet
in interfacejava.util.Map<java.lang.Byte,V>
- Returns:
- a set view of the keys contained in this map.
- See Also:
Map.keySet()
-
values
public ObjectCollection<V> values()
Description copied from interface:Byte2ObjectMap
Note that this specification strengthens the one given in
Map.values()
.- Specified by:
values
in interfaceByte2ObjectMap<V>
- Specified by:
values
in interfacejava.util.Map<java.lang.Byte,V>
- Returns:
- a set view of the values contained in this map.
