public static class Long2FloatMaps.EmptyMap
- extends Long2FloatFunctions.EmptyFunction
- implements Long2FloatMap, 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(float v)
- Specified by:
containsValue
in interface Long2FloatMap
- See Also:
Map.containsValue(Object)
putAll
public void putAll(Map<? extends Long,? extends Float> m)
- Specified by:
putAll
in interface Map<Long,Float>
long2FloatEntrySet
public ObjectSet<Long2FloatMap.Entry> long2FloatEntrySet()
- Description copied from interface:
Long2FloatMap
- 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 Long2FloatMap.entrySet()
so that it returns an ObjectSet
of objects of type Long2FloatMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
- Specified by:
long2FloatEntrySet
in interface Long2FloatMap
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Long2FloatMap.entrySet()
keySet
public LongSet keySet()
- Description copied from interface:
Long2FloatMap
- 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 Long2FloatMap
- Specified by:
keySet
in interface Map<Long,Float>
- Returns:
- a set view of the keys contained in this map.
- See Also:

values
public FloatCollection values()
- Description copied from interface:
Long2FloatMap
- 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 Long2FloatMap
- Specified by:
values
in interface Map<Long,Float>
- Returns:
- a set view of the values contained in this map.
