public static class Float2ReferenceMaps.EmptyMap<V>
- extends Float2ReferenceFunctions.EmptyFunction<V>
- implements Float2ReferenceMap<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<Float,V>
putAll
public void putAll(Map<? extends Float,? extends V> m)
- Specified by:
putAll
in interface Map<Float,V>
float2ReferenceEntrySet
public ObjectSet<Float2ReferenceMap.Entry<V>> float2ReferenceEntrySet()
- Description copied from interface:
Float2ReferenceMap
- 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 Float2ReferenceMap.entrySet()
so that it returns an ObjectSet
of objects of type Float2ReferenceMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
- Specified by:
float2ReferenceEntrySet
in interface Float2ReferenceMap<V>
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Float2ReferenceMap.entrySet()
keySet
public FloatSet keySet()
- Description copied from interface:
Float2ReferenceMap
- 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 Float2ReferenceMap<V>
- Specified by:
keySet
in interface Map<Float,V>
- Returns:
- a set view of the keys contained in this map.
- See Also:
Map.keySet()
values
public ReferenceCollection<V> values()
- Description copied from interface:
Float2ReferenceMap
- 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 Float2ReferenceMap<V>
- Specified by:
values
in interface Map<Float,V>
- Returns:
- a set view of the values contained in this map.
