public static class Long2ReferenceMaps.Singleton<V>
- extends Long2ReferenceFunctions.Singleton<V>
- implements Long2ReferenceMap<V>, Serializable, Cloneable
An immutable class representing a type-specific singleton 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<Long,V>
putAll
public void putAll(Map<? extends Long,? extends V> m)
- Specified by:
putAll
in interface Map<Long,V>
long2ReferenceEntrySet
public ObjectSet<Long2ReferenceMap.Entry<V>> long2ReferenceEntrySet()
- Description copied from interface:
Long2ReferenceMap
- 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 Long2ReferenceMap.entrySet()
so that it returns an ObjectSet
of objects of type Long2ReferenceMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
- Specified by:
long2ReferenceEntrySet
in interface Long2ReferenceMap<V>
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
