public static class Object2LongMaps.EmptyMap<K>
- extends Object2LongFunctions.EmptyFunction<K>
- implements Object2LongMap<K>, 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(long v)
- Specified by:
containsValue
in interface Object2LongMap<K>
- See Also:
Map.containsValue(Object)
putAll
public void putAll(Map<? extends K,? extends Long> m)
- Specified by:

in interface Map<K,Long>
object2LongEntrySet
public ObjectSet<Object2LongMap.Entry<K>> object2LongEntrySet()
- Description copied from interface:
Object2LongMap
- 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 Object2LongMap.entrySet()
so that it returns an ObjectSet
of objects of type Object2LongMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
- Specified by:
object2LongEntrySet
in interface Object2LongMap<K>
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Object2LongMap.entrySet()

- Description copied from interface:
Object2LongMap
- 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 Object2LongMap<K>
- Specified by:
keySet
in interface Map<K,Long>
- Returns:

values
public LongCollection values()
- Description copied from interface:
Object2LongMap
- 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 Object2LongMap<K>
- Specified by:
values
in interface Map<K,Long>
- Returns:
- a set view of the values contained in this map.
