public static class Object2LongMaps.Singleton<K> extends Object2LongFunctions.Singleton<K> implements Object2LongMap<K>, Serializable, Cloneable

object2LongEntrySet
Description copied from interface:Object2LongMapReturns 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 anObjectSetof type-specific entries (the latter makes it possible to access keys and values with type-specific methods).- Specified by:
object2LongEntrySetin interfaceObject2LongMap<K>- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
entrySet
Deprecated.Please use the corresponding type-specific method instead.Returns a set view of the mappings contained in this map.Note that this specification strengthens the one given in
Map.entrySet().- Specified by:
entrySetin interfaceMap<K,Long>- Specified by:
entrySetin interfaceObject2LongMap<K>- Returns:
- a set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
Description copied from interface:Object2LongMapNote that this specification strengthens the one given in
Map.keySet().- Specified by:
keySetin interfaceMap<K,Long>- Specified by:
keySetin interfaceObject2LongMap<K>- Returns:
- a set view of the keys contained in this map.
- See Also:
Map.keySet()
-
values
Description copied from interface:Object2LongMapNote that this specification strengthens the one given in
Map.values().- Specified by:
