Method Detail
-
containsValue
public boolean containsValue(short v)
Description copied from interface:Object2ShortMap
Returnstrue
if this map maps one or more keys to the specified value.- Specified by:
containsValue
in interfaceObject2ShortMap<K>
- See Also:
Map.containsValue(Object)
-
containsValue
@Deprecated public boolean containsValue(Object ov)
Deprecated.Please use the corresponding type-specific method instead.- Specified by:
containsValue
in interfaceMap<K,Short>
- Specified by:
containsValue
in interfaceObject2ShortMap<K>
-
object2ShortEntrySet
public ObjectSet<Object2ShortMap.Entry<K>> object2ShortEntrySet()
Description copied from interface:Object2ShortMap
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
Map.entrySet()
so that it returns anObjectSet
of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).- Specified by:
object2ShortEntrySet
in interfaceObject2ShortMap<K>
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
entrySet
@Deprecated public ObjectSet<Map.Entry<K,Short>> 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:
entrySet
in interfaceMap<K,Short>
- Specified by:
entrySet
in interfaceObject2ShortMap<K>
- Returns:
- a set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
public ObjectSet<K> keySet()
Description copied from interface:Object2ShortMap
Note that this specification strengthens the one given in
Map.keySet()
.- Specified by:
keySet
in interfaceMap<K,Short>
- Specified by:
keySet
in interfaceObject2ShortMap<K>
- Returns:
- a set view of the keys contained in this map.
- See Also:
Map.keySet()
-
values
public ShortCollection values()
Description copied from interface:Object2ShortMap
Note that this specification strengthens the one given in
Map.values()
.- Specified by:
values
in interfaceMap<K,Short>
- Specified by:
values
in interfaceObject2ShortMap<K>
- Returns:
- a set view of the values contained in this map.
