Method Detail

containsValue
public boolean containsValue(Object v)
- Specified by:
containsValue
in interfaceMap<Double,V>
-
double2ObjectEntrySet
public ObjectSet<Double2ObjectMap.Entry<V>> double2ObjectEntrySet()
Description copied from interface:Double2ObjectMap
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:
double2ObjectEntrySet
in interfaceDouble2ObjectMap<V>
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
entrySet
@Deprecated public ObjectSet<Map.Entry<Double,V>> 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 interfaceDouble2ObjectMap<V>
- Specified by:
entrySet
in interfaceMap<Double,V>
- Returns:
- a set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
public DoubleSet keySet()
Description copied from interface:Double2ObjectMap
Note that this specification strengthens the one given in
Map.keySet()
.- Specified by:
keySet
in interfaceDouble2ObjectMap<V>
- Specified by:
keySet
in interfaceMap<Double,V>
- Returns:
- a set view of the keys contained in this map.

values
public ObjectCollection<V> values()
Description copied from interface:Double2ObjectMap
Note that this specification strengthens the one given in
Map.values()
.- Specified by:
values
in interfaceDouble2ObjectMap<V>
- Specified by:
