Method Detail

containsValue
public boolean containsValue(double v)
Description copied from interface:Float2DoubleMap
Returnstrue
if this map maps one or more keys to the specified value.- Specified by:
containsValue
in interfaceFloat2DoubleMap
- 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 interfaceFloat2DoubleMap
- Specified by:
containsValue
in interfaceMap<Float,Double>
-
float2DoubleEntrySet
public ObjectSet<Float2DoubleMap.Entry> float2DoubleEntrySet()
Description copied from interface:Float2DoubleMap
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:
float2DoubleEntrySet
in interfaceFloat2DoubleMap
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
public FloatSet keySet()
Description copied from interface:Float2DoubleMap
Note that this specification strengthens the one given in
Map.keySet()
.- Specified by:
keySet
in interfaceFloat2DoubleMap
- Specified by:
keySet
in interfaceMap<Float,Double>
- Returns:
- a set view of the keys contained in this map.
- See Also:
Map.keySet()
-
values
public DoubleCollection values()
Description copied from interface:Float2DoubleMap
Note that this specification strengthens the one given in
Map.values()
.- Specified by:
values
in interfaceFloat2DoubleMap
- Specified by:
values
in interfaceMap<Float,Double>
- Returns:
- a set view of the values contained in this map.
- See Also:
Map.values()
