public static class Double2ObjectMaps.Singleton<V> extends Double2ObjectFunctions.Singleton<V> implements Double2ObjectMap<V>, java.io.Serializable, java.lang.Cloneable
An immutable class representing a type-specific singleton map.
This class may be useful to implement your own in case you subclass a type-specific map.

containsValue
public boolean containsValue(java.lang.Object v)- Specified by:

-
putAll
- Specified by:
putAll
in interfacejava.util.Map<java.lang.Double,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.Please use the corresponding type-specific method instead.Returns a set view of the mappings contained in this map.- Specified by:
entrySet
in interfaceDouble2ObjectMap<V>
- Specified by:
entrySet
in interfacejava.util.Map<java.lang.Double,V>
- Returns:
- a set view of the mappings contained in this map.
- See Also:

keySet
Description copied from interface:Double2ObjectMap
- Specified by:
keySet
in interfaceDouble2ObjectMap<V>
- Specified by:

in interfacejava.util.Map<java.lang.Double,V>
- Returns:
- a set view of the keys contained in this map.
