public static class Int2IntMaps.Singleton
- extends Int2IntFunctions.Singleton
- implements Int2IntMap, Serializable, 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.

public boolean containsValue(Object ov)
- Specified by:

in interface Map<Integer,Integer>

public void putAll(Map<? extends Integer,? extends Integer> m)
- Specified by:

in interface Map<Integer,Integer>
int2IntEntrySet
public ObjectSet<Int2IntMap.Entry> int2IntEntrySet()
- Description copied from interface:
Int2IntMap
- 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 Int2IntMap.entrySet()
so that it returns an ObjectSet
of objects of type Int2IntMap.Entry
(the latter makes it possible to
access keys and values with type-specific methods).
- Specified by:
int2IntEntrySet
in interface Int2IntMap
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Int2IntMap.entrySet()

in interface Int2IntMap
- Specified by:
keySet
in interface Map<Integer,Integer>
- Returns:

values
public IntCollection values()
- Description copied from interface:
Int2IntMap
