public static class Int2IntMaps.EmptyMap
- extends Int2IntFunctions.EmptyFunction
- implements Int2IntMap, Serializable, Cloneable
An immutable class representing an empty type-specific map.
This class may be useful to implement your own in case you subclass
a type-specific map.

containsValue
public boolean containsValue(int v)
- Specified by:
containsValue
in interface Int2IntMap
- See Also:
Map.containsValue(Object)
putAll
public void putAll(Map<? extends Integer,? extends Integer> m)
- Specified by:
putAll
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()

public IntSet keySet()
- Description copied from interface:
Int2IntMap
- Returns a set view of the keys contained in this map.
Note that this specification strengthens the one given in Map.keySet()
.
- Specified by:
keySet
in interface Int2IntMap
- Specified by:
keySet
in interface Map<Integer,Integer>
- Returns:
- a set view of the keys contained in this map.
- See Also:

values
public IntCollection values()
- Description copied from interface:
Int2IntMap
- Returns a set view of the values contained in this map.
Note that this specification strengthens the one given in Map.values()
.
- Specified by:
values
in interface Int2IntMap
- Specified by:
values
in interface Map<Integer,Integer>
