Method Detail

containsValue
public boolean containsValue(int v)
Description copied from interface:Short2IntMap
Returnstrue
if this map maps one or more keys to the specified value.- Specified by:
containsValue
in interfaceShort2IntMap
- See Also:
Map.containsValue(Object)
-
containsValue
@Deprecated public boolean containsValue(java.lang.Object ov)
Deprecated.Please use the corresponding type-specific method instead.- Specified by:
containsValue
in interfacejava.util.Map<java.lang.Short,java.lang.Integer>
- Specified by:
containsValue
in interfaceShort2IntMap
-
putAll
public void putAll(java.util.Map<? extends java.lang.Short,? extends java.lang.Integer> m)
- Specified by:
putAll
in interfacejava.util.Map<java.lang.Short,java.lang.Integer>
-
short2IntEntrySet
public ObjectSet<Short2IntMap.Entry> short2IntEntrySet()
Description copied from interface:Short2IntMap
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:
short2IntEntrySet
in interfaceShort2IntMap
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
public ShortSet keySet()
Description copied from interface:Short2IntMap
Note that this specification strengthens the one given in
Map.keySet()
.- Specified by:
keySet
in interfacejava.util.Map<java.lang.Short,java.lang.Integer>
- Specified by:
keySet
in interfaceShort2IntMap
- Returns:
- a set view of the keys contained in this map.
- See Also:
Map.keySet()
-
values
public IntCollection values()
Description copied from interface:Short2IntMap
Note that this specification strengthens the one given in
Map.values()
.- Specified by:
values
in interfacejava.util.Map<java.lang.Short,java.lang.Integer>
- Specified by:
values
in interfaceShort2IntMap
- Returns:
- a set view of the values contained in this map.
- See Also:
Map.values()
