Method Detail

containsValue
public boolean containsValue(long v)
Description copied from interface:Int2LongMap
Returnstrue
if this map maps one or more keys to the specified value.- Specified by:
containsValue
in interfaceInt2LongMap
- 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 interfaceInt2LongMap
- Specified by:
containsValue
in interfaceMap<Integer,Long>
-
int2LongEntrySet
public ObjectSet<Int2LongMap.Entry> int2LongEntrySet()
Description copied from interface:Int2LongMap
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:
int2LongEntrySet
in interfaceInt2LongMap
- Returns:
- a type-specific set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
entrySet
@Deprecated public ObjectSet<Map.Entry<Integer,Long>> entrySet()
Deprecated.Please use the corresponding type-specific method instead.Returns a set view of the mappings contained in this map.Note that this specification strengthens the one given in
Map.entrySet()
.- Specified by:
entrySet
in interfaceInt2LongMap
- Specified by:
entrySet
in interfaceMap<Integer,Long>
- Returns:
- a set view of the mappings contained in this map.
- See Also:
Map.entrySet()
-
keySet
public IntSet keySet()
Description copied from interface:Int2LongMap
Note that this specification strengthens the one given in
Map.keySet()
.- Specified by:
keySet
in interfaceInt2LongMap
- Specified by:
keySet
in interfaceMap<Integer,Long>
- Returns:
- a set view of the keys contained in this map.
- See Also:
Map.keySet()
-
values
public LongCollection values()
Description copied from interface:Int2LongMap
Note that this specification strengthens the one given in
Map.values()
.- Specified by:
values
in interfaceInt2LongMap
- Specified by:
values
in interfaceMap<Integer,Long>
- Returns:
- a set view of the values contained in this map.
- See Also:
Map.values()
-
hashCode
public int hashCode()

equals
public boolean equals(Object o)
