public boolean containsValue(short v)

  - long2ShortEntrySet
```
public ObjectSet<Long2ShortMap.Entry> long2ShortEntrySet()
```
    Description copied from interface: Long2ShortMap
    
    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 Long2ShortMap.entrySet() so that it returns an ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).
    
    Specified by:
    
    long2ShortEntrySet in interface Long2ShortMap
    
    Returns:
    
    a type-specific set view of the mappings contained in this map.

    Long2ShortMap.entrySet()
  - keySet
```
public LongSet keySet()
```
    Description copied from interface: Long2ShortMap
    
    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 java.util.Map<java.lang.Long,java.lang.Short>
