  - containsValue

public boolean containsValue(short v)

  - putAll

public void putAll(java.util.Map<? extends K,? extends java.lang.Short> m)

  - object2ShortEntrySet
```
public ObjectSet<Object2ShortMap.Entry<K>> object2ShortEntrySet()
```
    Description copied from interface: Object2ShortMap
    
    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 Object2ShortMap.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:
    
    object2ShortEntrySet in interface Object2ShortMap<K>
    
    Returns:
    
    a type-specific set view of the mappings contained in this map.
    
    See Also:
    
    Object2ShortMap.entrySet()
  - keySet
```
public ObjectSet<K> keySet()
```
    Description copied from interface: Object2ShortMap
    
    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 Object2ShortMap<K>
    
    Specified by:
    
    keySet in interface java.util.Map<K,java.lang.Short>
    
    Returns:
    
    a set view of the keys contained in this map.

public ShortCollection values()
```
    Description copied from interface: Object2ShortMap
    
    Returns a set view of the values contained in this map.
    Note that this specification strengthens the one given in Map.values().

    values in interface Object2ShortMap<K>
    
    Specified by:
    
    values in interface java.util.Map<K,java.lang.Short>
