  - containsValue
```
public boolean containsValue(java.lang.Object v)
```
    Specified by:
    
    containsValue in interface java.util.Map<java.lang.Short,V>
  - putAll
```
public void putAll(java.util.Map<? extends java.lang.Short,? extends V> m)
```
    Specified by:

  - short2ReferenceEntrySet
```
public ObjectSet<Short2ReferenceMap.Entry<V>> short2ReferenceEntrySet()
```
    Description copied from interface: Short2ReferenceMap
    
    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 an ObjectSet of type-specific entries (the latter makes it possible to access keys and values with type-specific methods).
    
    Specified by:
    
    short2ReferenceEntrySet in interface Short2ReferenceMap<V>
    
    Returns:
    
    a type-specific set view of the mappings contained in this map.

```
public ShortSet keySet()

    Description copied from interface: Short2ReferenceMap
    
    Note that this specification strengthens the one given in Map.keySet().
    
    Specified by:
    
    keySet in interface java.util.Map<java.lang.Short,V>
    
    Specified by:
    
    keySet in interface Short2ReferenceMap<V>
    
    Returns:
    
    a set view of the keys contained in this map.

    values in interface java.util.Map<java.lang.Short,V>
    
    Specified by:
    
    values in interface Short2ReferenceMap<V>
