public boolean containsValue(java.lang.Object v)

    containsValue in interface java.util.Map<K,V>
  - putAll
```

  - object2ReferenceEntrySet
```
public ObjectSet<Object2ReferenceMap.Entry<K,V>> object2ReferenceEntrySet()
```
    Description copied from interface: Object2ReferenceMap
    
    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:
    
    object2ReferenceEntrySet in interface Object2ReferenceMap<K,V>
    
    Returns:
    
    a type-specific set view of the mappings contained in this map.
    
    See Also:
    
    Map.entrySet()
  - entrySet
```
public ObjectSet<java.util.Map.Entry<K,V>> entrySet()
```
    Returns a set view of the mappings contained in this map.
    Note that this specification strengthens the one given in Map.entrySet().
