  • Method Details

    • delegate

      public SetMultimap<K,V> delegate()
      Description copied from class: ForwardingObject
      Returns the backing delegate instance that methods are forwarded to. Abstract subclasses generally override this method with an abstract method that has a more specific return type, such as ForwardingSet.delegate(). Concrete subclasses override this method to supply the instance being decorated.
      Overrides:
      delegate in class Multimaps.UnmodifiableMultimap<K,V>
    • get

      public Set<V> get(K key)
      Description copied from interface: Multimap
      Returns a view collection of the values associated with key in this multimap, if any. Note that when containsKey(key) is false, this returns an empty collection, not null.

      Changes to the returned collection will update the underlying multimap, and vice versa.

      Specified by:
      get in interface Multimap<K,V>
      Specified by:
      get in interface SetMultimap<K,V>
      Overrides:
      get in class Multimaps.UnmodifiableMultimap<K,V>
    • entries

      public Set<Map.Entry<K,V>> entries()
      Description copied from interface: Multimap
      Returns a view collection of all key-value pairs contained in this multimap, as Map.Entry instances.

      Changes to the returned collection or the entries it contains will update the underlying multimap, and vice versa. However, adding to the returned collection is not possible.

      Specified by:
      entries in interface Multimap<K,V>
      Specified by:
      entries in interface SetMultimap<K,V>
      Overrides:
      entries in class Multimaps.UnmodifiableMultimap<K,V>
    • removeAll

      public Set<V> removeAll(@CheckForNull Object key)
      Description copied from interface: Multimap
      Removes all values associated with the key key.

      Once this method returns, key will not be mapped to any values, so it will not appear in Multimap.keySet(), Multimap.asMap(), or any other views.

      Specified by:
      removeAll in interface Multimap<K,V>
      Specified by:
      removeAll in interface SetMultimap<K,V>
      Overrides:
      removeAll in class Multimaps.UnmodifiableMultimap<K,V>
      Returns:
      the values that were removed (possibly empty). The returned collection may be modifiable, but updating it will have no effect on the multimap.
    • replaceValues

      public Set<V> replaceValues(K key, Iterable<? extends V> values)
      Description copied from interface: Multimap
      Stores a collection of values with the same key, replacing any existing values for that key.

      If values is empty, this is equivalent to removeAll(key).

      Specified by:
      replaceValues in interface Multimap<K,V>
      Specified by:
      replaceValues in interface SetMultimap<K,V>
      Overrides:
      replaceValues in class Multimaps.UnmodifiableMultimap<K,V>
      Returns:
      the collection of replaced values, or an empty collection if no values were previously associated with the key. The collection may be modifiable, but updating it will have no effect on the multimap.
