Class ForwardingSetMultimap<K,V>

    • Constructor Detail

      • ForwardingSetMultimap

        public ForwardingSetMultimap()

    • Method Detail

      • delegate

        protected abstract 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.

      • 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.

      • 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.

      • removeAll

        public Set<V> removeAll(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  ForwardingMultimap<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  ForwardingMultimap<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.
