Interface SortedSetMultimap<K,​V>

    • Method Detail

      • get

        SortedSet<V> get​(@Nullable
                         K key)
        Returns a collection view of all values associated with a key. If no mappings in the multimap have the provided key, an empty collection is returned.

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

        Because a SortedSetMultimap has unique sorted values for a given key, this method returns a SortedSet, instead of the Collection specified in the Multimap interface.

        Specified by:
        get in interface Multimap<K,​V>
        Specified by:
        get in interface SetMultimap<K,​V>
        Parameters:
        key - key to search for in multimap
        Returns:
        a view collection containing the zero or more values that the key maps to
      • removeAll

        SortedSet<V> removeAll​(@Nullable
                               Object key)
        Removes all values associated with a given key.

        Because a SortedSetMultimap has unique sorted values for a given key, this method returns a SortedSet, instead of the Collection specified in the Multimap interface.

        Specified by:
        removeAll in interface Multimap<K,​V>
        Specified by:
        removeAll in interface SetMultimap<K,​V>
        Parameters:
        key - key of entries to remove from the multimap
        Returns:
        the collection of removed values, or an empty collection if no values were associated with the provided key. The collection may be modifiable, but updating it will have no effect on the multimap.
      • replaceValues

        SortedSet<V> replaceValues​(K key,
                                   Iterable<? extends V> values)
        Stores a collection of values with the same key, replacing any existing values for that key.

        Because a SortedSetMultimap has unique sorted values for a given key, this method returns a SortedSet, instead of the Collection specified in the Multimap interface.

        Any duplicates in values will be stored in the multimap once.

        Specified by:
        replaceValues in interface Multimap<K,​V>
        Specified by:
        replaceValues in interface SetMultimap<K,​V>
        Parameters:
        key - key to store in the multimap
        values - values to store in the multimap
        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.
      • asMap

        Map<K,​Collection<V>> asMap()
        Returns a map view that associates each key with the corresponding values in the multimap. Changes to the returned map, such as element removal, will update the underlying multimap. The map does not support setValue() on its entries, put, or putAll.

        When passed a key that is present in the map, asMap().get(Object) has the same behavior as get(K), returning a live collection. When passed a key that is not present, however, asMap().get(Object) returns null instead of an empty collection.

        Note: The returned map's values are guaranteed to be of type SortedSet. To obtain this map with the more specific generic type Map<K, SortedSet<V>>, call Multimaps.asMap(SortedSetMultimap) instead.

        Specified by:
        asMap in interface Multimap<K,​V>
        Specified by:
        asMap in interface SetMultimap<K,​V>
        Returns:
        a map view from a key to its collection of values
      • valueComparator

        Comparator<? super V> valueComparator()
        Returns the comparator that orders the multimap values, with null indicating that natural ordering is used.
