    • collectValues

      <V2> MutableMultimap<K,V2> collectValues(Function<? super V,? extends V2> function)
      Description copied from interface: Multimap
      Returns a new multimap with the results of applying the specified function on each value of the source multimap. This method is also commonly called transform or map.

    • asSynchronized

      MutableSetIterableMultimap<K,V> asSynchronized()
      Description copied from interface: MutableMultimap
      Returns a synchronized wrapper backed by this multimap. The preferred way of iterating over a synchronized multimap is to use the forEachKey(), forEachValue(), forEachKeyValue() and forEachKeyMultiValues methods which are properly synchronized internally. 
        MutableMultimap synchedMultimap = multimap.asSynchronized();

  synchedMultimap.forEachKey(key -> ... );
  synchedMultimap.forEachValue(value -> ... );
  synchedMultimap.forEachKeyValue((key, value) -> ... );
  synchedMultimap.forEachKeyMultiValues((key, values) -> ... );

      If you want to iterate imperatively over the keySet(), keysView(), valuesView(), or other views, you will need to protect the iteration by wrapping the code in a synchronized block on the multimap.

      Specified by:
      asSynchronized in interface MutableMultimap<K,V>
      Returns:
      a synchronized view of this multimap.
