Returns:

asSynchronized

MutableSetMultimap<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>

Specified by:

asSynchronized in interface MutableSetIterableMultimap<K,V>

Returns:

a synchronized view of this multimap.
