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.
