public MutableBiMap<K,V> asSynchronized()
MutableMapIterable
Collections.synchronizedMap(this)
only with the more feature rich return type of
MutableMapIterable
.
The preferred way of iterating over a synchronized map is to use the forEachKey(), forEachValue() and forEachKeyValue() methods which are properly synchronized internally.
MutableMap synchedMap = map.asSynchronized(); synchedMap.forEachKey(key -> ... ); synchedMap.forEachValue(value -> ... ); synchedMap.forEachKeyValue((key, value) -> ... );
If you want to iterate imperatively over the keySet(), values(), or entrySet(), you will need to protect the iteration by wrapping the code in a synchronized block on the map.

Since the keys in the input are unique, the values in the output are unique, so the return type should be a SetMultimap. However since SetMultimap and SortedSetMultimap don't inherit from one another, SetMultimap here does not allow SortedMapIterable to have a SortedSetMultimap return. Thus we compromise and call this Multimap, even though all implementations will be a SetMultimap or SortedSetMultimap.
