collectKeysValues
public <K2, V2> HashBagMultimap<K2,V2> collectKeysValues(Function2<? super K,? super V,Pair<K2,V2>> function)Description copied from interface:Multimap
Returns a new multimap with the results of applying the specified function on each key and value of the source multimap. This method is also commonly called transform or map.e.g. return multimap.collectKeysValues(new Function2<Integer, Person, Pair<String, String>>() { public Pair<String, String> valueOf(Integer age, Person person) { return Tuples.pair(age.toString(), person.getLastName()); } });

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.
