collectValues

public <V2> HashBagMultimap<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.

e.g.
 return multimap.collectValues(new Function<Person, String>()
 {
     public String valueOf(Person person)
     {
         return person.getLastName();
     }

Description copied from interface: Multimap

Returns all elements of the source multimap that satisfies the predicate. This method is also commonly called filter.

e.g.
 return multimap.selectKeysValues(new Predicate2<Integer, Person>()
 {
     public boolean accept(Integer age, Person person)
     {
         return (age >= 18)
