UnifiedSetWithHashingStrategyMultimap

@Deprecated
public UnifiedSetWithHashingStrategyMultimap()

Deprecated.

Empty default constructor used for serialization. Instantiating an UnifiedSetWithHashingStrategyMultimap with this constructor will have a null hashingStrategy and throw NullPointerException when used.

createCollection

protected UnifiedSetWithHashingStrategy<V> createCollection()

Description copied from class: AbstractMultimap

Creates the collection of values for a single key.

Collections with weak, soft, or phantom references are not supported. Each call to createCollection should create a new instance.

The returned collection class determines whether duplicate key-value pairs are allowed.

Specified by:

Returns:

an empty collection of values

newEmpty

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