createMap

protected MutableMap<K, MutableList<V>> createMap()

Specified by:

createMap in class AbstractMutableMultimap<K, V, MutableList<V>>

createMapWithKeyCount

protected MutableMap<K, MutableList<V>> createMapWithKeyCount(int keyCount)

Specified by:

createMapWithKeyCount in class AbstractMutableMultimap<K, V, MutableList<V>>

createCollection

protected MutableList<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:

createCollection in class AbstractMultimap<K, V, MutableList<V>>

Returns:

an empty collection of values

newEmpty

public MultiReaderFastListMultimap<K,V> newEmpty()

Description copied from interface: Multimap

Creates a new instance of the same implementation type, using the default capacity and growth parameters.

Specified by:

newEmpty in interface ListMultimap<K,V>

Specified by:

flip

public MutableBagMultimap<V,K> flip()

Description copied from interface: Multimap

Given a Multimap from Domain -> Range return a multimap from Range -> Domain.

Specified by:

selectKeysValues

public FastListMultimap<K,V> selectKeysValues(Predicate2<? super K, ? super V> predicate)

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)
                 && (person.getAddress().getCity().equals("Metuchen"));
    }
