java.lang.Object
  org.modeshape.common.collection.AbstractMultimap<K,V>
      org.modeshape.common.collection.ArrayListMultimap<K,V>

Type Parameters:

K - the key type

V - the value type

All Implemented Interfaces:

ListMultimap<K,V>, Multimap<K,V>

public class ArrayListMultimap<K,V>
extends AbstractMultimap<K,V>
implements ListMultimap<K,V>

A Multimap implementation that uses an ArrayList to store the values associated with a key. This implementation allows duplicates and the values are ordered.

Method Detail

create

public static <K,V> ArrayListMultimap<K,V> create()

Creates a new, empty LinkedHashMultimap (that allows no duplicates) with the default initial capacity.

Type Parameters:

K - the key type

V - the value type

Returns:

the new linked-hash multimap; never null

createCollection

protected Collection<V> createCollection()

Specified by:

createCollection in class AbstractMultimap<K,V>

AbstractMultimap.createCollection()

createUnmodifiableEmptyCollection

protected Collection<V> createUnmodifiableEmptyCollection()

Specified by:

createUnmodifiableEmptyCollection in class AbstractMultimap<K,V>

See Also:

AbstractMultimap.createUnmodifiableEmptyCollection()

get

public List<V> get(K key)

Get the collection of values that are associated with the supplied key.

Changes to the returned collection will update the values that this multimap associates with the key.

Specified by:

get in interface ListMultimap<K,V>

Specified by:

get in interface Multimap<K,V>

Overrides:

get in class AbstractMultimap<K,V>

Parameters:

key - the key

Returns:

the collection of values, or an empty collection if the supplied key was not associated with any values
