Method Detail

createKeySet

java.util.Set<K> createKeySet()

Overrides:

createKeySet in class AbstractMapBasedMultimap<K,V>

createAsMap

java.util.Map<K,java.util.Collection<V>> createAsMap()

Overrides:

createAsMap in class AbstractMapBasedMultimap<K,V>

createCollection

protected java.util.Collection<V> createCollection()

Description copied from class: AbstractMapBasedMultimap

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 AbstractMapBasedMultimap<K,V>

Returns:

an empty collection of values

unmodifiableCollectionSubclass

<E> java.util.Collection<E> unmodifiableCollectionSubclass(java.util.Collection<E> collection)

Overrides:

unmodifiableCollectionSubclass in class AbstractMapBasedMultimap<K,V>

wrapCollection

java.util.Collection<V> wrapCollection(K key,
                                       java.util.Collection<V> collection)

Description copied from class: AbstractMapBasedMultimap

Generates a decorated collection that remains consistent with the values in the multimap for the provided key. Changes to the multimap may alter the returned collection, and vice versa.

Overrides:

wrapCollection in class AbstractMapBasedMultimap<K,V>

writeObject

private void writeObject(java.io.ObjectOutputStream stream)
                  throws java.io.IOException

Throws:

readObject

private void readObject(java.io.ObjectInputStream stream)
                 throws java.io.IOException,
                        java.lang.ClassNotFoundException

Throws:

java.io.IOException
