@GwtCompatible
public abstract class ForwardingSortedSetMultimap<K,V>
extends ForwardingSetMultimap<K,V>
implements SortedSetMultimap<K,V>

A sorted set multimap which forwards all its method calls to another sorted set multimap. Subclasses should override one or more methods to modify the behavior of the backing multimap as desired per the decorator pattern.

Since:

3.0

Method Summary

Modifier and Type	Method and Description
SortedSet<V>	get(K key) Returns a collection view containing the values associated with key in this multimap, if any.
SortedSet<V>	removeAll(Object key) Removes all values associated with a given key.
SortedSet<V>	replaceValues(K key, Iterable<? extends V> values) Stores a collection of values with the same key, replacing any existing values for that key.
Comparator<? super V>	valueComparator() Returns the comparator that orders the multimap values, with null indicating that natural ordering is used.

Method Detail

get

public SortedSet<V> get(@Nullable
                        K key)

Description copied from interface: Multimap

Returns a collection view containing the values associated with key in this multimap, if any. Note that even when (containsKey(key) is false, get(key) still returns an empty collection, not null.

Changes to the returned collection will update the underlying multimap, and vice versa.

Specified by:

get in interface Multimap<K,V>

Specified by:

get in interface SetMultimap<K,V>

Specified by:

get in interface SortedSetMultimap<K,V>

Overrides:

get in class ForwardingSetMultimap<K,V>

Parameters:

key - key to search for in multimap

Returns:

a view collection containing the zero or more values that the key maps to

removeAll

public SortedSet<V> removeAll(@Nullable
                              Object key)

Description copied from interface: Multimap

Removes all values associated with a given key.

Once this method returns, key will not be mapped to any values, so it will not appear in Multimap.keySet(), Multimap.asMap(), or any other views.

Specified by:

removeAll in interface Multimap<K,V>

Specified by:

removeAll in interface SetMultimap<K,V>

Specified by:

removeAll in interface SortedSetMultimap<K,V>

Overrides:

removeAll in class ForwardingSetMultimap<K,V>

Parameters:

key - key of entries to remove from the multimap

Returns:

the collection of removed values, or an empty collection if no values were associated with the provided key. The collection may be modifiable, but updating it will have no effect on the multimap.

replaceValues

public SortedSet<V> replaceValues(K key,
                                  Iterable<? extends V> values)

Description copied from interface: Multimap

Stores a collection of values with the same key, replacing any existing values for that key.

If values is empty, this is equivalent to removeAll(key).

Specified by:

replaceValues in interface Multimap<K,V>

Specified by:

replaceValues in interface SetMultimap<K,V>

Specified by:

replaceValues in interface SortedSetMultimap<K,V>

Overrides:

replaceValues in class ForwardingSetMultimap<K,V>

Parameters:

key - key to store in the multimap

values - values to store in the multimap

Returns:

the collection of replaced values, or an empty collection if no values were previously associated with the key. The collection may be modifiable, but updating it will have no effect on the multimap.

valueComparator

public Comparator<? super V> valueComparator()

Description copied from interface: SortedSetMultimap

Returns the comparator that orders the multimap values, with null indicating that natural ordering is used.

Specified by:

valueComparator in interface SortedSetMultimap<K,V>
