          extended by com.google.common.collect.ForwardingSetMultimap<K,V>
              extended by com.google.common.collect.ForwardingSortedSetMultimap<K,V>
All Implemented Interfaces:
Multimap<K,V>, SetMultimap<K,V>, SortedSetMultimap<K,V>
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.

Constructor Summary
protected ForwardingSortedSetMultimap()
          Constructor for use by subclasses.
 
Method Summary
protected abstract  SortedSetMultimap<K,V> delegate()
          Returns the backing delegate instance that methods are forwarded to.
 SortedSet<V> get(K key)
          Returns a collection view of all values associated with a key.
 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 a null indicating that natural ordering is used.

Constructor Detail

ForwardingSortedSetMultimap

protected ForwardingSortedSetMultimap()
Constructor for use by subclasses.

Method Detail

delegate

protected abstract SortedSetMultimap<K,V> delegate()
Description copied from class: ForwardingObject
Returns the backing delegate instance that methods are forwarded to. Abstract subclasses generally override this method with an abstract method that has a more specific return type, such as ForwardingSet.delegate(). Concrete subclasses override this method to supply the instance being decorated.

Specified by:
delegate in class ForwardingSetMultimap<K,V>

get

public SortedSet<V> get(@Nullable
                        K key)
Description copied from interface: Multimap
Returns a collection view of all values associated with a key. If no mappings in the multimap have the provided key, an empty collection is returned.

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:
the collection of 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.

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.

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 a null indicating that natural ordering is used.

Specified by:
valueComparator in interface SortedSetMultimap<K,V>
