@GwtCompatible public abstract class ForwardingSortedSetMultimap<K extends @Nullable Object,V extends @Nullable Object> 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.default
method warning: This class does not forward calls todefault
methods. Instead, it inherits their default implementations. When those implementations invoke methods, they invoke methods on theForwardingSortedSetMultimap

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 asForwardingSet.delegate()
. Concrete subclasses override this method to supply the instance being decorated.
-
get
public SortedSet<V> get(K key)
Description copied from interface:Multimap
Returns a view collection of the values associated withkey
in this multimap, if any. Note that whencontainsKey(key)
is false, this returns an empty collection, notnull
.Changes to the returned collection will update the underlying multimap, and vice versa.

removeAll
public SortedSet<V> removeAll(@Nullable Object key)
Description copied from interface:Multimap
Removes all values associated with the keykey
.Once this method returns,
key
will not be mapped to any values, so it will not appear inMultimap.keySet()
,Multimap.asMap()
, or any other views.- Specified by:
removeAll
in interfaceMultimap<K extends @Nullable Object,V extends @Nullable Object>
- Specified by:
removeAll
in interfaceSetMultimap<K extends @Nullable Object,V extends @Nullable Object>
- Specified by:
removeAll
in interfaceSortedSetMultimap<K extends @Nullable Object,V extends @Nullable Object>
- Overrides:
removeAll
in classForwardingSetMultimap<K extends @Nullable Object,V extends @Nullable Object>
- Returns:
- the values that were removed (possibly empty). The returned 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 toremoveAll(key)
.- Specified by:
replaceValues
in interfaceMultimap<K extends @Nullable Object,V extends @Nullable Object>
- Specified by:
replaceValues

- Specified by:

in interfaceSortedSetMultimap<K extends @Nullable Object,V extends @Nullable Object>
- Overrides:
replaceValues
in classForwardingSetMultimap<K extends @Nullable Object,V extends @Nullable Object>
- 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 @Nullable Comparator<? super V> valueComparator()
Description copied from interface:SortedSetMultimap
Returns the comparator that orders the multimap values, withnull
indicating that natural ordering is used.- Specified by:
