Class AbstractSortedSetMultimap<K,V>
- All Implemented Interfaces:
Multimap<K,,V> SetMultimap<K,,V> SortedSetMultimap<K,,V> Serializable
- Direct Known Subclasses:
AbstractSortedKeySortedSetMultimap,Multimaps.CustomSortedSetMultimap
SortedSetMultimap interface. It's a wrapper around AbstractMapBasedMultimap that converts the returned collections into sorted sets. The createCollection() method must return a SortedSet.-

AbstractSortedSetMultimap
Creates a new multimap that uses the provided map.- Parameters:
map- place to store the mapping from each key to its corresponding values
-
-
Method Details
-
createCollection
Description copied from class:AbstractMapBasedMultimapCreates the collection of values for a single key.Collections with weak, soft, or phantom references are not supported. Each call to
createCollectionshould create a new instance.The returned collection class determines whether duplicate key-value pairs are allowed.
- Specified by:
createCollectionin classAbstractSetMultimap<K,V> - Returns:
- an empty collection of values
-
createUnmodifiableEmptyCollection
Description copied from class:AbstractMapBasedMultimapCreates an unmodifiable, empty collection of values.This is used in
AbstractMapBasedMultimap.removeAll(java.lang.Object)on an empty key.- Overrides:
createUnmodifiableEmptyCollectionin classAbstractSetMultimap<K,V>
-
unmodifiableCollectionSubclass
- Overrides:
unmodifiableCollectionSubclassin classAbstractSetMultimap<K,V>
-
wrapCollection
Description copied from class:AbstractMapBasedMultimapGenerates 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:
wrapCollectionin classAbstractSetMultimap<K,V>
-
get
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.
Because a
SortedSetMultimaphas unique sorted values for a given key, this method returns aSortedSet, instead of theCollectionspecified in theMultimapinterface. -
removeAll
Removes all values associated with a given key. The returned collection is immutable.Because a
SortedSetMultimaphas unique sorted values for a given key, this method returns aSortedSet, instead of theCollectionspecified in theMultimapinterface.- Specified by:
removeAllin interfaceMultimap<K,V> - Specified by:
removeAllin interfaceSetMultimap<K,V> - Specified by:
removeAllin interfaceSortedSetMultimap<K,V> - Overrides:
removeAllin classAbstractSetMultimap<K,V> - 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
Stores a collection of values with the same key, replacing any existing values for that key. The returned collection is immutable.Because a
SortedSetMultimaphas unique sorted values for a given key, this method returns aSortedSet, instead of theCollectionspecified in theMultimapinterface.Any duplicates in
valueswill be stored in the multimap once.- Specified by:
replaceValuesin interfaceMultimap<K,V> - Specified by:
replaceValuesin interfaceSetMultimap<K,V> - Specified by:
replaceValuesin interfaceSortedSetMultimap<K,V> - Overrides:
replaceValuesin classAbstractSetMultimap<K,V> - 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.
-
asMap
Returns a map view that associates each key with the corresponding values in the multimap. Changes to the returned map, such as element removal, will update the underlying multimap. The map does not supportsetValueon its entries,put, orputAll.When passed a key that is present in the map,
asMap().get(Object)has the same behavior asget(K), returning a live collection. When passed a key that is not present, however,asMap().get(Object)returnsnullinstead of an empty collection.Though the method signature doesn't say so explicitly, the returned map has
SortedSetvalues. -
values
Returns a view collection containing the value from each key-value pair contained in this multimap, without collapsing duplicates (sovalues().size() == size()).Changes to the returned collection will update the underlying multimap, and vice versa. However, adding to the returned collection is not possible.
The iterator generated by the returned collection traverses the values for one key, followed by the values of a second key, and so on.
Consequently, the values do not follow their natural ordering or the ordering of the value comparator.
