Method Detail
-
unfiltered
public SetMultimap<K,V> unfiltered()
- Specified by:
unfiltered
in interfaceFilteredMultimap<K,V>
- Specified by:
unfiltered
in interfaceFilteredSetMultimap<K,V>
- Overrides:
unfiltered
in classFilteredKeyMultimap<K,V>
-
get
public java.util.Set<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 java.util.Set<V> removeAll(java.lang.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,V>
- Specified by:
removeAll
in interfaceSetMultimap<K,V>
- Overrides:
removeAll
in classFilteredKeyMultimap<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
public java.util.Set<V> replaceValues(K key, java.lang.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,V>
- Specified by:
replaceValues
in interfaceSetMultimap<K,V>
- Overrides:
replaceValues
in classAbstractMultimap<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.
-
entries
public java.util.Set<java.util.Map.Entry<K,V>> entries()
Description copied from interface:Multimap
Returns a view collection of all key-value pairs contained in this multimap, asMap.Entry
instances.Changes to the returned collection or the entries it contains will update the underlying multimap, and vice versa. However, adding to the returned collection is not possible.

createEntries
java.util.Set<java.util.Map.Entry<K,V>> createEntries()
- Overrides:

in classFilteredKeyMultimap<K,V>
