Method Detail

unfiltered

public ListMultimap<K,V> unfiltered()

Specified by:

unfiltered in interface FilteredMultimap<K,V>

Overrides:

unfiltered in class FilteredKeyMultimap<K,V>

get

public java.util.List<V> get(K key)

Description copied from interface: Multimap

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

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

Specified by:

get in interface ListMultimap<K,V>

Specified by:

get in interface Multimap<K,V>

Overrides:

get in class FilteredKeyMultimap<K,V>

removeAll

public java.util.List<V> removeAll(java.lang.Object key)

Description copied from interface: Multimap

Removes all values associated with the key 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 ListMultimap<K,V>

Specified by:

removeAll in interface Multimap<K,V>

Overrides:

removeAll in class FilteredKeyMultimap<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.List<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 to removeAll(key).

Specified by:

replaceValues in interface ListMultimap<K,V>

Specified by:

replaceValues in interface Multimap<K,V>

Overrides:

replaceValues in class AbstractMultimap<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.
