Method Detail

get

RSetRx<V> get(K key)

Returns a view Set 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.

Parameters:

key - - map key

Returns:

set of values

getAll

io.reactivex.Single<Set<V>> getAll(K key)

Returns all elements at once. Result Set is NOT backed by map, so changes are not reflected in map.

Parameters:

key - - map key

Returns:

set of values

removeAll

io.reactivex.Single<Set<V>> removeAll(Object key)

Removes all values associated with the key key.

Once this method returns, key will not be mapped to any values

Use RMultimapReactive.fastRemove(K...) if values are not needed.

Parameters:

key - - map key

Returns:

the values that were removed (possibly empty). The returned set may be modifiable, but updating it will have no effect on the multimap.

replaceValues

io.reactivex.Single<Set<V>> replaceValues(K key,
                                          Iterable<? extends V> values)

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(Object).

Parameters:

key - - map key

values - - map values

Returns:

set of replaced values, or an empty collection if no values were previously associated with the key. Set may be modifiable, but updating it will have no effect on the multimap.
