SetMultimap<K, V> class
A multimap that stores values in a Set, and that keeps the unique values
of a given key. A factory can be provided to create custom value
collections.
Constructors
-
SetMultimap({Map<
K, Set< ? map, Factory<V> >Set< ? factory})V> > -
Creates an empty SetMultimap with the keys held in
mapand the values in a collection built withfactory. -
SetMultimap.fromEntries(Iterable<
MapEntry< entries, {Map<K, V> >K, Set< ? map, Factory<V> >Set< ? factory})V> > -
Creates a SetMultimap containing the entries of
entries.factory -
SetMultimap.fromIterable(Iterable<
Object?> iterable, {K key(Object? element)?, V value(Object? element)?, Map<K, Set< ? map, Factory<V> >Set< ? factory})V> > -
Creates a SetMultimap with the keys and values computed from
iterable.factory -
SetMultimap.fromIterables(Iterable<
K> keys, Iterable<V> values, {Map<K, Set< ? map, Factory<V> >Set< ? factory})V> > -
factory
-
SetMultimap.identity({Factory<
Set< ? factory})V> > -
Creates a SetMultimap with identity keys.
factory
-
SetMultimap.of(Multimap<
K, V, Iterable< other, {Map<V> >K, Set< ? map, Factory<V> >Set< ? factory})V> > -
Creates a SetMultimap with the same keys and values as
other.factory
