intersection method
override
Creates a new set which is the intersection between this set and other
.
That is, the returned set contains all the elements of this Set that
are also elements of other
according to other.contains
.
final characters1 = <String>{'A', 'B', 'C'};
final characters2 = <String>{'A', 'E', 'F'};
final intersectionSet = characters1.intersection(characters2);
print(intersectionSet); // {A}
Implementation
Set<E> intersection(Set<Object?> other) {
Set<E> result = SplayTreeSet<E>(_compare, _validKey);
for (E element in this) {
if (other.contains(element)) result.add(element);
}
return result;
}
