intersection method

Set<E> intersection (Set<Object> other)

override

Returns 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.

Implementation

Set<E> intersection(Set<Object> other) {
  Set<E> result = SplayTreeSet<E>(_comparator, _validKey);
  for (E element in this) {
    if (other.contains(element)) result.add(element);
  }
  return result;
}
