func formInserts the elements of another set into this option set.
func insert(DispatchAdds the given element to the option set if it is not already a member.
func intersection(DispatchReturns a new option set with only the elements contained in both this set and the given set.
func isReturns a Boolean value that indicates whether the set has no members in common with the given set.
