Adds an answer for an ordering question.
Adds an answer for an ordering choice question. The students have to fill in an order for the answer. The answer is an ASS_AnswerOrdering object that will be created and assigned to the array $this->answers.
- Parameters:
-
string $answertext The answer text double $points The points for selecting the answer (even negative points can be used) integer $order A possible display order of the answer integer $solution_order An unique integer value representing the correct order of that answer in the solution of a question public
