PHP question_attempt_step::set_state方法代碼示例

 /**
  * Start this question attempt.
  *
  * You should not call this method directly. Call
  * {@link question_usage_by_activity::start_question()} instead.
  *
  * @param string|question_behaviour $preferredbehaviour the name of the
  *      desired archetypal behaviour, or an actual model instance.
  * @param int $variant the variant of the question to start. Between 1 and
  *      $this->get_question()->get_num_variants() inclusive.
  * @param array $submitteddata optional, used when re-starting to keep the same initial state.
  * @param int $timestamp optional, the timstamp to record for this action. Defaults to now.
  * @param int $userid optional, the user to attribute this action to. Defaults to the current user.
  * @param int $existingstepid optional, if this step is going to replace an existing step
  *      (for example, during a regrade) this is the id of the previous step we are replacing.
