示例1: insertUpQueueEntry

{

  ex_queue_entry *upEntry = qParent_.up->getTailEntry();

  ExFastExtractPrivateState &privateState = *((ExFastExtractPrivateState *) downEntry->pstate);

  // Initialize the up queue entry.
  //
  // copyAtp() will copy all tuple pointers and the diags area from
  // the down queue entry to the up queue entry.
  //
  // When we return Q_NO_DATA if the match count is > 0:
  // * assume down queue diags were returned with the Q_OK_MMORE entries
  // * release down queue diags before copyAtp()
  //
  if (status == ex_queue::Q_NO_DATA && privateState.matchCount_ > 0)
  {
    downEntry->setDiagsArea(NULL);
    upEntry->copyAtp(downEntry);
  }
  else

    upEntry->copyAtp(downEntry);
    downEntry->setDiagsArea(NULL);
  }
