Returns a reference to the order by array for this query.

Because this method returns by reference, alter hooks may edit the order-by array directly to make their changes. If just adding additional ordering fields, however, the use of orderBy() is preferred.

Note that this method must be called by reference as well:

$fields =& $query->getOrderBy();

Return value

A reference to the expression array structure.
