示例1: rollback_delegated_transaction
/**
* Call when delegated transaction failed, this rolls back
* all delegated transactions up to the top most level.
*
* In many cases you do not need to call this method manually,
* because all open delegated transactions are rolled back
* automatically if exceptions not caught.
*
* @param moodle_transaction $transaction An instance of a moodle_transaction.
* @param Exception|Throwable $e The related exception/throwable to this transaction rollback.
* @return void This does not return, instead the exception passed in will be rethrown.
