public function DatabaseTransaction::rollback in Drupal 7

Rolls back the current transaction.

This is just a wrapper method to rollback whatever transaction stack we are currently in, which is managed by the connection object itself. Note that logging (preferable with watchdog_exception()) needs to happen after a transaction has been rolled back or the log messages will be rolled back too.
