Re Enable Transactions after using trans_off()

To disable database transactions at run-time you can call

PHP Code:

$this->db->trans_off(); 


Maybe I am missing something but I don't see any way to reverse this call to allow transaction processing.

The abstract class DB_driver defines trans_off() with this code.

PHP Code:

public function trans_off()
{
    $this->trans_enabled = FALSE;
} 


The property $trans_enabled is used throughout the class to allow (or not) class methods to proceed. For instance

PHP Code:

public function trans_start($test_mode = FALSE)
{
 if ( ! $this->trans_enabled)
 {
 return FALSE;
 }

 return $this->trans_begin($test_mode);
} 


The "issue", if there is one, is that the documentation at Enabling Transactions implies that calling $this->db->trans_start(); will re-start transaction processing after a call to $this->db->trans_off(); But that is not the case as the code snippet above clearly illustrates.
