UseJournaling Property

Whether the class should open a vault in journaling mode.

Syntax

 cbdrive.getUseJournaling([callback])
 cbdrive.setUseJournaling( useJournaling, [callback])

Default Value

FALSE

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getUseJournaling([callback]) method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

The callback for the setUseJournaling([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This property specifies whether the class should open a vault in journaling mode, which will cause it to make use of transactions to help protect data integrity.

Please refer to the Vault Corruption topic for more information about how journaling and transactions work.

Note: This property cannot be changed when Active is true, and cannot be changed within events.

Data Type

Boolean
