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 getSerialNumber([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 setSerialNumber([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

If this element is present when submitting a Card Range Request (CRReq) with the RequestCardRanges method, the Directory Server returns card ranges that have been updated since the time of the response which returned this serial number. If the element is not present, the Directory Server returns all participating card ranges. This field is updated with a new serial number after each call to RequestCardRanges.
