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 getMessageDeliveryMode([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 setMessageDeliveryMode([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
The delivery mode of the message.
This property holds the delivery mode of the message; possible values are:
- 0: Unspecified.
- 1: Non-persistent; the message may be lost if the server encounters an error.
- 2: Persistent; the message will not be lost, even in case of server errors.
The default is 0, which indicates that the message does not have an explicit delivery mode set.
This property is not available at design time.
