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 getFileData([callback]) method is defined as:
function(err, buffer){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'buffer' is the value returned by the method.
The callback for the setFileData([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 Filename is specified BuildFile will save to disk, and FileData will remain empty. However if Filename is blank, the file will be created in-memory and stored in this property.
This property is read-only.
