Syntax

 gdrive.setChangeMarker( changeMarker, [callback])

Default Value

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 getChangeMarker([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 setChangeMarker([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 returns a marker used to iterate over pages of changes. When ListChanges is called, if the results are paged this property will be populated. Continue to call ListChanges until this property returns empty string in order to list all changes.

This property is not available at design time.
