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 getObjectsETag([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 setObjectsETag([callback]) method is defined as:

'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 ETag of the object.
This property reflects the ETag of the object.
An object's ETag is an MD5 hash of its contents, and as such can be used to determine if its contents have been modified.
The index parameter specifies the index of the item in the array. The size of the array is controlled by the ObjectsCount property.
This property is read-only and not available at design time.
