AppendObject Method

Appends data onto an object on the server.

Syntax

wasabi.appendObject(objectName, [callback])

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 this 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 method will append the content of the file specified by LocalFile into the bucket specified by the Bucket property. If LocalFile is empty, the contents of the ObjectData property will be uploaded instead.

You may only append to an object that already exists. To create a new object, use the CreateObject method.

Note: Appending is a form of object composition, so the same restrictions that apply for object composition also apply when appending to objects; refer to ComposeObjects for more information.
