Checkout():Void

In order to be able to edit a data object in onion.net, the editing process for the data object to be edited must be reserved for the user. The method Checkout carries this out for the user of the current session. The data object is then "checked-out" for the user and the user can edit the content of the data object.

If the data object has already been checked out, the exception DataObjectCheckedOutException is triggered.
