Destroy():Void

This method can delete a version for a data object.

In order to be able to delete versions, the user must have the role of administrator.

Furthermore, a version can be only deleted if this version can no longer be the most up-to-date version of the data object. Versions that cannot be deleted are on the one hand the current version, and if a data object is checked out, then the previous version can equally not be deleted. For if the changes to the checked out data object are discarded, then the previous version becomes the current version.
