Overview

Slave class used by Versioner class to load and store migrated files inside the CM. It uses separate object type named “version_store” and stores data as base64’ed YAML inside recordSetCallback (Versionszuweisungsfunktion). Theoretically you could use any class for this purpose, but you would lose the ability to set recordSetCallback for this class. Other than that, it does not affect the object class in any way!

Maybe the future version won’t disrupt even this fuction.
