public abstract class ObjectToVersionLink
extends WTObject
implements BinaryLink, Externalizable

The ObjectToVersionLink provides a binary type of link between a persistable object (role A) and a version (role B). When used in navigating from the persistable object to its associated version, only the latest iteration is found. Navigating from the version to its associated persistable object acts a typical navigation, but is applicable only from the latest iteration.

Supported API: true

Extendable: true
