public abstract class PersistentObject
extends Object
implements Serializable, Cloneable

This empty class is the common root for all persistent capable classes. If this class inherits from java.lang.Object then all subclasses are serializable with the standard Java serialization mechanism. If this class inherits from com.objy.db.app.ooObj then all subclasses are additionally serializable with the Objectivity ODBMS persistance mechanism. Thus, by modifying the inheritance of this class the entire tree of subclasses can be switched to Objectivity compatibility (and back) with minimum effort.
