      • bind

        public void bind​(Activator activator)
        Description copied from interface: Activatable
        Called by db4o after the object instantiation. This method is called to bind the object to the current activator

        The recommended implementation of this method is to store the passed Activator in a transient field of the object.

        activator - the Activator instance to bind
