Yes, maybe. But we should at least make the id() a derived property for Mesh. We can put the unique_id member variable and the id member function in a separate class named "ID" (or similar). Then Mesh can derive from both Variable and ID. That way, we can easily add the property to other classes when we need it. -- Anders _______________________________________________ Mailing list: https://launchpad.net/~dolfin Post to : [email protected] Unsubscribe : https://launchpad.net/~dolfin More help : https://help.launchpad.net/ListHelp
