Join & disjoint definition in Class diagram


I have tried to disjoin and join in the class diagram, but I have not found how to do this. I have also seen that the subclass can not mark as complete or incomplete. ¿Someone can tell me if this is possible and how can I do?


Hi user,

Thanks for your message. Are you talking about the constraint of GeneralizationSet, which is mentioned in page 76 of UML Superstructure Specification v2.1.2 (as shown in image)?
If so, I’m sorry that these are not available since we do not support GeneralizationSet.

Best regards,
