Summary

A Generalization must be created between two model elements of the same type, except in the case of a Signal, which can specialize a Signal or a Class.

Details

A Class inheriting from a UseCase or a Node inheriting from an Artifact for example would not make sense.

The only exception is for Signals that can inherit from Classes.

Tips

  • Remove your generalization.
  • Change its source or target in order to link two compatible elements.
