UML14 — Interface must also have features

  • Key: UML14-805
  • Legacy Issue Number: 1324
  • Status: closed  
  • Source: Anonymous
  • Summary:

    Summary: Page 16 If Classifiers have features (e.g. attributes and methods) then an
    Interface must also have features since it is a kind of Classifier. Yet,
    on page 24, it is stated that an Interface has operations only; on page 37
    Notation document it clearly states Interface "lacks attributes". If this is
    done by an OCL constraint, then we have a negation of properties of the
    subtype which Brachman points out to be dangerous.
