UML23 — Currently is it possible for a Classifier to specialize the same classifier directly more than once

Open Closed All
  • Key: UML23-79
  • Legacy Issue Number: 14035
  • Status: closed  
  • Source: Oracle ( Dave Hawkins)
  • Summary:

    Currently is it possible for a Classifier to specialize the same classifier directly more than once, that is, generalization.general contains duplicates. There should probably be a constraint to make this invalid.
  • Reported: UML 2.2 — Mon, 29 Jun 2009 04:00 GMT
  • Disposition: Resolved — UML 2.3
  • Disposition Summary:

    This seems harmless. Also, there might be scenarios where the same pair of classifiers are related by more than one
    generalization each associated with different GeneralizationSets. Prohibiting this might also invalidate existing models
    unnecessarily.
    Disposition: Closed - No Change
