UML23 — UML 2 Super / Components / realizingClassifier

  • Key: UML23-148
  • Legacy Issue Number: 8385
  • Status: closed  
  • Source: Simula Research Laboratory ( Bran Selic)
  • Summary:

    InterfaceRealization is a subclass of Realization that inherits the attribute Realization::realizingClassifier (defined in the Components package). This attribute has a multiplicity of 1, which means that InterfaceRealization must have a "realizingClassifier", even though this attribute only makes sense when the target is a Component and not an Interface. This is complicated further by the fact that InterfaceRealization has its own association end that serves a similar purpose called "implementingClassifier". But, this only makes sense for the case when the target of the realization is an Interface and not a Component.

    InterfaceRealization should not be forced to have a "realizingClassifier" attribute. The best way to fix this may be to define a separate subclass of Realization for the case of Components (e.g., ComponentRealization) such that the two cases are kept apart. Alternatively, the multiplicity on Realization::realizingClassifier could be set to 0..1.
