FUML13 — Prose for semantics of AddStructuralFeatureValueAction required

  • Key: FUML13-18
  • Legacy Issue Number: 19866
  • Status: closed  
  • Source: Fraunhofer FOKUS ( Marc-Florian Wendland)
  • Summary:

    UML 2.5, section Add Structural Feature Value Actions says:

    "The semantics are undefined for adding a value that violates the upper multiplicity of the StructuralFeature, and for
    adding a new value to a StructuralFeature with isReadonly=true after initialization of the object that would have the

    In fUML, this undefined semantics is resolved. Values are simply added to the StructuralFeature of the target object. This semantics is also described in the implementation of AddStructuralFeatureValueActionActivation.doAction() (section, pp. 298).

    Since this implementation represents the resolution of an undefined semantics of the UML specification, section AddStructuralFeatureValueAction should add a prose description of this resolution to its "semantics" clause. It would increase the readability and comprehensibility of the spec.

  • Disposition Summary:

    Add note on AddStructuralFeatureValueAction

    Agreed, in principle. However, in the fUML specification does not have a "semantics clause", because it is in the clause on abstract syntax, not semantics. Instead, a note should be added under "Structural Feature Actions" in, the Overview for Intermediate Actions. Also, currently, the UML specification reference still needs to be to the UML 2.4.1 Superstucture Specification.
