OCL25 — Inconsistent OclVoid::oclAsType return

Open Closed All
  • Key: OCL25-198
  • Legacy Issue Number: 19750

  • Summary:

    7.4.6 states: If the actual type of the object, at evaluation time, is not
    a subtype of the type to which it is re-typed, then the result of oclAsType is invalid.

    7.5.8 states: self.oclAsType(A).p1 – accesses the p1 property defined in A - this is incompatible with the no-class-change-to-A so A::p1 is not available for null.

    But the normative 11.3.2 states: oclAsType(type : Classifier) : T
    Evaluates to self.

    The OCL 2.4 contribution to 11.3.2 was a typo. It should be "evaluates to invalid".
