  • Key: QVT11-53
  • Legacy Issue Number: 13268
  • Status: closed  
  • Source: Open Canarias, SL ( Adolfo Sanchez-Barbudo Herrera [X] (Inactive))
  • Summary:

    Problem's text: "the invocation of the operation returns a tuple"
    discussion: it could be understood as an OCL Tuple, which doesn't apply.
    suggestion: Replace "a tuple" by "an ordered tuple".

  • Disposition: Resolved — QVT 1.1
  • Disposition Summary:

    The usage or OrderedTuple seems misguided since an ordinary OCL Tuple does very similar things
    without a positional hazard and without noticeable lexical overhead.
    Only the case of TupleLiteralEx/UnpackExp is plausibly defined in QVT 1.1 and neither of the QVT
    implementations (SmartQVT or Eclipse QVT) support OrderedTuple.
    Therefore eliminate TupleLiteralExp, UnpackExp and OrderedTupleType and
    Note that there are no editing instructions for the grammar. It is not clear that OrderedTuples were
    really supported at all.
