FUML13 — Base semantics: incorrect description of empty-output-parameter-node

  • Key: FUML13-3
  • Legacy Issue Number: 15383
  • Status: closed  
  • Source: Model Driven Solutions ( Mr. Ed Seidewitz)
  • Summary:

    In the fUML 1.0 beta3 document (ad/2010-03-14), Subclause, it states that:

    The empty-output-parameter-node relation ensures executions of expansion region action (the xac variable) transfer values from an output parameter node of the executions of the constructed activity (xcall) to the corresponding output pin of the expansion region (op). It assumes output pin multiplicity upper (opmax) is one or unlimited. This does not put null tokens in output pins when output parameter nodes are empty, as in UML.

    The final sentence is no longer consistent with the fUML operational semantics given in the execution model, which was updated by the resolution of Issue 14550 to offer a null token from an output pin if it holds no values when it fires.
