SYSML17 — The NoBuffer specification makes a wrong statement about the UML semantics

  • Key: SYSML17-492
  • Status: open  
  • Source: Airbus Group ( Yves Bernard)
  • Summary:

    The sentence that says: “When the stereotype is not applied, the semantics are as in UML, specifically, tokens arriving at an object node that are refused by outgoing edges, or action for input pins, are held until they can leave the object node” is false. This is not the semantics UML specifies. Buffering is provided only for token satisfying the guard but that are not numerous enough to satisfy the “weight” condition.
