FUML_ — Values passed out to pins from empty parameter nodes

  • Key: FUML_-1
  • Legacy Issue Number: 14990
  • Status: closed  
  • Source: NIST ( Mr. Conrad Bock)
  • Summary:

    In UML empty parameter nodes are currently given the null value when an
    activity terminates. The semantics of ActivityParameterNode says: "If
    some output parameter nodes are empty at that time [when the activity is
    finished], they are assigned the null token, and the activity

    If it is decided that the execution engine should not reflect the above
    semantics, then UML needs an additional attribute on
    ActivityParameterNode to indicate whether null tokens are passed out to
    pins when the activity is finished executing and the activity parameter
    node is empty, or whether nothing is passed out. In ExecUML this
    attribute value would always be for the second option.
