FUML12 — ListFunctions should have a ListConcat behavior

Open Closed All

  • Summary:

    Specification: Semantics of a Foundational Subset for Executable UML Models (fUML), v1.1, RTF Beta (ptc/2012-10-18)
    Subclause: 9.2.6 List Functions

    The FoundationalModelLibrary::PrimitiveBehaviors::ListFunctions currently includes only ListGet and ListSize behaviors. However, given only these functions and the other capabilities in fUML, it is very difficult (if not impossible) to concatenate two arbitrary lists. The ListFunctions package should have a primitive ListConcat behavior to perform this function.

  • Disposition Summary:

    Add ListFunctions::ListConcat

    It actually is possible to implement a ListConcat activity, using two "pass-through" structured activity nodes connected by a control flow, which sequentially feed the two lists to be concatenated to a merge node. However, this is certainly not a particularly natural construction. ListSize and ListGet could also actually be implemented using expansion regions/loop nodes (as currently noted in the spec), but it is still more useful to have them as primitive functions. The same is true of ListConcat.
