An Ada package would correspond to a package that contains classes (i.e. types). Classes can be assigned to components. If you are using Rose, create a category (package that contains classes) that corresponds to the Ada package, and put the package's types as classes within it. Then assign those classes to a component in your component view. You could also create a subsystem (a package that contains components) if appropriate. -- Cheers, The Rhythm is around me, The Rhythm has control.

Then assign those classes to a component in your component view. Whoops, forgot about the nesting. Nested packages can be modelled directly by nesting the categories. Again, the classes can be assigned directly to the component. The component usually corresponds to the source file with the implementation, and does not indicate the nesting directly. Rather, the nesting is indicated in the class diagrams. If you really want to show the nesting in component diagram (especially for child packages where they are in different files), create a subsystem for each package, nested accordingly. Also create a corresponding component to describe what types (i.e. classes) are in each package. E.g for these packages: package Root is type Root_Class is ... end Root; package Root.Child is type Child_Class is ... end Root.Child; Create these components and subsystems: Root\ Root.ada <-- Root_Class is assigned to this component Child\ Root_Child.ada <-- Child_Class is assigned to this component The logical view would have these categories and classes: Root\ Root_Class Child\ Child_Class -- Cheers, The Rhythm is around me, The Rhythm has control.

COOL:Jex) does not allow nesting of UML packages, and if we had used a subsystem per package, well, it would have been a nighmare. I don't know how it would have turned out if we had used Rose. We have been representing nested and child Ada packages as classes that are "a part of" the root class (Ada package). We went with mapping classes to Ada packages. Our system is really object based, not object oriented. I really like UML, but it can be difficult to capture some Ada concepts in it. --djk email not spam to the name given above but at the AOL domain. ^ permalink raw reply [flat|nested] 5+ messages in thread

This seems to me to be a unnecessary and irritating limitation. Hierarchical namespaces are a critical ability for any large system, especially when mapping to a language like Ada that has it. At any rate, Object Team is not adhering to the UML standard. A package is explicitly specified as a namespace that can contain, among other things, sub packages. I suppose you can "fake" by naming your packages with a dot syntax, e.g. Root, Root.Child, etc, but things just compose better with true hierarchies, especially considering visiblity to parent names, etc. Of course, your solution works too. -- Cheers, The Rhythm is around me, The Rhythm has control.
