[news.eclipse.tools.uml2] Re: correct mapping of a dynamic simulation mo

["James Bruck" <jbruck@xxxxxxxxxx>]

Hi Axel,

Consider CallOperationAction.   CallOperationActions refer to an operation
of a Class.  They own InputPins that correspond to parameters of the
operation and
OutputPin's that correspond to the return parameter.
I think you can show what you want using InputPins and OutputPins.  You can
use ObjectFlow's between the pins.
You seem to be on the right track with Activity Diagrams.

Alternatively, if you want to model the structure of a certain structured
classifier you can consider using Composite Structure Diagrams.   You can
model properties using parts or roles and connect them using Connectors.
Ports are also useful for modeling interaction points on structured
classifiers.

If you want to convey how a group of associated parts contribute to
accomplish one particular task you might consider creating a collaboration
with roles in it's structure diagram and show how the roles are
inter-connected.

Sequence diagrams could also be of some use if you want to model general
instances or specific instances ( a particular run ) of executing code.

Creating a profile and stereotypes would be a final step if you have
concepts specific to your domain that you wish to emphasize.  ( Keep in mind
that you could just use keywords as a "ultra-light weight" way of
emphasizing your concepts. )

... a little vague but I hope this helps....

Cheers,

- James.
