[news.eclipse.modeling.mdt.uml2.uml] Re: UML Interactions via the API

["James Bruck" <jbruck@xxxxxxxxxx>]

Hi Paul,

Have a look at
http://www.eclipse.org/modeling/mdt/uml2-uml/docs/guides/UML2_2.0_Migration_Guide/guide.html
for a description of the changes between the older and newer versions of
UML.

Some of the metaclasses have been renamed i.e. OccurrenceSpecifications
replace older EventOccurrence's and the metamodel has changed significantly
in the area of interactions.

If you are trying to get an exact sequence of all
ExecutionOccurrenceSpecifications in a sequence diagram,  I don't think the
algorithm below would be sufficient to handle all cases ( there is a long
discussion in previous postings as Kenn has pointed out ).

Hope this helps a bit.

Regards,

- James.
