Re: [uml2-dev] Introspecting subsets features..

[Kenneth Hussey <khussey@xxxxxxxxxx>]

Stephane,

The UML2 newsgroup is at news://news.eclipse.org/eclipse.tools.uml2.
A link to it is available from the UML2 home page.

Unfortunately, since EMF does not directly
support the concept of subsets/supersets, there is no metadata containing
this information at runtime. Annotations exist in the source model (that's
how the custom code generator knows which features are subsets), but the
runtime metadata is instantiated from generated code which does not take
annotation references into account. This may improve in UML2 2.0, however,
since it is likely that the metadata will instead be loaded from a file...

Cheers,

Kenn Hussey

Subject	[uml2-dev] Introspecting subsets features..

Sorry I can't find any UML2 newsgroup on http://www.eclipse.org/newsgroups/index.html...


Hi all, my name is Stephane (PARIS)

How to know when a feature is a subset of an an other?? I mean f.e.:

UML2Package.eINSTANCE.getBehavioralFeature_FormalParameter()

Is subset of :

UML2Package.eINSTANCE.getOperation_OwnedParameter()


So how can I know it on runtime when I have those two features instances??.

I need to know that because I'm filtering notifications depending on which
features has been changed....

I tryed to introspect EAnnotations on metamodel (UML2) but it doesn't work:

UML2Package.eINSTANCE.getOperation_OwnedParameter().eAnnotations().....getReferences()
is EMPTY...


I also tryed to find any clue on featureIDs but I can't find any...

so please help me...

THANK YOU...

Stephane.
