Re: [uml2-dev] Extending UML2

Martin,

Please direct future questions like
this to the newsgroup, as this mailing list is reserved for UML2 development
issues.

The "discouraged reference"
compiler warnings (which can be disabled) are coming from the fact that
the UML2 implementation classes are marked internal, and aren't really
meant to be extended.

To address the errors, you'd need to
use the custom code generator provided in UML2 1.1 (there are a number
of conventions in UML 2.0 that EMF doesn't handle very well by default).
Note however, that only Rose (via the org.eclipse.uml2.importer.rose plug-in
that can be obtained from CVS) and UML2 models are currently supported
as source formats for the UML2 code generator, so you'll have to model
your extension rather than just expressing it in Java.

Cheers,

Kenn Hussey

Subject	[uml2-dev] Extending UML2

This is my first message to this mailing list, so perhaps
this has been answered before. My apologies if that\'s the case.
I\'m trying to implement a UML2-like component diagram editor using GEF
and org.eclipse.uml2. I say uml-like because it would include some non-uml
features, more exactly the concept of responsibilities associated to components.
Exploring the metamodel, I found BehavioralFeature could be a good place
for Responsibility to extend from.
To extend BehavioralFeature, I did the following:
1. Associated my project to the imported (with source) uml2 project
2. Added uml2 as a dependency to plugin.xml
3. Created the following interface:
/**
* @model
*/
public interface Responsibility extends BehavioralFeature {
}
4. Imported the annotated interfaces to create an ecore model and a generator
model
5. Generated the model code

Now, the whole process doesn\'t produce any error messages, but the generated
code has many \"discouraged reference\" warnings and compilation
errors for undefined references in the generated code. For instance, eInverseAdd()
has references to an \"owner\" field and a \"basicSetOwner()\"
method that are not defined anywhere. It\'s obvious that I didn\'t get
something right, but I\'m having a hard time trying to figure out what
it is exactly. Any ideas/suggestions on how to extend the uml2 metamodel
for my purposes?
Thanks in advance,

Martin Blech
