Generating code with OCL constraints etc.. in it [message #227580]

No to sure if this is the correct place to post, please redirect me if
I'm wrong.

I'm working on a project in RSA 7.5.1 and defining OCL constraints
there. I'm wanting to generate Java code that has these constraints in
it. Currently I'm mucking about with creating an EMF Gen Model from a
UML 2.1 export of the RSA emx file.
The gen model looks OK as far as I can tell... However when I generate
the model code, I just get a bunch of "TODO: implement this method" in
the code :(

I've done some digging around, looks like the couple of guides I've
found recommend turning on dynamic templates in the gen model and
creating custom JET templates that insert the ocl constraints into the code.

I'm just wondering is this the current 'best' way to do this? I would of
expected that there would be a canned solution to this problem? i.e. The
OCL project provide a set of templates for EMF->Model generation....

Any clarification the state of things will no doubt be quite enlightening :)

Hi RefuX,

You may want to have a look at the OCL section at the bottom of the
following:
http://www.eclipse.org/modeling/mdt/uml2/docs/presentations/ EclipseCon2008_LongTalk_NewFeaturesOfUML2_files/frame.htm

Regards,

Thank you!

Was just needing to set 'Operation Bodies' to Process on the EMF Gen
Model UML import.

I also updated my UML model to use ECORE data types
( http://sdqweb.ipd.uka.de/wiki/Creating_EMF-Models_with_RSA#U sing_ECORE_data_types),
so I could switch some of my 'primitive' data types to ecore ones.
Generated like a charm, not a red x in sight.

Haven't actually tried creating instances of the objects yet, but it
looks good :)
