Hi,

I see there exists an article that explains how to insert restrictions
OCL in the EMF MetaModels. The article is this one:
http://www.eclipse.org/articles/Article-EMF-Codegen-with-OCL /

But it works only in Eclipse Europa, tha uses a different version of EMF
than Eclipse Ganymede, so this article is not valid now.

Anybody know how to insert restrictions in the MetaModel?

I have seen a new article in the eclipse wiki
( http://wiki.eclipse.org/EMF/Validation/Recipes#Recipe:_HowTo _use_the_Eclipse_Validation_Framework_with_OCL_constraints_d efined_in_a_separate_file
), but it's not the same I want. This article explains how to add
restrictions in a separated OCL file, and references this file throught
an Extension in the plugin.xml

Thanks.
Marc

Hi Marc,

I believe that the associated JET templates must be tailored to make the
example work in Ganymede and Galileo releases.

I encourage you to send a new enhancement request
( https://bugs.eclipse.org/bugs/enter_bug.cgi?product=MDT& bug_severity=enhancement)
so that it could be considered and planned by the OCL team ;)

Cheers,
Adolfo.

Hi Adolfo, I have sent the bug:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=270974

I try these templates in Eclipse Ganymede, and no code is generated in
the model. The classes are empty.

In Eclipse Europa, the templates work ok.

Thanks.
Marc Gil

Great !!!

Just one question, why do you say that specifying the constraints in a
separated file is not what you want ?. I believe that you must obtain
the same result. Moreover, I think that writing OCL constraints should
be more pleasant for the user if he/she uses a high quality OCL Editor.
I imagine that writing those constraints as EAnnotations can't be very
user-friendly...

Cheers,
Adolfo.

Hi Adolfo,

The main reason is for having all the constraints in only one file, the
MetaModel. With this solution, if you have only the MetaModel, you don't
know which are the constraints if you don't has this file. It's a way to
have the MetaModel and the constraints in centralized.
