Validating an EMF model programatically [message #535591] Mon, 24 May 2010 18:42 Go to next message

I was going over the EMF Validation Framework example and I was able to set everything up and add a few extra constraints. Then I run the plugin as an eclipse application, I create the model and then in the editor menu I can select validate to check the constraints and everything works fine.

But I was wondering if it is possible to validate a model programmatically, without using the editor.

// For example, create a few objects:

Book myBook = EXTLibraryFactory.eINSTANCE.createBook();
myBook.setTitle("EMF Validation");
Writer writer = EXTLibraryFactory.eINSTANCE.createWriter();
writer.setName("Hector");

//And then do the validation

I've been searching the web with no luck. Can something like this be done? I would appreciate any hints.

Thanks.

Diagnostician.INSTANCE can be used to check the core constraints.

I tried using Diagnostician.INSTACE before but it seems that it only checks the default core constraints, which is not useful in my case. I added a couple of custom constraints and those are ignored by the Diagnostician.

To be more specific, I added two ocl constraints on plugin.xml following the format given in the OCL validation tutorial on the eclipse documentation web site. Those constraints are correctly checked when I use the editor->validate, but are ignored by the Diagnostician.

Hi, Hector,

I gather from this thread that you have used the example plug-in's
Validate context menu action to successfully test your constraints. It
serves as an example of how to perform validation using the API: just
look at the implementation of that action. :-)

Hopefully the Programmer's Guide documentation included in the SDK will
be helpful, also.

Finally, this subject is not quite in the scope of the MDT UML2
newsgroup. Any follow-up question that you may have about EMF
Validation should be directed to the EMF newsgroup; indeed, you will
probably find that many of your questions (including this one) have been
asked and answered, there.

HTH,

Christian

Thank you, I didn't think about that, I'll check the EMF newsgroup.
