[EMF Validation] EMF Validation Framework [message #894995] Wed, 11 July 2012 11:15 Go to next message

hi,
During the preparation of my PhD,i'm working on real time design pattern and i'm trying to implement a tool to check validity of pattern instance.
So, I create a constrainte using the EMF Validation framework to check that every class in a pattern instance must have a different name (no duplicated class names). I'm trying to applicate the validation Adapter tutorial but can't achieve any result because I can't find documentation that explain the steps to follow in order to implement constraint using DiagnosticChain interface.

Please help me.

Thank you,

You're reposting essentially the same question. More comments below.

Have you tried adding a named constraint to the Ecore model for this
"pattern instance EClass" as I suggested previously?

The problem is that no one is maintaining the extended validation
framework nor is anyone familiar with it monitoring the newsgroup/forum
to answer questions about it. I can help you get the core validation
support working, but I don't have the resource to help with the extended
validation framework. So you can either try what I suggest or, it
appears, you're basically on your own and will have to figure it out
with what little is available.

I try to apply "validateEPackage_UniqueClassifierNames" constraint,but it does not taken into account in the runtime application!!
I think that the problem is the ePackage parametre because in the instance model all the elements are EClassifier.
What are you saying??

Hi

Depending on the complexity of what you're checking and the efficiency
you need, you might find using OCL or rather OCLinEcore.

Alternatively, recent Papyrus activity has extended EMFv, so you might
try asking on that group.

Wiwa,

If you look in Ecore.ecore, you'll see that EPackage has an annotation
like this

<eClassifiers xsi:type="ecore:EClass" name="EPackage"
eSuperTypes="#//ENamedElement">
<eAnnotations source="http://www.eclipse.org/emf/2002/Ecore">
<details key="constraints" value="WellFormedNsURI
WellFormedNsPrefix UniqueSubpackageNames UniqueClassifierNames
UniqueNsURIs"/>
</eAnnotations>

I'm suggesting you add such an annotation to your model (the EClass for
the pattern instance) and look at your generated validator.
