Re: [mdt-papyrus.dev] emf validation in Papyrus

Hi all,

In order every Papyrusers could benefit your advices and interesting discussion, it would be nice to switch to the Eclipse forum for Papyrus: http://www.eclipse.org/forums/index.php?t=thread&frm_id=121

Thanks,
Cheers... Sébastien.

Dear Nicholas,

this is quite simple: just follow the tutorial in
http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse.emf.validation.doc/tutorials/validationTutorial.html
for batch constraints. It is necessary to create a ClientContext, the 
selector class could for instance just check whether the passed element 
is a UML model element, e.g.

public class ValidationDelegateClientSelector implements IClientSelector {
     /**
      * Queries whether to select the specified object, which indicates 
that it
      * belongs to this client context.
      *
      * @param object a model element of some kind
      * @return <code>true</code> if the <code>object</code> matches my 
client
      *     context; <code>false</code>, otherwise
      */
     public boolean selects(Object object) {
         return (object instanceof Element);
     }
}

Once registered, your constraints should be checked and lead marked 
model elements within Papyrus.

Best regards

Ansgar
