Validating an EMF model programatically [message #622929]

Hi everyone, I posted this question a couple of days ago in the UML forum but it seems that I should have used the EMF newsgroup instead, so I'm just moving the 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.

Hi,
it should work like this:

YourValidationClientSelector.setRunning(true);
IBatchValidator validator = (IBatchValidator)
ModelValidationService.getInstance().newValidator(Evaluation Mode.BATCH);
validator.setIncludeLiveConstraints(true);
IStatus status = validator.validate(object);
ValidationClientSelector.setRunning(false);

Furthermore I would look into the existing handler of the editor...
Cheers
Jonas
