[Edapt] Edapt validation for earlier releases [message #1743189]

Hi,

We have several persisted files of our model, but with different versions. There can be several issues with the files (manual updates, while attributes already changed). I need a solution where I could validate the different versions (releases) of these files before the Edapt migration like I can do within a custom migration with model.checkConformance().

Is there any (planned or existing) solution for doing that?

Best Regards,
Balazs

Hi,

I am not sure if I fully understand your problem: When a migration is performed model.checkConformance() is called after the model has been loaded for the first time. As I understood your problem, this is what you want to achieve?

Moreover it is possible to set a different validation level (see org.eclipse.emf.edapt.internal.migration.execution.ValidationLevel) on the migrator with the #setLevel method, so you could tell edapt to check the confirmance after any change.
Also, since a CustomMigration does not have to be attached to any metamodel change, you could also add a check conformance migration at the beginning of every release.

Kind regards
Johannes

Hi Johannes,

Thanks for your reply!
Basically I would like to reach the functionality of the checkConformance() method before the migration is being executed! In this way I could get the list of all the issues within the given file (in an earlier version/release) without migrating it, which would fail right after the first issue.

Kind regards,
Balazs

Hi,
I haven't tested it, but the following should work.
After you have created a Migrator and before starting the migration you can call
org.eclipse.emf.edapt.migration.execution.Migrator.getMetamodel(Release)
The Migrator also offers methods to access the Release you need, e.g. based on a NS-URI.
You can get the NS-URI with org.eclipse.emf.edapt.migration.ReleaseUtils.getNamespaceURI(URI).

Then you can use
org.eclipse.emf.edapt.internal.migration.internal.Persistency.loadModel(URI, Metamodel, IResourceSetFactory)
to get a Model instance on which you can call #checkConformance().

I hope this will help.
Cheers
Johannes

Hi Johannes,

Thank you very much for your help, it is exactly what I wanted to achieve!
The loadModel however might throw MigratorException, what I need to handle, but if it is not causing any issue, I can check the conformance of the old versions as well.

Thank you,
Balazs
