I would like to know how can I get java code from .ecore metamodel (in this case from atl.ecore) like it's possible, for example, with UML.

Thanks.

Hi

Your English is very ambiguous. Try saying what you want more clearly.

This isn't a question that has a general answer. E.g., if I have an
Ecore model for Library or Person, and I have an instance of that, how
is that instance supposed to be mapped to Java? For UML specifically,
there is an importer that will map UML instances to Ecore instances and
from Ecore you can of course generate Java code.

Thanks for the replies. I would like to generate Java code from Ecore instances, in concrete from ATL.ecore

Hi

This still makes no sense to me.

ATL.ecore is a model so the ATL project already provides Java code for it.

You can of course generate your own versions.

If you want a direct Java expression of the ATL code then I think you
may have to wait a few years.

But since I don't know what you mean by Ecore instances, may be you
want something else altogether.

Actually I'm not sure if the ATL metamodel is generated using EMF. It might only be used using dynamic EMF.

What I'd like is to instantiate a ecore model in java. If you say that already exists for ATL.ecore where could I find it?

Perhaps you mean Java code like this:

EAttribute assignee = EcoreFactory.eINSTANCE.createEAttribute();
assignee.setName("assignee");
assignee.setEType(EcorePackage.eINSTANCE.getEString());
assignee.setDefaultValueLiteral(DEFAULT);
assignee.setUnsettable(true);

EClass bugzilla = EcoreFactory.eINSTANCE.createEClass();
bugzilla.setName("Bugzilla");
bugzilla.getEStructuralFeatures().add(assignee);

EPackage p = EcoreFactory.eINSTANCE.createEPackage();
p.setName("p");
p.getEClassifiers().add(bugzilla);

So follow the tutorial, but use a "Ecore model" as the source of your
model in step 1.

I followed this tutorial -> http://eclipsesource.com/blogs/tutorials/emf-tutorial/ and for the ATL example "HelloWorld" it works fine and has everything I wanted/expected. The problem is when I'm doing the same but using this time ATL.ecore. I'm receiving this errors when I try to load the ecore model:

I can keep going besides this errors and the .genmodel file is generated, but the options for generating the java code are no longer available in this way.

Pedro,

You can ignore this error (and the ATL folks should fix it). Note the
Generator editor has tabs in the bottom, and this page showing these
errors in only one of the tabs. You can go back to the other tab to
access the GenModel.

Thanks for your reply!

I know that besides this errors the model can be generated, but the problem is the option for "Generate Model Code" are no longer available because of this errors.

Here is a picture to exemplify what I'm saying:

Doesn't the second 1/2 of the sentence contradict the first 1/2?

Why does this picture show a model with that menu option enabled?

So the *.genmodel is created? But when you open the editor you see the
error you've shown? And you've located the tabs at the bottom of the
editor that I mentioned. And you can turn to the first tab? That
context menu has disabled menu options?

You are right! Since the error was appearing when I was opening with "EMF Generator", I assume that the file couldn't be open, so I was opening with " Sample Ecore Model Editor" and obviously the generation option wasn't there.
Now I follow what you said and just change the tab and I was able to generate the code.

Thanks a lot for your help.
