Hi,

How can I get the addresses of input model and input metamodel in eol program?
I want to pass these addresses to java.

Hi,

If you're using an EMF-based named M you can get its path using M.getResource().getURI(). If you're using a file-based metamodel for it you can use M.getMetamodelFiles().

Thanks a lot.
Is it also possible to use Aliases for Metamodel? e.g., Is something like "IN_MM!EPackage.allInstances() -> first()" true?

As another question, I created a model in my eol program. Then I pass the URI of the model as you said to java. However, before the contents of model is completely loaded the java function runs. It causes the java function works with empty model and get error. What should I do?

and also how can I check the model is empty or not?

I'm not sure what you're trying to achieve but give this a go and see what happens.

Please attach a minimal example [1] I can use to reproduce the behaviour you're encountering.

Using eclipse Mars.2 (4.5.2) on mac os x.
epsilon 1.3
import Test plugin to eclipse. run it as eclipse application. In the new eclipse, import test1 project and run it.

Thanks for your time.

I have also another question. When I pass the EPackage of metamodel from Epsilon to Java, how can I register it?

Hi,

If you need to register it in the global EPackage Registry, EPackage.Registry.INSTANCE.put(...) should do the trick.

I think that you're missing an r.load(...); after Resource r = rs.getResource(path, true); in your Test1 method.

I'm sorry. It sometimes works correctly and many times works incorrectly.
Do you have any idea?

I'd start by finding a subset of the program that can be used to consistently reproduce the problem you're encountering.

It seems if I pass the "Resource" instead of "URI" the program works correctly.
Thanks.
