Hi,

I am creating ecore at run time and i am able to save .ecore file successfully. I would like to generate .oclinecore file programmatically as well.

Once i have tried things like
OCLinEcoreDocumentCS document = Ecore2OCLinEcore.importFromEcore(resourceSet, "test", resource);

now i have updated all components in my eclipse so OCLinEcoreDocumentCS seems missing as well as Ecore2OCLinEcore.

i am trying to explore org.eclipse.ocl.examples.xtext.oclinecore.utilities.OCLinEcoreCSResource as well.

do you have any idea how i can generate .oclinecore programmatically?

thanks!

cheers

Hi

You should be able to find all classes using the Type Hierarchy.

However the CST is not public API so it is likely to change.

If you really want to auto-generate, much better to auto-generate
- the AST, either Pivot or Ecore
- the text

and if you really want the CST you can use one of the concersion
routine. But if you really want the CST, I think you should revisit your
design.

Sorry i did not understand you..

I just want to generate text from my ecore model. I think Pivot2CS class might be the one i am looking for.

I have tried following

OCLinEcoreStandaloneSetup.doSetup();
Injector injector =OCLinEcoreStandaloneSetup.getInjector();
ResourceSet csRS = injector.getInstance(ResourceSet.class);
Resource r = csRS.createResource(uri1.trimFileExtension().appendFileExtension("oclinecore"));

r.getContents().add(modelPackage);
r.save(null);

and i am getting following exception

java.lang.RuntimeException: The context 'RootPackageCS' is not valid for type 'EPackage'
Recommended contexts for type 'EPackage':
The context 'RootPackageCS' is valid for types: RootPackageCS

Semantic Object: EPackage'temp'
at org.eclipse.xtext.serializer.diagnostic.ISerializationDiagnostic$ExceptionThrowingAcceptor.accept(ISerializationDiagnostic.java:70)
at org.eclipse.ocl.examples.xtext.oclinecore.serializer.AbstractOCLinEcoreSemanticSequencer.createSequence(AbstractOCLinEcoreSemanticSequencer.java:672)

i hope i am not creating more confusion.

thanks!

Hi

If you want text then you need

EcoreXMI->EcoreAST->PivotAST->PivotCS->XtextNodes->text

for which the various converters and loaders are all available. Look at
the SerializeTests.

Hi

This information is all availabvle on the OCL project page:
http://projects.eclipse.org/projects/modeling.mdt.ocl

and in the Wiki.

The serialization tests are in the exaamples tests plugin.

Please use a little initiative.

Regards
