[news.eclipse.modeling.m2m] Re: [ATL] Launching (EMF) ATL programmatically and allow inter model references
By luck, I found the following thread [1]. It tells that the options should be pass to the ILauncher.launch call! The option must be a String (and not a Boolean). The option's name starts with a lower-case 'a'.

options.put("allowInterModelReferences", "true");
final Object result = launcher.launch(ILauncher.RUN_MODE, new NullProgressMonitor(), options, asmURL.openStream());

Hi,

I'am trying to make a plugin that contains an ATL transformation. By now I am able to get the resulting file but it does not contains intermodel references. Obviously I tried the option allowInterModelReferences but I cannot get it working...

First, is the name of the option contained somewhere in a static field? org.eclipse.m2m.atl.adt.launching.AtlLauncherTools is not in Galileo, does it?

Second, is it the same option name if I am calling method (EMF)Resource.save?

Do you need to pass it to the ATL Launcher (also it's not working)?

Do you need to put a Boolean or a string value (neither work)?

Here is what I think is the interesting code. Note that normally I use the EMF ATL VM hence I always get an EMFModel as a result.

public static Resource toXxResource(final IResource yyModelResource)
      throws ATLCoreException, IOException {
  // This is the basic call
  IModel outputModel = toXxModel(yyModelResource);
  // Now try to serialize the result
  URI outputURI = URI.createURI(yyModelResource.getLocationURI()
          .toString().concat(".xmi"));
  final Map<String, Object> options = new HashMap<String, Object>();
  options.put("allowInterModelReferences", Boolean.TRUE);
  options.put("AllowInterModelReferences", Boolean.TRUE);
  if (outputModel instanceof EMFModel) {
    EMFModel emfModel = (EMFModel) outputModel;
    Resource res = emfModel.getResource();
    assert res != null;
    ResourceSet set = res.getResourceSet();
    assert set != null
    OutputStream outputStream = set.getURIConverter()
            .createOutputStream(outputURI);
    res.save(outputStream, options);
    res.setURI(outputURI);
    assert res.getURI().equals(outputURI);
    return res;
 } else {
    IExtractor extractor = CoreService.getExtractor("EMF");
    extractor.extract(outputModel, outputURI.toString(), options);
    return null;
  }
}
