Hi

How can I have the modell instance of the DSL?
I mean in Runtime eclipse that I have a SDL editor and I write my DSL, How can I access the Modell Instance of the DSL which I have in DSL Editor? I want to compare this instance modell with an instance modell which is created with EMF editor.

Thanx

You can load an Xtext based DSL-file similarly to any other EMF resource. The main difference is that you need to make sure that the language's injector is properly set up and that the EMF registries are populated. In standard Java process you do this using the [MyDSL]StandaloneSetup.

Here is some (untested) code that should get you started.

public static void main(String ... args) {
  // initialize Xtext language
  new MyDslStandaloneSetup().createInjectorAndDoEMFRegistration();

  // standard EMF code
  ResourceSet rs = new ResourceSet();
  Resource resource = rs.getResource(URI.create("path/to/MyFile.mydsl", true)
  ...
}

I tried to use your code but which I can write is like this Confused

		new CarStandaloneSetup().createInjectorAndDoEMFRegistration();
		ResourceSet rs = new ResourceSet() {

			public void eSetDeliver(boolean deliver) {
				// TODO Auto-generated method stub

			}

			public void eNotify(Notification notification) {
				// TODO Auto-generated method stub

			}

			public boolean eDeliver() {
				// TODO Auto-generated method stub
				return false;
			}

			public EList<Adapter> eAdapters() {
				// TODO Auto-generated method stub
				return null;
			}

			public void setURIConverter(URIConverter converter) {
				// TODO Auto-generated method stub

			}

			public void setResourceFactoryRegistry(
					org.eclipse.emf.ecore.resource.Resource.Factory.Registry resourceFactoryRegistry) {
				// TODO Auto-generated method stub

			}

			public void setPackageRegistry(Registry packageRegistry) {
				// TODO Auto-generated method stub

			}

			public URIConverter getURIConverter() {
				// TODO Auto-generated method stub
				return null;
			}

			public EList<Resource> getResources() {
				// TODO Auto-generated method stub
				return null;
			}

			public org.eclipse.emf.ecore.resource.Resource.Factory.Registry getResourceFactoryRegistry() {
				// TODO Auto-generated method stub
				return null;
			}

			public Resource getResource(URI uri, boolean loadOnDemand) {
				// TODO Auto-generated method stub
				return null;
			}

			public Registry getPackageRegistry() {
				// TODO Auto-generated method stub
				return null;
			}

			public Map<Object, Object> getLoadOptions() {
				// TODO Auto-generated method stub
				return null;
			}

			public EObject getEObject(URI uri, boolean loadOnDemand) {
				// TODO Auto-generated method stub
				return null;
			}

			public TreeIterator<Notifier> getAllContents() {
				// TODO Auto-generated method stub
				return null;
			}

			public EList<AdapterFactory> getAdapterFactories() {
				// TODO Auto-generated method stub
				return null;
			}

			public Resource createResource(URI uri, String contentType) {
				// TODO Auto-generated method stub
				return null;
			}

			public Resource createResource(URI uri) {
				// TODO Auto-generated method stub
				return null;
			}
		};

		Resource resource = rs.getResource(URI.createURI("D:\\...\\src\\car.car"), true);

Because ResourceSet is an interface. And imports are like this.

import java.util.Map;

import org.eclipse.emf.common.notify.Adapter;
import org.eclipse.emf.common.notify.AdapterFactory;
import org.eclipse.emf.common.notify.Notification;
import org.eclipse.emf.common.notify.Notifier;
import org.eclipse.emf.common.util.EList;
import org.eclipse.emf.common.util.TreeIterator;
import org.eclipse.emf.common.util.URI;
import org.eclipse.emf.ecore.EObject;
import org.eclipse.emf.ecore.EPackage.Registry;
import org.eclipse.emf.ecore.resource.Resource;
import org.eclipse.emf.ecore.resource.ResourceSet;
import org.eclipse.emf.ecore.resource.URIConverter;

Assign the injector you get from createInjectorAndDoEMFRegistration to a var and ask it for an instance of resourceset.
O r create a new resourcesetimpl

Please note this will only work in a standalone app

Now I'm using this code to load the model. Is it possible to save it in XMI format? Rolling Eyes

		Injector injector = new CarStandaloneSetup().createInjectorAndDoEMFRegistration();
		XtextResourceSet resourceSet = injector.getInstance(XtextResourceSet.class);
		resourceSet.addLoadOption(XtextResource.OPTION_RESOLVE_ALL, Boolean.TRUE);
		Resource resource = resourceSet.getResource(
			    URI.createURI("file:///D:/.../car.car"), true);
		AllCars model = (AllCars) resource.getContents().get(0);
