Ecore tools 2.0.3 Issue with generic ETypeParameter [message #1488854] Thu, 27 November 2014 00:11

In the traditional ecore model editor, one can define a class MyClass<T extends SomeClass> by specifying a bounding classifier (SomeClass) for the type parameter.

Creating a representation file for an existing .ecore model with such use of generics seem to perfectly understand this construct. By selecting the type parameter of the class, and selecting the Semantic section of the properties one reads "T extends SomeClass" on the first line and "T" for the name of the parameter.

However, I could not find a way to reproduce this construct using the latest (2.0.3) ecore diagram editor.

The overview documentation shows a more complex example using generics with a <<bind>> constraint. However, I found no reference on how Constraints and Constraint Assignments could be used in this case, that is for setting the bound "extends SomeClass" on a class type parameter.

Thanks for your support.

Yes Actually I need bidirectional E-References, but the issue is not about including machine m1 and included one m2. it about two machine which share some property and they are exactly equal in roles, there is no difference between m1 and m2 and they both should have the same role for each other (which is shares property).

the issue is that I observed before, while exploring previous topics,that bidirectional E-References are not allowed in the E-core model (E-Opposite property). So I'm trying to handle this using java model code for both single values and multiple values E-references.

Hi Sebastian

I am still not able to get the "Sample Reflective Ecore model Editor " to work. Although I got my own piece of code to work and produce the EMF model editor. But now I want to open my xtext model with the option "Sample Reflective Ecore model Editor ", so that I can make changes through the generated editor. I also want to know how to create extension parser registration for my file extension, as you suggested above. I am quite new at this. Sad Please help. I am getting the following error.

org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: org.xml.sax.SAXParseExceptionpublicId: platform:/resource/mnc.test/src/gmrt.mncspec; systemId: platform:/resource/mnc.test/src/gmrt.mncspec; lineNumber: 1; columnNumber: 1; Content is not allowed in prolog.

Ok , you can see the following code.
First, I can get a EClass dynamically
public static EClass getEClass() {
		 * Instantiate EcoreFactory
		final EcoreFactory theCoreFactory = EcoreFactory.eINSTANCE;

		 * Create EClass instance to model BookStore class
		final EClass bookStoreEClass = theCoreFactory.createEClass();

		 * Create EClass instance to model Book class
		final EClass bookEClass = theCoreFactory.createEClass();

		 * Instantiate EPackage and provide unique URI
		 * to identify this package
		final EPackage bookStoreEPackage = theCoreFactory.createEPackage();
		 * Instantiate EcorePackage
		final EcorePackage theCorePackage = EcorePackage.eINSTANCE;

		 * Create attributes for BookStore class as specified in the model
		final EAttribute bookStoreOwner = theCoreFactory.createEAttribute();
		final EAttribute bookStoreLocation = theCoreFactory.createEAttribute();
		final EReference bookStore_Books = theCoreFactory.createEReference();
		 * Create attributes for Book class as defined in the model
		final EAttribute bookName = theCoreFactory.createEAttribute();
		final EAttribute bookISBN = theCoreFactory.createEAttribute();
		 * final Add owner, location and final books attributes/references
		 * to BookStore class

		 * Add name and isbn attributes to Book class

		 * Place BookStore and Book classes in bookStoreEPackage
		return bookStoreEClass;


Then I use the returned EClass to get a UI component by EMF Forms.
EObject dummObject = EcoreUtil.create(bookStoreEClass);
			final ViewModelContext vmc = ViewModelContextFactory.INSTANCE.createViewModelContext(
				ViewProviderHelper.getView(dummyObject, null), dummyObject, new DefaultReferenceService());

			render = ECPSWTViewRenderer.INSTANCE.render(content, vmc);

The generated UI component should contain three kind of controls for three feature of bookstore, but it only contains two (owner and location, but not books), you can see screenshot (result.png), but the expected result should be like expected.png.
