Hi all,

I want to modify an UML Class Diagram by java code, for this purpose first, I load an UML model by below java code, But I don't know how to change elements of "UMLModel" in run method. (for example change name of "Person" class to "Human").

package example ; 

import java.io.File;
import java.util.ArrayList;
import java.util.Collection;

import org.eclipse.emf.common.util.URI;
import org.eclipse.emf.ecore.EPackage;
import org.eclipse.emf.ecore.resource.Resource;
import org.eclipse.emf.ecore.resource.ResourceSet;
import org.eclipse.emf.ecore.resource.impl.ResourceSetImpl;
import org.eclipse.epsilon.emc.emf.InMemoryEmfModel;
import org.eclipse.uml2.uml.UMLPackage;
import org.eclipse.uml2.uml.resource.UMLResource;
import org.eclipse.uml2.uml.resources.util.UMLResourcesUtil;

public class MinimalExample {
	
	public static void main(String[] args) throws Exception {
		new MinimalExample().run();
	}
	
	public void run() throws Exception {
		InMemoryEmfModel Model = getUmlModel("UMLModel", new File("src/models/Dev1.uml"));
		
	}
	
	public InMemoryEmfModel getUmlModel(String name, File file) throws Exception {
		ResourceSet set = new ResourceSetImpl();
		UMLResourcesUtil.init(set);
		set.getPackageRegistry().put(UMLPackage.eNS_URI, UMLPackage.eINSTANCE);
		set.getResourceFactoryRegistry().getExtensionToFactoryMap().
		         put(UMLResource.FILE_EXTENSION, UMLResource.Factory.INSTANCE);
		Resource r = set.getResource(URI.createFileURI(file.getAbsolutePath()), true);
		r.load(null);
		
		Collection<EPackage> ePackages = new ArrayList<EPackage>();
		for (Object ePackage : set.getPackageRegistry().values()) {
			ePackages.add((EPackage) ePackage);
		}
		return new InMemoryEmfModel(name, r, ePackages);
	}
}

Can one help me?

I used emc and eol epsilon plugin for this project and attached a minimal example to this post.

Best regards,
Mohammadreza

Hi,

Mohammadreza,

I don't know what emc and eol are.

But the UML2 project provides an API that has all of the tools
necessary for manipulation of UML models, including modification of all
of the attributes and associations defined by the language
specification. For example, to change the name of a class from
"Person" to "Human", you would simply use the
org.eclipse.uml2.uml.NamedElement::setName method, as the Java class
implementing the UML Class metaclass conforms to the NamedElement Java
interface.

HTH,

Christian

Hi

It's best to ask Epsilon questions on the Epsilon newsgroup.
