Hi,

Is there a straightforward way to print out the xmi id of an object from an Xpand template?

In particular, I'm trying to get at the xmi id of an item with a custom uml profile stereotype.

Any advice would be greatly appreciated.

Hi,

Since XMI is just one way of Persisting stuff reading the XMI Id is not a default usecase.

why do you need the xmi ids?

but this java extension should do the stuff.

package template;
import org.eclipse.emf.ecore.EObject;
import org.eclipse.emf.ecore.resource.Resource;
import org.eclipse.emf.ecore.xmi.XMLResource;

public class Extensions {
	
	public static String xmiId(EObject x) {
		Resource resouce = x.eResource();
		if (resouce instanceof XMLResource) {
			XMLResource xmlResource = (XMLResource)resouce;
			return xmlResource.getID(x);
		}
		return "";
	}

}

template/GeneratorExtensions.ext

String xmiID(emf::EObject x) :
	JAVA template.Extensions.xmiId(org.eclipse.emf.ecore.EObject);

template.xpt

«EXTENSION template::GeneratorExtensions»
....
«DEFINE main FOR test::Bean»
....
//«this.xmiID()»
....

Hi Christian,

Some of the downstream tools that will be utilizing the xpand output for this particular usage scenario needed the xmi id. I tried out your recommended approach, and it works as expected.

Thanks again for your quick responses. It is most appreciated!!

Cheers,

Lourdes
