get SuperTypes of EClasses??? [message #394950]

Hi,

I want to read the SuperTypes of an EClass in an EcoreXML-File.
The problem is not to read it. The problem is, that I get all SuperTypes
(SuperTypes of the SuperTypes of the SuperTypes) too.

For example when I want to read the Ecore.ecore:
When I say:
for (Iterator i = eclass.getESuperTypes().iterator(); i.hasNext();){
supertypeclass = (EClass) i.next();
System.out.println(supertypeclass.getName());
}
// in this case "eclass.getName()" is "EAttribute"

The result of the System.out.println is:
EAnnotation
EClass
EClassifier
EDataType
EEnum
EEnumLiteral
EFactory
EModelElement
ENamedElement
EObject
EOperation
EPackage
EParameter
EReference
EStructuralFeature
ETypedElement
EStringToStrongMapEntry.

OK I know that is right, but I only want to read the "direct SuperTypes"
which you can see in the Editor and which is the only mentioned
SuperType(s) in the Ecore.ecore (in the case of EAttribute it is
EStructuralFeature).

Does anyone know how to filter the rest of the SuperTypes?

Thanks in advance,
Karl

Hi Karl,

I've created the following class in a Java project that has
org.eclipse.emf.ecore as one of its dependencies. It printed out
exactly what you are looking for (ie, "EStructurealFeature").

public class Test
{
public static void main(String[] args)
{
EClass eclass = EcorePackage.eINSTANCE.getEAttribute();
for (Iterator i = eclass.getESuperTypes().iterator(); i.hasNext();)
{
EClass supertypeclass = (EClass)i.next();
System.out.println(supertypeclass.getName());
}
}
}

Maybe you could post here a small test reproducing the problem you are
seeing.

Cheers,
Marcelo

Hi, maybe my description was unclear

I read the EClassifier EAttribute from the File "Ecore.ecore" from the
filesystem. It can be found in the plugin-directory of Eclipse in the
Folder:
org.eclipse.emf.source_2.0.3\src\org.eclipse.emf.ecore_2.0.3 \runtime\ecoresrc.zip

I loaded the EcoreFile stand alone(created a resource set, registered it
to a resource factory, etc) like in:
http://eclipse.org/emf/docs.php?doc=references/overview/EMF. html
section: "Saving and loading resources"

I hope it becomes more understandable?

Regards,
Karl

Hi,

You were perfectly clear before ;-) My point is that since everything
is OK when I work with a direct reference of the EAttribute eclass, the
problem is somehow related to the way you are loading the resource.
Better than trying to guess what you are doing, it would be good if you
could provide a simple example.

Cheers,
Marcelo.

Hi Marcelo,

...I'm so mortified.
The problem is solved. I wrote 2 loops. The first iterates the classifiers
and the second iterates the SuperTypes of this classifiers. In the second
loop I iterated the first one.

Thanks for your help!

Regards, Karl
