Hi,

I am working with the commands and Handlers in eclipse.
I want to know how to create a classDiagram which contains an "InstanceSpecification" named for example "Task" and it has a classifier.

I'd appreciate any help on this.
Thanks in advance,

what do you mean?

These are the steps to create an instance specification:
* create a class diagram
* add a class with the tool from the palette
* add an instance specification with the tool from the palette
* select the instance spec. and go to the properties view
* in uml tab, go to the classifier section, click the "+" sign and add the class you just created

Hi,

Thanks for your reply.

I'm doing a project using the Plug-in papyrus Marte in eclipse, I add a popup menu
named "named import platform" using commands and Handlers in the view
of the Model Explorer when creating a papyrus Model.
My goal is when I click on the command which defined by the popup menu, a ClassDiagram will be created and it contains the "Instance Specification" which I have implemented.
I used this method

protected Diagram createDiagram(Resource diagramResource, EObject owner, String name) {

  Diagram diagram=null;
			
  if(owner instanceof org.eclipse.uml2.uml.Package) {

	Package pkg=(Package) ((Package) (owner)).getPackagedElement("UMLPackage.eINSTANCE.getPackage());
					
	Class sharedResource = (Class((Package)owner).createOwnedClass("sharedResource", false);
			Property attribute = sharedResource.createOwnedAttribute(
	                "newAttribute", null, UMLPackage.Literals.PROPERTY);
			
				diagram = ViewService.createDiagram(owner, getDiagramNotationID(), getPreferenceHint());

	
				diagram.setName(name);

				//diagram.setElement();

				diagramResource.getContents().add(diagram);
			}
		
			return diagram;	
		}

		@Override

	protected String getDiagramNotationID() {

		return ModelEditPart.MODEL_ID;

	}

	@Override

	protected PreferencesHint getPreferenceHint() {

		return UMLDiagramEditorPlugin.DIAGRAM_PREFERENCES_HINT;

	}

	@Override

	protected String getDefaultDiagramName() {

		return super.openDiagramNameDialog("specific model diagram"); 

	}

	@Override
	public Object execute(ExecutionEvent event) throws ExecutionException {
		return super.execute(event);
	}

}

But this method will create a class Diagram which contains Class not Instance Specification.

Can you help me please.

can you concretize your problem? do you mean in the newly created class diagram there is no palette tool for instance specifications? or do you want to create instance specifications (and graphical representations for them) automatically when the new diagram is created?

Hi,

Yes, I want to create instance specifications (and graphical representations for them)in the view of the new Class Diagram automatically when the new diagram is created.

try this in your handler (I have not tested it):

		ServicesRegistry serviceRegistry = ServiceUtilsForActionHandlers
				.getInstance().getServiceRegistry();
TransactionalEditingDomain ed = ServiceUtils.getInstance().getTransactionalEditingDomain(serviceRegistry);
			
			RecordingCommand c = new RecordingCommand(ed) {
				
				@Override
				protected void doExecute() {
					
					Model model =// get a reference of the root element of the uml model
					
					InstanceSpecification spec = UMLFactory.eINSTANCE.createInstanceSpecification();
					org.eclipse.uml2.uml.Class type = UMLFactory.eINSTANCE.createClass();
					spec.getClassifiers().add(type);
					model.getPackagedElements().add(type);
					model.getPackagedElements().add(spec);
					
					
				}
			};
			
			ed.getCommandStack().execute(c);

In general, this only creates the model element. But if you're lucky the graphical representations in the diagram are also created for free.
