Creating diagram using UML2 tools APIs [message #476297] |

Hi All;
I am creating a UML file into Eclipse workspace and want to create/open
diagram as well for this file using UML2 Tools APIs as :
String uriFile = file.getFullPath().toString();
URI resourceURI = URI.createPlatformResourceURI(uriFile, false);
URI diagramURI = URI.createPlatformResourceURI(uriFile + "act", false);
Resource diagram = UMLDiagramEditorUtil.createDiagram(diagramURI,
resourceURI, new NullProgressMonitor());
UMLDiagramEditorUtil.openDiagram(diagram);
but above piece of code creates a diagram file into workspace but it does
not contains any contents and the resource uml file becomes empty.
And generates the "Null Pointer Exception" error.
Please tell me, what is wrong in my code or tell me the right way to
create a diagram (activity, Class, use case) by giving a uml file path.
Thanks in Advance.
Kishore
Regards,
Kishore

Hello Kishore,
UMLDiagramEditorUtil.createDiagram(URI diagramURI, URI modelURI, IProgressMonitor
progressMonitor) method creates a _new_ model, and a new diagram:
....Package model = createInitialModel();
....
So, if you want to create a new diagram for an _existing_ model you have
to copy the code from the method and assign 'model' variable with content
of the existing modelFile:
Package model = getModelRoot(modelURI);
getModelRoot() method can look like this:
private EObject getModelRoot(URI domainModelURI , ResourceSet resourceSet) {
myModelResource = resourceSet.getResource(domainModelURI, true);
EObject modelRoot = (EObject) myModelResource.getContents().get(0);
return modelRoot;
}
Best wishes,
Tanya.
