Hi,

I want to use the identity of a specific diagram as an input parameter to a service function.
Specifically, I want to implement a function find(EObject, Diagram) that is defined on a semantic object and finds its representational element in the specific diagram.

Any advice?

Regards,
Avi

I have succeeded doing this by doing the following:

public void encapsulateElements(Process process, DDiagram diagram) {
Collection<EObject> result = new EObjectQuery(process).getInverseReferences(ViewpointPackage.Literals.DSEMANTIC_DECORATOR__TARGET);
result.removeIf(n->!(((DDiagramElement) n).getParentDiagram().equals(diagram)));

I would love to know if there's an easier way.

Hi,

Depending on where your service is called, you might have access to the view variable (elementView, containerView etc) in your odesign. This view variable references a DDiagramElement.

Regards,

Florian
