GraphitiInternal.getEmfService() [message #958824]

I want to get the DiagramTypeProvider for a diagram. After some searching I found that the EmfService has a method called getDTPForDiagram(Diagram), exactly what I need.
However, to access this EmfService I have to go to the class GraphitiInternal. Of course I get a "discouraged access" warning. Is there a reason for making this class internal?

Jos

Watch out: EmfService implements the IEmfService interface, but there are two IEmfService interfaces. One in the internal package, and one in the visible ui package.

Jos,

if you have access to the feature provider you can get the
DiagramTypeProvider from it, also the DiagramEditor offers a method to get
it. Does that help in you scenario?

There are 2 EMFServices in Graphiti, of which only one is for external
usages. This is done on purpose, as the methods in the internal one should
be used only in very defined situations.

Michael,

It might help if I can get the feature provider based on the diagram. I did not find such a service yet. Is there a way to achieve this?

Jos,

hm, not directly getting, but creating is possible:
org.eclipse.graphiti.ui.services.GraphitiUI.getExtensionManager().createFeatureProvider(Diagram
diagram);
