Hi Xiao

Try these methods getFeatureProvider().getBusinessObjectForPictogramElement(getDiagram());
getFeatureProvider().getAllBusinessObjectsForPictogramElement(getDiagram())

Hope this helps.

Thanks

Hi,PALANI SANKAR
Thank you for your advice for these methods ,but these methods did not give me a help.I can only get an empty array. I do not know why. I also tried getPictogramLinks() method on diagram,this method can help me to get all links and then get all business objs,but by this I get more than what I need. I know get the objs by filtering, but I think there should be a method provided by Graphiti to get domain model objs in an elegant way.

This code gives you the business object(s) directly related to the
diagram itself, which is a PictogramElement. Sometimes this is the root
object of your model, but not always. You must use a PictogramElement
further down the Shape containment hierarchy.

Besides showing the objects' state at a particular point in time, an object diagram can also be used to represent the occurrences of interactions between classes in runtime. The result looks a bit like a communication diagram. The figure below provides an example of such a class diagram and its corresponding object diagram:
