Containment relationship between DiagramObject and DiagramLink

[priombiswas89]

I am trying to get the containment relationship between a fragment(DiagramObject) and connector(DiagramLink). Below is the sequence diagram:

I am trying the below code to get the coordinates of DiagramObject and DiagramLink:

Code: [Select]

foreach (EA.DiagramLink link in diag.DiagramLinks)
            {
                EA.Connector connector = rep.GetConnectorByID(link.ConnectorID);
                startX = connector.StartPointX;
                startY = connector.StartPointY;
                endX = connector.EndPointX;
                endY = connector.EndPointY;
            }
            foreach (DiagramObject diagramObj in diag.DiagramObjects)
            {
                int elementId = diagramObj.ElementID;
                EA.Element element = rep.GetElementByID(elementId);
               
                if (element.MetaType.Equals("InteractionFragment"))
                {
                    top = diagramObj.top;
                    bottom = diagramObj.bottom;
                    left = diagramObj.left;
                    right = diagramObj.right;
                    GetTypeName(element);
                }
            }

I am not sure how to compare startX, startY, endX, endY (DiagramLink) to top, bottom, left and right (DiagramObject) to check whether the diagramlinks are contained inside the diagramobject. Any kind of help will be much appreciated.
