If this GoObject is part of a GoDocument this should possibly delay the call to CalculateRoute by calling GoDocument.GoDocument.UpdateRoute. Otherwise this should just call CalculateRoute to determine a new route immediately.

This is typically implemented as:

            public virtual void UpdateRoute() {
              GoDocument doc = this.Document;
              if (doc != null)
                doc.UpdateRoute(this);
              else
                CalculateRoute();
            }
