Execute is a method to compute the driving directions. This method takes a set containing the route features that you want to generate directions for. If null is passed in, it will generate directions for all routes. If you want to generate directions for a subset of the routes, create a new set object and add route features from the corresponding Routes or CFRoutes network analysis class.
