)

The LinkEdit that was added to the database.
Remarks

When applied, speeds will be converted into miles per hour and rounded down to the largest integer value that is no larger than the specified speed. A negative speed can be applied, and indicates that the original speed from strategy's RoutingProfile will be used. The maximum speed that can be specified is 254mph.

If the returned LinkEdit object is changed, the change will only be applied to the database if UpdateLinkEdit is called.

        new Telogis.GeoBase.Routing.LinkEdit.LinkEditDatabase();
    // Then create a link selection. This example specifies a single link.

        new Telogis.GeoBase.Routing.LinkEdit.LatLonSelection(new LatLon(33.632024, -117.815720));
