For consistency, define these three static methods in FGPositioned.
FGPositioned::isAirportType() is the same as FGAirport::isAirportType()
(piece of code moved from airport.cxx to positioned.cxx, and
FGAirport::isAirportType() now calls FGPositioned::isAirportType()).
- FGPositioned::isAirportType() returns true for AIRPORT, HELIPORT,
SEAPORT;
- FGPositioned::isRunwayType() returns true for RUNWAY;
- FGPositioned::isNavaidType() returns true for NDB, VOR, ILS, LOC, GS,
DME, TACAN.
- change launcher to examine the scenery paths and hence load
ground-net files for airports to populate parking data.
- refactor ground-net XML parsing to use FGGroundNetwork only, not
AirportDynamics.
- change parenting of GroundNetwork to Airport, since it contains
immutable data now.
Ensure all FGPositioned related functions return SGSharedPtr
instead of raw pointers to allow automatic conversion to
nasal ghosts without custom helper functions.
For now it is available in the positioned Nasal
module. FGAirport is fully ported, but especially
procedures/navaids and free functions are still
missing.
This was a bogus concept, either runways have a reciprocal or not (if singled-ended), really this was simply exposing an artefact of the apt.dat encoding. Change to an API which gives what is actually wanted - the ability to extract an airport's runways without any reciprocals included.
