const AirportFTAClass* Airport::GetFTA (  )  const [inline]

Get the finite-state machine for this airport or the finite-state machine for the dummy airport in case this isn't an airport.

Precondition:
this->type < NEW_AIRPORT_OFFSET.
Returns:
The state machine for this airport.

const HangarTileTable* Airport::GetHangarDataByTile ( TileIndex  tile  )  const [inline, private]

Retrieve hangar information of a hangar at a given tile.

Parameters:
tile Tile containing the hangar.
Returns:
The requested hangar information.
Precondition:
The tile must be at a hangar tile at an airport.

Definition at line 399 of file station_base.h.

Direction Airport::GetHangarExitDirection ( TileIndex  tile  )  const [inline]

Get the exit direction of the hangar at a specific tile.

Parameters:
tile The tile to query.
Precondition:
IsHangarTile(tile).
Returns:
The exit direction of the hangar, taking airport rotation into account.

uint Airport::GetHangarNum ( TileIndex  tile  )  const [inline]

Get the hangar number of the hangar at a specific tile.

Parameters:
tile The tile to query.
Precondition:
IsHangarTile(tile).
Returns:
The hangar number of the hangar at the given tile.

TileIndex Airport::GetHangarTile ( uint  hangar_num  )  const [inline]

Get the first tile of the given hangar.

Parameters:
hangar_num The hangar to get the location of.
Precondition:
hangar_num < GetNumHangars().
Returns:
A tile with the given hangar.

TileIndex Airport::GetRotatedTileFromOffset ( TileIndexDiffC  tidc  )  const [inline]

Add the tileoffset to the base tile of this airport but rotate it first.

The base tile is the northernmost tile of this airport. This function helps to make sure that getting the tile of a hangar works even for rotated airport layouts without requiring a rotated array of hangar tiles.

Parameters:
tidc The tilediff to add to the airport tile.
Returns:
The tile of this airport plus the rotated offset.

const AirportSpec* Airport::GetSpec (  )  const [inline]

Get the AirportSpec that from the airport type of this airport.

If there is no airport (tile == INVALID_TILE) then return the dummy AirportSpec.

Returns:
The AirportSpec for this airport.
