Member Function Documentation

Create()

std::unique_ptr< TileIterator > TileIterator::Create ( TileIndex corner1, TileIndex corner2, bool diagonal )

static

Create either an OrthogonalTileIterator or DiagonalTileIterator given the diagonal parameter.

Parameters

corner1	Tile from where to begin iterating.
corner2	Tile where to end the iterating.
diagonal	Whether to create a DiagonalTileIterator or OrthogonalTileIterator.

Returns

unique_ptr to the allocated TileIterator.

operator TileIndex()

TileIterator::operator TileIndex ( ) const

inline

Get the tile we are currently at.

Returns

The tile we are at, or INVALID_TILE when we're done.

Definition at line 142 of file tilearea_type.h.

operator*()

TileIndex TileIterator::operator* ( ) const

inline

Get the tile we are currently at.

Returns

The tile we are at, or INVALID_TILE when we're done.

Definition at line 151 of file tilearea_type.h.

operator++()

virtual TileIterator & TileIterator::operator++ ( )

pure virtual

Move ourselves to the next tile in the rectangle on the map.

Returns

Reference to this iterator.

Implemented in AirportTileIterator, AirportTileTableIterator, BitmapTileIterator, DiagonalTileIterator, and OrthogonalTileIterator.

References TileIterator().

operator==() [1/2]

bool TileIterator::operator== ( const TileIndex & rhs ) const

inline

Equality comparison.

Parameters

rhs	The other iterator to compare to.

Returns

true iff the tile of both iterators is the same.

Definition at line 177 of file tilearea_type.h.

operator==() [2/2]

bool TileIterator::operator== ( const TileIterator & rhs ) const

inline

Equality comparison.

Parameters

rhs	The other iterator to compare to.

Returns

true iff the tile of both iterators is the same.

Definition at line 167 of file tilearea_type.h.
