Member Function Documentation

virtual int32 CartoType::Router::TArc::Distance

(

double

aPointScale

)

const [pure virtual]

Return the distance along the arc in metres. This is not a straight-line distance but must follow any turns. aPointScale is the size of the units used for points, in metres.

CT_EXPORT double TArc::EndAngle

(

double

aMinDistance

)

const

Return the ending angle of an arc in radians, using a point at least aMinDistance along the arc if possible.

virtual void CartoType::Router::TArc::GetContour

(

TContour &

aContour

)

const [pure virtual]

Get a contour representing the arc, so that it can be drawn. The contour is returned in map coordinates.

virtual const CMapObject* CartoType::Router::TArc::MapObject

(

)

const [pure virtual]

Get the map object, if any, of which this arc is a part. If the arc is not part of a map object return NULL.

CT_EXPORT double TArc::StartAngle

(

double

aMinDistance

)

const

Return the starting angle of an arc in radians, using a point at least aMinDistance along the arc if possible.

Member Data Documentation

int32 CartoType::Router::TArc::iCost

CNode* CartoType::Router::TArc::iDest

The node at the end of the arc.
