Detailed Description
An abstract base class to provide information needed by the routing system. Although nodes are writable, all nodes returned by the CRouterInfo object are owned and managed by that object and are destroyed when the object is destroyed.
Member Function Documentation
| virtual int32 CartoType::Router::CRouterInfo::HeuristicWeight | ( | ) | [pure virtual] |
Return the weight by which distances are multiplied to get the lowest possible cost of traversing a distance. This must be the weight for the fastest road type in the data. It is called the 'heuristic weight' because the term 'heuristic' is used for the estimated cost in discussions of the A-star algorithm.
Implemented in CartoType::Router::CMapDataRouterInfo.
| virtual CNode* CartoType::Router::CRouterInfo::Node | ( | TResult & | aError, |
| const TPoint & | aPoint | ||
| ) | [pure virtual] |
Return a pointer to the nearest node to aPoint.
Implemented in CartoType::Router::CMapDataRouterInfo.
| virtual TPointFormat CartoType::Router::CRouterInfo::PointFormat | ( | ) | [pure virtual] |
Return the format of the map data points.
Implemented in CartoType::Router::CMapDataRouterInfo.
