Detailed Description

The RoadSource interface example.

An abstract interface to 3D road information given by an STL vector of 3D points

Constructor & Destructor Documentation

virtual RoadSource::~RoadSource (   )  [inline, virtual]

Empty virtual destructor for RoadSource. For C++ syntax reasons, it is a good idea to explicitly define a virtual destructor, even if empty like this one, to any abstract class like this. Definition at line 32 of file RoadSource.h.

Member Function Documentation

virtual bool RoadSource::getPoints (  utils::Time &  time, std::vector< utils::Vec3d > &  points, bool  blocking = 1 )  [pure virtual]

Get the next set of road points. Returns the latest set of road points along with the time at which they were collected. Normally, the call is blocking, i.e., we block until the next unread set of points is acquired, but it can be polling, i.e., it returns immediately with the most recent set of road points. Parameters: [out]  time  The time at which the road information was collected. (0 if the road is invalid) [out]  points  The vector of 3D road points [in]  blocking  If true, then the call is blocking, if false, it is polling. Returns: true if "new" data has been acquired successfully, false on an invalid read or if no new road data has been acquired since the last read. Note an invalid read can be verified by checking to see if time.isZero() is true. Implemented in FakeRoadSource, OutputRoadSource, PlayerRoadSource, and ShmemRoadSource. Referenced by OutputRoadSource::getPoints().
