Member Function Documentation

virtual Surface* trkf::Surface::clone ( ) const

pure virtual

Clone method.

Implemented in trkf::SurfXYZPlane, trkf::SurfYZLine, and trkf::SurfYZPlane.

virtual double trkf::Surface::distanceTo ( const Surface & surf ) const

pure virtual

Find perpendicular forward distance to a parallel surface.

Implemented in trkf::SurfXYZPlane, trkf::SurfYZLine, and trkf::SurfYZPlane.

Referenced by getDirection().

TrackVector trkf::Surface::getDiff	(	const TrackVector &	vec1,
		const TrackVector &	vec2
	)		const

virtual

Calculate difference of two track parameter vectors.

Calculate difference of two track parameter vectors. This method has a default implementation which is just the numeric difference. Surfaces that require a more sophisticated difference (e.g. phi-wrap difference) should override this method.

Reimplemented in trkf::SurfYZLine.
