		const SiPixelRecHit *	rh,
		const PixelClusterParameterEstimator *	cpe,
		bool	computeCoarseLocalPosition
	)		`[private]`

This private constructor copies the TrackingRecHit. It should be used when the TrackingRecHit exist already in some collection.

virtual bool TSiPixelRecHit::canImproveWithTrack ( ) const [inline, virtual]

Returns true if the clone( const TrajectoryStateOnSurface&) method returns an improved hit, false if it returns an identical copy. In order to avoid redundent copies one should call canImproveWithTrack() before calling clone( const TrajectoryStateOnSurface&).

TSiPixelRecHit::RecHitPointer TSiPixelRecHit::clone ( const TrajectoryStateOnSurface & ts ) const [virtual]

Returns a copy of the hit with parameters and errors computed with respect to the TrajectoryStateOnSurface given as argument. For concrete hits not capable to improve their parameters and errors this method returns an exact copy, and is equivalent to clone() without arguments.
