Detailed Description

template<unsigned int N>
class VertexFitter< N >

Pure abstract base class for VertexFitters.

Fits a CachingVertex using either:

• TransientTracks;
• VertexTracks. A linearization point can be specified, or a prior estimate of the vertex position and error.

Member Function Documentation

template<unsigned int N>

virtual VertexFitter* VertexFitter< N >::clone

(

)

const [pure virtual]

Fit vertex out of a VertexSeed.

Implemented in AdaptiveVertexFitter, AbstractConfFitter, ConfigurableAdaptiveFitter, ConfigurableKalmanFitter, ConfigurableVertexFitter, AdaptiveGsfVertexFitter, GsfVertexFitter, KalmanVertexFitter, TrimmedVertexFitter, SequentialVertexFitter< N >, and SequentialVertexFitter< 5 >.

template<unsigned int N>

virtual CachingVertex<N> VertexFitter< N >::vertex	(	const vector< typename CachingVertex< N >::RefCountedVertexTrack > &	tracks,
		const GlobalPoint &	priorPos,
		const GlobalError &	priorError
	)			const [pure virtual]

Fit vertex out of a set of VertexTracks.

Uses the specified point and error as the prior estimate of the vertex. This position is NOT used to relinearize the tracks.

template<unsigned int N>

virtual CachingVertex<N> VertexFitter< N >::vertex	(	const vector< reco::TransientTrack > &	tracks,
		const reco::BeamSpot &	beamSpot
	)			const [pure virtual]

Fit vertex out of a set of TransientTracks.

The specified BeamSpot will be used as priot, but NOT for the linearization. The specified LinearizationPointFinder will be used to find the linearization point.

Implemented in AdaptiveVertexFitter, AbstractConfFitter, ConfigurableVertexFitter, AdaptiveGsfVertexFitter, GsfVertexFitter, KalmanVertexFitter, TrimmedVertexFitter, SequentialVertexFitter< N >, and SequentialVertexFitter< 5 >.

template<unsigned int N>

virtual CachingVertex<N> VertexFitter< N >::vertex	(	const vector< reco::TransientTrack > &	tracks,
		const GlobalPoint &	priorPos,
		const GlobalError &	priorError
	)			const [pure virtual]

Fit vertex out of a set of TransientTracks.

Uses the specified point as both the linearization point AND as prior estimate of the vertex position. The error is used for the weight of the prior estimate.

Implemented in AdaptiveVertexFitter, AbstractConfFitter, ConfigurableVertexFitter, and TrimmedVertexFitter.

template<unsigned int N>

virtual CachingVertex<N> VertexFitter< N >::vertex	(	const vector< reco::TransientTrack > &	tracks,
		const GlobalPoint &	linPoint
	)			const [pure virtual]

Fit vertex out of a set of TransientTracks.

The specified point will be used as linearization point, but will NOT be used as prior.

Implemented in AdaptiveVertexFitter, AbstractConfFitter, ConfigurableVertexFitter, and TrimmedVertexFitter.
