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.

vertex() [2/7]

template<unsigned int N>

virtual CachingVertex<N> VertexFitter< N >::vertex ( const std::vector< typename CachingVertex< N >::RefCountedVertexTrack > &  tracks ) const

pure virtual

Fit vertex out of a set of VertexTracks. For the first iteration, the already linearized track will be used.

template<unsigned int N>

virtual CachingVertex<N> VertexFitter< N >::vertex ( const std::vector< typename CachingVertex< N >::RefCountedVertexTrack > &  tracks, const reco::BeamSpot &  spot  ) const

pure virtual

Same as above, only now also the BeamSpot constraint is provided.

vertex() [4/7]

template<unsigned int N>

virtual CachingVertex<N> VertexFitter< N >::vertex ( const std::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 SequentialVertexFitter< N >, SequentialVertexFitter< 5 >, AdaptiveVertexFitter, KalmanVertexFitter, GsfVertexFitter, AdaptiveGsfVertexFitter, AbstractConfFitter, ConfigurableVertexFitter, and TrimmedVertexFitter.

template<unsigned int N>

virtual CachingVertex<N> VertexFitter< N >::vertex ( const std::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 SequentialVertexFitter< N >, SequentialVertexFitter< 5 >, AdaptiveVertexFitter, KalmanVertexFitter, AdaptiveGsfVertexFitter, GsfVertexFitter, AbstractConfFitter, ConfigurableVertexFitter, and TrimmedVertexFitter.

vertex() [6/7]

template<unsigned int N>

virtual CachingVertex<N> VertexFitter< N >::vertex ( const std::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 SequentialVertexFitter< N >, SequentialVertexFitter< 5 >, AdaptiveVertexFitter, KalmanVertexFitter, GsfVertexFitter, AdaptiveGsfVertexFitter, TrimmedVertexFitter, AbstractConfFitter, and ConfigurableVertexFitter.

template<unsigned int N>

virtual CachingVertex<N> VertexFitter< N >::vertex ( const std::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.
