vertices() [4/4]

vector< TransientVertex > MultiVertexReconstructor::vertices ( const std::vector< reco::TransientTrack > &  primaries, const std::vector< reco::TransientTrack > &  tracks, const reco::BeamSpot &  spot  ) const

overridevirtual

Reconstruct vertices, but exploit the fact that you know that some tracks cannot come from a secondary vertex. \paramname primaries Tracks that cannot come from a secondary vertex (but can, in principle, be non-primaries, also). \paramname tracks These are the tracks that are of unknown origin. These tracks are subjected to pattern recognition. \paramname spot A beamspot constraint is mandatory in this method.

Reimplemented from VertexReconstructor.
