Detailed Description

ITruthToTrack is an interface to create Trk::TrackParameters from a HepMC::GenParticle.

The motivation is to use a Trk::IExtrapolator for extrapolation of "true" track parameters.

makePerigeeParameters() [1/2]

virtual const Trk::TrackParameters* Trk::ITruthToTrack::makePerigeeParameters ( const xAOD::TruthParticle *  part ) const

pure virtual

Implemented in Trk::TruthTrackRecordToTrack, and Trk::TruthToTrack.

makePerigeeParameters() [2/2]

virtual const Trk::TrackParameters* Trk::ITruthToTrack::makePerigeeParameters ( HepMC::ConstGenParticlePtr  part ) const

pure virtual

This function extrapolates track to the perigee, and returns perigee parameters.

The return value points to an object allocated with the operator new. The caller is responsible for deletion of the object.

Implemented in Trk::TruthTrackRecordToTrack, and Trk::TruthToTrack.

makeProdVertexParameters() [1/2]

virtual const Trk::TrackParameters* Trk::ITruthToTrack::makeProdVertexParameters ( const xAOD::TruthParticle *  part ) const

pure virtual

Implemented in Trk::TruthTrackRecordToTrack, and Trk::TruthToTrack.

makeProdVertexParameters() [2/2]

virtual const Trk::TrackParameters* Trk::ITruthToTrack::makeProdVertexParameters ( HepMC::ConstGenParticlePtr  part ) const

pure virtual

This function produces a Trk::TrackParameters object corresponding to the HepMC::GenParticle at the production vertex.

The object is allocated using operator new and returned by pointer. The caller is responsible for deletion of the object. (Wrapping it into a smart pointer may be the most convenient way to make sure the memory is freed.)

Implemented in Trk::TruthTrackRecordToTrack, and Trk::TruthToTrack.
