CacheBeamSpotData()

virtual const InDet::BeamSpotData * Trk::ITrackParticleCreatorTool::CacheBeamSpotData ( const EventContext & ctx ) const

pure virtual

Convenience method to retrieve Beamspot Data object.

createParticle() [1/4]

virtual xAOD::TrackParticle * Trk::ITrackParticleCreatorTool::createParticle ( const EventContext & ctx, const ElementLink< TrackCollection > & trackLink, xAOD::TrackParticleContainer * container = nullptr, const xAOD::Vertex * vxCandidate = nullptr, xAOD::ParticleHypothesis prtOrigin = xAOD::noHypothesis ) const

pure virtual

Method to construct a TrackParticle from a passed Track.

Parameters

track	element link to a valid track (i.e. do not pass a zero!).
TrackParticleContainer	needed to have an AuxStore, if provided particle will be added to store which takes ownership
xAOD::Vertex	Pointer to a vxCandidate.
prtOrigin

createParticle() [2/4]

virtual xAOD::TrackParticle * Trk::ITrackParticleCreatorTool::createParticle ( const EventContext & ctx, const Perigee * perigee, const FitQuality * fq, const TrackInfo * trackInfo, const TrackSummary * summary, const std::vector< const Trk::TrackParameters * > & parameters, const std::vector< xAOD::ParameterPosition > & positions, xAOD::ParticleHypothesis prtOrigin = xAOD::noHypothesis, xAOD::TrackParticleContainer * container = nullptr ) const

pure virtual

create a xAOD::TrackParticle out of constituents (please don't use this

• it will eventually be removed)

createParticle() [3/4]

virtual xAOD::TrackParticle * Trk::ITrackParticleCreatorTool::createParticle ( const EventContext & ctx, const Rec::TrackParticle & trackParticle, xAOD::TrackParticleContainer * container = nullptr ) const

pure virtual

Method to construct a xAOD::TrackParticle from a Rec::TrackParticle.

Parameters

track	particle
TrackParticleContainer	needed to have an AuxStore, if provided particle will be added to store which takes ownership

createParticle() [4/4]

virtual xAOD::TrackParticle * Trk::ITrackParticleCreatorTool::createParticle ( const EventContext & ctx, const Trk::Track & track, xAOD::TrackParticleContainer * container = nullptr, const xAOD::Vertex * vxCandidate = nullptr, xAOD::ParticleHypothesis prtOrigin = xAOD::noHypothesis ) const

pure virtual

Method to construct a TrackParticle from a passed Track.

Parameters

track	element link to the track is not set, use the method with the element link if you want the link as well
TrackParticleContainer	needed to have an AuxStore, if provided particle will be added to store which takes ownership
xAOD::Vertex	Pointer to a vxCandidate . Ownership is not taken
prtOrigin	hits.
