virtual EVENT::Track::~Track (   )  [inline, virtual]
 

Destructor.

Definition at line 32 of file Track.h.

Member Function Documentation

virtual LCObject* EVENT::LCObject::clone (   )  const [inline, virtual, inherited]
 

Deep copy of the object. C++ implementations should return the concrete type (virtual constructor). No reasonable implementation yet. Do not use this method.

Reimplemented in IMPL::SimCalorimeterHitImpl.

Definition at line 52 of file LCObject.h.

template<class V>
V::ext_type lcrtrel::LCRTRelations::ext (   )  [inline, inherited]
 

Provides access to an extension object - the type and ownership is defined by the class V which should be a subtype of LCExtension, LCOwnedExtension, LCExtensionVector, LCExtensionList,...

Definition at line 430 of file LCRTRelations.h.

virtual float EVENT::Track::getChi2 (   )  const [pure virtual]
 

Chi^2 of the track fit.

Implemented in IMPL::TrackImpl.

Referenced by UTIL::LCTOOLS::printTracks(), and SIO::SIOTrackHandler::write().

virtual const FloatVec& EVENT::Track::getCovMatrix (   )  const [pure virtual]
 

Covariance matrix of the track parameters. Stored as lower triangle matrix where the order of parameters is: d0, phi, omega, z0, tan(lambda). So we have cov(d0,d0), cov( phi, d0 ), cov( phi, phi), ...

Implemented in IMPL::TrackImpl.

Referenced by UTIL::LCTOOLS::printTracks(), and SIO::SIOTrackHandler::write().

virtual float EVENT::Track::getD0 (   )  const [pure virtual]
 

Impact paramter of the track in (r-phi).

Implemented in IMPL::TrackImpl.

Referenced by UTIL::LCTOOLS::printTracks(), and SIO::SIOTrackHandler::write().

virtual float EVENT::Track::getdEdx (   )  const [pure virtual]
 

dEdx of the track.

Implemented in IMPL::TrackImpl.

Referenced by UTIL::LCTOOLS::printTracks(), and SIO::SIOTrackHandler::write().

virtual float EVENT::Track::getdEdxError (   )  const [pure virtual]
 

Error of dEdx.

Implemented in IMPL::TrackImpl.

Referenced by UTIL::LCTOOLS::printTracks(), and SIO::SIOTrackHandler::write().

virtual int EVENT::Track::getNdf (   )  const [pure virtual]
 

Number of degrees of freedom of the track fit.

Implemented in IMPL::TrackImpl.

Referenced by SIO::SIOTrackHandler::write().

virtual float EVENT::Track::getOmega (   )  const [pure virtual]
 

Omega is the signed curvature of the track in [1/mm]. The sign is that of the particle's charge.

Implemented in IMPL::TrackImpl.

Referenced by UTIL::LCTOOLS::printTracks(), and SIO::SIOTrackHandler::write().

virtual float EVENT::Track::getPhi (   )  const [pure virtual]
 

Phi of the track at the reference point.

See also:
getReferencePoint

Implemented in IMPL::TrackImpl.

Referenced by UTIL::LCTOOLS::printTracks(), and SIO::SIOTrackHandler::write().

virtual float EVENT::Track::getRadiusOfInnermostHit (   )  const [pure virtual]
 

The radius of the innermost hit that has been used in the track fit. Helps to detect V0 tracks with small impact paramters or heavy mesons. To be used as convenient information or if hits are not stored in the data set, e.g. DST or FastMC.

Implemented in IMPL::TrackImpl.

Referenced by UTIL::LCTOOLS::printTracks(), and SIO::SIOTrackHandler::write().

virtual const float* EVENT::Track::getReferencePoint (   )  const [pure virtual]
 

Reference point of the track parameters. The default for the reference point is the point of closest approach.

See also:
isReferencPointPCA()

Implemented in IMPL::TrackImpl.

Referenced by UTIL::LCTOOLS::printTracks(), and SIO::SIOTrackHandler::write().

virtual const IntVec& EVENT::Track::getSubdetectorHitNumbers (   )  const [pure virtual]
 

A vector that holds the number of hits in particular subdetectors. The mapping of indices to subdetectors is implementation dependent. To be used as convenient information or if hits are not stored in the data set, e.g. DST or FastMC. Check/set collection variable TrackSubdetectorNames for decoding the indices.

Implemented in IMPL::TrackImpl.

Referenced by UTIL::LCTOOLS::printTracks(), and SIO::SIOTrackHandler::write().

virtual float EVENT::Track::getTanLambda (   )  const [pure virtual]
 

Lambda is the dip angle of the track in r-z at the reference point.

See also:
getReferencePoint

Implemented in IMPL::TrackImpl.

Referenced by UTIL::LCTOOLS::printTracks(), and SIO::SIOTrackHandler::write().

virtual const TrackerHitVec& EVENT::Track::getTrackerHits (   )  const [pure virtual]
 

Optionaly ( check/set flag(LCIO::TRBIT_HITS)==1) return the hits that have been used to create this track.

Implemented in IMPL::TrackImpl.

Referenced by UTIL::LCTOOLS::printTracks(), and SIO::SIOTrackHandler::write().

virtual const TrackVec& EVENT::Track::getTracks (   )  const [pure virtual]
 

The tracks that have been combined to this track.

Implemented in IMPL::TrackImpl.

Referenced by UTIL::LCTOOLS::printTracks(), and SIO::SIOTrackHandler::write().

virtual int EVENT::Track::getType (   )  const [pure virtual]
 

Flagword that defines the type of track. Bits 0-15 can be used to denote the subdetectors that have contributed hits used in the track fit. For the definition of the bits check/Set the collection variables TrackTypeBitNames and TrackTypeBitIndices. Bits 16-31 are used internally.

Implemented in IMPL::TrackImpl.

Referenced by UTIL::LCTOOLS::printTracks(), and SIO::SIOTrackHandler::write().
