Detailed Description

This class allows access to the genfit::Track of the RecoTrack.

This class allows direct access to the most holy part of the RecoTrack. The design of the RecoTrack is such, that this should not be required. However, some interfaces require a genfit::Track, e.g. the genfit rave interface, and the access to the genfit::Track member is required. This should only be used when no other solution works.

Member Function Documentation

createOrReturnRKTrackRep()

genfit::AbsTrackRep * createOrReturnRKTrackRep ( RecoTrack &  recoTrack, int  PDGcode  )

static

Checks if a TrackRap for the PDG id of the RecoTrack (and its charge conjugate) does already exit and returns it if available.

If no TrackRep is available, a new RKTrackRep is added to the genfit::Track. This ensures that a TrackRep with the same PDG id (and its charge conjugate) is not available two times in the genfit::Track.

By convention, only one TrackRep for one particle type can exist inside of a RecoTrack, no matter the charge. So there can only be a electron or positron TrackRep, but not both.

Parameters

recoTrack	Track to add TrackRep to
PDGcode	: code of the hypothesis which is negative or positive, depending on the charge of the hypothesis particle.

{
  // try to get the trackRep, if it has already been added
  genfit::AbsTrackRep* trackRepresentation = recoTrack.getTrackRepresentationForPDG(std::abs(PDGcode));
 
  // not available? create one
  if (trackRepresentation == nullptr) {
    if (PDGcode == Monopoles::c_monopolePDGCode) {
      trackRepresentation = new genfit::MplTrackRep(PDGcode, Monopoles::monopoleMagCharge);
    } else {
      trackRepresentation = new genfit::RKTrackRep(PDGcode);
    }
    RecoTrackGenfitAccess::getGenfitTrack(recoTrack).addTrackRep(trackRepresentation);
  }
  return trackRepresentation;
}

getGenfitTrack()

genfit::Track & getGenfitTrack ( RecoTrack &  recoTrack )

static

Give access to the RecoTrack's genfit::Track.

Parameters

recoTrack

Track to unpack

Returns

genfit::Track of the RecoTrack.

Definition at line 404 of file RecoTrack.cc.

{
  return recoTrack.m_genfitTrack;
}

swapGenfitTrack()

void swapGenfitTrack ( RecoTrack &  recoTrack, const genfit::Track *  track  )

static

Set the genfit track of a Recotrack copying the information from another genfit track.

This is used by the fit&refit, since the original genfit track must be updated with the refitted object obtained after the flip

Parameters

recoTrack	: RecoTrack whose Track we want to update
track	: input genfit::Track which we want to copy inside the RecoTrack

{
  recoTrack.m_genfitTrack = *track;
