Function documentation

~THaTrack()
 Destructor. Delete the track ID associated with this track.
void Clear(Option_t* opt = "")
 If *opt == 'F' then reset all track quantities, else just
 delete memory managed by this track.
 (We need this behavior so we can Clear("C") the track TClonesArray
 without the overhead of clearing everything.)
Int_t AddCluster(THaCluster* c)
 Add a cluster to the internal list of pointers.
 (Clusters are memory-managed by tracking detectors, not by tracks.)
void Print(Option_t* opt = "") const
 Print track parameters
Int_t Compare(const TObject* obj) const
 compare two tracks by chi2/ndof
 for track array sorting
void SetD(Double_t x, Double_t y, Double_t theta, Double_t phi)
 set the coordinates in the rotated focal-plane frame
void SetR(Double_t x, Double_t y, Double_t theta, Double_t phi)
 set the coordinates in the rotated focal-plane frame
void SetTarget(Double_t x, Double_t y, Double_t theta, Double_t phi)
 set the coordinates in the target frame
