HepVertex

Function documentation

HepVertex()

 Default constructor

HepVertex(Int_t Id, Float_t X, Float_t Y, Float_t Z, Float_t Chi2, Int_t NDoF)

 Normal constructor

~HepVertex()

 Default destructor

void Clear(Option_t* option = "")

 Clear this object

void AddDaughter(HepVtxTrackHelix* trk)

 Add outgoing helix to the list of daughters
 and set this vertex as mother in the track object

void Print(Option_t* option = "") const

 Print object information

 Options available:
   "daughters" - Print all daughter tracks also
   "nohead"    - No header containing the variable names is
                 displayed. Useful when printing a whole table
                 for a list of vertices

void PrintHeader()

 Print information header

void PrintFooter()

 Print footer

TString* GetVtxTypeStr() const

 Return character string of vertex type(s)

Int_t Compare(const TObject* obj) const

 Compares chi2/ndof of this vertex with another.
 Necessary for sorting

HepVertex()

const TVector3& GetPos() const

{ return fPos; }

TRefArray* GetDaughters() const

{ return fDaughters; }

Int_t GetNDaughters() const

 Return no. of daughter tracks
 In case of a filled daughter array simply the no. of
 entries is returned. In some case (e.g. when reading from DPDs) those
 arrays are not filled. Here, the data member fNDaughters is used.

Float_t GetChi2() const

{ return fChi2; }

Int_t GetNDoF() const

{ return fNDoF; }

Float_t GetChi2overNDoF() const

{ return fChi2/fNDoF; }

Int_t GetId()

{ return fId; }

EType GetType() const

{ return fType; }

Bool_t IsInvalid() const

{ return fType & kInvalid; }
