Int_t DistancetoPrimitive(Int_t px, Int_t py)
*-*-*-*-*-*-*-*Compute distance from point px,py to a primary track*-*-*-*
*-* ====================================================
*-*
*-* Compute the closest distance of approach from point px,py to each segment
*-* of a track.
*-* The distance is computed in pixels units.
*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
void ExecuteEvent(Int_t, Int_t, Int_t)
*-*-*-*-*-*-*-*-*-*-*Execute action corresponding to one event*-*-*-*
*-* =========================================
const char* GetName() const
TParticlePDG* GetPDG(Int_t mode)
returns a pointer to the TParticlePDG object using the pdgcode
if mode == 0 (default) always get a fresh value for the pointer.
if mode != 0 this function returns directly the previously
computed pointer from a previous call
One can use mode=1 (faster) when the TParticle object is not part of a
TClonesArray used in split mode in a Root TTree.
void GetPolarisation(TVector3 &v)
const char* GetTitle() const
void Paint(Option_t *option)
Paint a primary track
void Print(Option_t *) const
Print the internals of the primary vertex particle
TParticlePDG* pdg = ((TParticle*)this)->GetPDG();
void SetPolarisation(Double_t polx, Double_t poly, Double_t polz)
void Sizeof3D() const
*-*-*-*-*-*Return total X3D size of this primary*-*-*-*-*-*-*
*-* =====================================
void Streamer(TBuffer &R__b)
Stream an object of class TParticle.
