Function documentation

~AliVertexer()

 Default Destructor

void SetVtxStart(AliESDVertex* vtx)

 Set initial vertex knowledge

AliESDVertex* FindVertexForCurrentEvent(TTree* clustersTree)

 computes the vertex for the current event

AliMultiplicity* GetMultiplicity() const

 computes the vertex for each event and stores it on file

{return fMult;}

void PrintStatus() const

void SetVtxStart(Double_t x, Double_t y, Double_t z)

{ fNominalPos[0]=x; fNominalPos[1]=y; fNominalPos[2]=z; }

void SetVtxStartSigma(Double_t sx, Double_t sy, Double_t sz)

AliESDVertex* GetAllVertices(Int_t& novertices) const

 the following method can be implemented in daughter classes
 (e.g. in AliITSVertexer3D). It is intended to tag pile-up events
 novertices is the total number of vertices (1 means no pileup)
 The returned pointer points to an array of AliESDVertx opbjects
 with size=novertices

{novertices = 0; return NULL;}

const Double_t* GetNominalPos() const

{return fNominalPos;}

const Double_t* GetNominalCov() const

{return fNominalCov;}
