class HPidAlgorithm: public TObject

_HADES_CLASS_DESCRIPTION


 HPidAlgorithm

 A base class for all PID algorithms
 The algorithms are identified by their id (iAlgId) or/and by their name (sName).
 The flag fWeight is not used up to know, but is dedicated for the future
 extensions (different weights of algorithms)

Function documentation

HPidAlgorithm(const HPidAlgorithm& )
 Default constructor
HPidAlgorithm(TString sName, Int_t iAlgId)
 Constructor with the name and id of the algorithm
HPidAlgorithm(TString sName, Int_t iAlgId, Float_t fWeight)
 Constructor with the name, id and weight of the algorithm
~HPidAlgorithm(void)
 Destructor. The algorithm calls pRec->removeAlgorithm(this) to remove
 itself from the list of the algorithms.
Bool_t init(void)
 Abstract method for initialization. Returns status of the initialization.
Bool_t reinit(void)
 Abstract method for reinitialization. Returns status of the reinitialization.
Bool_t finalize(void)
 Abstract method for finalizing. Returns status of the finalizing.
Bool_t execute(HPidTrackCand* pTrack, Float_t* afReturnPDF, Float_t* afReturnCL, Short_t& nCatIndex)
 Method for pid finding.
 pTrack      - pointer to the track candidate for which a statement must be given
 afReturnPDF - array for PDF values; the size taken from the PidReconstructor class
 afReturnCL  - array for CL values; the size taken from the PidReconstructor class
 nCatIndex   - index of an object in category used by algorithm
               (eg. HShowerPid) default set to -1

 afReturnPDF and afReturnCL are used to store the result of this algorithms computation for
 the outside world
Bool_t calculatePDF(HPidTrackCand* pTrack, Float_t* afReturn, Short_t& nCatIndex)
 pTrack    - pointer to the track candidate
 afReturn  - array for return values; the size taken from the reconstructor
 nCatIndex - index of an object in category used by algorithm (eg. HShowerPid)
             default set to -1

 Returns status of the calculations.
Bool_t calculateCL(HPidTrackCand* pTrack, Float_t* afReturn, Short_t& nCatIndex)
 Abstract method for calculating CL (returns kTRUE)
 For description see calculatePDF()
void print(void)
 Empty function for printing info of the algorithm
HPidAlgorithm(const HPidAlgorithm& )
HPidReconstructor* getReconstructor(void)
getters and setters will not be documented unless required
{ return pRec; }
const TString& getName(void)
{ return sName; }
Int_t getAlgId(void)
{ return iAlgId; }
Float_t getWeight(void)
{ return fWeight; }
void setWeight(Float_t f)
    Bool_t              getMerge(void) const         { return bMerge;          }
    void                setMerge(Bool_t b)           { bMerge = b;             }
{ fWeight = f; }
void Print(Option_t* option = "") const
{ print(); }
void setReconstructor(HPidReconstructor* pRec)
Bool_t            bMerge;     // algorithm should be used when merging different algorithms into one decision
{ this->pRec = pRec;}
