Class Description

 Class RooRealSumPdf implements a PDF constructed from a sum of
 real valued objects, i.e.

                 Sum(i=1,n-1) coef_i * func_i(x) + [ 1 - (Sum(i=1,n-1) coef_i ] * func_n(x)
   pdf(x) =    ------------------------------------------------------------------------------
             Sum(i=1,n-1) coef_i * Int(func_i)dx + [ 1 - (Sum(i=1,n-1) coef_i ] * Int(func_n)dx


 where coef_i and func_i are RooAbsReal objects, and x is the collection of dependents.
 In the present version coef_i may not depend on x, but this limitation will be removed in the future

RooRealSumPdf(const char *name, const char *title) : RooAbsPdf(name,title), _codeReg(10), _lastFuncIntSet(0), _lastFuncNormSet(0), _funcIntList(0), _funcNormList(0), _haveLastCoef(kFALSE), _funcList("funcList","List of functions",this), _coefList("coefList","List of coefficients",this)

 Dummy constructor

RooRealSumPdf(const char *name, const char *title, RooAbsReal& func1, RooAbsReal& func2, RooAbsReal& coef1) : RooAbsPdf(name,title), _codeReg(10), _lastFuncIntSet(0), _lastFuncNormSet(0), _funcIntList(0), _funcNormList(0), _haveLastCoef(kFALSE), _funcList("funcProxyList","List of functions",this), _coefList("coefList","List of coefficients",this)

 Special constructor with two functions and one coefficient

RooRealSumPdf(const char *name, const char *title, const RooArgList& funcList, const RooArgList& coefList) : RooAbsPdf(name,title), _codeReg(10), _lastFuncIntSet(0), _lastFuncNormSet(0), _funcIntList(0), _funcNormList(0), _haveLastCoef(kFALSE), _funcList("funcProxyList","List of functions",this), _coefList("coefList","List of coefficients",this)

 Constructor from list of functions and list of coefficients.
 Each func list element (i) is paired with coefficient list element (i).
 The number of coefficients must be one less than to the number of functions,

 All functions and coefficients must inherit from RooAbsReal.

RooRealSumPdf(const RooRealSumPdf& other, const char* name) : RooAbsPdf(other,name), _codeReg(other._codeReg), _lastFuncIntSet(0), _lastFuncNormSet(0), _funcIntList(0), _funcNormList(0), _haveLastCoef(other._haveLastCoef), _funcList("funcProxyList",this,other._funcList), _coefList("coefList",this,other._coefList)

 Copy constructor

~RooRealSumPdf()

 Destructor

Double_t evaluate() const

 Calculate the current value

Bool_t checkObservables(const RooArgSet* nset) const

 Check if FUNC is valid for given normalization set.
 Coeffient and FUNC must be non-overlapping, but func-coefficient
 pairs may overlap each other

 For the moment, coefficients may not be dependents or derive
 from dependents

Int_t getAnalyticalIntegralWN(RooArgSet& allVars, RooArgSet& analVars, const RooArgSet* normSet2, const char* /*rangeName*/) const

 Handle trivial no-integration scenario

Double_t analyticalIntegralWN(Int_t code, const RooArgSet* normSet2, const char* /*rangeName*/) const

 Handle trivial passthrough scenario

void syncFuncIntList(const RooArgSet* intSet) const

void syncFuncNormList(const RooArgSet* normSet) const
