class RooDataProjBinding: public RooRealBinding

Class RooDataProjBinding is a lightweight interface adaptor that projects a real function via summation of states provided in a dataset. The real function must be attached to the dataset before creating this binding object. If the dataset only contains category variables, the summation is optimized performing a weighted sum over the states of a RooSuperCategory that is constructed from all the categories in the dataset

Function documentation

RooDataProjBinding(const RooAbsReal& real, const RooAbsData& data, const RooArgSet& vars, const RooArgSet* normSet = 0)

 Constructor of a data weighted average function binding with
 variables 'vars' for function 'real' and dataset 'data' with
 weights.

~RooDataProjBinding()

 Destructor, delete owned objects

Double_t operator()(const Double_t* xvector) const

 Evaluate data-projected values of the bound real function.
