### Data Members

        protected:

          RooCategoryProxy _cat         Accept/reject categort
              RooRealProxy _effFunc     Efficiency modeling function
                   TString _sigCatName  Name of accept state of accept/reject category

## Class Description

     Given a dataset with a category C that determines if a given
     event is accepted or rejected for the efficiency to be measured,
     this class evaluates as F if C is 'accept' and as (1-F) if
     C is 'reject'. Values of F below 0 and above 1 are clipped.
     F may have an arbitrary number of dependents and parameters

RooEfficiency(const char *name, const char *title, const RooAbsReal& effFunc, const RooAbsCategory& cat, const char* sigCatName) : RooAbsPdf(name,title), _cat("cat","Signal/Background category",this,(RooAbsCategory&)cat), _effFunc("effFunc","Efficiency modeling function",this,(RooAbsReal&)effFunc), _sigCatName(sigCatName)

     Constructor with title used as formula expression

RooEfficiency(const RooEfficiency& other, const char* name) : RooAbsPdf(other, name), _cat("cat",this,other._cat), _effFunc("effFunc",this,other._effFunc), _sigCatName(other._sigCatName)

     Copy constructor

~RooEfficiency()

     Destructor

Double_t evaluate() const

     Calculate current value of this object
