Class Description

 RooErrorVar is an auxilary class that represents the error
 of a RooRealVar as a seperate object. The main reason of
 existence of this class is to facilitate the reuse of existing
 techniques to perform calculations that involve a RooRealVars
 error, such as calculating the pull value.

RooErrorVar(const char *name, const char *title, const RooRealVar& input) : RooAbsRealLValue(name,title), _realVar("realVar","RooRealVar with error",this,(RooAbsReal&)input)

RooErrorVar(const RooErrorVar& other, const char* name) : RooAbsRealLValue(other,name), _realVar("realVar",this,other._realVar)

~RooErrorVar()

 Destructor

Double_t getVal(const RooArgSet*) const

Bool_t hasBinning(const char* name) const

const RooAbsBinning& getBinning(const char* name, Bool_t verbose, Bool_t createOnTheFly) const

RooAbsBinning& getBinning(const char* name, Bool_t verbose, Bool_t createOnTheFly)

 Return default (normalization) binning and range if no name is specified

void setBinning(const RooAbsBinning& binning, const char* name)

void setMin(const char* name, Double_t value)

 Set new minimum of fit range

void setMax(const char* name, Double_t value)

 Set new maximum of fit range

void setRange( const char* name, Double_t min, Double_t max)

Bool_t readFromStream(istream& is, Bool_t /*compact*/, Bool_t verbose)

 Read object contents from given stream

void writeToStream(ostream& os, Bool_t /*compact*/) const

 Write value only

void syncCache(const RooArgSet*)
