Class Description


RooFormulaVar(const char *name, const char *title, const char* formula, const RooArgList& dependents) : RooAbsReal(name,title), _actualVars("actualVars","Variables used by formula expression",this), _formula(0), _formExpr(formula)
 Constructor with formula expression and list of input variables
   RooFormula tmpFormula(name,formula,dependents) ;

RooFormulaVar(const char *name, const char *title, const RooArgList& dependents) : RooAbsReal(name,title), _actualVars("actualVars","Variables used by formula expression",this), _formula(0), _formExpr(title)
 Constructor with formula expression, title and list of input variables
   RooFormula tmpFormula(name,title,dependents) ;

RooFormulaVar(const RooFormulaVar& other, const char* name) : RooAbsReal(other, name), _actualVars("actualVars",this,other._actualVars), _formula(0), _formExpr(other._formExpr)
 Copy constructor

~RooFormulaVar()
 Destructor

RooFormula& formula() const

Double_t evaluate() const
 Calculate current value of object

Bool_t isValidReal(Double_t /*value*/, Bool_t /*printError*/) const
 Check if given value is valid

Bool_t redirectServersHook(const RooAbsCollection& newServerList, Bool_t mustReplaceAll, Bool_t nameChange, Bool_t /*isRecursive*/)
 Propagate server change information to embedded RooFormula object

void printToStream(ostream& os, PrintOption opt, TString indent) const
 Print info about this object to the specified stream.

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 object contents to given stream

Double_t defaultErrorLevel() const
 See if we contain a RooNLLVar or RooChi2Var object
