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
