void dump()


 DEBUG: Dump state information



Bool_t changeDependents(const RooAbsCollection& newDeps, Bool_t mustReplaceAll, Bool_t nameChange)


 Change used variables to those with the same name in given list



Double_t eval(const RooArgSet* nset)


 Return current value of formula



 DefinedValue(Int_t code)


 Return current value for variable indicated by internal reference code



 DefinedVariable(TString &name, int& action)




 DefinedVariable(TString &name)


 Check if a variable with given name is available



void printToStream(ostream& os, PrintOption opt, TString indent)


 Print info about this argument set to the specified stream.

   OneLine: use RooPrintable::oneLinePrint()
  Standard: our formula
   Verbose: formula and list of actual dependents



TObject* Clone(const char* newName=0)




RooAbsArg* getParameter(const char* name)




RooAbsArg* getParameter(Int_t index)




Bool_t ok()


 Function value accessor



void Print(Option_t *options= 0)




RooFormula& operator=(const RooFormula& other)




void initCopy(const RooFormula& other)
