Class Description


RooFormula() : TFormula(), _nset(0)
 Dummy constructor

RooFormula(const char* name, const char* formula, const RooArgList& list) : TFormula(), _isOK(kTRUE), _compiled(kFALSE)
 Constructor with expression string and list of variables

RooFormula(const RooFormula& other, const char* name) : TFormula(), RooPrintable(other), _isOK(other._isOK), _compiled(kFALSE)
 Copy constructor

Bool_t reCompile(const char* newFormula)
 Recompile formula with new expression

~RooFormula()
 Destructor

RooArgSet& actualDependents() const

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) const
 Print info about this argument set to the specified stream.

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