class THaFormula: public TFormula


 A formula that is aware of the analyzer's global variables, similar
 to TFormula;s parameters. Unlike TFormula, an arbitrary number of
 global variables may be referenced in a THaFormula.

 THaFormulas containing arrays are arrays themselves. Each element
 (instance) of such an array formula may be evaluated separately.

Function documentation

 Default constructor
THaFormula(const char* name, const char* formula, Bool_t do_register = kTRUE, const THaVarList* vlst = gHaVars, const THaCutList* clst = gHaCuts)
 Create a formula 'expression' with name 'name' and symbolic variables
 from the list 'lst'.
Int_t Init(const char* name, const char* expression)
 Common initialization called from the constructors
THaFormula(const THaFormula& rhs)
 Copy ctor
THaFormula& operator=(const THaFormula& rhs)
Int_t Compile(const char* expression = "")
 Parse the given expression, or, if empty, parse the title.
 Return 0 on success, 1 if error in expression.
char* DefinedString(Int_t i)
 Get pointer to the i-th string variable. If the variable is not
 a string, return pointer to an empty string.
Bool_t IsString(Int_t oper) const
Double_t DefinedValue(Int_t i)
 Get value of i-th variable in the formula
 If the i-th variable is a cut, return its last result
 (calculated at the last evaluation).
 If the variable is a string, return value of its character value
Int_t DefinedVariable(TString& variable, Int_t& action)
 Check if name is in the list of global objects
Int_t DefinedCut(TString& variable)
 Check if 'name' is a known cut. If so, enter it in the local list of
 variables used in this formula.
Int_t DefinedGlobalVariable(TString& variable)
 Check if 'name' is a known global variable. If so, enter it in the
 local list of variables used in this formula.
Int_t DefinedSpecialFunction(TString& name)
 Check if 'name' is a predefined special function
