class THaFormula: public TFormula


     A THaFormula defines cuts and histogram expressions
     for the Hall A analyzer

  A THaFormula can contain any arithmetic expression including
  standard operators and mathematical functions separated by operators.
  Examples of valid expression:
          "x<y && sqrt(z)>3.2"

Function documentation

THaFormula(const char* name, const char* formula, const THaVarList* vlst = gHaVars, const THaCutList* clst = gHaCuts)
 Create a formula 'expression' with name 'name' and symbolic variables
 from the list 'lst'.
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.
~THaFormula()
 Destructor
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(const 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(const TString& variable)
 Check if 'name' is a known global variable. If so, enter it in the
 local list of variables used in this formula.
Double_t Eval( void )
 Evaluate this formula
TString GetExpFormula(Option_t* opt = "") const
 Override ROOT's TFormula::GetExpFormula because it does not handle
 kDefinedVariable and kDefinedString opcodes.
 For our purposes, the un-expanded expression is good enough
void Print(Option_t* option = "") const
 Print this formula to stdout
 Options:
   "BRIEF" -- short, one line
   "FULL"  -- full, multiple lines
THaFormula(const THaFormula& rhs)
{}
Double_t Eval()
Bool_t IsError()
{ return fError; }
void SetList(const THaVarList* lst)
