ROOT::v5::TFormulaPrimitive Class Reference

The Formula Primitive class.

Helper class for TFormula to speed up TFormula evaluation TFormula can use all functions registered in the list of TFormulaPrimitives User can add new function to the list of primitives if FormulaPrimitive with given name is already defined new primitive is ignored

Example:

  • TFormulaPrimitive is used to get direct acces to the function pointers
  • GenFunc - pointers to the static function
  • TFunc - pointers to the data member functions

The following sufixes are currently used, to describe function arguments:

  • G - generic layout - pointer to double (arguments), pointer to double (parameters)
  • 10 - double
  • 110 - double, double
  • 1110 - double, double, double
