ROOT::Math::FunctorHandler< ParentFunctor, Func > Class Template Reference

template<class ParentFunctor, class Func>
class ROOT::Math::FunctorHandler< ParentFunctor, Func >

Functor Handler class is responsible for wrapping any other functor and pointer to free C functions.

It can be created from any function implementing the correct signature corresponding to the requested type In the case of one dimension the function evaluation object must implement double operator() (double x). If it implements a method: double Derivative(double x) can be used to create a Gradient function type.

In the case of multi-dimension the function evaluation object must implement double operator()(const double *x). If it implements a method: double Derivative(const double *x, int icoord) can be used to create a Gradient function type.
