Documentation for class Functor class.
It is used to wrap in a very simple and convenient way multi-dimensional function objects. It can wrap all the following types:
-
any C++ callable object implementation double operator()( const double * )
-
a free C function of type double ()(const double * )
-
an std::function of type std::function<double (double const *)>
-
a member function with the correct signature like Foo::Eval(const double * ). In this case one pass the object pointer and a pointer to the member function (&Foo::Eval)
The function dimension is required when constructing the functor.

| | Functor (const PtrObj &p, MemFn memFn, unsigned int dim) |
| | Construct from a pointer to member function (multi-dim type).
|
| |
| | Functor (std::function< double(double const *)> const &f, unsigned int dim) |
| | Construct from a callable object of multi-dimension with the right signature (implementing double operator()(const double *x)).
