Detailed Description

template<class Ftor>
class rpa::unary_function_count< Ftor >

Counts the number of times that a functor was called.

This allows to check that algorithms work correctly : Typically, a functor must be called once per input element, whatever the number of threads is, or if the algorithm is called sequentially. Therefore, we can have a better proof that at the end of a parallel computation, things worked properly.
