### Definition

The class Set_arity<F,a> is used to specify the type of a functor of type F whose arity has been set explicitly to a. The class is used in conjunction with the set_arity functions.

#include <CGAL/functional.h>

### Types

Set_arity<F,a>::Type

### Notes

This class encapsulates the differences in implementation across various platforms. But in any case, Type refers to a model of AdaptableFunctor with arity a.
