## CGAL::set_arity_0

### Definition

The function set_arity_0 is used to set the arity of a functor to zero. The result is a functor that takes no arguments and calls the original functor with no arguments.

#include <CGAL/functional.h>

template < class F >
Set_arity< F, 0 >::Type
| set_arity_0 ( F f)
|  | returns a functor equivalent to f, but which has arity zero. Requirement: F is a model for AdaptableFunctor.
