CGAL::Arity_traits<F>
Definition
The class Arity_traits<F> is used to define the arity of a
functor class F, i.e., the number of arguments it takes. It is
used as a compile time tag only, that is objects of this type are
never created anywhere. Specializations of Arity_traits<F> can be
defined, where existing functors cannot be changed easily to contain
their Arity type.
