Kernel::Point_2 Kernel::ConstructPoint_2::operator()

(

returns p.

Note

It is advised to return a const reference to p to avoid useless copies.

This peculiar requirement is necessary because some CGAL structures such as triangulations internally manipulate points whose type might be Point_2 or Weighted_point_2.
