Constructor & Destructor Documentation

template<typename Point_2 , typename Creator >
CGAL::Random_points_on_square_2< Point_2, Creator >::Random_points_on_square_2 ( double  a,
Random &  rnd = default_random 
)

creates an input iterator g generating points of type Point_2 uniformly distributed on the boundary of the square with side length 2a, centered at the origin, i.e. ∀p=∗g: one coordinate is either a or −a and for the other coordinate c holds −a≤c<a.

A single random number is needed from rnd for each point.
