CGAL::ch_we_point

Definition

The function ch_we_point finds two points of a given set of input points with minimal and maximal $$x coordinates.

#include <CGAL/ch_selected_extreme_points_2.h>

template <class ForwardIterator>
void	ch_we_point ( ForwardIterator first, ForwardIterator beyond, ForwardIterator& w, ForwardIterator& e, Traits ch_traits = Default_traits)
		traverses the range [first,beyond). After execution, the value of w is an iterator in the range such that *w $$ xy *it for all iterators it in the range. Similarly, for e the inequality *e $$ xy *it holds for all iterators in the range.

The default traits class Default_traits is the kernel in which the type ForwardIterator::value_type is defined.
