CGAL::ch_we_point
Definition
The function ch_we_point finds two points of a given set
of input points with minimal and maximal coordinates.

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
*it for all iterators it in the range. Similarly, for
e the inequality *e *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.
Requirements
Traits defines the type Traits::Less_xy_2 as specified in
the concept ConvexHullTraits_2 and the corresponding member
function that returns an instance of this type.
