◆ operator()()

Comparison_result ArrTraits::CompareYOnBoundary_2::operator() ( const ArrTraits::Point_2 p1,
const ArrTraits::Point_2 p2 
)

Given two points p1 and p2 returns CGAL::SMALLER, CGAL::EQUAL, or CGAL::LARGER according to the lexicographic \(xy\)-order of the points p1 and p2.

Precondition
Parameter_space_in_x_2 (p1) \(\neq\) CGAL::ARR_INTERIOR or Parameter_space_in_x_2 (p2) \(\neq\) CGAL::ARR_INTERIOR.
