Operations
A model of this concept must provide:
Comparison_result	operator() (const AosTraits::Point_2 &p1, const AosTraits::Point_2 &p2)
	Given two points p1 and p2, such that either p1 or p2 (or both) lie on the bottom or top boundary of the parameter space, compares the \( x\)-coordinate of p1 and the \(x\)-coordinate of p2.

Member Function Documentation

operator()()

Comparison_result AosTraits::CompareXOnBoundary_2::operator()	(	const AosTraits::Point_2 &	p1,
		const AosTraits::Point_2 &	p2
	)

Given two points p1 and p2, such that either p1 or p2 (or both) lie on the bottom or top boundary of the parameter space, compares the \( x\)-coordinate of p1 and the \(x\)-coordinate of p2.

Returns CGAL::SMALLER, CGAL::EQUAL, or CGAL::LARGER accordingly.

Precondition

Parameter_space_in_y_2 (p1) \(\neq\) CGAL::ARR_INTERIOR or Parameter_space_in_y_2 (p2) \(\neq\) CGAL::ARR_INTERIOR.
