◆ operator()()

Output_iterator ArrTraits::Intersect_2::operator() ( ArrTraits::X_monotone_curve_2  xc1,
ArrTraits::X_monotone_curve_2  xc2,
Output_iterator &  oi 
)

computes the intersections of xc1 and xc2 and inserts them in an ascending lexicographic \( xy\)-order into the output iterator oi.

The value-type of Output_iterator is CGAL::Object, where each Object wraps either a pair<ArrTraits::Point_2,ArrTraits::Multiplicity> object, which represents an intersection point with its multiplicity (in case the multiplicity is undefined or unknown, it should be set to \( 0\)) or an ArrTraits::X_monotone_curve_2 object, representing an overlapping subcurve of xc1 and xc2. The operator returns a past-the-end iterator for the output sequence.
