CGAL 4.7  2D Regularized Boolean SetOperations

Operations  
Output_iterator  operator() (ArrDirectionalTraits::X_monotone_curve_2 xc1, ArrDirectionalTraits::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 . More...  
Output_iterator ArrDirectionalTraits::Intersect_2::operator()  (  ArrDirectionalTraits::X_monotone_curve_2  xc1, 
ArrDirectionalTraits::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 valuetype of Output_iterator
is CGAL::Object
, where each Object
wraps either a pair<ArrDirectionalTraits::Point_2, ArrDirectionalTraits::Multiplicity>
object, which represents an intersection point with its multiplicity (in case the multiplicity is undefined or unknown, it is set to \( 0\)) or an ArrDirectionalTraits::X_monotone_curve_2
object, representing an overlapping subcurve of xc1
and xc2
. In the latter case, the overlapping subcurves are given the direction of xc1
and xc2
if their directions are identical. Otherwise, the overlapping subcurves are given an arbitrary direction. The operator returns a pasttheend iterator for the output sequence.
