OverlayVisitor Concept Reference Definition A model of the OverlayVisitor concept contains callback functions invoked while the overlay operation of two input arrangements progresses. Models of the concept are used by the free function CGAL::Arrangement_on_curve_1::overlay() to maintain the auxiliary data stored with the cells (i.e., vertices and edges) of the resulting overlaid arrangement, based on the contents of the input cells.
