OutputIterator

intersection ( Type1 p1, Type2 p2, OutputIterator oi)

Each one of these functions computes the symmetric difference between two given polygons p1 and p2, and inserts the resulting polygons with holes into an output container through the output iterator oi. The value type of the OutputIterator is either Polygon_with_holes_2 or General_polygon_with_holes_2.

OutputIterator

symmetric_difference ( InputIterator begin, InputIterator end, OutputIterator oi)

Computes the symmetric difference of the general polygons (or general polygons with holes) in the given range. A point is contained in the symmetric difference, if and only if it is contained in odd number of input polygons. (The value type of the input iterator is used to distinguish between the two.) The result, represented by a set of general poygon with holes, is inserted into an output container through a given output iterator oi. The output iterator is returned. The value type of the OutputIterator is Traits::Polygon_with_holes_2.

OutputIterator

symmetric_difference ( InputIterator1 pgn_begin1,
InputIterator1 pgn_end1,
InputIterator2 pgn_begin2,
InputIterator2 pgn_end2,
OutputIterator oi)

Computes the union of the general polygons and general polygons with holes in the given two ranges. A point is contained in the symmetric difference, if and only if it is contained in odd number of input polygons. The result, represented by a set of general poygon with holes, is inserted into an output container through a given output iterator oi. The output iterator is returned. The value type of the OutputIterator is Traits::Polygon_with_holes_2.
