Class GeometryNoder

generative/include/generative/noding/geometry-noder.h:25–53

@brief Nodes a geometry using the specified geos::noding::Noder. @note The process of "noding" a geometry is finding all pairs intersections, and breaking the geometry into a sequence of non-intersecting (except at the endpoints) geos::noding::SegmentString's. @details The implementation of generative::noding::GeometryNoder is the same as geos::noding::GeometryNoder, with the sole exception that y
