Creates all the raw offset curves for a buffer of a Geometry.
Raw curves need to be noded together and polygonized to form the final buffer area.
| void geos::operation::buffer::OffsetCurveSetBuilder::addCurves | ( | const std::vector< geom::CoordinateSequence * > & | lineList, |
| int | leftLoc, | ||
| int | rightLoc | ||
| ) |
Add raw curves for a set of CoordinateSequences.
| lineList | is a list of CoordinateSequence, ownership of which is transferred here. |
| std::vector<noding::SegmentString*>& geos::operation::buffer::OffsetCurveSetBuilder::getCurves | ( | ) |
Computes the set of raw offset curves for the buffer.
Each offset curve has an attached geomgraph::Label indicating its left and right location.
