Member Function Documentation

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.

Returns:
a Collection of SegmentStrings representing the raw buffer curves
