static void getLines(const Geometry &geom, std::vector< const LineString *> &ret)
std::vector< const LineString * > ConstVect
A vector of const LineString pointers.
Definition: LineString.h:73
Represents a list of contiguous line segments, and supports noding the segments.
Definition: NodedSegmentString.h:59
Basic implementation of Geometry, constructed and destructed by GeometryFactory.

std::unique_ptr< CoordinateSequence > getCoordinates() const override
Returns this Geometry vertices. Caller takes ownership of the returned object.
static void extractSegmentStrings(const geom::Geometry *g, SegmentString::ConstVect &segStr)
Extracts all linear components from a given Geometry to SegmentStrings.
Definition: SegmentStringUtil.h:50
