The internal representation of a list of coordinates inside a Geometry.
Definition: CoordinateSequence.h:58
Represents a list of contiguous line segments, and supports noding the segments.
Definition: BasicSegmentString.h:44
BasicSegmentString(geom::CoordinateSequence *newPts, const void *newContext)
Construct a BasicSegmentString.
Definition: BasicSegmentString.h:53
geom::CoordinateSequence * getCoordinates() const override
int getSegmentOctant(size_t index) const
Gets the octant of the segment starting at vertex index.
An interface for classes which represent a sequence of contiguous line segments.
Definition: SegmentString.h:46
Basic namespace for all GEOS functionalities.
