void apply_ro(CoordinateSequenceFilter &filter) const override
virtual std::unique_ptr< Point > getStartPoint() const
Return the start point of the LineString or NULL if this is an EMPTY LineString.
std::unique_ptr< Geometry > getBoundary() const override
Returns a MultiPoint. Empty for closed LineString, a Point for each vertex otherwise.
LineString(CoordinateSequence *pts, const GeometryFactory *newFactory)
Constructs a LineString taking ownership the given CoordinateSequence.
void normalize() override
Normalizes a LineString.
std::unique_ptr< CoordinateSequence > getCoordinates() const override
Returns this Geometry vertices. Caller takes ownership of the returned object.
const Coordinate * getCoordinate() const override
Returns a vertex of this Geometry, or NULL if this is the empty geometry.
bool isEmpty() const override
Returns whether or not the set of points in this Geometry is empty.
std::unique_ptr< Geometry > reverse() const override
Dimension::DimensionType getDimension() const override
Returns line dimension (1)
GeometryTypeId getGeometryTypeId() const override
Return an integer representation of this Geometry type.
virtual std::unique_ptr< Point > getEndPoint() const
Return the end point of the LineString or NULL if this is an EMPTY LineString.
std::vector< const LineString * > ConstVect
A vector of const LineString pointers.

void apply_rw(CoordinateSequenceFilter &filter) override
LineString(CoordinateSequence::Ptr &&pts, const GeometryFactory &newFactory)
Hopefully cleaner version of the above.
double getLength() const override
Returns the length of this Geometry.
int getBoundaryDimension() const override
Returns Dimension::False for a closed LineString, 0 otherwise (LineString boundary is a MultiPoint)
std::string getGeometryType() const override
Return a string representation of this Geometry type.
bool equalsExact(const Geometry *other, double tolerance=0) const override
