| Geometry * geos::geom::LineString::clone | ( | ) | const [inline, virtual] |
Creates and returns a full copy of this LineString object. (including all coordinates contained by it).
Implements geos::geom::Geometry.
Reimplemented in geos::geom::LinearRing.
| void geos::geom::LineString::apply_rw | ( | CoordinateSequenceFilter & | filter | ) | [virtual] |
Performs an operation on the coordinates in this Geometry's CoordinateSequences.s If the filter reports that a coordinate value has been changed, geometryChanged will be called automatically.
| filter | the filter to apply |
Implements geos::geom::Geometry.
| void geos::geom::LineString::apply_ro | ( | CoordinateSequenceFilter & | filter | ) | const [virtual] |
Performs a read-only operation on the coordinates in this Geometry's CoordinateSequences.
| filter | the filter to apply |
Implements geos::geom::Geometry.
| virtual void geos::geom::LineString::normalize | ( | ) | [virtual] |
Normalizes a LineString.
A normalized linestring has the first point which is not equal to it's reflected point less than the reflected point.
Implements geos::geom::Geometry.
| Geometry* geos::geom::LineString::reverse | ( | ) | const |
Creates a LineString whose coordinates are in the reverse order of this objects
Reimplemented in geos::geom::LinearRing.
