This class is functionally equivelent to an OGRLineString, but has a separate identity to maintain alignment with the OpenGIS simple feature data model. It exists to serve as a component of an OGRPolygon.
|
Assign geometry from well known binary data. The object must have already been instantiated as the correct derived type of geometry object to match the binaries type. This method is used by the OGRGeometryFactory class, but not normally called by application code. This method relates to the SFCOM IWks::ImportFromWKB() method. This method is the same as the C function OGR_G_ImportFromWkb().
Reimplemented from OGRLineString. |
|
Returns TRUE if the ring has clockwise winding.
