Extracts a single representative Coordinate from each connected component of a Geometry.
geos::geom::util::ComponentCoordinateExtracter::ComponentCoordinateExtracter | ( | std::vector< const Coordinate * > & | newComps | ) | [inline] |
Constructs a ComponentCoordinateFilter with a list in which to store Coordinates found.
void geos::geom::util::ComponentCoordinateExtracter::filter_rw | ( | Geometry * | geom | ) | [inline, virtual] |
Performs an operation with or on geom
.
geom | a Geometry to which the filter is applied. |
Reimplemented from geos::geom::GeometryComponentFilter.

Push the linear components from a single geometry into the provided vector. If more than one geometry is to be processed, it is more efficient to create a single ComponentCoordinateFilter instance and pass it to multiple geometries.
