Member Function Documentation

void geos::geom::util::PolygonExtracter::filter_ro ( const Geometry *  geom )

overridevirtual

Reimplemented from geos::geom::GeometryFilter.

void geos::geom::util::PolygonExtracter::filter_rw ( Geometry *  geom )

overridevirtual

Reimplemented from geos::geom::GeometryFilter.

static

Pushes the Polygon 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 PolygonExtracterFilter instance and pass it to multiple geometries.
