Detailed Description

Extracts all the 2-dimensional (Polygon) components from a Geometry.

Constructor & Destructor Documentation

geos::geom::util::PolygonExtracter::PolygonExtracter ( std::vector< const Polygon * > &  newComps)

Constructs a PolygonExtracterFilter with a list in which to store Polygons found.

static void geos::geom::util::PolygonExtracter::getPolygons ( const Geometry geom,
std::vector< const Polygon * > &  ret 
)
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.
