Detailed Description

Extracts a single point from each connected element in a Geometry (e.g. a polygon, linestring or point) and returns them in a list.

Member Function Documentation

filter_ro()

void geos::operation::distance::ConnectedElementPointFilter::filter_ro ( const geom::Geometry *  geom )

overridevirtual

Reimplemented from geos::geom::GeometryFilter.

getCoordinates()

static std::vector< const geom::CoordinateXY * > * geos::operation::distance::ConnectedElementPointFilter::getCoordinates ( const geom::Geometry *  geom )

static

Returns a list containing a Coordinate from each Polygon, LineString, and Point found inside the specified geometry. Thus, if the specified geometry is not a GeometryCollection, an empty list will be returned.
