geos::operation::distance::ConnectedElementLocationFilter Class Reference

A ConnectedElementPointFilter extracts a single point from each connected element in a Geometry (e.g. a polygon, linestring or point) and returns them in a list. The elements of the list are DistanceOp::GeometryLocation. More...

Detailed Description

A ConnectedElementPointFilter extracts a single point from each connected element in a Geometry (e.g. a polygon, linestring or point) and returns them in a list. The elements of the list are DistanceOp::GeometryLocation.

Member Function Documentation

filter_ro()

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

virtual

Reimplemented from geos::geom::GeometryFilter.

filter_rw()

void geos::operation::distance::ConnectedElementLocationFilter::filter_rw ( geom::Geometry * geom )

virtual

Reimplemented from geos::geom::GeometryFilter.

getLocations()

std::vector< GeometryLocation * > * geos::operation::distance::ConnectedElementLocationFilter::getLocations ( const geom::Geometry * geom )

static

Returns a list containing a point 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. The elements of the list are com.vividsolutions.jts.operation.distance.GeometryLocations.
