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...

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.
