Detailed Description

Extracts a single representative Coordinate from each connected component of a Geometry.

Version
1.9

Constructor & Destructor Documentation

geos::geom::util::ComponentCoordinateExtracter::ComponentCoordinateExtracter ( std::vector< const Coordinate * > &  newComps)
inline

Constructs a ComponentCoordinateFilter with a list in which to store Coordinates found.

Member Function Documentation

void geos::geom::util::ComponentCoordinateExtracter::filter_rw ( Geometry geom)
inlinevirtual

Performs an operation with or on geom.

Parameters
geoma Geometry to which the filter is applied.

Reimplemented from geos::geom::GeometryComponentFilter.

References geos::geom::GEOS_LINEARRING, geos::geom::GEOS_LINESTRING, geos::geom::GEOS_POINT, geos::geom::Geometry::getCoordinate(), and geos::geom::Geometry::getGeometryTypeId().

static void geos::geom::util::ComponentCoordinateExtracter::getCoordinates ( const Geometry geom,
std::vector< const Coordinate * > &  ret 
)
inlinestatic

Push the linear 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 ComponentCoordinateFilter instance and pass it to multiple geometries.
