Detailed Description

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

Version: 1.9

Constructor & Destructor Documentation

◆ ComponentCoordinateExtracter()

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

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

Referenced by filter_rw().

Member Function Documentation

◆ filter_ro()

void geos::geom::util::ComponentCoordinateExtracter::filter_ro ( const Geometry * geom )

virtual

Reimplemented from geos::geom::GeometryComponentFilter.

◆ filter_rw()

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

virtual

Performs an operation with or on geom.

Parameters

geom	a `Geometry` to which the filter is applied.

Reimplemented from geos::geom::GeometryComponentFilter.

References ComponentCoordinateExtracter().

◆ getCoordinates()

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

static

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.
