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 CoordinateXY * > & 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)
overridevirtual

◆ filter_rw()

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

Performs an operation with or on geom.

Parameters
geoma 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 CoordinateXY * > & 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.
