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.

Member Function Documentation

filter_ro()

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

overridevirtual

Reimplemented from geos::geom::GeometryComponentFilter.

filter_rw()

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

overridevirtual

Performs an operation with or on geom.

Parameters

geom	a Geometry to which the filter is applied.

Reimplemented from geos::geom::GeometryComponentFilter.

getCoordinates()

static 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.
