Detailed Description

Extracts all the 1-dimensional (LineString) components from a Geometry.

Constructor & Destructor Documentation

LinearComponentExtracter()

geos::geom::util::LinearComponentExtracter::LinearComponentExtracter

(

std::vector< const LineString * > &

newComps

)

Constructs a LinearComponentExtracterFilter with a list in which to store LineStrings found.

Member Function Documentation

filter_ro()

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

overridevirtual

Reimplemented from geos::geom::GeometryComponentFilter.

filter_rw()

void geos::geom::util::LinearComponentExtracter::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.

getLines()

static void geos::geom::util::LinearComponentExtracter::getLines ( const Geometry &  geom, std::vector< const LineString * > &  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 LinearComponentExtracterFilter instance and pass it to multiple geometries.
