Detailed Description

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

Constructor & Destructor Documentation

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

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

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.
