static void getLines (const Geometry &geom, std::vector< const LineString * > &ret)

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  )  [inline]

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


Member Function Documentation

void geos::geom::util::LinearComponentExtracter::filter_rw ( Geometry geom  )  [inline, virtual]

Performs an operation with or on geom.

Parameters:
geom a 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 
) [inline, 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.
