static void | getLines (const Geometry &geom, std::vector< const LineString * > &ret) |
Extracts all the 1-dimensional (LineString) components from a Geometry.
geos::geom::util::LinearComponentExtracter::LinearComponentExtracter | ( | std::vector< const LineString * > & | newComps | ) | [inline] |
Constructs a LinearComponentExtracterFilter with a list in which to store LineStrings found.
void geos::geom::util::LinearComponentExtracter::filter_rw | ( | Geometry * | geom | ) | [inline, virtual] |
Performs an operation with or on geom
.
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.
