## 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.
