## Detailed Description

Extracts the subline of a linear Geometry between two LinearLocations on the line.

## Member Function Documentation

static geom::Geometry* geos::linearref::ExtractLineByLocation::extract | ( | const geom::Geometry * | line,
|  | const LinearLocation & | start,
|  | const LinearLocation & | end
| ) |  | `[static]`

Computes the subline of a LineString between two LineStringLocations on the line. If the start location is after the end location, the computed geometry is reversed.

Parameters:

  line | the line to use as the baseline
  start | the start location
  end | the end location

Returns:
  the extracted subline

geom::Geometry* geos::linearref::ExtractLineByLocation::extract | ( | const LinearLocation & | start,
|  | const LinearLocation & | end
| ) |  |

Extracts a subline of the input. If `end < start` the linear geometry computed will be reversed.

Parameters:

  start | the start location
  end | the end location

Returns:
  a linear geometry
