static std::unique_ptr<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 LinearLocations on the line.

If the start location is after the end location, the computed geometry is reversed.

Parameters
linethe line to use as the baseline
startthe start location
endthe end location
Returns
the extracted subline

std::unique_ptr<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
startthe start location
endthe end location
Returns
a linear geometry
