static double  getLength (const geom::Geometry *linearGeom, const LinearLocation &loc) 
Computes the LinearLocation for a given length along a linear Geometry. Negative lengths are measured in reverse from end of the linear geometry. Outofrange values are clamped.

LinearLocation geos::linearref::LengthLocationMap::getLocation  (  double  length, 
bool  resolveLower  
)  const 
Compute the LinearLocation corresponding to a length.
Negative lengths are measured in reverse from end of the linear geometry. Outofrange values are clamped. Ambiguous indexes are resolved to the lowest possible location value, depending on the value of resolveLower
.
length  the length index

Compute the LinearLocation corresponding to a length.
Negative lengths are measured in reverse from end of the linear geometry. Outofrange values are clamped. Ambiguous indexes are resolved to the lowest possible location value.
