Detailed Description

Computes the LinearLocation for a given length along a linear Geometry. Negative lengths are measured in reverse from end of the linear geometry. Out-of-range values are clamped.

static LinearLocation geos::linearref::LengthLocationMap::getLocation ( const geom::Geometry linearGeom,
double  length,
bool  resolveLower 
)
inlinestatic

Returns
the LinearLocation for the length

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. Out-of-range values are clamped. Ambiguous indexes are resolved to the lowest possible location value, depending on the value of resolveLower.

Parameters
lengththe length index
Returns
the corresponding LinearLocation
LinearLocation geos::linearref::LengthLocationMap::getLocation ( double  length) const

Compute the LinearLocation corresponding to a length.

Negative lengths are measured in reverse from end of the linear geometry. Out-of-range values are clamped. Ambiguous indexes are resolved to the lowest possible location value.

Parameters
lengththe length index
Returns
the corresponding LinearLocation
