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.

Member Function Documentation

static double geos::linearref::LengthLocationMap::getLength	(	const geom::Geometry *	linearGeom,
		const LinearLocation &	loc
	)			[static]

Computes the length for a given LinearLocation on a linear Geometry.

Parameters:

	line	the linear geometry to use
	loc	the LinearLocation index of the location

Returns:

the length for the 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:

length

the length index

Returns:

the corresponding LinearLocation

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:

length

the length index

Returns:

the corresponding LinearLocation

static LinearLocation geos::linearref::LengthLocationMap::getLocation	(	const geom::Geometry *	linearGeom,
		double	length,
		bool	resolveLower
	)			[inline, static]

Computes the LinearLocation for a given length along a linear Geometry.

Parameters:

	line	the linear geometry to use
	length	the length index of the location
	resolveLower	if true lengths are resolved to the lowest possible index

Returns:

the LinearLocation for the length

static LinearLocation geos::linearref::LengthLocationMap::getLocation	(	const geom::Geometry *	linearGeom,
		double	length
	)			[inline, static]

Computes the LinearLocation for a given length along a linear Geometry.

Parameters:

	line	the linear geometry to use
	length	the length index of the location

Returns:

the LinearLocation for the length
