Syntax

public class LengthLocationMap

Constructors

LengthLocationMap(Geometry)

Initializes a new instance of the LengthLocationMap class.

Declaration

public LengthLocationMap(Geometry linearGeom)

Parameters

Type	Name	Description
Geometry	linearGeom	A linear geometry.

Methods

GetLength(Geometry, LinearLocation)

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

Declaration

public static double GetLength(Geometry linearGeom, LinearLocation loc)

Parameters

Type	Name	Description
Geometry	linearGeom	The linear geometry to use.
LinearLocation	loc	The LinearLocation index of the location.

Returns

Type	Description
double	The length for the LinearLocation.

GetLength(LinearLocation)

Declaration

public double GetLength(LinearLocation loc)

Parameters

Type	Name	Description
LinearLocation	loc

Returns

Type	Description
double

GetLocation(Geometry, double)

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

Declaration

public static LinearLocation GetLocation(Geometry linearGeom, double length)

Parameters

Type	Name	Description
Geometry	linearGeom	The linear geometry to use.
double	length	The length index of the location.

Returns

Type	Description
LinearLocation	The LinearLocation for the length.

GetLocation(Geometry, double, bool)

Computes the LinearLocation for a given length along a linear Geometry, with control over how the location is resolved at component endpoints.

Declaration

public static LinearLocation GetLocation(Geometry linearGeom, double length, bool resolveLower)

Parameters

Type	Name	Description
Geometry	linearGeom	The linear geometry to use
double	length	The length index of the location
bool	resolveLower	If true lengths are resolved to the lowest possible index

Returns

Type	Description
LinearLocation

GetLocation(double)

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.

Declaration

public LinearLocation GetLocation(double length)

Parameters

Type	Name	Description
double	length	The length index.

Returns

Type	Description
LinearLocation	The corresponding LinearLocation.

GetLocation(double, bool)

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 or highest possible location value, depending on the value of resolveLower

Declaration

public LinearLocation GetLocation(double length, bool resolveLower)

Parameters

Type	Name	Description
double	length	The length index
bool	resolveLower

Returns

Type	Description
LinearLocation	The corresponding LinearLocation.
