Class LengthLocationMap

Hierarchy: Object , LengthLocationMap

public class LengthLocationMap

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.

public LengthLocationMap(Geometry linearGeom)

public static LinearLocation getLocation(Geometry linearGeom, double length)

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

Parameters:: linearGeom - linearGeom the linear geometry to use; length - length the length index of the location

Returns:: the LinearLocation for the length

public static LinearLocation getLocation(Geometry linearGeom, double length, boolean resolveLower)

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

Parameters:: linearGeom - linearGeom the linear geometry to use; length - length the length index of the location; resolveLower - resolveLower if true lengths are resolved to the lowest possible index

Returns:: the LinearLocation for the length

public static double getLength(Geometry linearGeom, LinearLocation loc)

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

Parameters:: linearGeom - linearGeom the linear geometry to use; loc - loc the LinearLocation index of the location

Returns:: the length for the LinearLocation

public LinearLocation getLocation(double length)

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 - length the length index

Returns:: the corresponding LinearLocation

public LinearLocation getLocation(double length, boolean resolveLower)

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

Parameters:: length - length the length index

Returns:: the corresponding LinearLocation

public double getLength(LinearLocation loc)
