Class LengthLocationMap

java.lang.Object
  com.vividsolutions.jts.linearref.LengthLocationMap

public class LengthLocationMap
extends java.lang.Object

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.

Constructor Summary

Method Detail

getLocation

public static LinearLocation getLocation(Geometry linearGeom,
                                         double length)

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

getLength

public static double getLength(Geometry linearGeom,
                               LinearLocation loc)

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

getLocation

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.

Parameters:

length - the length index

Returns:

the corresponding LinearLocation

getLength

public double getLength(LinearLocation loc)
