  public LengthLocationMap(Geometry linearGeom)

Method Detail

• getLocation

  public static LinearLocation getLocation(Geometry linearGeom,
                                           double length)

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

  Parameters:

  linearGeom - the linear geometry to use

  length - the length index of the location

  Returns:

  the LinearLocation for the length

• getLocation

  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 - 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

• getLength

  public static double getLength(Geometry linearGeom,
                                 LinearLocation loc)

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

  Parameters:

  linearGeom - 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. Ambiguous indexes are resolved to the lowest possible location value.

  Parameters:

  length - the length index

  Returns:

  the corresponding LinearLocation

• getLocation

  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 - the length index

  Returns:

  the corresponding LinearLocation

• getLength

  public double getLength(LinearLocation loc)
