Method Summary

Modifier and Type	Method and Description
GeometryOperation<Double>	createGetMeasureOp(Geometry geometry, Point point) Creates a GeometryOperation to calculate the measure value at the specified point
GeometryOperation<Double>	createGetMeasureOp(Geometry geometry, Point point, double tolerance) Creates a GeometryOperation to calculate the measure value, given that the points fall within a specified distance from the linestring at the specified point
GeometryOperation<Geometry>	createMeasureOnLengthOp(Geometry geometry, boolean keepBeginMeasure) Creates a GeometryOperation that creates a new Geometry that has the same 2D/3D-coordinates as the specified Geometry, and with measure values that correspond with the length along it (or begin-measure + length).

Method Detail

createGetMeasureOp

GeometryOperation<Double> createGetMeasureOp(Geometry geometry,
                                             Point point)

Creates a GeometryOperation to calculate the measure value at the specified point

Parameters:

geometry - a measured Geometry

point - a Point on the geometry

Returns:

a GeometryOperation that returns the measure value at the specified point on the specified geometry

createGetMeasureOp

GeometryOperation<Double> createGetMeasureOp(Geometry geometry,
                                             Point point,
                                             double tolerance)

Creates a GeometryOperation to calculate the measure value, given that the points fall within a specified distance from the linestring at the specified point

Parameters:

geometry - a measured Geometry

point - a Point on the geometry

tolerance - the maximum allowed distance between geometry and point

Returns:

a GeometryOperation that returns the measure value at the specified point on the specified geometry

Throws:

IllegalArgumentException - when point is not within tolerance of geometry

createMeasureOnLengthOp

GeometryOperation<Geometry> createMeasureOnLengthOp(Geometry geometry,
                                                    boolean keepBeginMeasure)

Creates a GeometryOperation that creates a new Geometry that has the same 2D/3D-coordinates as the specified Geometry, and with measure values that correspond with the length along it (or begin-measure + length).

The length is calculated in the 2-dimensional X/Y-plane.

Parameters:

geometry - the Geometry for which to build measures

keepBeginMeasure - if true, than the measure of the first coordinate is used as start-value

Returns:

a GeometryOperation that returns a Geometry with measures increasing with length
