Package org.locationtech.jtstest.geomop

Class TeeGeometryOperation

java.lang.Object

org.locationtech.jtstest.geomop.TeeGeometryOperation

All Implemented Interfaces:

GeometryOperation

Direct Known Subclasses:

PreparedGeometryTeeOperation

public abstract class TeeGeometryOperation
extends Object
implements GeometryOperation

A GeometryOperation which executes the original operation and returns that result, but also executes a separate operation (which could be multiple operations). The side operations can throw exceptions if they do not compute correct results. This relies on the availability of another reliable implementation to provide the expected result.

This class can be used via the -geomop command-line option or by the <geometryOperation> XML test file setting.
