Package org.locationtech.jtstest.geomop

Class BufferValidatedGeometryOperation

java.lang.Object

org.locationtech.jtstest.geomop.BufferValidatedGeometryOperation

All Implemented Interfaces:

GeometryOperation

public class BufferValidatedGeometryOperation
extends java.lang.Object
implements GeometryOperation

A GeometryOperation which validates the results of the Geometry buffer() method. If an invalid result is found, an exception is thrown (this is the most convenient and noticeable way of flagging the problem when using the TestRunner). All other Geometry methods are executed normally.

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