## com.vividsolutions.jts.operation.overlay.validate
Class OffsetPointGenerator

    java.lang.Object
      com.vividsolutions.jts.operation.overlay.validate.OffsetPointGenerator

    public class OffsetPointGenerator

extends java.lang.Object

Generates points offset by a given distance from both sides of the midpoint of all segments in a `Geometry`. Can be used to generate probe points for determining whether a polygonal overlay result is incorrect. The input geometry may have any orientation for its rings, but `setSidesToGenerate(boolean, boolean)` is only meaningful if the orientation is known.
