Class StretchedVertex

java.lang.Object

org.locationtech.jtstest.testbuilder.topostretch.StretchedVertex

public class StretchedVertex
extends Object

Models a vertex of a Geometry which will be stretched due to being too near other segments and vertices.

Currently for simplicity a vertex is assumed to be near only one segment or other vertex. This is sufficient for most cases.
