Class JTSPoints

java.lang.Object
  org.deegree.geometry.standard.points.JTSPoints

All Implemented Interfaces:

com.vividsolutions.jts.geom.CoordinateSequence, Cloneable, Iterable<Point>, Points

public class JTSPoints
extends Object
implements Points

Points implementation based on a JTS coordinate sequence.

This implementation is useful when JTS geometries have to converted into Geometry objects.
