Class Point2Ds

  • java.lang.Object
    • com.supermap.data.Point2Ds

  • public class Point2Ds
extends java.lang.Object
    The Point2Ds calss.

    A Point2Ds object is a collection of Point2D objects. The Point2Ds class is used to manage all the vertices on a GeoLine or a part of a GeoLine object. As any GeoLine object or any part of a GeoLine object has direction, so the Point2Ds object is a collection of ordered Point2D objects.
