## com.bbn.openmap.omGraphics
Class SinkGraphic

    java.lang.Object
      com.bbn.openmap.omGraphics.geom.BasicGeometry
          com.bbn.openmap.omGraphics.OMGraphic
              com.bbn.openmap.omGraphics.SinkGraphic

All Implemented Interfaces:
  java.lang.Cloneable, OMGeometry, OMGraphicConstants, java.io.Serializable

public class SinkGraphic
extends OMGraphic

This graphic is a Sink. You can use it as a placeholder, say in an OMGraphicList. It is never visible, and you can use the single shared instance in as many places as you want. This shared instance is multithreaded safe.

  `OMGraphic`, Serialized Form
