      com.bbn.openmap.layer.learn.SimpleAnimationLayer.ManageGraphicsTask

All Implemented Interfaces:

java.lang.Runnable

Enclosing class:

SimpleAnimationLayer

public class SimpleAnimationLayer.ManageGraphicsTask
extends java.util.TimerTask

This is a TimerTask the timer uses to tell the points to update their position. This is where you would do work to change the position of your OMGraphics - whether by reading a data file, or checking a web site, whatever. This method could also be the call another object could call with new OMGraphics to display, if you wanted a different object to control the updates.
