Class ChartScheduler

java.lang.Object
  net.commerce.zocalo.freechart.ChartScheduler

public class ChartScheduler
extends java.lang.Object

Schedule a task like generating a price history graph. Multiple requests may come in sporadically. We want to ensure that only one is being processed at a time. If we're busy processing when a request comes in, we'll remember to start another when this one is done. Multiple requests that come in while processing will spur a single restart.
