`SchedulerListeners` 和`TriggerListener`、`JobListener` 一样，接收scheduler本身的事件通知。事件包括：往scheduler中添加`job/trigger` 的时候，移除`job/trigger` 的时候，scheduler出现严重错误的时候，scheduler被shutdown时。

#### The org.quartz.SchedulerListener Interface ####

public interface SchedulerListener {
    
        public void jobScheduled(Trigger trigger);
    
        public void jobUnscheduled(String triggerName, String triggerGroup);
    
        public void triggerFinalized(Trigger trigger);
    
        public void triggersPaused(String triggerName, String triggerGroup);
    
        public void triggersResumed(String triggerName, String triggerGroup);
    
        public void jobsPaused(String jobName, String jobGroup);
    
        public void jobsResumed(String jobName, String jobGroup);
    
        public void schedulerError(String msg, SchedulerException cause);
    
        public void schedulerStarted();
    
        public void schedulerInStandbyMode();
    
        public void schedulerShutdown();
    
        public void schedulingDataCleared();
    }

`SchedulerListeners` 通过scheduler的ListenerManager进行注册，对于实现了`org.quartz.SchedulerListener` 接口的对象是虚拟存在的。

#### Adding a SchedulerListener: ####

scheduler.getListenerManager().addSchedulerListener(mySchedListener);

#### Removing a SchedulerListener: ####

scheduler.getListenerManager().removeSchedulerListener(mySchedListener);
