SimpleTrigger的属性包括：开始时间、结束时间、重复次数以及重复的间隔   
CronTrigger是基于日历表示法的调度，而不是基于指定间隔的简单调度

listener是一个对象，用于监听scheduler中发生的事件，然后执行相应的操作，TriggerListeners接受与trigger相关的事件，JobListeners接受与jobs相关的事件。
trigger相关的事件包括：trigger的触发、trigger错过触发(mis-fire)以及trigger的完成(即trigger触发的job执行完成)。
job相关的事件包括：job即将执行的通知以及job执行完毕的通知。

SchedulerListener与TriggerListener、JobListener类似，但它仅接收来自Scheduler自身的消息，而不一定是某个具体的trigger或job的消息。

scheduler相关的消息包括：job/trigger的增加、job/trigger的删除、scheduler内部发生的严重错误以及scheduler关闭的消息等；
