一个 TimerEventSubscriptionCollection,表示与工作流实例关联的 TimerEventSubscription 对象的队列,并提供管理此队列的方法。A TimerEventSubscriptionCollection represents the queue of TimerEventSubscription objects associated with a workflow instance and provides methods to manage this queue. 订阅在队列中的排序方式基于其 ExpiresAt 值;具有较小 ExpiresAt 值的订阅将放置在具有较大 ExpiresAt 值的订阅的前面。Subscriptions are ordered in the queue based on their ExpiresAt values; those with smaller ExpiresAt values are positioned before those with larger ExpiresAt values. 您可以使用此类提供的方法,管理各个工作流实例的 TimerCollectionProperty 公开的活动计时器事件订阅的集合。You can use the methods provided by this class to manage the collection of active timer event subscriptions exposed by TimerCollectionProperty for each workflow instance. 您可以使用 AddRemove 添加或移除计时器队列中的订阅。You can use Add or Remove to add or remove subscriptions from the timer queue. 只要计时器队列中的第一个元素更改,就会调用 WorkflowSchedulerService 来取消先前位于队列开头的计时器事件,并计划新的计时器事件。Whenever the first element in the timer queue changes, the WorkflowSchedulerService is called to cancel the timer event that was previously at the beginning of the queue and schedule the new timer event.
