这是通过客户机调用Grid服务上的订阅操作实现的，告知grid服务它对哪项数据感兴趣以及客户机的通知接收者的位置。

Finally, the Receiver class submits itself as a PostServiceListener so that the post service calls the posted function back when a notification arrives.

最后，receiver类将其自身作为PostServiceListener进行提交，这样，当通知到达时，post服务将回调posted函数。

Then, the Sametime server transfers the notification to the event-receiver agent applet embedded in the Field Service UI.

然后，Sametime 服务器将通知传送到内嵌在 Field Service UI 中的事件接收者代理 applet。
