In particular , this part introduces ws - notification , which enables you to simulate an event - driven application in the stateless environment of web services 這里,我們要介紹ws - notification ,它使我們可以在web服務(wù)的無狀態(tài)環(huán)境中模擬事件驅(qū)動的應(yīng)用程序。
The paper described the definition of the petri - ds . the place simulated the event and the transition simulated the limitation put on the primitive events to make up of the composite event . different composite events have different guard expression 描述了用于檢測復合事件的petri網(wǎng)的定義petri - ds ,其中用點模擬事件,變遷模擬對組成復合事件的成員事件的各種限制,不同的復合事件對應(yīng)的守衛(wèi)表達式不同。
