Metricsfacade in turn calls the corresponding singleton collection class to get the kpi Metricsfacade隨后便調(diào)用相應(yīng)的單例集合類(lèi)來(lái)獲得kpi 。
Create the throughput , outcome , and numberofinvalidorders metrics using the appropriate events and add them to the corresponding singleton collection classes ) ,利用合適的事件創(chuàng)建throughput 、 outcome和numberofinvalidorders度量,并將它們加入到相應(yīng)的單例集合類(lèi)中。
The collection classes are singleton classes , which are populated by the ejbs using the events retrieved from the event server and are later accessed by the front end through a session facade to display the kpis 集合類(lèi)是單例類(lèi),并利用事件服務(wù)器上所獲得的事件由ejb進(jìn)行填充,且由前端通過(guò)會(huì)話外觀顯示kpi來(lái)進(jìn)行訪問(wèn)。
