For example, in Java, the Selector's select () method is used to implement this synchronous blocking operation waiting for an event to occur. In the implementation of select () under Linux operating system, a) will call epollCtl (epfd, opcode, fd, events) to register the events that have been registered in Initiation Dispatcher into Linux system, where fd means Handle and events means Handle events that we are interested in; B) Synchronize the occurrence of a blocked wait registered event by calling the epollWait method. Events on different event sources may occur at the same time. Once an event is triggered, the epollWait method will return. C) Finally, find the associated SelectorKeyImpl object by the event that occurred, set the event that occurred to the ready state, and then put the SelectorKeyImpl into the selectedSet. In this way, we can get the event-ready SelectorKeyImpl collection through the Selector.selectedKeys () method.几个姐妹正在小屋内享受假期时却遭到了几个戴着面具的闯入者的袭击，她们必须奋力一战才能活过这一夜。“明知所作为孽，但以爱为借口”　　腊月二十三耕田和秀兰在集市买年货却碰上警察抓了同乡村民六子的孩子丑娃，耕田代管了丑娃，可丑娃恶习不改偷了村里玲爱家铁蛋的长命锁，闹得玲爱怀疑起了耕田。
