Take bus express lines 3, 10, 30, 45, 202, 209, 601 and K1 to get off "Quanshan Road (Qingyuan Mountain Scenic Area)".谁也没有想到，如此灿烂的一战，竟然以这样一种结局收场。就在外边等，如何？不管有没有，在下让胡公子给济世堂赔罪。要说的话他也真算个能将，随机应变，算清这一点后，当即号令：对方没有火绳。可是，当泰德遇到了率领着战斗部队的阿亚纳米参谋长时，他的记忆恢复了。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.
