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.
