The policy mode is the packaging of the algorithm, which separates the responsibility of using the algorithm from the algorithm itself and delegates it to different objects. Policy patterns usually wrap a series of algorithms into a series of policy classes. To encapsulate the policy pattern in one sentence is to "encapsulate each algorithm into a different policy class so that they can be interchanged". The following is the structure diagram of the policy mode:
Initiation Dispatcher: This is actually the Reactor role. It defines some specifications, which are used to control the scheduling mode of events, and at the same time provide facilities for applications to register and delete event handlers. It itself is the core of the entire event handler, and Initiation Dispatcher waits for events to occur through Synchronous Event Demultiplexer. Once an event occurs, the Initiation Dispatcher first separates each event, then calls the event handler, and finally calls the relevant callback method to handle these events. Each callback method in Netty's ChannelHandler is called by an EventLoop in BossGroup or WorkGroup.
