WebSocketServerHandler is a class in the Java programming language that extends the SimpleChannelInboundHandler class. It is used to handle WebSocket requests and responses in server-side applications.
WebSocket is a protocol that enables real-time communication between a client and a server. It allows bidirectional communication between the two parties, which means that both the client and the server can send and receive messages.
WebSocketServerHandler is responsible for handling the WebSocket handshake, which is the initial exchange of messages between the client and the server that establishes the WebSocket connection. Once the connection is established, the handler can receive and send messages using the WebSocket protocol.
The WebSocketServerHandler class provides several methods that can be overridden to handle different events during the WebSocket communication. For example, the channelRead0() method is called when a message is received from the client, while the channelActive() method is called when the WebSocket connection is established.
Overall, the WebSocketServerHandler class is a crucial component of any WebSocket server application, as it provides the necessary functionality to communicate with clients using the WebSocket protocol.
