Class ClientWebSocketExternalCodec

java.lang.Object
io.netty.channel.ChannelHandlerAdapter
io.netty.channel.ChannelInboundHandlerAdapter
io.netty.channel.ChannelDuplexHandler
io.netty.handler.codec.MessageToMessageCodec<io.netty.handler.codec.http.websocketx.BinaryWebSocketFrame, ExternalMessage>
com.iohao.net.extension.client.join.ClientWebSocketExternalCodec
All Implemented Interfaces:
io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler, io.netty.channel.ChannelOutboundHandler
public class ClientWebSocketExternalCodec extends io.netty.handler.codec.MessageToMessageCodec<io.netty.handler.codec.http.websocketx.BinaryWebSocketFrame, ExternalMessage>
Client codec that converts between BinaryWebSocketFrame and ExternalMessage.

Mirrors the server-side WebSocketExternalCodec: raw DataCodecManager bytes are carried directly inside a binary WebSocket frame, without any length prefix, since WebSocket framing already preserves message boundaries.
