All Implemented Interfaces:

io.netty.channel.ChannelHandler, io.netty.channel.ChannelOutboundHandler

public class WebSocketServerMessageHandler
extends io.netty.channel.ChannelOutboundHandlerAdapter

Encodes WebSocketServerMessageHandler.InternalServerMessage to either BinaryWebSocketFrame or TextWebSocketFrame depending if the protobuf or json has to be sent.
