Class TextWebsocketEncoder

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelOutboundHandlerAdapter

io.netty.handler.codec.MessageToMessageEncoder<Event>

io.nadron.handlers.netty.TextWebsocketEncoder

All Implemented Interfaces:

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

@ChannelHandler.Sharable
public class TextWebsocketEncoder
extends io.netty.handler.codec.MessageToMessageEncoder<Event>
