Class AbstractNettyIOClient.ByteToMessageDecoder<T>

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

io.netty.handler.codec.ByteToMessageDecoder

org.openremote.agent.protocol.io.AbstractNettyIOClient.ByteToMessageDecoder<T>

All Implemented Interfaces:

io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler

Enclosing class:

AbstractNettyIOClient<T,U extends SocketAddress>

public static class AbstractNettyIOClient.ByteToMessageDecoder<T>
extends io.netty.handler.codec.ByteToMessageDecoder

This is intended to be used at the end of a decoder chain where the previous decoder outputs a ByteBuf; the provided decoder should extract the messages of type <T> from the ByteBuf and add them to the List and they will then be passed to the IOClient.
