Class ChannelHandler

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

io.netty.channel.ChannelDuplexHandler

io.netty.handler.codec.MessageToMessageCodec<cpw.mods.fml.common.network.internal.FMLProxyPacket,Packet>

buildcraft.core.lib.network.ChannelHandler

All Implemented Interfaces:

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

@ChannelHandler.Sharable
public final class ChannelHandler
extends io.netty.handler.codec.MessageToMessageCodec<cpw.mods.fml.common.network.internal.FMLProxyPacket,Packet>

Code based on FMLIndexedMessageToMessageCodec, but since some of its fields are private, I needed a custom version.

testMessageValidity

protected void testMessageValidity(cpw.mods.fml.common.network.internal.FMLProxyPacket msg)

Called to verify the message received. This can be used to hard disconnect in case of an unexpected packet, say due to a weird protocol mismatch. Use with caution.
