Method Detail

getFinalChannelHandlers

protected LinkedHashMap<String,Callable<? extends org.jboss.netty.channel.ChannelHandler>> getFinalChannelHandlers(MessageInput input)

Description copied from class: NettyTransport

Subclasses can override this to modify the channel handlers at the end of the pipeline.

The default handlers in this group are the aggregation handler (e.g. for chunked GELF via UDP), which can be missing, and the NettyTransport.RawMessageHandler.

Usually this should not be necessary, only modify them if you have a codec that cannot create a RawMessage for incoming messages at the end of the pipeline.

One valid use case would be to insert debug handlers in the middle of the list, though.

Overrides:

getFinalChannelHandlers in class NettyTransport

Returns:

the list of channel handlers at the end of the pipeline
