TransportFrameDecoder

class TransportFrameDecoder extends ChannelInboundHandlerAdapter

A customized frame decoder that allows intercepting raw data.

This behaves like Netty's frame decoder (with hard coded parameters that match this library's needs), except it allows an interceptor to be installed to read data directly before it's framed.

Unlike Netty's frame decoder, each frame is dispatched to child handlers as soon as it's decoded, instead of building as many frames as the current buffer allows and dispatching all of them. This allows a child handler to install an interceptor if needed.

If an interceptor is installed, framing stops, and data is instead fed directly to the interceptor. When the interceptor indicates that it doesn't need to read any more data, framing resumes. Interceptors should not hold references to the data buffers provided to their handle() method.
