@Sharable public class Http2StreamFrameToHttpObjectCodec extends MessageToMessageCodec<Http2StreamFrame,HttpObject>
This handler converts fromHttp2StreamFrame
toHttpObject
, and back. It can be used as an adapter in conjunction withHttp2MultiplexCodec
to make http/2 connections backward-compatible withChannelHandler
s expectingHttpObject
For simplicity, it converts to chunked encoding unless the entire stream is a single header.
