Class Http2StreamFrameToHttpObjectCodec

java.lang.Object

io.netty5.channel.ChannelHandlerAdapter

io.netty5.handler.codec.MessageToMessageCodec<Http2StreamFrame,io.netty5.handler.codec.http.HttpObject>

io.netty5.handler.codec.http2.Http2StreamFrameToHttpObjectCodec

All Implemented Interfaces:

io.netty5.channel.ChannelHandler

@UnstableApi
public class Http2StreamFrameToHttpObjectCodec
extends io.netty5.handler.codec.MessageToMessageCodec<Http2StreamFrame,io.netty5.handler.codec.http.HttpObject>

This handler converts from Http2StreamFrame to HttpObject, and back. It can be used as an adapter in conjunction with Http2MultiplexHandler to make http/2 connections backward-compatible with ChannelHandlers expecting HttpObject For simplicity, it converts to chunked encoding unless the entire stream is a single header.
