Class Http2ClientStreamFrameResponseHandler

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

io.netty.channel.SimpleChannelInboundHandler<io.netty.handler.codec.http2.Http2StreamFrame>

io.netty.example.http2.helloworld.frame.client.Http2ClientStreamFrameResponseHandler

All Implemented Interfaces:

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

public final class Http2ClientStreamFrameResponseHandler
extends io.netty.channel.SimpleChannelInboundHandler<io.netty.handler.codec.http2.Http2StreamFrame>

Handles HTTP/2 stream frame responses. This is a useful approach if you specifically want to check the main HTTP/2 response DATA/HEADERs, but in this example it's used purely to see whether our request (for a specific stream id) has had a final response (for that same stream id).
