java.lang.Object
io.netty.channel.ChannelHandlerAdapter
io.netty.channel.ChannelInboundHandlerAdapter
io.netty.channel.SimpleChannelInboundHandler<io.netty.handler.codec.http.FullHttpRequest>
com.linkedin.venice.listener.RouterRequestHttpHandler
All Implemented Interfaces:
io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler
public class RouterRequestHttpHandler extends io.netty.channel.SimpleChannelInboundHandler<io.netty.handler.codec.http.FullHttpRequest>
Monitors the stream, when it gets enough bytes that form a genuine object, it deserializes the object and passes it along the stack. SimpleChannelInboundHandler.channelRead(ChannelHandlerContext, Object) will release the incoming request object: FullHttpRequest for each request. The downstream handler is not expected to use this object any more.
