Class HttpServerCodecResponsePairing

java.lang.Object
org.mockserver.netty.unification.HttpServerCodecResponsePairing
public final class HttpServerCodecResponsePairing extends Object
Keeps HttpServerCodec pairing each response with the request it answers when an exchange ends without its response passing the codec's encoder. The codec queues each request's method as it decodes the request and takes the oldest off as it encodes a final response, which it encodes for that method (no body for HEAD). A response written as raw bytes beneath the codec (ResponseWrittenBeneathCodecEvent), no response, or a final 1xx (HttpExchangeEndedEvent.INSTANCE) takes none off, so every later response would be encoded for the method of the request before its own.

The codec is final and its queue private, so on each of those events the handler after the codec has it encode an empty response of its own, which takes the entry off, and the handler before the codec writes an empty buffer in place of what the encoder wrote, with the same promise: nothing reaches the client, and a close the codec chains on that write still follows what came before.

    Modifier and Type
    Method
    Description
    io.netty.channel.ChannelHandler
    afterCodec()
    The handler to add immediately after the HTTP server codec.
    io.netty.channel.ChannelHandler
    beforeCodec()
    The handler to add immediately before the HTTP server codec.
    static io.netty.channel.ChannelHandlerContext
    beneathCodec(io.netty.channel.ChannelPipeline pipeline)
    Where to add a handler that must see what is written from beneath the codec, raw bytes and encoded responses alike, but not the stand-in responses: before this pairing's handler before the codec, or the codec if it has none.
    static void
    removeFrom(io.netty.channel.ChannelPipeline pipeline)
    Removes both handlers, if present, for when the connection stops carrying HTTP/1.1 (a CONNECT or SOCKS tunnel).
