Method Details

accept

void accept(io.netty.channel.ChannelHandlerContext ctx,
 io.netty.handler.codec.http.HttpRequest request,
 PipeliningServerHandler.OutboundAccess outboundAccess)

Handle a request.

Parameters:

ctx - The context this request came in on

request - The request, either a FullHttpRequest or a StreamedHttpRequest

outboundAccess - The PipeliningServerHandler.OutboundAccess to use for writing the response

handleUnboundError

void handleUnboundError(Throwable cause)

Handle an error that is not bound to a request, i.e. happens outside of a StreamedHttpRequest.

Parameters:

cause - The error

responseWritten

default void responseWritten(Object attachment)

Called roughly when a response has been written. In particular, it's called when the user is "done" with the response and has no way of adding further data. The bytes may not have been fully flushed yet, but e.g. the response Publisher has been fully consumed.
This is used for cleaning up the request.

Parameters:

attachment - Object passed to PipeliningServerHandler.OutboundAccess.attachment(Object)

removed

default void removed()

Called when the handler is removed.
