channelRead

protected abstract void channelRead(io.netty.channel.ChannelHandlerContext ctx,
                                    Http3HeadersFrame frame)
                             throws Exception

Called once a Http3HeadersFrame is ready for this stream to process.

Parameters:

ctx - the ChannelHandlerContext of this handler.

frame - the Http3HeadersFrame that was read

Throws:

Exception - thrown if an error happens during processing.

channelRead

protected abstract void channelRead(io.netty.channel.ChannelHandlerContext ctx,
                                    Http3DataFrame frame)
                             throws Exception

Called once a Http3DataFrame is ready for this stream to process.

Parameters:

ctx - the ChannelHandlerContext of this handler.

frame - the Http3DataFrame that was read

Throws:

Exception - thrown if an error happens during processing.

channelInputClosed

protected abstract void channelInputClosed(io.netty.channel.ChannelHandlerContext ctx)
                                    throws Exception

Called once the input is closed and so no more inbound data is received on it.

Parameters:

ctx - the ChannelHandlerContext of this handler.

Throws:

Exception - thrown if an error happens during processing.

channelRead

protected void channelRead(io.netty.channel.ChannelHandlerContext ctx,
                           Http3UnknownFrame frame)

Called once a Http3UnknownFrame is ready for this stream to process. By default these frames are just released and so dropped on the floor as stated in the RFC. That said you may want to override this method if you use some custom frames which are not part of the main spec.

Parameters:

ctx - the ChannelHandlerContext of this handler.

frame - the Http3UnknownFrame that was read

handleQuicException

protected void handleQuicException(io.netty.channel.ChannelHandlerContext ctx,
                                   io.netty.incubator.codec.quic.QuicException exception)

Called once a QuicException should be handled.

Parameters:

ctx - the ChannelHandlerContext of this handler.

exception - the QuicException that caused the error.

handleHttp3Exception

protected void handleHttp3Exception(io.netty.channel.ChannelHandlerContext ctx,
                                    Http3Exception exception)

Called once a Http3Exception should be handled.

Parameters:

ctx - the ChannelHandlerContext of this handler.

exception - the Http3Exception that caused the error.

controlStream

@Nullable
protected final @Nullable io.netty.incubator.codec.quic.QuicStreamChannel controlStream(io.netty.channel.ChannelHandlerContext ctx)

Return the local control stream for this HTTP/3 connection. This can be used to send Http3ControlStreamFrames to the remote peer.

Parameters:

ctx - the ChannelHandlerContext of this handler.

Returns:

the control stream.
