All Implemented Interfaces:

ChannelHandler, ChannelInboundHandler

public abstract class Http3PushStreamClientInitializer
extends ChannelInitializer<QuicStreamChannel>

Abstract base class that users can extend to init HTTP/3 push-streams for clients. This initializer will automatically add HTTP/3 codecs etc to the ChannelPipeline as well.

Method Details

initChannel

protected final void initChannel(QuicStreamChannel ch)

Description copied from class: ChannelInitializer

This method will be called once the Channel was registered. After the method returns this instance will be removed from the ChannelPipeline of the Channel.

Specified by:

initChannel in class ChannelInitializer<QuicStreamChannel>

Parameters:

ch - the Channel which was registered.

initPushStream

protected abstract void initPushStream(QuicStreamChannel ch)

Initialize the QuicStreamChannel to handle Http3PushStreamFrames. At the point of calling this method it is already valid to write Http3PushStreamFrames as the codec is already in the pipeline.

Parameters:

ch - the {QuicStreamChannel} for the push stream.
