Examples of io.netty.handler.codec.http2.AbstractHttp2ConnectionHandler

io.netty.handler.codec.http2.Http2TestUtil.Http2Runnable
Abstract base class for a handler of HTTP/2 frames. Handles reading and writing of HTTP/2 frames as well as management of connection state and flow control for both inbound and outbound data frames.
Subclasses need to implement the methods defined by the {@link Http2FrameListener} interface forreceiving inbound frames. Outbound frames are sent via one of the {@code writeXXX} methods.
It should be noted that the connection preface is sent upon either activation or addition of this handler to the pipeline. Subclasses overriding {@link #channelActive} or {@link #handlerAdded}must call this class to write the preface to the remote endpoint.
