Method Detail

handleProtocolNegotiationCompleted

public void handleProtocolNegotiationCompleted(io.grpc.Attributes attrs)

Triggered on protocol negotiation completion.

It must me called after negotiation is completed but before given handler is added to the channel.

Parameters:

attrs - arbitrary attributes passed after protocol negotiation (eg. SSLSession).

notifyUnused

public void notifyUnused()

Calling this method indicates that the channel will no longer be used. This method is roughly the same as calling Http2ConnectionHandler.close(io.netty.channel.ChannelHandlerContext, io.netty.channel.ChannelPromise) on the channel, but leaving the channel alive. This is useful if the channel will soon be deregistered from the executor and used in a non-Netty context.
