- Enclosing class:
- ProtocolNegotiators
static final class ProtocolNegotiators.Http2UpgradeAndGrpcHandler extends io.netty.channel.ChannelInboundHandlerAdapter
Acts as a combination of Http2Upgrade andProtocolNegotiators.GrpcNegotiationHandler
. Unfortunately, this negotiator doesn't follow the pattern of "just one handler doing negotiation at a time." This is due to the tight coupling between the upgrade handler and the HTTP/2 handler.
