Class ProtocolNegotiators.Http2UpgradeAndGrpcHandler

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

io.grpc.netty.ProtocolNegotiators.Http2UpgradeAndGrpcHandler

All Implemented Interfaces:

io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler

Enclosing class:

ProtocolNegotiators

static final class ProtocolNegotiators.Http2UpgradeAndGrpcHandler
extends io.netty.channel.ChannelInboundHandlerAdapter

Acts as a combination of Http2Upgrade and ProtocolNegotiators.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.
