Class ProtocolNegotiators.AbstractBufferingHandler

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

io.netty.channel.ChannelDuplexHandler

io.grpc.netty.ProtocolNegotiators.AbstractBufferingHandler

All Implemented Interfaces:

ChannelHandler, ChannelInboundHandler, ChannelOutboundHandler

Enclosing class:

ProtocolNegotiators

public abstract static class ProtocolNegotiators.AbstractBufferingHandler
extends ChannelDuplexHandler

Buffers all writes until either writeBufferedAndRemove(ChannelHandlerContext) or fail(ChannelHandlerContext, Throwable) is called. This handler allows us to write to a Channel before we are allowed to write to it officially i.e. before it's active or the TLS Handshake is complete.
