java.lang.Object
io.netty.channel.ChannelHandlerAdapter
io.netty.channel.ChannelInboundHandlerAdapter
io.netty.handler.codec.ByteToMessageDecoder
org.apache.cassandra.transport.InitialConnectionHandler
All Implemented Interfaces:
io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler
public class InitialConnectionHandler extends io.netty.handler.codec.ByteToMessageDecoder
Added to the Netty pipeline whenever a new Channel is initialized. This handler only processes the messages which constitute the initial handshake between client and server, namely OPTIONS and STARTUP. After receiving a STARTUP message, the pipeline is reconfigured according to the protocol version which was negotiated. That reconfiguration should include removing this handler from the pipeline.
