InternodeConnectionUtils.ByteBufDiscardHandler (apache-cassandra API)

java.lang.Object
- io.netty.channel.ChannelHandlerAdapter
- - io.netty.channel.ChannelInboundHandlerAdapter
  - - org.apache.cassandra.net.InternodeConnectionUtils.ByteBufDiscardHandler

All Implemented Interfaces:

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

Enclosing class:

InternodeConnectionUtils
```
public static class InternodeConnectionUtils.ByteBufDiscardHandler
extends io.netty.channel.ChannelInboundHandlerAdapter
```
Discard handler releases the received data silently. when internode authentication fails, the channel is closed, but the pending buffered data may still be fired through the pipeline. To avoid that, authentication handler is replaced with this DiscardHandler to release all the buffered data, to avoid handling unauthenticated data in the following handlers.
