Class PipelineConfigurator

java.lang.Object

org.apache.cassandra.transport.PipelineConfigurator

public class PipelineConfigurator
extends java.lang.Object

Takes care of intializing a Netty Channel and Pipeline for client protocol connections. The pipeline is first set up with some common handlers for connection limiting, dropping idle connections and optionally SSL, along with a handler to deal with the handshake between client and server. That handshake handler calls back to this class to reconfigure the pipeline once the protocol version for the connection has been established.
