Class StreamingInboundHandler

java.lang.Object

io.netty.channel.ChannelHandlerAdapter

io.netty.channel.ChannelInboundHandlerAdapter

org.apache.cassandra.streaming.async.StreamingInboundHandler

All Implemented Interfaces:

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

public class StreamingInboundHandler
extends io.netty.channel.ChannelInboundHandlerAdapter

Handles the inbound side of streaming messages and stream data. From the incoming data, we derserialize the message including the actual stream data itself. Because the reading and deserialization of streams is a blocking affair, we can't block the netty event loop. Thus we have a background thread perform all the blocking deserialization.

Method Detail

handlerAdded

public void handlerAdded(io.netty.channel.ChannelHandlerContext ctx)

Specified by:

handlerAdded in interface io.netty.channel.ChannelHandler

Overrides:

handlerAdded in class io.netty.channel.ChannelHandlerAdapter

channelRead

public void channelRead(io.netty.channel.ChannelHandlerContext ctx,
                        java.lang.Object message)

Specified by:

channelRead in interface io.netty.channel.ChannelInboundHandler

Overrides:

channelRead in class io.netty.channel.ChannelInboundHandlerAdapter

channelInactive

public void channelInactive(io.netty.channel.ChannelHandlerContext ctx)

Specified by:

channelInactive in interface io.netty.channel.ChannelInboundHandler

Overrides:

channelInactive in class io.netty.channel.ChannelInboundHandlerAdapter

exceptionCaught

public void exceptionCaught(io.netty.channel.ChannelHandlerContext ctx,
                            java.lang.Throwable cause)

Specified by:

exceptionCaught in interface io.netty.channel.ChannelHandler

Specified by:

exceptionCaught in interface io.netty.channel.ChannelInboundHandler

Overrides:

exceptionCaught in class io.netty.channel.ChannelInboundHandlerAdapter

shutdown

public static void shutdown()

Shutdown for in-JVM tests. For any other usage, tracking of active inbound streaming handlers should be revisted first and in-JVM shutdown refactored with it. This does not prevent new inbound handlers being added after shutdown, nor is not thread-safe around new inbound handlers being opened during shutdown.

trackInboundHandlers

public static void trackInboundHandlers()
