handleUpstream

public void handleUpstream(ChannelHandlerContext ctx,
 ChannelEvent e)
                    throws Exception

Description copied from class: SimpleChannelUpstreamHandler

Handles the specified upstream event. Down-casts the received upstream event into more meaningful sub-type event and calls an appropriate handler method with the down-casted event.

Specified by:

handleUpstream in interface ChannelUpstreamHandler

Overrides:

handleUpstream in class SimpleChannelUpstreamHandler

Parameters:

ctx - the context object for this handler

e - the upstream event to process or intercept

Throws:

Exception

channelConnected

public void channelConnected(ChannelHandlerContext ctx,
 ChannelStateEvent e)

Description copied from class: SimpleChannelUpstreamHandler

Invoked when a Channel is open, bound to a local address, and connected to a remote address.
Be aware that this event is fired from within the I/O thread. You should never execute any heavy operation in there as it will block the dispatching to other workers!

Overrides:

channelConnected in class SimpleChannelUpstreamHandler

channelInterestChanged

public void channelInterestChanged(ChannelHandlerContext ctx,
 ChannelStateEvent e)

Description copied from class: SimpleChannelUpstreamHandler

Invoked when a Channel's interestOps was changed.

Overrides:

channelInterestChanged in class SimpleChannelUpstreamHandler

messageReceived

public void messageReceived(ChannelHandlerContext ctx,
 MessageEvent e)

Description copied from class: SimpleChannelUpstreamHandler

Invoked when a message object (e.g: ChannelBuffer) was received from a remote peer.

Overrides:

messageReceived in class SimpleChannelUpstreamHandler

writeComplete

public void writeComplete(ChannelHandlerContext ctx,
 WriteCompletionEvent e)

Description copied from class: SimpleChannelUpstreamHandler

Invoked when something was written into a Channel.

Overrides:

writeComplete in class SimpleChannelUpstreamHandler

exceptionCaught

public void exceptionCaught(ChannelHandlerContext ctx,
 ExceptionEvent e)

Description copied from class: SimpleChannelUpstreamHandler

Invoked when an exception was raised by an I/O thread or a ChannelHandler.

Overrides:

exceptionCaught in class SimpleChannelUpstreamHandler

generateTraffic

private void generateTraffic(ChannelStateEvent e)

nextMessage

private ChannelBuffer nextMessage()
