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

channelOpen

public void channelOpen(ChannelHandlerContext ctx,
 ChannelStateEvent e)
                 throws Exception

Description copied from class: SimpleChannelUpstreamHandler

Invoked when a Channel is open, but not bound nor connected.
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:

channelOpen in class SimpleChannelUpstreamHandler

Throws:

Exception

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

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:
