Method Detail

handleUpstream

public void handleUpstream(ChannelHandlerContext ctx,
                           ChannelEvent e)
                    throws java.lang.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:

java.lang.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.

channelConnected in class SimpleChannelUpstreamHandler

Throws:

java.lang.Exception

                            MessageEvent e)
