handleUpstream

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

从类复制的说明: 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.

指定者:

handleUpstream 在接口中 ChannelUpstreamHandler

覆盖:

handleUpstream 在类中 SimpleChannelUpstreamHandler

参数:

ctx - the context object for this handler

e - the upstream event to process or intercept

抛出:

java.lang.Exception

channelConnected

public void channelConnected(ChannelHandlerContext ctx,
                    ChannelStateEvent e)

从类复制的说明: 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!

覆盖:

channelConnected 在类中 SimpleChannelUpstreamHandler

messageReceived

public void messageReceived(ChannelHandlerContext ctx,
                   MessageEvent e)

从类复制的说明: SimpleChannelUpstreamHandler

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

覆盖:

messageReceived 在类中 SimpleChannelUpstreamHandler

exceptionCaught

public void exceptionCaught(ChannelHandlerContext ctx,
                   ExceptionEvent e)

从类复制的说明: SimpleChannelUpstreamHandler

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

覆盖:

exceptionCaught 在类中 SimpleChannelUpstreamHandler
