Emulating a sessions in Netty server.

[Frederic Bregier]

Hi Karasko,

You can use a ConcurrentHashMap. For the ID, you can use if you want the
channel.getId().

Also, if you implement your business handler (the last in the pipeline) such
that this handler is new for every channel connection, then you have
directly the possibility to implement your own data for the session in this
handler.
To do that (according to your other post), it could be something like:
ServerPipelineFactory.java
<code>
   public ChannelPipeline getPipeline() throws Exception {
        ChannelPipeline pipeline = pipeline();
        pipeline.addLast("cmdDecoder", new MyCommandDecoder());
        pipeline.addLast("stringEncoder", new StringEncoder("UTF-8"));
        MyHandlerObj handler = new ServerHandlerObj(); 
        pipeline.addLast("handler", handler);
        return pipeline;
    }
</code> 
Then in you MyHandlerObj, you could have your own data as private attribute
of the class.
Therefore, each data will be attached to one specific channel.
