OK let me try to see if I understand properly. Mainly, you want to be
able to support two protocol
(first)
client ---> protocol_a ---> server
(second)
client ---> protocol_b ---> server
where protocol_b is the 'stop' string. Security wise, I would not mix
the handling of protocol_a and protocol_b, but instead create 2
SelectorHandler, one for protocol_a, one for protocol_b. For the
SelectorHandler listening for protocol_b, I strongly recommend you bind
the Selectorhandler (the address) to 127.0.0.1 as if you open it to all
port, some malicious use can re-start your server.
For protocol_b, just write a simple ProtocolFilter that take read the
String from the byteBuffer, and if the byteBuffer contains the expected
String ('stop'), the do something like:
public boolean execute(Context ctx){
// Read from the ByteBuffer
// If stop, then
new Thread(){
public void run(){
ctx.getController().stop();
ctx.getController.start();
}.start();
}
That should work. Did I understood your question correctly?
Thanks!
