Hello John,
Great thanks for your help! European soccer champinship also attract lot of
us :-) Enjoy! It's really a good news for your samples, the sooner the
better :-)
In my case, I invoke the ProtocolFilter in CallbackHandler.onConnect() to
send the request to the server and it works, or in another word, the
CallbackHandler.onConnect() kicks off the protocol interaction. Because I
really want the ProtocolFilter to manage its own state/operation itselft
without interaction with the CallbackHandler.
But there are still problems, those are about
1. Context operation type switching or SelectionKey interests switching
Could you pls. give a brief explanation of these switching, maybe something
about Context.setCurrentOpType(), KeyRegistrationState, or anything else?
2. Asynchronously reading/writing in ProtocolFilters
In my case, I use an asynchronous reading operaiton to receive the server's
simple response. Unfortunately, this leads to about 50% cpu polling :-(.
3. State management in ProtocolFilter
In my case, I try to test a stateful protocol interaction by extending the
interaction process to this: the request-response interaction will be
repeated 5 times and then the client initiates to close the connection.
Could you pls. give a brief explanation about how to implement state
management in ProtocolFilter?
