Hi all,
I want to implement some handshake protocol, say..
1. Client: WhatDate 2. Server: 5Aug 3. Client: WhatYear 4. Server: 2006 5. Client: WhatTime 6. Server: 1005
So, for the client:- (pseudo code) def connectionMade(): send "WhatDate" state = askingForDate def lineReceived(data): switch state: askingForDate: date = data send "WhatYear" state = askingForYear break askingForYear: year = data send = "WhatTime" state = askingForTime break askingForTime: time = data state = initialState disconnect
The switch case becomes gigantic as the protocol grow. Instead of keeping states, are there better ways to implement?
I know this expands the scope of what you have to learn, but look at State Machine Compiler. You can create a single object, and then generate all the state management code from SMC. -- If you don't know what you want, you probably need a nap.
