Description

At the 39th Tango Community Meeting, I showed that Multiclasses can be a valid approach for complex device servers: one executable, one Jive entry, and a single home for cooperating and inspectable Tango classes. In this talk, I will present the production pattern I use — a single server combining transport classes, protocol classes, device-specific classes, and a generic interface class — along with a couple of possible optimizations.
