I use a dataflow framework that is driven from XML description files. The framework utilizes dynamically loaded components as Stjepan has described in an earlier post. The framework has been deployed in applications ranging from digital video/audio systems to aviation flight/meteorology equipment in international airports.
Nice! Out of curiosity, (if you can share) what XML syntax did you use? With one of the dataflow systems I worked on I ended up using something like this: <component name="A" type="some_source_type" parameter1="value1" parameter2="value2" /> <component type="some_sink_type" some_other_parameter="other_value"> <input name="A"/> </component> At some point I hope to provide an example that uses XML configuration files to initialize a network, but built on top of the Dataflow Generic Support Layer so that it can be used with any framework with an implemented support layer (in the same way the GUI example does). There are some nice possibilities using Boost.Fusion with reading the parameters from the XML file and providing them type-safely to the constructor of the component.
I hope to have an opportunity to review the Dataflow library.
That would be great! Best, Stjepan
