Nope, unfortunately :( it generates readers/writers that just invoke plain old setters/getters/adders for generated models, but that is why maybe is efficient. > >> So, I pushed an initial/prototypal logback-joran2 module in my >> personal fork[2], which APIs are not integrated with the rest of the >> project yet. >> >> Configuration elements are defined in the Modello descriptor[3] which >> enable the generation of Java APIs (included inner Builders/static >> utility methods), the XML Reader/Writer (based on StAX APIs) and the >> XSD that users could integrate in their preferred XML IDE in order to >> enable the validation and auto-complete editing. >> With that approach, users can create their configurations >> programmatically, for free. > > > That's just awesome! > > >> Final format is a little different to the current one, have a look to >> a sample[4] generated via these APIs, but I am working to keep the >> original format as much as I can. > > > Are there any hooks in Modello to support setting component properties, e.g. > appender properties?

Once complete, I think you could evaluate an experimental Joran2 module - which can co-live nicely with existing Joran...
