I'm not trying to handle all cases under the sun. But... we've chosen NOT to use an XML Schema based XML IO framework (like JAXB or Jackson), instead we've invented our own. I know we do JSON as well, but so does Jackson and it likely also has a plugin for YAML. So now, every time I'm looking for some minor improvement, it means tweaking our custom framework or adding boilerplate code to plugins. It's a pain, but that's where we are today. At least now, with the new type converters, I get the type conversion from to int for free :-)
In this case, I meant, you can only use attribute A or B. It is probably worth stepping back and looking at the big picture and whether we want to invest in improving the current config IO framework or at least consider if Jackson would be a better fit. Likely not for 2.0 ;-) Gary On Mon, Jun 2, 2014 at 4:03 AM, Ralph Goers <rgo...@apache.org> wrote: > Are you looking for annotations to handle every kind of thing you might > like to do instead of just putting a couple lines of code in the factory > method?
