Yes, I'm using the reflection API to find out classes and fields.
I say that the above code is a mess because it still has to check for
each possible type and take the appropriate action. As you can see, it
covers bytes, characters, integers, longs, doubles, bigIntegers,
strings, objects, byte arrays, char arrays, int arrays, long arrays and
double arrays. Other types, like short integers, or string arrays etc.
are not covered (and I hope they are not such important). BTW, I just
notice that booleans (and boolean arrays) are also missig; booleans
might be needed.
I cannot see a generic way to do that.
Cheers,
