Seems to me like you are trying to restrict the actionName/Length in the
derived classes (XSD restriction, right)?
If so, I've been disappointed as well. Page 92 of the JAXB 2.0
specification:
<quote>
* base class: A complex type definition can derive by restriction or
extension (i.e. {derivation method} is either “extension” or
“restriction”).
**However, since there is no concept in Java programming
similar to restriction, both are handled the same.**
</quote>
Which, for me, doesn't quite holds all the water one (or no0ne, for this
instance) would expect.
Rationale: I imagine that JAXB could be enhanced to override generated
getters, and hook some code to implement the restriction (or at least
allow the implementation of a plugin specific to one needs). I'm not
saying that is safe to do in all situations, I haven't performed the
in-depth analysis of all implications/consequences; what I'm saying:
this is where I'd start looking into.
Now, the reasons for my frustrations in relation with xjc: it even
refuses to accept customizations related with an "XSD restricted"
property. Wolfgang, please, once again: where should we raise
enhancement suggestions/requests?
Best regards,
no0ne
(newb as well)
