Sub-classing Scomp'd Impl classes

[Edward Blazer]

Hello,

I'm dealing with rather large XML objects that have 10's of thousands of
elements. Instead of using a String object for each elements value, I'd like
to pass a different object that uses a byte[] and have xmlBeans call the
object's toString() method which does all the converting. This would save a
lot of memory. So, I'd like to sub-class the appropriate Impl.class (or
modify the src) generated by scomp such that it delegates the stringValue()
method to the object that is backed by a byte[]. This part is no problem.

The problem arises when calling a parent element's xmltext() method; it
returns a null value. I don't know much about how xmlbeans works
behind-the-scenes, but my guess is that my object with the byte[] needs to
make it to the cursor somehow?

Any ideas for this. Is there a better way to solve my problem?

Thanks,

Eddie
