Subject Re: _impl and _fieldImpl in PCDataImpl class, are these 2 fields ever used ?
Date Fri, 15 Aug 2008 15:50:22 GMT
_impl and _fieldImpl are space for implementations to store
impl-specific data about the object or its fields.  I don't recall
whether Kodo/OpenJPA currently uses this feature.  Custom mappings
might.
