Abstract Class Persistence

[Craig L Russell]

I thought I'd describe my understanding of PAC so we have a common basis for discussion.

1. interface PIXXX vs. abstract class PACXXX

2. PIXXXImpl implements PIXXX vs. PACXXXImpl extends PACXXX





That's it.

P.S. A good JDO? O, Gasp!

The difference between Persistent Interface and Persistent Abstract Class is: 3. All methods in PIXXX must be properties (corresponding get/set methods) vs. all abstract methods in PACXXX must be properties. 4. PIXXXImpl implements all property methods vs. PACXXXImpl implements all property methods. I think that JPOX has already done the hard part in getting PI to work. The remaining work is "mapping" the concepts of PI to PAC. If you point me in the right direction, I'll try to make a patch for JPOX.
