RE: Abstract Classes vs. Interfaces

Yakuu provides a good comparison of abstract classes versus interfaces. This is an interested read for me, since I've only started using both of these in the last year - and only because I've seen/copied/extended other programmer's code. After using them for that long, I have to say that there's still doesn't seem to be much of a point. Of course, I'm rarely using mutliple inheritence and none of my projects have gone through a major refactoring. I'm willing to bet that Dave is happy he decided to use interfaces in Roller. The Castor -> Hibernate conversion probably would've sucked without them - or did they create more work?!

Matt, why did Roller move to Hibernate from Castor?

We didn't "move" per se - we just added Hibernate as a persistence option. Dave did discover that Hibernate is twice as fast as Castor though.
