[Hibernate-devel] Collections

[Gavin_King/Cirrus%<CI...@ci...>]

I finally got round to fixing the implementation of collection updates.
This meant

 * using some of Doug Currie's code for deep lazy collections
 * using some of Doug's ideas but implementing them for all collections

Previously, when a collection element changed, the entire collection was
removed and then recreated. This was okay for small collections but was
clearly bad for very large collections. Fixing this had been sitting on the
TODO list since the earliest iterations of the project....

Now:

 * new elements are INSERTed
 * removed elements are DELETEd one at a time
 * modified elements are UPDATEd

This change actually makes my test suites *slower* but we can expect it to
scale much, much better.

So 1.1 beta 6 is just about ready to go. I've just been doing some
documentation refresh, etc....

Also I'll post an ArgoUML diagram of the highlevel design of Hibernate here
later today. Hopefully some documentation will make it easier for people to
contribute.
