[Hibernate-devel] refactorings for collection caching

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

I've just finished the two refactoring tasks I indicated were necessary
for the collection cache. What I've done is:

(1) given the ScheduledXXXXX classes an
        afterTransactionCompletion()
    method so that they can release any cach softlocks they acquired from
    the execute() method.

(2) refactored assemble() and disassemble() onto the Type hierarchy

Now the collection cache should be easy to finish off. The remaining steps
are:

(1) implement methods on the PersistentCollection heirarchy to extract
    the state of the various collection types.
(2) implement the cache on CollectionPersister, following the model on
    ClassPersister ( softlock(), lock(), cache() + getCached() ). Its
    a fair bit simpler for this case 'cos we don't need to worry about
    circular references or polymorphism :)
(3) wire in calls to CollectionPersister.softlock(), releaseSoftLock()
    from the ScheduledCollectionXXXXXX classes
(4) wire in a call to CollectionPersister.cache() when the collection
    is initialized ... and a call to CollectionPersister.getCached()
    when the collection is retrieved.

Are you down for this John?
