Hey people,
while still in vacation, I managed to get a phone line and answer you
(mountains in Italy are not so plenty of phone lines working well :)
So, my status is this:
I have a full working stateful cache, with overager and resizer, changed
also the EJX gui to reflect the new cache structure and setting options. It
does run the TestBeans.jar and many other tests I've written.
I'm finishing these days the entity cache, but given the experience on the
stateful I think I'll be done in few days (but please leave me some vacation
left until monday :)
Marc, I'm reading the 500+ email I've lost in these days (so maybe I don't
have the full picture yet), but with Rickard we agreed that there will be a
class for entity and stateful cache, and an interface for the algorithm that
the cache will use; the class is delegating the real cache work to an
implementation of this interface. Is this acceptable to you ? This will
leave pluggable the cache performance, algorithm and settings (I made the
suitable changes also to the EJX GUI and to jboss.xml to support this). Up
to now there is only one implementation of the CachePolicy interface: the
one for the LRU algorithm, but there are open possibility to other
algorithms as well.
If you can answer in minutes OK, otherwise I will read your answer(s) on
monday.
Bye
Simon
