[jboss-dev-forums] [Design of JBossCache] - Re: Need to make enhacements to CacheListener API

[manik.surtani@jboss.com]

Ok, so now we're at CR2.  Not the time to be changing APIs, but I understand that if we need it we need it.  The callbacks in consideration are block/unblock/startTx/endTx, right?

I like Jason's approach to using annotations rather than the interface methods - makes things easier for people who don't want to implement everything.

What do people think?  Can/should we:

1)  Live with the current API
2)  Add to the existing interface
3)  Switch to an annotation based approach
4)  Do both 2 and 3, providing users with both ways of implementing listeners?

I think if we can live with (1) I suggest we do that.  Failing that, I'd go with (3), since we'd be breaking compat with CR2 anyway.  Then (2) and finally (4) which I think doesn't add much value.

I'd like to do this for CR3, and will hold back CR3 until we have a clear decision on this.
