Re: [rules-users] Non short circuit ANDing

Gents, this is a really interesting discussion and I wish I had more time to participate.. I agree with Stephen that some constraints are really worthy monitoring, while others are simply "filters".. Wolfgang's mention of "near misses" is potentially a hot topic, I have been experimenting with "imperfect" rules which are more robust in that sense and provide better traceability, but that is not yet implemented in the core engine. I would also point out that one thing is monitor constraints for "logging" or "auditing" purposes, another is the ability to specify different behaviours (i.e. consequences) according to the success vs failure of an evaluation. To this end, and following on the "extending" rule thread, it has actually been planned and partially implemented.. it's only an experimental feature (@Mario, any update/clarification?), so it's probably not well documented. But I would point you to these links: http://blog.athico.com/2012/09/conditional-branches-with-sub-blocks.html https://community.jboss.org/wiki/BranchCEs with the warning that it's still experimental and, while adopting "familiar" keywords (if, then, else, switch), their semantics is different from the usual imperative language one, and in fact could enable some of the "extend" capabilities that have been invoked in the last couple of posts.

Hopeful that the Drools gurus will comment explicitly on all these approaches (and/or the approach suggested by another of using Working Memory listeners). > > _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
