Re: [rules-users] Declarative agenda final API
I thought of using declarative agenda because for each fact I would like to know all potential rules which it could activate but I want finally to fire (execute RHS) only for the rule with highest priority. Thanks to adding rule with @activationListener(‘direct’) I am able to block all rules, add them to some list and later unblock and execute rule only the highest priority. Do you think I can use some other Drools API, features to achieve this kind of behaviour? Is it possible to unblock rule based on salience? (something like: when $a : Activation(*salience * $value) then unblock) Thanks, Marcin -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-Declarative-agenda-final-API-tp3684502p3693182.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Declarative agenda final API
I was able to achieve earlier described logic by adding AgendaEventListener with activationCreated and afterActivationFired to knowledge session. About Activation: it looks like in org.drools.runtime.rule.Activation there is no salience however it is in org.drools.spi.Activation. For delarative agenda API org.drools.runtime.rule.Activation needs to be used so my question how to filter Activations based on salience is still valid.

I'm not sure if it's a bug rather a problem with the Configurator (I don't know TBH) that might need to do more work.

Re: [rules-users] setting different value in consequence ( RHS part) based on a conditional check
Hello Frank, there is nothing wrong with your reason A and B. But the decision what to include in the decision logic is an engineering decision, and in engineering you always have a certain leeway within the margin set by mathematical or natural laws. Is maintenance easier if you have 2 rules where there is absolutely no decision in RHS code or is it better to have one rule plus a simple mapping function? What if this distinction must be made in a number of rules so that you have 2*n compared to n plus one function? As for C, I just don't know how you envisage a business user and his or her capabilities. Understanding rules that go beyond the noncommittal there is a thing with property X equal to x and property Y equal to y is not something a layman can be expected to have at his fingertips. But, assuming this business user can read logic: there is not good reason why he or she shouldn't be able to understand a simple functional mapping.

Re: [rules-users] setting different value in consequence ( RHS part) based on a conditional check
Esteban, we already have several scores of rules in place. the requirment is to change the rule(s) in such a way as to keep it minimal and still achieve the result expected. having to write additional rules would be the last option. hence, I was more interested in using a function if I could. eventually, we decided to add a new rule( just one) that comes later in the ruleflow so as to update all matching facts with the status. This leaves all the scores of rules in place untouched and updates the matching facts in one rule . as per the business needs and ruleflow, this seemed the best solution. -- View this message in context: http://drools.46999.n3.nabble.com/setting-different-value-in-consequence-RHS-part-based-on-a-conditional-check-tp3690826p3694682.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] bytecode representation of rules
Tough question to answer as not everything in a DRL file becomes bytecode, and not all in the same place. For instance, rule consequences and other semantic code blocks, when using the java dialect, will become a class that is code generated and compiled in memory. You can see that code by setting the dump dir option in the KnowledgeBuilderConfiguration object (or -Ddrools.dump.dir=path on the command line). Constraints on the other hand will become a mix of JIT bytecode and/or MVEL expressions and/or object accessors, depending on several factors. Since they are shared among multiple rules, they don't belong to a single rule in particular, but become part of the Rete network, that is basically an in-memory data structure.
