[rules-users] Accumulator - Syntax question

Re: [rules-users] immediate vs path bound variables wrt performance?

Ok, I think I just found my answer, from 4.8.2.1 'Note: Nested accessors have a much greater performance cost than direct field accesses, so use them carefully." But is the simple case in the previous post considered "nested"? -- View this message in context: http://www.nabble.com/immediate-

[rules-users] immediate vs path bound variables wrt performance?

The docs state that == with bound variables is very fast due to hashing. The example only shows a simple bound value, eg Person( likes : favouriteCheese ) Cheese( type == likes ) In the following will drools create an implicit hashed variable for '$p.likes' and yield the same performance?

[rules-users] Scaling to large numbers of rules

I am hoping that I am doing something wrong here and that one of you can point me in the right direction. Can anyone provide some advice on scaling up the number of rules in a single KnowledgeBase? While I have seen all sorts of reports on having lots of facts, I have not seen anything about hav

[rules-users] Drools as Lexer / Parser (sequential data processing)

Hello group, I recently had the idea: "A rule system (like Drools) is ideal for making programs with complex rules simpler. Writing a lexer or parser can be non-trivial. So, is it possible and also meaningful to express such a task with rules?" Anyone here who maybe tried that already? The two

Yeah, the docs rightly state that you shouldn't depend too heavily on a given rule firing order: https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-expert/html_single/index.html#d0e1572 Scroll down to "3.3.4.1. Conflict Resolution" They also say tha

Certainly. And while containsAll may work, mattering the size and nature of the collections involved (linear vs constant time existence check) it might not perform as well as your first solution. --- On Wed, 9/2/09, Wolfgang Laun wrote: > From: Wolfgang Laun > Subject: Re: [rules-users] for

Re: [rules-users] question on drools and method calls on facts

I have to disagree on one point. Having fact classes with methods that modify the object in addition to the usual setters is not dangerous, it's called "encapsulation" or "information hiding" and is a common OO pattern. Now, in the rules context, you have to inform the engine that the object h

[rules-users] forall/from/eval/contains: odd DRL syntax error

A rule has to ascertain that all elements in a Listin a Collector occur in the matching BoxResponse's Set. There is just one BoxResponse per Collector. This here works fine: rule matchCollectorResponse when $c : Collector( $ebsList : elemBoxStatusList, $gsSet : globalStatusSet )

Bernd, Something didn't exist as of Drools 4.x (at least nothing official). With the latest release of Drools, the amount of code needed to be written to compile is actually pretty small. Making a Maven plugin would not be that difficult. I've made one that is just a couple of hundred lin
