[rules-users] 5.3.0 Faster Complation?
Hi, From documentation of 5.3.0: 2.1.1.4. Faster compilation Thanks to many improvements and optimizations made on both MVEL library and Drools internals, the DRL compilation is now at least 3 times faster for both MVEL and Java dialects. Does it really affect the runtime execution of already compiled serialized rules in production? Any technical details will help. Thanks, saleem ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] AgendaGroup and AgendaFilter
Hi,
Previous Code from drools 3.x:
Below is an example of overridden method in a class that implemented
org.drools.spi.AgendaFilter
public boolean accept(Activation activation) {
boolean evaluateRule = false;
String agendaGroup = activation.getRule().getAgendaGroup();
if (functionalArea.equalsIgnoreCase(agendaGroup) {
evaluateRule = true;
}
return evaluateRule;
}
Drools 5.x
Now I have changed the implementation to
org.drools.runtime.rule.AgendaFilter
How do I re-write the bold-italic line inside the method when variable
activation is now an instance of org.drools.runtime.rule.Activation;
It doesn't support activation.getRule().getAgendaGroup();
Thanks,
saleem

Yes but for this i will be obliged to create a POJO of an object. And
for attributes of that object in DSL i can define values that can take this
attribute?
Maybe i don't understand but i don't see how to do with this.
My case :
I have Maps in the session. Each Map has for example 5 properties
(prop1, prop2, prop3, prop4, prop51) and the value is a string. The
Map is MapString, Object but generally Object is a String.
So in the When clause i have something like that :
$m : Map((this[prop1] == test1))
I have included java.utils.Map in Guvnor. So when i add a when clause i
can choose Map in the list but impossible to have prop1 to prop5 in a drop
down list for attributes of the Map.
Would it be possible to create a Pojo for Map or would it be in
conflict with the Map of Java?

You can define enumerations for a particular attribute.
Inside a DSL you can constrain a placeholder with that enumeration.
And finally, enums can be static, or dynamic (a interface to implement
that returns a list of values).

For now, our project is planning on using spreadsheets and a drools server. The test project we are working on accepts a movie name from an external source and creates a Movie object that is passed to the rules. The first rule looks at the movieName attribute and assigns it a movieStar using the Movie objects setMovieStar call. We have printLn statements before and after this action to confirm that it does in fact work. The second rule, where things go wrong, checks the MovieStar attribute, but no matter what we've just set it to, it always uses the value (NoStarYet) that was originally created when we create the Movie object in our Java code in the condition of our second rule. We've tried using the getMovieStar call in the condition, but it has been throwing errors when we startup the Drools Server. When we retreive the Movie object from the resultSet, the movieStar attribute is set correclty, but we can't get our flow to go as expected. This really seems like a simple issue, but we've had no luck with it. Any thoughts? Does the rules engine use the getter methods for conditions or does it use the values from the entityXML we pass in? Is there a way to make the engine update the object between running each rule? Any help is appreciated greatly. -Inline Attachment Follows- ___ rules-users mailing list rules-users@lists.jboss.org http://mc/compose?to=rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Hi, I need to have two objects of the same class present in the working memory at the same time. Both objects can have other nested objects of different classes. The reason is I need to compare data change b/w two objects. E.g; originalObject_A.getPersonTO().getAge() != changedObject_A.getPersonTO().getAge() I am using Drools 3.0, DRLs and DSL. My question is: how do I assert two objects belonging to the same class in working memory in order to access them both in DSL. E;g I can do: workingMemory.assertObject(originalObject_A); //instance of class A workingMemory.assertObject(changedObject_A); //instance of class A and in DRL I can write: [when]There is an instance with = originalObject_A:ClassA() how do I get the changedObject_A in dsl. How does drools know which object I am requesting? I hope my question is clear. Is it even possible in drools 3.0?
