If I replace this line with the value that it would return the rule runs perfectly. Do I have to reference this in a certain way because it is an integer?

[rules-users] DRL Pattern match to subclass?
Hi, all,
I'm trying to figure out a way to perform the following pattern match
in a when clause in a drl file. This is with Drools 4.x
I have the following parameterized class (boilerplate omitted):
abstract class PropertyT {
public String getName() {
//...
}
public abstract T getValue();
}
and subclasses such as
class BigDecimalProperty extends PropertyBigDecimal {
public BigDecimal getValue() {
//...
}
}
I then have an interface as such:
public interface Propertied {
public SetProperty? getProperties();
}
and an implementing class:
class Plan implements Propertied {
//...
}
In my rules file, I would like to be able to perform the following
pattern match:
rule Ensure that plan minimum commitment has been met.
agenda-group evaluate-balance
when
$plan: Plan()
$minCommitProperty: BigDecimalProperty(name ==
minimum_commitment, $minCommitment : value) from $plan.properties
then
//...
end
Of course, this results in a runtime rule compilation exception
complaining of type mismatch. Is there any better way to encode this
match than to add all properties to the working memory, match the
desired property as a first-class object, then match against the plan
with Plan(properties contains $minCommitProperty)?
Thanks,
Kris

One addendum - this isn't really a desirable approach since it would
mean I would have to segment my working memory on a plan-by-plan
basis, as various different minimum commitments.

end
So, I have concocted the following abomination:
rule Ensure that plan minimum commitment has been met.
agenda-group evaluate-balance
when
$plan: Plan()
$prop: Property(name == minimum_commitment) from
$scheduledSegment.segment.properties
BigDecimalProperty($minCommitment : value) from $prop.class.cast($prop)
then
//...
end
This (unbelievably) at least compiles and passes my tests; of course,
at the moment I don't have any Property instances with a name of
minimum_commitment that are not instances of BigDecimalProperty. Is
there any way to at least encode an instanceof check into the Property
pattern match to eliminate the possibility of a class cast exception?
How do I reference BigDecimalProperty.class at all?
Actually, this brings me to anotherpressing question - how do I refer
to anything other than a method that obeys the bean property
convention in a from clause?
I've got a number of instances where I'd like to be able to do something like:
when
$cont : Container()
Value() from $cont.value()
then
where Container (a third-party class that I can't change) defines:
interface Container {
public Value value();
}
(in this case, Container is really Option from functionaljava.org, and
value() is really some())
Is it possible to sidestep the bean convention? It seems like the
Drools compiler attempts to convert everything to getter method
without even checking whether an appropriate method exists on the
target class.

[rules-users] How can I configure who is an Admin in Guvnor?
Hello Drools Users, In the Guvnor Documentation ( http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-guvnor/html/ch01.html#d0e185 ) it states that . It is also possible (thanks to JAAS) to define what users have the admin role for Guvnor (note that an Admin user of Guvnor doesn't have to really be a system administrator). I wasn't sure if this meant that there was a way to define Admins from within the Guvnor UI or if it was possible to configure the admin role to read from an LDAP group or some other JAAS method. We are going to be deploying Guvnor to a production environment in the near future, we want to take advantage of Role Based Authorization, we want to start with an empty DB and we don't want to have to deploy with Authorization off, set up roles and then turn it back on. Is this possible? Or did I misinterpret the documentation? Thanks, Steve Ronderos___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] Strategy for initializing objects
Hello I want to achieve this: box1.setX(0) box2.setX(box1.size()); box2.setX(box1.size + box2.size) ... I want to do it with rules, and would like to know what's the best method of initializing (or any other operation with varying data) a group of objects rule init box when b : Box( x == -1) then b.setX(Box.getX()); Box.setX( Box.getX() + b.size); end This does not work. A single box object is matched several times instead of different box objects. What is happening? how come a single box object is matched several times? Why doesnt drools choose other instances of box? What do I need to do to initialize all boxes, once for every box? Thank you. -- robosonia ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Strategy for initializing objects
Your goal and the presented code aren't clear to me. The consequence (after
then) contains calls to static/class methods (Box.setX()) which isn't going
to change anything in your fact object. The call b.setX() might change your
object, but this depends on what the class method Box.getX() returns.
Assuming Drools 5, a typical consequence would look like
b: Box(...)
then
modify( b ){
setX( ... )
}
end
