Hello Everybody,
I am not getting, on how to do for loop functionality in drools.
Like for instance, my functionality has :
for(i = 0; i<10; i++)
{
c.setCustomerCount(c.getCustomerCount() + 1);
}
How to translate this code into rule language (.drl).
It would be helpful if anybody could guide me on this.
Thanks and Regards,
Sumeet Karawal

Drools is an inference engine and it let you express your knowledge using
rules.
A rule has 2 parts: CONDITION par and ACTION part.
The CONDITION part is expressed in a drools' proprietary syntax, but in the
ACTION part you can use plain java code.
What you have described looks like an action that needs to be executed when
certain constraints are meet.
So, in your case, you can just write those lines in you action part. They
should work fine.
I recommend you to read the documentation:

Thanks Esteban!!. I got you point. But how to make the rule to run
according to a condition, in a loop.
Also, how can we trigger the firing of one rule from another rule. Like
when the Condition part of a rule satisfies then, in the Action part a
particular rule is triggered and after that the control resumes to the
previous rule, just as we do in nested if else statement.
Thanks & Regards,

Hi Samarat, as Esteban suggested, please read the documentation as for
example your question is answered there very early on in chapter "2.2.1.
Methods versus Rules".

You're thinking procedural. You won't go far this way.
Rules based engined require a different way of approaching problems.
Familiarize yourself with these differences and you will find out that in
most cases you do not need loops or "nested" conditions.
The keyword here is predicate logic.
