Re: [rules-users] Is rule introspection available from the Drools API?
The code is there, but it’s not public and not documented, and the code can be a little
hard to understand - as it’s grown organically over the years.
You’ll need to cast and unwrap and look at member vars. Start on the Rule and the lhs
variable. You can always pop onto irc, with live questions,and we’ll try and respond
quickly.

Hello,
is there a way to introspect a Drools file from within java code?
What I need is to be able to identify the facts and the fact attributes that are used in
a given DRL file.
For example if I have a rule stored in a customer.drl DRL file within my project,
containing the following definition:
package myRulePackage
import org.rules.model.Customer
import org.rules.model.Mambership
rule "is eligible customer"
when
$c:Customer(status == "active")
Membership(customer == $c, type == "premium")
then
$c.setEligibilityStatus(true);
end
What i need is a way to understand that this ruleset customer.drl is using two fact types
- Customer and Membership and three of their attributes - Customer.status,
Membership.customer and Membership.type.
I found some information on the internet that such functionality is not supported,
however the information was a bit too old, so I decided to ask again.
Big thanks for the support!
Milen
