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!
