Get all rules

[Yuriy Petrov]

Hello,

How can I get at run time the set of all rules (list of rule names at least) in kie base using Drools API?

Thanks,

Yuriy

Hi Yuiry,

one option would be to use the AgendaEventListener.

This way you should get all rules (names) fired or considered for firing.

I think that over time you would get all the rules (names) that are used.

Cheers.

Well, digging in Drools API javadocs I've found how to get what I need:

1. Get kie session object (there are various ways to get this object), then get kie base object from the session

2. Kie base class provides the method Collection<KiePackage> getKiePackages() - call this method

3. For every package in the returned collection run the package's method Collection<Rule> getRules()

That's it :)

Regards,

Yuriy
