[rules-users] custom rule creation/parsing

[Dean Jones]

Hello Eugeny,

Not sure if this is the recommended way, but I did something similar
using the classes in the org.drools.lang.descr package. You can create
a PackageDescr from your custom objects and then call
PackageBuilder.addPackage(PackageDescr) and
PackageBuilder.getPackage() to get an org.drools.rule.Package.

I couldn't find any documentation on the org.drools.lang.descr package
(javadoc is pretty minimal as well), but you should be able to work
out what to do, at least for the basic stuff.

Best wishes,

Dean.
