[rules-users] Re: [rules-dev] How to get Fact's type from rule package?

David, Thank you for the reply. I checked the PackageDescr and RuleDescr classes, but there seems no direct methods which would return the fact classes used in the rule. for instance if we have a rule like: rule rule1 when Person(name = "qq") Driver(name = "aa") then ... end from this rule, I want to get [Person, Fact]. In org.drools.rule.Rule class, there is a getDeclaration(), this returns some type information if variable is associated with Fact class, e.g, $p: Person. But in the above case, we just get empty list of declarations. This kind of information is useful when we need to provide a GUI for given rules. Do you have more specific suggestion for this?
