[rules-users] Fact Names in a Model

[Esteban Aliverti]

Well, there might be a way to do what you want, but you will need to go to
the dark side of drools :) (basically means magical castings)

A KnowwledgeBase contains one or more packages, and inside the packages is
where the Declared Types live.
So, using this code (I didn't test it but it should work), you can access
all your declared types of all the packages in a knowledge base:

Set<String> declaredFactTypes = new HashSet<String>();
        Collection<KnowledgePackage> knowledgePackages =
kbase.getKnowledgePackages();
        for (KnowledgePackage knowledgePackage : knowledgePackages) {
            //the key of this map is the simple name of the declared type
and not the fqn
            Map<String, TypeDeclaration> typeDeclarations =
((KnowledgePackageImp)knowledgePackage).pkg.getTypeDeclarations();
            //collect all the keys in the set
            for (String type : typeDeclarations.keySet()) {
                //store the fqn of the declared types to avoid name
collision
                declaredFactTypes.add(knowledgePackage.getName()+"."+type);
            }
        }
