hi,
is it possible to check if a rule has been defined with a global as below?
global MyObject obj;
rule
when
then
Basically, i'm running below code:
ksession = kbase.newStatefulKnowledgeSession();
ksession.setGlobal("obj", new MyObject());
but if a rule doesn't have global definition my code throws an exception.
What i'd like to do is something like
ksession.getGlobal('"obj") or
ksession.checkGlobalExist('"obj").
Unfortunately the first method doesn't work as it doesn't check if a global
has been declared in a rule

What about ksession.getGlobals().get("obj")?

this can't be used because it returns null even if the global has been
defined in a rule

So you want to know, given any DRL in any Package, if you need to
programmatically set the value of a Global on a KnowledgeSession?

Any public API to ascertain whether a DRL package needs a global to be
inserted?
E.G. a DRL has global defined within it, the DRL is loaded into a
KnowledgePackage, can you introspect the package to find out if it contains
a global, it's datatype and name?
With kind regards,
Mike

KnowledgePackageImp and org.drools.rulePackage are not in the
"stable" part of the API, but this is how:
KnowledgePackage kPackage = ...;
KnowledgePackageImp kPackageImp = (KnowledgePackageImp)kPackage;
org.drools.rule.Package package_ = kPackageImp.pkg;
// globals: key is name, value is type name
Map<String, String> name2global = package_.getGlobals();
I have frequently urged for everything that can be written in DRL to be
accessible though the "stable" API. It can't be "unstable" if it
is in the
DRL language, right?
