[rules-users] how to check if a global has been declared in a rule

[Wolfgang Laun]

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?
