[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?
Regards,
nj

This should probably be in the users list, not dev. All of that
information
is available in the PackageDesc object. For example,
DrlParser parser = new DrlParser();
InputStreamReader reader = new InputStreamReader(
this.getClass().getResourceAsStream( "Misc3.drl" ) );
PackageDescr pkg = parser .parse( reader );
pkg.getGlobals();
pkg.getRules();
etc.
