[rules-users] To access at the fact object
Hi,
I have the drools rule (made in guvnor server) :
1. | rule "driverRule"
2. | salience 10
3. | dialect "mvel"
4. | when
5. | Driver( driverAge : age > 18 && < 65 )
6. | then
7. | Driver fact0 = new Driver();
8. | fact0.setName( "TOTO" );
9. | insert( fact0 );
10. | end
... and the java code source :
KnowledgeAgent agent =
KnowledgeAgentFactory.newKnowledgeAgent("/Guvnor.properties");
KnowledgeBase ruleBase = agent.getKnowledgeBase();
StatefulKnowledgeSession workingMemory =
ruleBase.newStatefulKnowledgeSession();
Driver d = new Driver("Jack", 28, null);
workingMemory.insert(d);
workingMemory.fireAllRules();
for(Iterator i = workingMemory.getObjects().iterator(); i.hasNext();)
{
Object obj = i.next();
System.out.println(obj.getClass().getCanonicalName());
if (obj instanceof Driver)
{
System.out.println("Driver name => " + ((Driver)obj).getName());
System.out.println("Driver age => " + ((Driver)obj).getAge());
}
}
But the drools rule changes the driver name "Jack" by "TOTO", but in
the
console the initial name "Jack" is always displayed.
How to access at the objet who is in knowledge base (the modified objet) ?
Thank. ;)
