Hi,
I am trying to parse this .clp file from the documentation.
(deftemplate person (slot firstname) (slot lastname) (slot age))
(defrule welcome-toddlers
"Give a special greeting to young children"
(person {age < 3})
=>
(printout t "Hello, little one!" crlf))
Here my Code:
public static void main(String[] args) throws FileNotFoundException,
IOException, JessException {
Rete engine = new Rete();
FileReader file = new FileReader("M:/ikor/myrules.txt");
Context context = engine.getGlobalContext();
try {
Jesp parser = new Jesp(file, engine);
Object result = Funcall.TRUE;
while (!result.equals(Funcall.EOF)) {
result = parser.parseExpression(context, false);
if (result instanceof Defrule) {
Defrule rule = (Defrule) result;
ConditionalElement ce = rule.getConditionalElements();
int gs = ce.getGroupSize();
for (int j=0;j<gs;j++) {
ConditionalElement e = ce.getConditionalElement(j);
System.out.println(e.toString());
}
}
}
} finally {
file.close();
}
}
I only get "Main:: person" .
How can I get {age < 3} ?
Thanks a lot
Bernd Enders
