Example 3 with StatelessKnowledgeSession

use of org.drools.runtime.StatelessKnowledgeSession in project jBPM5-Developer-Guide by Salaboy.

the class RulesHelper method evaluate.

public static boolean evaluate(Car car) {
    if (cachedResults.containsKey(car.getName())) {
        return cachedResults.get(car.getName());
    }
    StatelessKnowledgeSession session = createStatelessSession("good_old_patterns/car-sell-or-drop-complex-decision.drl");
    List list = new ArrayList();
    list.add(car);
    // Get external information that you don't want to keep in the process, for example:
    //   - Call an external service to get information about the stock market
    //   - Check the average price for this type of cars in ebay
    //   - Check for the competitors prices in the last two months
    // We can get a metric about the current status of the market
    // when the process is being executed and use that to influence our decision
    MarketMetric metric = new MarketMetric(0.8);
    list.add(metric);
    session.execute(list);
    cachedResults.put(car.getName(), metric.getResult());
    return metric.getResult();
