Use Drools 6.0 new PHREAK algorithm by using the 5.5. legacy API

Is it possible to try out the new PHREAKS algorithm but using the conventional API from Drools 5.5

* EDIT: to make the question more precise *

conventional 5.5 API

import org.drools.KnowledgeBase;
import org.drools.KnowledgeBaseFactory;
import org.drools.builder.KnowledgeBuilder;
import org.drools.builder.KnowledgeBuilderFactory;
import org.drools.builder.ResourceType;
import org.drools.io.Resource;
import org.drools.io.ResourceFactory;
import org.drools.runtime.StatefulKnowledgeSession;

instead new Drools 6 API

  import org.kie.api.KieBase;
  import org.kie.api.KieBaseConfiguration;
  import org.kie.api.KieServices;
  import org.kie.api.builder.KieBuilder;
  import org.kie.api.builder.KieFileSystem;
  import org.kie.api.builder.KieScanner;
  import org.kie.api.builder.Message;
  import org.kie.api.builder.ReleaseId;
  import org.kie.api.builder.model.KieBaseModel;
  import org.kie.api.builder.model.KieModuleModel;
  import org.kie.api.builder.model.KieSessionModel;
  import org.kie.api.conf.EqualityBehaviorOption;
  import org.kie.api.conf.EventProcessingOption;
  import org.kie.api.runtime.KieContainer;
  import org.kie.api.runtime.KieSession;
  import org.kie.api.runtime.conf.ClockTypeOption;
Solution

  • It's also possible with the 5 knowledge api in drools 6.0+ by setting a rule engine property:

    drools.ruleEngine = phreak

    Here's how you set in the 5 knowledge api:

    knowledgeBaseConfiguration.setProperty("drools.ruleEngine", "phreak");
