Class RuleBaseFactory

java.lang.Object
org.drools.core.impl.RuleBaseFactory
public class RuleBaseFactory extends Object

This factory will create and return a KnowledgeBase instance, an optional KnowledgeBaseConfiguration can be provided. The KnowledgeBaseConfiguration is also itself created from this factory. 

 KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();

Create sequential KnowledgeBase using the given ClassLoader. 

 Properties properties = new Properties();
 properties.setOption( SequentialOption.YES );
 KnowledgeBaseConfiguration kbConf = KnowledgeBaseFactory.newKnowledgeBaseConfiguration(properties, myClassLoader);
 KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(kbConf);

The above could also have used the supported property 

 properties.setProperty( "org.kie.sequential", "true");

    • newRuleBase

      public static InternalRuleBase newRuleBase()
      Create a new KnowledgeBase using the default KnowledgeBaseConfiguration
      Returns:
      The KnowledgeBase

    • newRuleBase

      public static InternalRuleBase newRuleBase(String kbaseId)
      Create a new KnowledgeBase using the default KnowledgeBaseConfiguration and the given KnowledgeBase ID.
      Parameters:
      kbaseId - A string Identifier for the knowledge base. Specially useful when enabling JMX monitoring and management, as that ID will be used to compose the JMX ObjectName for all related MBeans. The application must ensure all kbase IDs are unique.
      Returns:
      The KnowledgeBase
