Class KnowledgeBaseFactory

  • public class KnowledgeBaseFactory
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");

      • newKnowledgeBase

        public static InternalKnowledgeBase newKnowledgeBase()
        Create a new KnowledgeBase using the default KnowledgeBaseConfiguration
        Returns:
        The KnowledgeBase

      • newKnowledgeBase

        public static InternalKnowledgeBase newKnowledgeBase​(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
