Package org.kie.internal.builder

Class KnowledgeBuilderFactory

  • public class KnowledgeBuilderFactory
extends Object
    This factory is used to build the knowledge base resources that are held collectively in KnowledgePackages. The KnowledgePackage also provides the role of 'namespacing'. An optional KnowlegeBuilderConfiguration can be supplied. The KnowledgeBuilderConfiguration is itself created from this factory. The KnowledgeBuilderConfiguration allows you to set the ClassLoader to be used along with other setting like the default dialect and compiler, as well as many other options. 
     KnowledgeBuilder kbuilder = KnowlegeBuilderFactory.newKnowledgeBuilder();

        The KnowledgeBuilderConfiguration.

      • newDecisionTableConfiguration

        public static DecisionTableConfiguration newDecisionTableConfiguration()
        DecisionTable resources require a ResourceConfiguration, that configuration instance is created here. Note that if you are passing a Reader, you must use an InputStreamReader so the encoding can be determined. 
         KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
 DecisionTableConfiguration dtconf = KnowledgeBuilderFactory.newDecisionTableConfiguration();
 dtconf.setInputType( DecisionTableInputType.XLS );
 dtconf.setWorksheetName( "Tables_2" );
 kbuilder.add( new URL( "file://IntegrationExampleTest.xls" ),
                       ResourceType.DTABLE,
                       dtconf );
 assertFalse( kbuilder.hasErrors() );
 KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
        Returns:

      • newScoreCardConfiguration

        public static ScoreCardConfiguration newScoreCardConfiguration()
        ResourceConfiguration for score cards. It allows for the worksheet name to be specified.

        Simple example showing how to build a KnowledgeBase from an XLS resource. 

         KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
 ScoreCardConfiguration scconf = KnowledgeBuilderFactory.newScoreCardConfiguration();
 scconf.setWorksheetName( "Tables_2" );
 kbuilder.add( ResourceFactory.newUrlResource( "file://IntegrationExampleTest.xls" ),
               ResourceType.SCARD,
               scconf );
 assertFalse( kbuilder.hasErrors() );
 KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();

                                                     String systemId)
