Interface RuntimeContext<C extends RuntimeContext<C>>

Type Parameters:
C - the type of the implementing class or interface
All Superinterfaces:
Environment, EventBus, FluentEnvironment<C>, FluentImports<C>
All Known Subinterfaces:
Knowledge, RuleSession<S>, RuleSetContext<C,R>, StatefulSession, StatelessSession
All Known Implementing Classes:
AbstractSessionWrapper, KnowledgeWrapper
public interface RuntimeContext<C extends RuntimeContext<C>> extends FluentImports<C>, FluentEnvironment<C>, EventBus
The RuntimeContext interface represents the context in which the rules are executed. Both stateful and stateless sessions, as well as Knowledge instances, extend this interface.

    • builder

      RuleSetBuilder<C> builder(ClassLoader classLoader)

      Returns an instance of RuleSetBuilder for building and appending rules to the current context.

      Builder MUST be terminated with the RuleSetBuilder.build() call for changes to take effect.

      Usage BEFORE 3.1.00:

       
 service
      .newKnowledge()
      .newRule()
      .forEach("$a", A.class)
      .where("$a.active")
      .execute();
      Usage AFTER 3.1.00: 
       
 service
      .newKnowledge()
      .builder()       // !! important
      .newRule()
      .forEach("$a", A.class)
      .where("$a.active")
      .execute()
      .build();        // !! important
      Parameters:
      classLoader - the classloader to use.
      Returns:
      new instance of RuleSetBuilder.
      Since:
      3.1.00
