Interface RuntimeContext<C extends RuntimeContext<C>>

Type Parameters:
C - the type of the implementing class or interface
All Superinterfaces:
Environment, EvaluationListeners, EvaluatorsContext, 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>, EvaluatorsContext
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.

      static final Comparator<Rule> SALIENCE_COMPARATOR

  • Method Details

    • getRuleComparator

      Comparator<Rule> getRuleComparator()

    • setRuleComparator

      void setRuleComparator(Comparator<Rule> comparator)

    • newRule

      @Deprecated RuleBuilder<C> newRule(String name)
      Deprecated.
      this method is deprecated in favor of a more efficient way of building rules, especially for large rule sets. See the new builder() method for details
      Creates a new rule with the provided name.
      Parameters:
      name - rule name
      Returns:
      a new rule builder

    • newRule

      @Deprecated RuleBuilder<C> newRule()
      Deprecated.
      this method is deprecated in favor of a more efficient way of building rules, especially for large rule sets. See builder() for details
      Creates a new unnamed rule.
      Returns:
      a new rule builder

    • builder

      RuleSetBuilder<C> builder()

      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
      Returns:
      new instance of RuleSetBuilder.
      Since:
      3.1.00
