Interface Knowledge

All Superinterfaces:

Environment, EvaluationListeners, EvaluatorsContext, FluentEnvironment<Knowledge>, FluentImports<Knowledge>, RuleSet<RuleDescriptor>, RuleSetContext<Knowledge,RuleDescriptor>, RuntimeContext<Knowledge>

All Known Implementing Classes:

KnowledgeWrapper

public interface Knowledge
extends RuleSetContext<Knowledge,RuleDescriptor>

Knowledge is a preprocessed ruleset. Although the engine allows direct creation of rule sessions, having a prepared ruleset enables faster instantiation of sessions. Building knowledge instances especially makes sense if the rules use literal conditions and therefore require a very CPU-intensive compilation stage.
