Interface ISessionFactory
- Namespace
- NRules
- Assembly
- NRules.dll
Represents compiled production rules that can be used to create rules sessions. Created by RuleCompiler by compiling rule model into an executable form.
public interface ISessionFactory : ISessionSchemaProvider- Inherited Members
Remarks
Session factory is expensive to create (because rules need to be compiled into an executable form). Therefore there needs to be only a single instance of session factory for a given set of rules for the lifetime of the application. If repeatedly running rules for different sets of facts, don't create a new session factory for each rules run. Instead, have a single session factory and create a new rules session for each independent universe of facts.
