Examples of org.drools.StatelessSession

org.drools.StatelessSession
This represents a working memory session where state is not kept between invocations. This is typically used for "decision services" where the rules are provided all the data in one hit, and a conclusion reached by the engine. (there is no accumulation of facts/knowledge - each invocation is on a fresh session). Each created StatelessSession can be call execute() any number of times, in a stateless manner however the GlobalResolver, unless set each time, is shared between each execute() method call. Care should be used when using the async versions of the methods, consult the javadoc for the specific information.
