org.drools.core.StatefulSession
A stateful session represents a working memory which keeps state between invocations (accumulating facts/knowledge). Caution should be used when using the async methods (take note of the javadocs for specific methods). IMPORTANT: Remember to call dispose() when finished with this session.
