Examples of org.drools.core.RuleBase.newStatefulSession()

org.drools.core.RuleBase.newStatefulSession()
Create a new WorkingMemory session for this RuleBase. By default the RuleBase retains a weak reference to returned WorkingMemory.
The created WorkingMemory uses the default conflict resolution strategy.
@see WorkingMemory @see org.kie.conflict.DefaultConflictResolver @return A newly initialized WorkingMemory.IMPORTANT: when using the stateful session REMEMBER TO CALL dispose() when you are done with the session.
