Examples of org.drools.time.SessionPseudoClock

org.drools.time.SessionPseudoClock
A clock interface for the implementation of pseudo clocks, that are clocks where the user have control over the actual clock working. Pseudo clocks are particularly useful for simulations, "what if" scenario runs, and for tests. @author etirelli
