public interface ChainedObserverThe marker interface implemented by all statistic observer classes.A statistic observer presents methods used to update a statistic. There are two general classes of observer implementations:
- Initial observers are called by product code in order to record the occurrence of a product related 'event'
- Derived observers are called by other observers with then intention of tracking higher order statistics.
