Hibernate includes:

- a Statistics interface (org.hibernate.stat.Statistics) and
- a StatisticImplementor interface (org.hibernate.stat.spi.StatisticsImplementor) that extends the first interface, and
- a StatisticImpl class (org.hibernate.stat.internal.StatisticsImpl) that implements StatisticsImplementor

If I want to use a custom implementation of the interface StatisticsImplementor, how can I get Hibernate to use instances of that class?

Is there some Factory I override to produce my customized StatisticImpl? Or some configuration field where I giveits fully qualified class name?

My goal is for Hibernate to use my custom class anywhere it would currently use the out-of-the-box StatisticImpl.

Thanks,  
Tom

You want to actually provide Hibernate an instance that implements the the `StatisticsFactory` in the configuration under the key `hibernate.stats.factory`. By doing that, Hibernate will use your custom factory to create the statistics object rather than the default behavior of instantiating a `StatisticsImpl`.
