Hibernate Core 3.6.10.Final · org.hibernate.transform.DistinctRootEntityResultTransformer

Much like RootEntityResultTransformer, but we also distinct the entity in the final result.

Since this transformer is stateless, all instances would be considered equal. So for optimization purposes we limit it to a single, singleton instance.
