java.lang.Object
- org.hibernate.transform.BasicTransformerAdapter
- - org.hibernate.transform.DistinctResultTransformer

All Implemented Interfaces:

Serializable, ResultTransformer
```
public class DistinctResultTransformer
extends BasicTransformerAdapter
implements Serializable
```
Distinctions the result tuples in the final result based on the defined equality of the tuples.
Since this transformer is stateless, all instances would be considered equal. So for optimization purposes we limit it to a single, singleton instance.
