Class DistinctResultTransformer
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
.
