类 DistinctResultTransformer

java.lang.Object

org.hibernate.transform.BasicTransformerAdapter

org.hibernate.transform.DistinctResultTransformer

所有已实现的接口:

Serializable, ResultTransformer

public class DistinctResultTransformer
extends BasicTransformerAdapter

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.
