public class: DistinctRootEntityResultTransformer [javadoc | source]

java.lang.Object
   org.hibernate.transform.DistinctRootEntityResultTransformer

All Implemented Interfaces:
ResultTransformer, Serializable

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 (this is not quite true yet: see deprecation notice on constructor ).

Method from org.hibernate.transform.DistinctRootEntityResultTransformer Detail:
public boolean equals(Object other) { // todo : we can remove this once the deprecated ctor can be made private... return other != null && DistinctRootEntityResultTransformer.class.isInstance( other ); }
public int hashCode() { // todo : we can remove this once the deprecated ctor can be made private... return DistinctRootEntityResultTransformer.class.getName().hashCode(); }
public List transformList(List list) { return DistinctResultTransformer.INSTANCE.transformList( list ); } Simply delegates to DistinctResultTransformer#transformList .
public Object transformTuple(Object[] tuple, String[] aliases) { return RootEntityResultTransformer.INSTANCE.transformTuple( tuple, aliases ); } Simply delegates to RootEntityResultTransformer#transformTuple .
