Class AliasToEntityMapResultTransformer

java.lang.Object

org.hibernate.transform.BasicTransformerAdapter

org.hibernate.transform.AliasToEntityMapResultTransformer

All Implemented Interfaces:

Serializable, ResultTransformer

public class AliasToEntityMapResultTransformer
extends BasicTransformerAdapter
implements Serializable

ResultTransformer implementation which builds a map for each "row", made up of each aliased value where the alias is the map key.

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