public class: AliasToEntityMapResultTransformer [javadoc | source]

java.lang.Object

      org.hibernate.transform.AliasToEntityMapResultTransformer

All Implemented Interfaces:
Serializable, ResultTransformer

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