Class AliasToEntityMapResultTransformer

java.lang.Object
  org.hibernate.transform.BasicTransformerAdapter
      org.hibernate.transform.AliasToEntityMapResultTransformer

All Implemented Interfaces:

ResultTransformer, Serializable

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.
