public Class AliasToEntityMapResultTransformer

extends BasicTransformerAdapter
implements Serializable
Class Inheritance
All Implemented Interfaces

Imports
java.util.HashMap, .Map, java.io.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.

Doc from org.hibernate.transform.ResultTransformer.transformTuple.

Tuples are the elements making up each "row" of the query result. The contract here is to transform these elements into the final row.

Parameters
tuple:Object[]

The result elements

aliases:String[]

The result aliases ("parallel" array to tuple)

Returns:Object

The transformed row.
