org.hibernate.transform.AliasToBeanResultTransformer
- ResultTransformer, Serializable
public class AliasToBeanResultTransformer
extends java.lang.Object
Result transformer that allows to transform a result to
a user specified class which will be populated via setter
methods or fields matching the alias names.
List resultWithAliasedBean = s.createCriteria(Enrolment.class)
.createAlias("student", "st")
.createAlias("course", "co")
.setProjection( Projections.projectionList()
.add( Projections.property("co.description"), "courseDescription" )
)
.setResultTransformer( new AliasToBeanResultTransformer(StudentDTO.class) )
.list();
StudentDTO dto = (StudentDTO)resultWithAliasedBean.get(0);

transformList
public List transformList(List collection)
Here we have an opportunity to perform transformation on the
query result as a whole. This might be useful to convert from
one collection type to another or to remove duplicates from the
result, etc.
- transformList in interface ResultTransformer
transformTuple
public Object transformTuple(Object[] tuple,
String[] aliases)
Tuples are the elements making up each "row" of the query result.
The contract here is to transform these elements into the final
row.
