Class AliasToEntityMapResultTransformer
java.lang.Object
org.hibernate.transform.BasicTransformerAdapter
org.hibernate.transform.AliasedTupleSubsetResultTransformer
org.hibernate.transform.AliasToEntityMapResultTransformer
- All Implemented Interfaces:
- Serializable, ResultTransformer, TupleSubsetResultTransformer
public class AliasToEntityMapResultTransformer
- extends AliasedTupleSubsetResultTransformer
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
.

INSTANCE
public static final AliasToEntityMapResultTransformer INSTANCE
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.
- Specified by:
transformTuple
in interface ResultTransformer
- Overrides:
transformTuple
in class BasicTransformerAdapter
- Parameters:
tuple
- The result elementsaliases
- The result aliases ("parallel" array to tuple)
- Returns:
- The transformed row.
isTransformedValueATupleElement
public boolean isTransformedValueATupleElement(String[] aliases,
int tupleLength)
- When a tuple is transformed, is the result a single element of the tuple?
- Parameters:
aliases
- - the aliases that correspond to the tupletupleLength
- - the number of elements in the tuple
- Returns:
- true, if the transformed value is a single element of the tuple;
false, otherwise.
