public interface ResultTransformer
extends Serializable
Implementors define a strategy for transforming query results into the
actual application-visible query result list.
List | transformList(List collection) - Here we have an opportunity to perform transformation on the
query result as a whole.
|
Object | transformTuple(Object[] tuple, String[] aliases) - Tuples are the elements making up each "row" of the query result.

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.
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.
tuple
- The result elementsaliases
- The result aliases ("parallel" array to tuple)
