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

Parameters:

tuple - The result elements

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

Returns:

The transformed row.

transformList in interface ResultTransformer

Parameters:

list - The result.

Returns:

The transformed result.
