方法详细资料

transformTuple

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.

参数:

tuple - The result elements

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

返回:

The transformed row.

transformList

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.

参数:

collection - The result.

返回:

The transformed result.
