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.

Parameters
collection The result.
Returns
  • The transformed result.

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.

Parameters
tuple The result elements
aliases The result aliases ("parallel" array to tuple)
Returns
  • The transformed row.
