transformTuple

public java.lang.Object transformTuple(java.lang.Object[] tuple,
                                       java.lang.String[] aliases)

Description copied from interface: ResultTransformer

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 elements

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

Returns:

The transformed row.

isTransformedValueATupleElement

public boolean isTransformedValueATupleElement(java.lang.String[] aliases,
                                               int tupleLength)

Description copied from interface: TupleSubsetResultTransformer

When a tuple is transformed, is the result a single element of the tuple?

Specified by:

isTransformedValueATupleElement in interface TupleSubsetResultTransformer

Parameters:

aliases - - the aliases that correspond to the tuple

tupleLength - - the number of elements in the tuple

Returns:

true, if the transformed value is a single element of the tuple; false, otherwise.

includeInTransform

public boolean[] includeInTransform(java.lang.String[] aliases,
                                    int tupleLength)

Description copied from interface: TupleSubsetResultTransformer

Returns an array with the i-th element indicating whether the i-th element of the tuple is included in the transformed value.

Specified by:

includeInTransform in interface TupleSubsetResultTransformer

Parameters:

aliases - - the aliases that correspond to the tuple

tupleLength - - the number of elements in the tuple

Returns:

array with the i-th element indicating whether the i-th element of the tuple is included in the transformed value.
