Method Detail

processRow

T processRow(ResultSet resultSet,
             int rowOffset)
             throws TorqueException

Constructs the object from the current row in the resultSet. Implementing methods can be sure that the resultSet contains a row, but they must only operate on the current row, i.e they must not call resultSet.next().

Parameters:

resultSet - the resultSet to operate on, already pointing to the correct row. Not null.

rowOffset - a possible offset in the rows to be considered (if previous rows contain other objects).

Returns:

the mapped object, not null.

Throws:

TorqueException - when the mapping fails.
