  `Serializable`

All Known Implementing Classes:
  `BigDecimalMapper`, `CompositeMapper`, `DateMapper`, `IntegerMapper`, `LongMapper`, `ObjectListMapper`, `StringMapper`

Functional Interface:
  This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

- ## Method Details

  - ### processRow

    T processRow(ResultSet resultSet, int rowOffset, Criteria criteria) 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 columns to be considered (if previous columns contain other objects), or 0 for no offset.
      `criteria` - the Criteria which contains the query to process, or null if not known or the query was not produced by a Criteria. Can be used by the RecordMapper to determine the columns contained in the result set.
    Returns:
      the mapped object, not null.
    Throws:
      `TorqueException` - when the mapping fails.
