the class Transformation method transform.

 * @param exportJob the export job
 * @param validationJob the validation job, may be <code>null</code>
 * @param alignment the alignment, may not be changed outside this method
 * @param sourceSchema the source schema
 * @param reportHandler the report handler
 * @param serviceProvider the service provider in the transformation context
 * @param processId the identifier for the transformation process, may be
 *            <code>null</code> if grouping the jobs to a job family is not
 *            necessary
 * @return the future representing the successful completion of the
 *         transformation (note that a successful completion doesn't
 *         necessary mean there weren't any internal transformation errors)
