 * <ol>
 *    <li>PRE_PROCESSING: where the input data is first processed by the
 *    current {@link Transformer} before being passed to the rest of the chain;
 *    and</li>
 *    <li>POST_PROCESSING: where the input data is first passed to the rest of
 *    the chain, and the resulting bytes are then processed by the current
