| * {@link Codec}s that uses the MIME multipart as the underlying format. |
| * |
| * <p> |
| * When the runtime needs to dynamically choose a {@link Codec}, and |
| * when there are more than one {@link Codec}s that use MIME multipart, |
| * it is often impossible to determine the right {@link Codec} unless |
| * you parse the multipart message to some extent. |
| * |
| * <p> |
| * By having all such {@link Codec}s extending from this class, |
| * the "sniffer" can decode a multipart message partially, and then |
| * pass the partial parse result to the ultimately-responsible {@link Codec}. |
| * This improves the performance. |
