| 25 |  /** | |
| 26 |   * A LucidException adds 2 concepts to a base Exception, that of a wrapped | |
| 27 |   * Exception, that of internationalized (i18n) messages. | |
| 28 |   *  | |
| 29 |   * <p> | |
| 30 |   * The first addition is the concept of an optional wrapped Exception (actually | |
| 31 |   * a Throwable), which describes what caused this to happen. Any well defined | |
| 32 |   * interface will define the exact exceptions that the methods of that interface | |
| 33 |   * will throw, and not leave it to the ambiguous "throws Exception". However the | |
| 34 |   * interface should have no idea how it will be implemented and so the details | |
| 35 |   * of exactly what broke under the covers gets lost. With LucidException this | |
| 36 |   * detail is kept in the wrapped Exception. This functionality has been added to | |
| 37 |   * the base Exception class in J2SE 1.4 | |
| 38 |   * </p> | |
| 39 |   *  | |
| 40 |   * <p> | |
| 41 |   * The second addition is the concept of i18n messages. Normal Exceptions are | |
| 42 |   * created with an almost random string in the message field, LucidExceptions | |
| 43 |   * define this string to be a key into a resource bundle, and to help formatting | |
| 44 |   * this string there is an optional Object array of format options. There is a | |
| 45 |   * constructor that allows us to specify no i18n lookup, which is useful if this | |
| 46 |   * lookup may have been done already. | |
| 47 |   * </p> | |
