 * In the implementation of this call-back method, you should consider invoking

 * non-trivial field of the {@code src} object. However, you should never invoke it on the
 * {@code src} object itself since that will cause an infinite loop (Gson will call your
 * call-back method again).
 * @param src the object that needs to be converted to Json.
 * @param typeOfSrc the actual type (fully genericized version) of the source object.
