     * Declare here the interface's methods.                                  *
     * They should be:                                                        *
     *   + Methods with the same name of the C component's virtual table      *
     *     (and extended virtual table, if any)'s functions, provided that    *
     *     the component's driver implements them (i.e.: the corresponding    *
     *     pointer to function is not "0").                                   *
