    /**
     * Specifies the relations with which this query should be performed.
     *
     * The parameters to this method can be either one or multiple strings, or a single array of relation names and the
     * optional callbacks to customize the relations.
     *
     * A relation name can refer to a relation defined in {@see modelClass} or a sub-relation that stands for a relation
     * of a related record.
     *
     * For example, `orders.address` means the `address` relation defined in the model class corresponding to the
     * `orders` relation.
     *
     * The following are some usage examples:
     *
     * ```php
     * // Create active query
     * CustomerQuery = new ActiveQuery(Customer::class, $db);
     * // find customers together with their orders and country
     * CustomerQuery->with('orders', 'country')->all();
     * // find customers together with their orders and the orders' shipping address
     * CustomerQuery->with('orders.address')->all();
     * // find customers together with their country and orders of status 1
     * CustomerQuery->with([
     *     'orders' => function (ActiveQuery $query) {
     *         $query->andWhere('status = 1');
     *     },
     *     'country',
     * ])->all();
     * ```
     *
     * You can call `with()` multiple times. Each call will add relations to the existing ones.
     *
     * For example, the following two statements are equivalent:
     *
     * ```php
     * CustomerQuery->with('orders', 'country')->all();
     * CustomerQuery->with('orders')->with('country')->all();
     * ```
     *
     * @param array|string ...$with a list of relation names or relation definitions.
     *
     * @return static the query object itself.
