/**
 * Pagination represents information relevant to pagination of data items.
 *
 * When data needs to be rendered in multiple pages, Pagination can be used to
 * represent information such as [[totalCount|total item count]], [[pageSize|page size]],
 * [[page|current page]], etc. These information can be passed to [[\yii\widgets\LinkPager|pagers]]
 * to render pagination buttons or links.
 *
 * The following example shows how to create a pagination object and feed it
 * to a pager.
 *
 * Controller action:
 *
 * ```php
 * public function actionIndex()
 * {
 *     $query = Article::find()->where(['status' => 1]);
 *     $countQuery = clone $query;
 *     $pages = new Pagination(['totalCount' => $countQuery->count()]);
 *     $models = $query->offset($pages->offset)
 *         ->limit($pages->limit)
 *         ->all();
 *
 *     return $this->render('index', [
 *          'models' => $models,
 *          'pages' => $pages,
 *     ]);
 * }
 * ```
 *
 * View:
 *
 * ```php
 * foreach ($models as $model) {
 *     // display $model here
 * }
 *
 * // display pagination
 * echo LinkPager::widget([
 *     'pagination' => $pages,
 * ]);
 * ```
 *
 * For more details and usage information on Pagination, see the [guide article on pagination](guide:output-pagination).
 *
 * @property-read int $limit The limit of the data. This may be used to set the LIMIT value for a SQL
 * statement for fetching the current page of data. Note that if the page size is infinite, a value -1 will be
 * returned.
 * @property-read array $links The links for navigational purpose. The array keys specify the purpose of the
 * links (e.g. [[LINK_FIRST]]), and the array values are the corresponding URLs.
 * @property-read int $offset The offset of the data. This may be used to set the OFFSET value for a SQL
 * statement for fetching the current page of data.
 * @property int $page The zero-based current page number.
 * @property-read int $pageCount Number of pages.
 * @property int $pageSize The number of items per page. If it is less than 1, it means the page size is
 * infinite, and thus a single page contains all items.
 * @property int $totalCount total number of items.
