/**
 * ActiveDataProvider implements a data provider based on {@see \Yiisoft\Db\Querys\Query} and
 * {@see \Yiisoft\ActiveRecord\ActiveQuery}.
 *
 * ActiveDataProvider provides data by performing DB queries using {@see query}.
 *
 * The following is an example of using ActiveDataProvider to provide ActiveRecord instances:
 *
 * ```php
 * $provider = new ActiveDataProvider(
 *      Post::find()
 * );
 *
 * $provider->pagination' => [
 *     'pageSize' => 20,
 * ];
 *
 *
 * // get the posts in the current page
 * $posts = $provider->getModels(); // or $provider->models
 * ```
 *
 * And the following example shows how to use ActiveDataProvider without ActiveRecord:
 *
 * ```php
 * $query = new Query();
 * $provider = new ActiveDataProvider(
 *     Yii::get('db'),
 *     $query->from('post')
 * );
 * $provider->pagination' => [
 *     'pageSize' => 20,
 * ];
 *
 *
 * // get the posts in the current page
 * $posts = $provider->getModels();  // or $provider->models
 * ```
 *
 * For more details and usage information on ActiveDataProvider, see the
 * [guide article on data providers](guide:output-data-providers).
