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