/**
 | 
						|
 * Container implements a [dependency injection](https://en.wikipedia.org/wiki/Dependency_injection) container.
 | 
						|
 *
 | 
						|
 * A dependency injection (DI) container is an object that knows how to instantiate and configure objects and
 | 
						|
 * all their dependent objects. For more information about DI, please refer to
 | 
						|
 * [Martin Fowler's article](https://martinfowler.com/articles/injection.html).
 | 
						|
 *
 | 
						|
 * Container supports constructor injection as well as property injection.
 | 
						|
 *
 | 
						|
 * To use Container, you first need to set up the class dependencies by calling [[set()]].
 | 
						|
 * You then call [[get()]] to create a new class object. The Container will automatically instantiate
 | 
						|
 * dependent objects, inject them into the object being created, configure, and finally return the newly created object.
 | 
						|
 *
 | 
						|
 * By default, [[\Yii::$container]] refers to a Container instance which is used by [[\Yii::createObject()]]
 | 
						|
 * to create new object instances. You may use this method to replace the `new` operator
 | 
						|
 * when creating a new object, which gives you the benefit of automatic dependency resolution and default
 | 
						|
 * property configuration.
 | 
						|
 *
 | 
						|
 * Below is an example of using Container:
 | 
						|
 *
 | 
						|
 * ```php
 | 
						|
 * namespace app\models;
 | 
						|
 *
 | 
						|
 * use yii\base\BaseObject;
 | 
						|
 * use yii\db\Connection;
 | 
						|
 * use yii\di\Container;
 | 
						|
 *
 | 
						|
 * interface UserFinderInterface
 | 
						|
 * {
 | 
						|
 *     function findUser();
 | 
						|
 * }
 | 
						|
 *
 | 
						|
 * class UserFinder extends BaseObject implements UserFinderInterface
 | 
						|
 * {
 | 
						|
 *     public $db;
 | 
						|
 *
 | 
						|
 *     public function __construct(Connection $db, $config = [])
 | 
						|
 *     {
 | 
						|
 *         $this->db = $db;
 | 
						|
 *         parent::__construct($config);
 | 
						|
 *     }
 | 
						|
 *
 | 
						|
 *     public function findUser()
 | 
						|
 *     {
 | 
						|

 | 
						|
 * }
 | 
						|
 *

						|

 |

 | 
						|
 *     {
 | 
						|
 *         $this->finder = $finder;
 | 
						|
 *         parent::__construct($config);
 | 
						|
 *     }
 | 
						|
 * }
 | 
						|
 *
 | 
						|
 * $container = new Container;
 | 
						|
 * $container->set('yii\db\Connection', [
 | 
						|
 *     'dsn' => '...',
 | 
						|
 * ]);
 | 
						|
 * $container->set('app\models\UserFinderInterface', [
 | 
						|
 *     'class' => 'app\models\UserFinder',
 | 
						|
 * ]);
 | 
						|
 * $container->set('userLister', 'app\models\UserLister');
 | 
						|
 *
 | 
						|
 * $lister = $container->get('userLister');
 | 
						|
 *
 | 
						|
 * // which is equivalent to:
 | 
						|
 *
 | 
						|
 * $db = new \yii\db\Connection(['dsn' => '...']);
 | 
						|
 * $finder = new UserFinder($db);
 | 
						|
 * $lister = new UserLister($finder);
 | 
						|
 * ```
 | 
						|
 *
 | 
						|
 * For more details and usage information on Container, see the [guide article on di-containers](guide:concept-di-container).

 | 
						|
     *
 |

     * @param array $definitions array of definitions. There are two allowed formats of array.
 | 
						|
     * The first format:
 | 
						|
     *  - key: class name, interface name or alias name. The key will be passed to the [[set()]] method
 | 
						|
     *    as a first argument `$class`.
 | 
						|
     *  - value: the definition associated with `$class`. Possible values are described in
 | 
						|
     *    [[set()]] documentation for the `$definition` parameter. Will be passed to the [[set()]] method
 | 
						|
     *    as the second argument `$definition`.
 | 
						|
     *
 | 
						|
     * Example:
 | 
						|
     * ```php
 | 
						|
     * $container->setDefinitions([
 | 
						|
     *     'yii\web\Request' => 'app\components\Request',
 | 
						|
     *     'yii\web\Response' => [
 | 
						|
     *         'class' => 'app\components\Response',
 | 
						|
     *         'format' => 'json'
 | 
						|
     *     ],
 | 
						|
     *     'foo\Bar' => function () {
 | 
						|
     *         $qux = new Qux;
 | 
						|
     *         $foo = new Foo($qux);
 |

     *         return new Bar($foo);
 | 
						|
     *     }
 | 
						|
     * ]);
 | 
						|
     * ```
 | 
						|
     *
 | 
						|
     * The second format:
 | 
						|
     *  - key: class name, interface name or alias name. The key will be passed to the [[set()]] method
 | 
						|
     *    as a first argument `$class`.
 | 
						|
     *  - value: array of two elements. The first element will be passed the [[set()]] method as the
 | 
						|
     *    second argument `$definition`, the second one — as `$params`.
 | 
						|
     *
 | 
						|
     * Example:
 | 
						|
     * ```php
 | 
						|
     * $container->setDefinitions([
 | 
						|
     *     'foo\Bar' => [
 | 
						|
     *          ['class' => 'app\Bar'],

						|
     *      ]
 | 
						|
     * ]);
 | 
						|
     * ```
