set() 공개 메소드

For example, php register a class name as is. This can be skipped. $container->set('yii\db\Connection'); register an interface When a class depends on the interface, the corresponding class will be instantiated as the dependent object $container->set('yii\mail\MailInterface', 'yii\swiftmailer\Mailer'); register an alias name. You can use $container->get('foo') to create an instance of Connection $container->set('foo', 'yii\db\Connection'); register a class with configuration. The configuration will be applied when the class is instantiated by get() $container->set('yii\db\Connection', [ 'dsn' => 'mysql:host=127.0.0.1;dbname=demo', 'username' => 'root', 'password' => '', 'charset' => 'utf8', ]); register an alias name with class configuration In this case, a "class" element is required to specify the class $container->set('db', [ 'class' => 'yii\db\Connection', 'dsn' => 'mysql:host=127.0.0.1;dbname=demo', 'username' => 'root', 'password' => '', 'charset' => 'utf8', ]); register a PHP callable The callable will be executed when $container->get('db') is called $container->set('db', function ($container, $params, $config) { return new \yii\db\Connection($config); }); If a class definition with the same name already exists, it will be overwritten with the new one. You may use Container::has to check if a class definition already exists.

public set ( string $class, mixed $definition = [], array $params = [] )
$class	string	class name, interface name or alias name
$definition	mixed	the definition associated with `$class`. It can be one of the following: - a PHP callable: The callable will be executed when [[get()]] is invoked. The signature of the callable should be `function ($container, $params, $config)`, where `$params` stands for the list of constructor parameters, `$config` the object configuration, and `$container` the container object. The return value of the callable will be returned by [[get()]] as the object instance requested. - a configuration array: the array contains name-value pairs that will be used to initialize the property values of the newly created object when [[get()]] is called. The `class` element stands for the the class of the object to be created. If `class` is not specified, `$class` will be used as the class name. - a string: a class name, an interface name or an alias name.
$params	array	the list of constructor parameters. The parameters will be passed to the class constructor when [[get()]] is called.

    public function set($class, $definition = [], array $params = [])
    {
        $this->_definitions[$class] = $this->normalizeDefinition($class, $definition);
        $this->_params[$class] = $params;
        unset($this->_singletons[$class]);
        return $this;
    }
