use Symfony\Component\DependencyInjection\Definition; $definition = new Definition('MyService'); $definition->setFile('/path/to/MyService.php'); $file = $definition->getFile(); // returns '/path/to/MyService.php'
use Symfony\Component\DependencyInjection\Definition; use Symfony\Component\HttpFoundation\Request; $requestDefinition = new Definition(Request::class); $requestDefinition->setFile((new \ReflectionClass(Request::class))->getFileName()); $file = $requestDefinition->getFile(); // returns '/path/to/Request.php'In this example, we use the `Definition` class to create a definition for the `Request` class from the Symfony `HttpFoundation` component. We retrieve the file path for the `Request` class using the `getFileName` method of the `ReflectionClass` class. This method belongs to the Symfony DependencyInjection Component Library.
