• results in rich domain models /**

• provides a common language protected $title;
across the project team /**

41. Object Management
FLOW3's take on Dependency Injection
• one of the first PHP implementations
(started in 2006, improved ever since)
• object management for the whole lifecycle of all objects
• no unnecessary configuration if information can be
gatered automatically (autowiring)
• intuitive use and no bad magical surprises
• fast! (like hardcoded or faster)

42. Constructor Injection
namespace AcmeDemoController;
use TYPO3FLOW3MvcControllerActionController;
use AcmeDemoServiceGreeterService;
class DemoController extends ActionController {
/**
* @var AcmeDemoServiceGreeterService
*/
protected $greeterService;
/**
* @param AcmeDemoServiceGreeterService
*/
public function __construct(GreeterService $greeterService) {
$this->greeterService = $greeterService;
}
/**
* @param string $name
*/
public function helloAction($name) {
return $this->greeterService->greet($name);
}
}

43. Setter Injection
namespace AcmeDemoController;
use TYPO3FLOW3MVCControllerActionController;
use AcmeDemoServiceGreeterService;
class DemoController extends ActionController {
/**
* @var AcmeDemoServiceGreeterService
*/
protected $greeterService;
/**
* @param AcmeDemoServiceGreeterService
*/
public function injectGreeterService(GreeterService $greeterService) {
$this->greeterService = $greeterService;
}
/**
* @param string $name
*/
public function helloAction($name) {
return $this->greeterService->greet($name);
}
}

44. Property Injection
namespace TYPO3DemoController;
use TYPO3FLOW3Annotations as FLOW3;
use TYPO3FLOW3MVCControllerActionController;
use AcmeDemoServiceGreeterService;
class DemoController extends ActionController {
/**
* @var TYPO3DemoServiceGreeterService
* @FLOW3Inject
*/
protected $greeterService;
/**
* @param string $name
*/
public function helloAction($name) {
return $this->greeterService->greet($name);
}
}
