However, 2) is more portable than 3) because 3) really relies on the framework to know about @inject annotations. I recommend that you use 3) in all of your applications if the portability aspect is not important in your case. I must admit though that we have the policy to use only setter injection in FLOW3 itself due to speed reasons and some other implications.

Less typing:

2)

class MyClass {

   /**
    * @var \F3\FLOW3\Object\FactoryInterface
    */
   protected $objectFactory

   /**
    * Injects the object factory
    *
    * @param \F3\FLOW3\Object\FactoryInterface $objectFactory
    * @return void
    */
   public function injectObjectFactory(\F3\FLOW3\Object\FactoryInterface $objectFactory) {
       $this->objectFactory = $objectFactory;
   }

}

3)

class MyClass {

   /**
    * @inject
    * @var \F3\FLOW3\Object\FactoryInterface
    */
   protected $objectFactory
}

Portability and performance might be better in 2)

yes.

Cheers,
