| 7 | View Code Duplication | class QueuedTransformer implements TransformerInterface |

| 8 | { |
||
| 9 | private $transformer; |
||
| 10 | private $broker; |
||
| 11 | private $consumer; |
||
| 12 | |||
| 13 | public function __construct(TransformerConsumer $transformer, AmqpBroker $broker, $consumer) |
||

| 20 | public function transform($data = null) |
