 Usage is quite simple also:
 
 ```php
-/**
- * @param SequenceNumberGenerator $sequenceNumberGenerator

-public function __construct(SequenceNumberGenerator $sequenceNumberGenerator)

+    }
 ```
 
 `getNextNumberFor` allows you to give an object (which will be resolved to its FQCN) or a custom sequence name.
