Spring MVC: @ResponseBody Get method return void

I have a controller method which should return some data. I'm wondering why despite it's GET and marked with @ResponseBody it's void.

@ResponseBody    
@RequestMapping(value = "/{id}/data", method = GET)
public void getData(....) { // < Question: how it can be void?
  ....
  dataService.streamData(query); // < this method is also void
}

Question: What spring returns in this case? Is this method useless?

If a controller returns a null view name, or declares a void return type, Spring will attempt to infer the view name from the request URL.

It does this using an implementation of RequestToViewNameTranslator, the default implementation of which is DefaultRequestToViewNameTranslator
