### Java: Hot to set parameters to ORB FeatureDetector?

As it say documentation, in OpenCV there is a constructor called ORB, where I can specify a lot of parameters. But I'm using Java and I can't find how to specify those parameters. All I can to is to initialize detector with:

FeatureDetector detector = FeatureDetector.create(FeatureDetector.ORB);


So how I can specify parameters from documentation? Is there another way to initialize ORB feature detector in Java? Thanks.
