Android Camera2: How to use SENSOR_BLACK_LEVEL_PATTERN API?

Question

In Camera2, I found one API called SENSOR_BLACK_LEVEL_PATTERN. I am trying to get information of my device related to this API. Somehow I don't understand how to get it. I have done it upto here:

CameraCharacteristics mCameraCharacteristics = manager.getCameraCharacteristics(cameraId);

BlackLevelPattern blackLevelPattern = mCameraCharacteristics.get(CameraCharacteristics.SENSOR_BLACK_LEVEL_PATTERN);

//What to do next with  blackLevelPattern?

Want to use getOffsetForIndex() method.

UPDATE: Is this fine to use like this: blackLevelPattern.getOffsetForIndex(0, 0)

Please suggest. thanks in advance.

Finally I am able to do it using below code:

CameraCharacteristics mCameraCharacteristics = manager.getCameraCharacteristics(cameraId);                                
BlackLevelPattern blackLevelPattern = mCameraCharacteristics.get(CameraCharacteristics.SENSOR_BLACK_LEVEL_PATTERN);
                                int[][] array = new int[2][2];
                                for (int c = 0; c < array.length; c++) {
                                    for (int r = 0; r < array.length; r++) {
                                        append(blackLevelPattern.getOffsetForIndex(c, r);

                                        }
                                    }
