Print MatOfKeyPoint in a text file

Hi guys, At the first, sorry for my bad english. I'm a student and I'm trying to develop an application with the Android version of OpenCV. I need some information about the structure and the methods to manipulate MatOfKeyPoint Object.

I don't understand so good the structure of Keypoints and MatOfKeyPoint, however I need to "print" the MatOfKeyPoints of certain image in a text file but I don't understand how to do it.

Can you explain me what functions can I use to do it?

Here there is the dedicated JavaDoc: Java API
