This code mostly hard to explain
You may treat this like a factory-class

But you cannot put JNI functions inside a class, that's why it is not a real class

The only thing you need from here - functions JniCreateDataFromFile and JniCreateDataFromAlignedFile for FileUtils.h/cpp

See doc for details
