protected List<String> getFieldOrder() Overrides com.sun.jna.Structure.getFieldOrder. Doc from com.sun.jna.Structure.getFieldOrder. Returns this Structure's field names in their proper order. When defining a new `Structure` you shouldn't override this method, but use `FieldOrder` annotation to define your field order(this also works with inheritance) If you want to do something non-standard you can override the method and define it as followed `protected List getFieldOrder() { return Arrays.asList(...); }` Important Note When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g. `protected List getFieldOrder() { List fields = new LinkedList(super.getFieldOrder()); fields.addAll(Arrays.asList(...)); return fields; }` Field order must be explicitly indicated, since the field order as returned by `Class#getFields()` is not guaranteed to be predictable.
