getFieldOrder
protected List<String> getFieldOrder()
Description copied from class:Structure
Return this Structure's field names in their proper order. For example,
IMPORTANT When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g.protected List getFieldOrder() { return Arrays.asList(new String[] { ... }); }
Field order must be explicitly indicated, since the field order as returned byprotected List getFieldOrder() { List fields = new ArrayList(super.getFieldOrder()); fields.addAll(Arrays.asList(new String[] { ... })); return fields; }
Class.getFields()
is not guaranteed to be predictable.- Overrides:

- Returns:
