Method Detail

getFieldList

protected java.util.List<java.lang.reflect.Field> getFieldList()

Description copied from class: Structure

Look up all fields in this class and superclasses.

Overrides:

getFieldList in class Structure

Returns:

ordered list of public Field available on this Structure class.

getFieldOrder

protected java.util.List<java.lang.String> getFieldOrder()

Description copied from class: Structure

Returns this Structure's field names in their proper order.
When defining a new Structure you shouldn't override this method, but use Structure.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 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.

Overrides:

getFieldOrder in class Structure

Returns:

ordered list of field names
