Method Summary
Modifier and TypeMethodDescriptionLook up all fields in this class and superclasses.Returns this Structure's field names in their proper order.
When defining a newStructureyou shouldn't override this method, but useStructure.FieldOrderannotation 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 followedMethods inherited from class com.sun.jna.Structure

getFieldList
Description copied from class:StructureLook up all fields in this class and superclasses.- Overrides:
getFieldListin classStructure- Returns:
- ordered list of public
Fieldavailable on thisStructureclass.
-
getFieldOrder
Description copied from class:StructureReturns this Structure's field names in their proper order.
When defining a newStructureyou shouldn't override this method, but useStructure.FieldOrderannotation 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
IMPORTANT When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g.protected ListgetFieldOrder() { return Arrays.asList(...); }
Field order must be explicitly indicated, since the field order as returned byprotected ListgetFieldOrder() { List fields = new LinkedList (super.getFieldOrder()); fields.addAll(Arrays.asList(...)); return fields; } Class.getFields()is not guaranteed to be predictable.- Overrides:
getFieldOrderin classStructure- Returns:
- ordered list of field names
