Denotes a method as a field offset access of a RawStructure. The method must not have any parameters. The return type must be a primitive integer type or a word type.

Calls to the method are replaced with a compile time constant. If the annotation is used on a non-static method, the receiver is ignored. Java does not allow an interface method to be declared static native. So the annotated method must either be non-static (with the receiver being ignored), or static but non-native (with the method body being ignored).

Since:19.3
