Annotation Interface OptionalCandidate

@Documented @Target(METHOD) @Retention(SOURCE) public @interface OptionalCandidate
Marker annotation for methods which may return java.util.Optional in a future version. This is applied on some methods introduced at a time when Apache SIS was targeting Java 6 or 7. Replacing the return value by an Optional would be an incompatible change, so this change will not be applied in SIS 1.x. But it may be applied in SIS 2.0.

Note: the use of this annotation is not a guarantee that the annotated method will return Optional in SIS 2. It only means that this possibility is under consideration.
