| <div class="block">Marker annotation for methods which may return <code>java.util.Optional</code> 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 <a href="https://docs.oracle.com/en/java/javase/16/docs/api/java.base/java/util/Optional.html" title="class or interface in java.util" class="external-link"><code>Optional</code></a> 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. |
| |
| <p><b>Note:</b> the use of this annotation is not a guarantee that the annotated method will return |
| <a href="https://docs.oracle.com/en/java/javase/16/docs/api/java.base/java/util/Optional.html" title="class or interface in java.util" class="external-link"><code>Optional</code></a> in SIS 2. It only means that this possibility is under consideration.</p></div> |
