| * <dt>Interaction with inheritance</dt> |
| * <dd>This annotation has lower precedence than null contract inheritance, |
| * i.e., for a method with no explicit null annotations first inheritance |
| * from the super-method (overridden or implemented) are considered. |
| * Only if that search yields no null annotation the default defined using |
| * <code>@NonNullByDefault</code> is applied.</dd> |
| * <dt>Nested defaults</dt> |
| * <dd>If a <code>@NonNullByDefault</code> |
| * annotation is used within the scope of a <code>@NullableByDefault</code> |
| * annotation the inner most annotation defines the default applicable at |
| * any given position.</dd> |
| * </dl> |
| * Note that for applying an annotation to a package a file by the name |
| * <code>package-info.java</code> is used. |
