@Documented @Retention(RUNTIME) @Target({METHOD,PARAMETER,FIELD}) @Nonnull(when=MAYBE) @TypeQualifierNickname public @interface Nullable
This class is a clone of org.springframework.lang.Nullable
A common Aspectran annotation to declare that annotated elements can benull
under some circumstance.Leverages JSR-305 meta-annotations to indicate nullability in Java to common tools with JSR-305 support and used by Kotlin to infer nullability of Aspectran API.
Should be used at parameter, return value, and field level. Methods override should repeat parent
@Nullable
annotations unless they behave differently.Can be used in association with
@NonNullApi
or@NonNullFields
to override the default non-nullable semantic to nullable.- Since:
