Annotation Type Nullable


  • @Target({METHOD,PARAMETER,FIELD})
    @Retention(RUNTIME)
    @Documented
    public @interface Nullable
    A common annotation to declare that annotated elements can be null 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 the 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. ForgeRock changes: -Remove @Nonnull and @TypeQualifierNickname to remove external dependency on Findbugs
