Annotation Type NonNullApi



  • @Target(value=PACKAGE)
     @Retention(value=RUNTIME)

     @Nonnull
     @TypeQualifierDefault(value={METHOD,PARAMETER})
    public @interface NonNullApi
    A common Spring annotation to declare that parameters and return values are to be considered as non-nullable by default for a given package.

    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 Spring API.

    Should be used at package level in association with Nullable annotations at parameter and return value level.
