public @interface NonNull
Deprecated.
A common Reactor annotation (similar to Spring ones) to declare that annotated elements
cannot be
null. 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
Reactor API.
Should be used at parameter, return value, and field level.
Methods overrides should repeat parent @NonNull annotations unless they behave
differently.
Use @NonNullApi (scope = parameters + return values) to set the default
behavior to non-nullable in order to avoid annotating your whole codebase with
@NonNull.
