This class is a clone of org.springframework.lang.NonNull
A common Aspectran annotation 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 Aspectran API.
Should be used at parameter, return value, and field level. Method overrides should repeat parent @NonNull annotations unless they behave differently.
Use @NonNullApi (scope = parameters + return values) and/or @NonNullFields (scope = fields) to set the default behavior to non-nullable in order to avoid annotating your whole codebase with @NonNull.
