public @interface NonNull
A common 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 Micronaut API.
Should be used at parameter, return value, and field level. Method overrides should repeat parent @NonNull
annotations unless
they behave differently.
