Annotation Type NonNullApi

@Target(value=PACKAGE)
 @Retention(value=RUNTIME)
 @Documented
 @Nonnull
 @TypeQualifierDefault(value={METHOD,PARAMETER})
public @interface NonNullApi

A common Reactor annotation (similar to Spring one) 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 Reactor API.

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

Since:

3.1.0
