Annotation Interface NonNullApi

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

A common 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 the API.

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