This annotation can be applied to a package, class or method to indicate that the method parameters in that element are nonnull by default unless there is:
  • An explicit nullness annotation
  • The method overrides a method in a superclass (in which case the annotation of the corresponding parameter in the superclass applies)
  • There is a default parameter annotation (like ParametersAreNullableByDefault) applied to a more tightly nested element.
