/**
* This annotation can be applied to a package, class or method to indicate that
* the method parameters in that element are nullable 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 applied to a more tightly nested element.
*
* This annotation implies the same "nullness" as no annotation. However, it is different
* than having no annotation, as it is inherited and it can override a {@link ParametersAreNonnullByDefault}
* annotation at an outer scope.
*
* @see Nullable
