/**
* By default, types in method signatures that lack a null annotation are regarded as nullable.
* This annotation (with it default value {@code true}) indicates that types in method signatures that lack a null
* annotation are regarded as non-null.
* It is generally good practice to add {@code @NotNullByDefault} to all your package declarations (i.e.
* 'package-into.java' files), because in well-designed code (especially API methods), {@code @NonNull} is
* significantly more frequent than {@code @Nullable}.
