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