Hi all,
the README contains a short explanation of the method signature hackery.
Where can I get an overview of what options I have here (which
abbreviation for which type)? I've seen the @c and also @v (void?). When
is it necessary to add a signature and when is it not? I couldn't find
anything about that...
Any small hint is highly appreciated. Thanks a lot in advance!
Kind regards,
- Carsten
