YSignalSlot is a header only C++ library. It is an implementation of signal-slot mechanism via C++. It is similar to C++ signal, Boost::signal and SigSlot. It intensively uses C++11 features.
Advantages:
- Almost everything is compile-time. So it is fast.
- It can be used with single slot function or unlimited slot functions.
- “emit” function’s return type is pointer of your actual slot function’s return type and it can be any type.
- It supports “void” return type.
- Slot(s) can be set to enable or disable. If slot(s) is/are disabled, signal can’t emit this/these slot(s).
- If slot which emitted is disabled or its return type is void, “emit” function returns “NULL” pointer.
- It works with member slot functions.
- It uses meta programming methods for “static for loop” and “static if”.
- Signals can be used nested.
- Receivers can be “this” pointer.
- It is free and LGPL licensed.
- It uses C++11 features.
