Chapter 67. Boost.Signals2 - Boris Schäling Boost.Signals2 implements the signal/slot concept. One or multiple functions – called slots – are linked with an object that can emit a signal. Every time the signal is emitted, the linked functions are called. A lightweight C++ signals and slots implementation | Hacker News Why it's interesting alternative: regular observer pattern make observed code depend (at compile time) on the observing code. Signals/slots remove this dependency, and allow for external configuration of these. It's a dependency injection mechanism when you think about it. c++ - Observer pattern; knowing *what* changed? - Software ... For observer pattern, it is important that Arg data type is not hard coded between the observee and observer - else it is a coupling that makes things difficult to evolve. EDIT If you want that observer not only observes but also needs to do a lot of other tasks based on the what has changed then, you can also check out Visitor pattern .
