Inter Component Communication

This is a library created to simplify communication between components inside of single application. It is thread safe and could be used for creating components that works in different threads.

Integration

To integrate this library in your project you just need in CMake add: add_subdirectory(<path_to_library>)

Usage

Active Object example

Here is simple example of WeatherStationService and DisplayService that works in different threads:

#include <icc/Component.hpp>

class WeatherStationService : public icc::Component {
 public:
   icc::Event<void(const double &)> temperature_;

 private:
   void handleTemperature() {
     ...
     temperature_(28.3);
     ...
   }
};

class DisplayService : public icc::Component {
 public:
  explicit DisplayService(WeatherStationService& station) {
    station.temperature_.connect(&DisplayService::onTemperature, this);
  }

  void onTemperature(const double & _temperature) {
     std::cout << "DisplayService::Temperature is " << _temperature << std::endl;
   }
};

int main() {
   auto observer = std::make_shared<WeatherObserver>();
   auto station = std::make_shared<WeatherStation>(*observer);
   auto observerThread = std::thread([&observer] {
     observer->exec();
   });
   auto stationThread = std::thread([&station] {
     station->exec();
   });
   observerThread.join();
   stationThread.join();
}

Known issues

1. Some compilers that supports C++17 at the same time does not support Feature Macros __cpp_lib_optional If you want to use automatic conversion from icc::_private::containers::Optional to C++17 std::optional you should set this macros by hand like this:

   add_definitions(-D__cpp_lib_optional=201606)
