boost based Publisher/Subscriber framework in C++

CppPubSub

Boost based Publisher/Subscriber framework in C++. One can subscribe for a channel and another can publish the notification on the same channel.

Note: It has dependency on boost. Please download boost library and set the boost path in project settings (CppPubSub.vcxproj). I tested on Windows and MacOS both. Visual Studio project file is available here, for others you have to make project file yourself.

Full sample code is available in Source.cpp.

Usage:

    // you should create a singleton object of NotificationService class, make it accessible throughout your application. 
    INotificationService* pNotificationService = new NotificationService();

    // Subscribe for the event.
    function<NotificationHandler> fnNotificationHandler = bind(&SubscriberClass::NotificationHandlerFunction, this, std::placeholders::_1);
    subscriptionToken = pNotificationService->Subscribe("TEST_CHANEL", fnNotificationHandler);
    
    // Publish event
    NotificationData _data;
    _data["data1"] = "Hello";
    _data["data2"] = "World";
    pNotificationService->Publish("TEST_CHANEL", _data);
    
    // Unsubscribe event.
    pNotificationService->Unsubscribe(subscriptionToken);
