Event Bus

Event bus facility to help decouple communication between modules,class,etc.

Getting Started

Since is header only,just include EventBus.hpp your project.

1) Define your events

struct DataReceivedEvent{/*Add context here*/};
struct DataTransmittedEvent{/*Add context here*/};

2) Define your handlers

void CommIf::onReceived(DataReceivedEvent ev){/*Process event here*/}
void CommIf::onTransmitted(DataTransmittedEvent ev){/*Process event here*/}

3) Register events to bus with handlers

auto& bus = event_bus::EventBus::getInstance();
CommIf comm{/* */};

bus.registerEvent<DataReceivedEvent>(std::bind(&CommIf::onReceived, &comm std::placeholders::_1));
bus.registerEvent<DataTransmittedEvent>(std::bind(&CommIf::onTransmitted, &comm std::placeholders::_1));

4) Fire events whenever you want to signal listener.

auto& bus = event_bus::EventBus::getInstance();

bus.fireEvent(DataReceivedEvent{/**/});
bus.fireEvent(DataTransmittedEvent{/**/});

Prerequisites
