It stores the signature of the event and receives a unique signal_index. Use EventSlot<EventType>::instance_count () and:get_instance (index) to compare the stored events of each slot with your incoming events If an Event matches an EventSlot, the Slot will set its assigned signal to 'signaled'. These signals can be watched by FuncSlots. A signal is an object that can emit typed notifications, really values parametrized after the signal class template parameters, and register any number of notification handlers (callables) of compatible argument types to be executed with the values supplied whenever a signal emission happens. In signal-slot parlance this is called connecting a..
