struct EventSystem : public CE::State::Singleton<EventSystem>

Global access to the default persistent event bus.

Independent owned buses may isolate a subsystem or application lifecycle; all buses use immediate producer-thread delivery unless explicitly adapted.

Public Types

using Callback = ::CE::Events::EventBus::Callback

using Registration = ::CE::Events::EventBus::Registration

using Delivery = ::CE::Events::EventBus::Delivery

using ErrorHandler = ::CE::Events::EventBus::ErrorHandler
