This class is used to post events between threads in the application. It is Thread-Safe and the events are sent to receivers in the same order they are posted (FIFO). It works like the design pattern Mediator. It is also a Singleton, so it can be used anywhere in the application.
To send an event, use UEventsManager::post(). Events are automatically deleted after they are posted.
The EventsManager have a list of handlers to which it sends posted events. To add an handler, use UEventsManager::addHandler(). To remove, use UEventsManager::removeHandler().

This method is used to post an event to handlers.
Event can be posted asynchronously or not. In the first case, the event is dispatched by the UEventsManager's thread. In the second case, the event is handled immediately by event's receivers, thus in the sender thread.
event | the event to be posted. |
async | if true, the event is dispatched by the UEventsManager thread, otherwise it's in the caller thread (synchronous). |
