IEventManager (JDA 4.4.1_353 API)

All Known Implementing Classes:

AnnotatedEventManager, InterfacedEventManager
```
public interface IEventManager
```
An interface for JDA's EventManager system.
This should be registered in the JDABuilder
JDA provides 2 implementations:
- InterfacedEventManager
  Simple implementation that allows EventListener instances as listeners.
- AnnotatedEventManager
  An implementation that accepts any object and uses the SubscribeEvent annotation to handle events.
The default event manager is InterfacedEventManager
Use JDABuilder.setEventManager(IEventManager) to set the preferred event manager implementation.
You can only use one implementation per JDA instance!
