All Known Implementing Classes:
AbstractApplicationEventMulticaster, SimpleApplicationEventMulticaster
```
public interface ApplicationEventMulticaster
```
Interface to be implemented by objects that can manage a number of ApplicationListener objects and publish events to them.
An ApplicationEventPublisher, typically a Spring ApplicationContext, can use an ApplicationEventMulticaster as a delegate for actually publishing events.

- Method Detail
  - addApplicationListener
```
void addApplicationListener(ApplicationListener<?> listener)
```
    Add a listener to be notified of all events.
    Parameters:
    listener - the listener to add
  - addApplicationListenerBean
```
void addApplicationListenerBean(String listenerBeanName)
```
    Add a listener bean to be notified of all events.
    Parameters:
    listenerBeanName - the name of the listener bean to add
  - removeApplicationListener
```
void removeApplicationListener(ApplicationListener<?> listener)
```
    Remove a listener from the notification list.
    Parameters:
    listener - the listener to remove
  - removeApplicationListenerBean
```
void removeApplicationListenerBean(String listenerBeanName)
```
    Remove a listener bean from the notification list.
    Parameters:
    listenerBeanName - the name of the listener bean to remove
  - removeAllListeners
```
void removeAllListeners()
```
    Remove all listeners registered with this multicaster.
    After a remove call, the multicaster will perform no action on event notification until new listeners are registered.
  - multicastEvent
```
void multicastEvent(ApplicationEvent event)
```
    Multicast the given application event to appropriate listeners.
    Consider using multicastEvent(ApplicationEvent, ResolvableType) if possible as it provides better support for generics-based events.
    Parameters:
    event - the event to multicast
  - multicastEvent
```
void multicastEvent(ApplicationEvent event,
                    @Nullable
                    ResolvableType eventType)
```
    Multicast the given application event to appropriate listeners.
    If the eventType is null, a default type is built based on the event instance.
    Parameters:
    event - the event to multicast
    eventType - the type of event (can be null)
