ApplicationEventBus class abstract

Defines the contract for an event multicaster that manages the registration, removal, and dispatching of ApplicationEvents to ApplicationListeners.

Implementations of this interface are responsible for:

Keeping track of registered listeners and listener pods (by name).
Notifying the appropriate listeners when an event is published.
Supporting listener removal by predicate or name.

Example Usage

final multicaster = MyApplicationEventMulticaster();

multicaster.addApplicationListener(MyCustomListener());
multicaster.addApplicationListenerPod('loggingListener');

multicaster.multicastEvent(SomeCustomEvent());
multicaster.removeApplicationListeners((listener) => listener is MyCustomListener);

This interface is typically implemented within the JetLeaf application context to provide event publication support across the system.

Methods

addApplicationListener({ApplicationEventListener<ApplicationEvent>? listener, String? podName}) → Future<void>: Adds an ApplicationListener instance to the event multicaster or use podName to let Jetleaf lazily resolve the listener by pod name and fetch its instance.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
onEvent(ApplicationEvent event) → Future<void>: Broadcasts the given event to all appropriate listeners.
removeAllListeners() → Future<void>: Removes all listeners, both instances and pods, from the multicaster.
removeApplicationListener({ApplicationEventListener<ApplicationEvent>? listener, String? podName}) → Future<void>: Removes a previously registered ApplicationListener instance or use podName to let Jetleaf lazily resolve the listener by pod name and remove its instance.
removeApplicationListeners({Predicate<ApplicationEventListener<ApplicationEvent>>? listener, Predicate<String>? podName}) → Future<void>: Removes all registered ApplicationListener instances that match the provided listener or pods by name that match the provided podName.
toString() → String: A string representation of this object.
