EventBus class - event_arch library

Constructors

EventBus({bool isModelBus = false}): Factory constructor for EventBus. Creates an EventBusImpl instance.
factory

allEventStream → Stream<(EventDTO, bool)>: Stream for all sent events (event DTO, and whether it had a listener or not)
no setter
handlers → EventBusHandlers: Handler management without casting bus as EventBusHandlers.
no setter
hashCode → int: The hash code for this object.
no setterinherited
isDisposed → bool: true once dispose has been called
no setter
isModelBus → bool: no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

dispose() → Future<void>: Closes the all-events stream and every node of the bus. Safe to call twice. After dispose the bus is unusable: send/listen/subscribe/setHandler throw StateError.
haveHandler<T>({String? path, String? target}) → bool: Returns true if the bus contains a handler for the specified topic
haveListener<T>({String? path, String? target}) → bool: Returns true if the bus contains a listener for the specified topic
lastData<T>({String? path, String? target}) → T?: Gets the last data sent to a specific topic.
listen<T>({String? path, String? target}) → Stream<T>: Listens to events on a specific topic. Returns a Stream of the data type T.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.

send<T>(T data, {String? path, String? fragment, String? target, Map<String, String>? arguments}) → Future?: Sends an event to the bus. If a handler exists for the topic, it will be called. Returns a Future that completes with the result if EventDTO.completer was called by the handler.
subscribe<T>({String? path, String? target, void onData(T e)?, Function? onError, void onDone()?, bool? cancelOnError}) → StreamSubscription<T>: Subscribe to events on a specific topic.
toString() → String: A string representation of this object.
