EventBusIsolate class

Atention The result of calling the event can be received later than the events called in the event handler on the isolate side

EventBusIsolate it consists of two Event bus, one on the side of the main isolate and the other in the working isolate. They exchange EventDTO and the results of the handlers' work among themselves.

Methods

addAllHandlerFromOtherBus(EventBus fromBus) → void
Adds all handlers from another EventBus to this one. Sets up stream cancellation to remove nodes when they're no longer needed.
inherited
dispose() → void
haveHandler<T>({String? path, String? target}) → bool
Checks if the bus contains a handler for the specified topic.
inherited
haveListener<T>({String? path, String? target}) → bool
Checks if the bus contains a listener for the specified topic.
inherited
lastData<T>({String? path, String? target}) → T?
Gets the last data sent to a specific topic. Returns null if no data has been sent to that topic.
inherited
listen<T>({String? path, String? target}) → Stream<T>
Listens to events on a specific topic. Creates a new EventNode if one doesn't exist for that topic. Returns a Stream of the data type T.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
removeAllHandlerPresentInOtherBus(EventBus otherBus) → void
Removes all handlers that are present in another EventBus from this one.
inherited
removeHandler<T>({String? path, String? target}) → void
Removes a handler from a specific topic. Disposes of the EventNode if it exists.
inherited
removeNode(Topic topic, EventNode node) → bool
This method is called every time a listener closes the stream. The node is removed if it has no listeners, no handler, and this is not a model bus.
inherited
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. If no handler exists, returns null.
override
setHandler<T>({T? initalData, String? path, String? target, required Handler<T> handler}) → void
Sets a handler for a specific topic. If an EventNode already exists for that topic, it updates the handler. Otherwise, it creates a new EventNode with the handler and initial data.
inherited
toString() → String
A string representation of this object.
inherited

Operators

operator ==(Object other) → bool
The equality operator.
