class ObservableObjectmethod

emit()

Emits an event, immediately calling all event handlers.

emit(event?: ObservableEvent): this;

emit(event: string, data?: Record<string, any>): this;

Notes

• Events can be handled using ObservableObject.listen() or ObservableObject.attach().
• If the first argument is undefined, no event is emitted at all and this method returns quietly.

Parameters

• event — An instance of ObservableEvent, or an event name; if a name is provided, an instance of ObservableEvent will be created by this method
• data — Additional data to be set on ObservableEvent.data, if event is a string; the object is treated as immutable and may be reused between events.
