IReactNotificationService

Kind: interface

The notification service that can be used to send notifications between different components in an app. Use the Subscribe method to subscribe to notifications and the SendNotification method to send notifications.

Methods

SendNotification

void SendNotification(IReactPropertyName notificationName, Object sender, Object data)

Sends the notification with notificationName.

• notificationName is the name of the notification to send. It must not be null.
• sender is the object that sends notification. It can be null.
• data is the data associated with the notification. It can be null. Consider using IReactPropertyBag for sending semi-structured data. It can be created using the ReactPropertyBagHelper.CreatePropertyBag method.

Subscribe

IReactNotificationSubscription Subscribe(IReactPropertyName notificationName, IReactDispatcher dispatcher, ReactNotificationHandler handler)

Subscribes to a notification.

• notificationName is a non-null notification name that can belong to a specific namespace like any IReactPropertyName.
• dispatcher is used to call notification handlers. If it is null, then the handler is called synchronously.
• handler is a delegate that can be implemented as a lambda to handle notifications. The method returns a IReactNotificationSubscription that must be kept alive while the subscription is active. The subscription is removed when the IReactNotificationSubscription is destroyed.
