Class NotificationCenter

java.lang.Object

com.optimizely.ab.notification.NotificationCenter

public class NotificationCenter
extends java.lang.Object

NotificationCenter handles all notification listeners. It replaces NotificationBroadcaster and is intended to be more flexible. NotificationCenter is a holder for a set of supported NotificationManager instances. If a notification object is sent via send(Object) that is not supported an OptimizelyRuntimeException will be thrown. This is an internal interface so usage should be restricted to the SDK. Supported notification classes are setup within NotificationCenter() as an unmodifiable map so additional notifications must be added there. Currently supported notification classes are: * ActivateNotification * TrackNotification * DecisionNotification with this class replacing ActivateNotification
