Class NotificationHelper

java.lang.Object

org.mule.runtime.core.context.notification.NotificationHelper

public class NotificationHelper
extends Object

Simple class to fire notifications of a specified type over a ServerNotificationHandler. When the notification is to be sent on the context of the processing of a Event (meaning, the method used to fire the notification takes a Event argument), then this instance will delegate into a ServerNotificationHandler that corresponds to the MuleContext of that event. When the notification does not relate to a particular Event (for example, connection/reconnection/disconnection events), then a defaultNotificationHandler will be used

Constructor Detail

NotificationHelper

public NotificationHelper(ServerNotificationHandler defaultNotificationHandler,
                          Class<? extends ServerNotification> notificationClass,
                          boolean dynamicNotifications)

Creates a new NotificationHelper that emits instances of notificationClass class.

Parameters:

defaultNotificationHandler - The ServerNotificationHandler to be used on notifications which don't relate to a Event

notificationClass - The Class of the notifications to be fired by this helper

dynamicNotifications - If true, notifications will be fired directly to a ServerNotificationHandler responsible to decide to emit it or not. If false the notification will be checked to be enable or not at creation time

Method Detail

isNotificationEnabled

public boolean isNotificationEnabled()

Checks if the defaultNotificationHandler is enabled to fire instances of notificationClass. Use this method when planning to fire a notification that is not related to a Event (connect/disconnect/etc). Otherwise, use #isNotificationEnabled(Event) instead

Returns:

true if defaultNotificationHandler is enabled for notificationClass

isNotificationEnabled

public boolean isNotificationEnabled(MuleContext muleContext)

Checks if the ServerNotificationHandler associated to the given event is enabled to fire instances of notificationClass

Parameters:

muleContext - the Mule node.

Returns:

true if there is a ServerNotificationHandler enabled for notificationClass

fireNotification

public void fireNotification(Object source,
                             Event event,
                             FlowConstruct flowConstruct,
                             int action)

Fires a ConnectorMessageNotification for the given arguments using the ServerNotificationHandler associated to the given event and based on a ComponentLocation.

Parameters:

source -

event - a Event

flowConstruct - the FlowConstruct that generated the notification

action - the action code for the notification

fireNotification

public void fireNotification(ServerNotification notification)

Fires the given notification using the defaultNotificationHandler. Use this method when the notification is not related to any Event (for example, connect/disconnect/etc). Otherwise, use #fireNotification(ServerNotification, Event) instead

Parameters:

notification - a ServerNotification

fireNotification

public void fireNotification(ServerNotification notification,
                             MuleContext muleContext)

Fires the given notification using the ServerNotificationHandler that corresponds to the given event

Parameters:

notification - a ServerNotification

muleContext - the Mule node.
