Class NotificationMethodMapBuilder

java.lang.Object

org.ovirt.engine.core.notifier.methods.NotificationMethodMapBuilder

public class NotificationMethodMapBuilder
extends Object

The group of classes used to map a factory for each notification method.
Different notification methods might require different instantiation methods of the notification
method implementation class.

Components description:
EventSender - interface of any notification method implementation
EventSenderMailImpl - implements email notification method
NotificationMethodFactory - interface of factories of notification method classes. Each factory will define the
the policy of creation notification classes (some factories might produce a single class for all notifications, others
might produce a single instance per notification)
NotificationMethodFactoryEmailImpl - factory for producing a single email notification method class
NotificationMethodMapBuilder.NotificationMethodFactoryMapper - stores the association between the notification method type to its factory
NotificationMethodMapBuilder - creates the map of notification method type to the factory. Could be recreated upon
modification of the notification method types.

Adding new notification method
The following steps will describe how to add and register new notification method. Let's add support for SMS notification method:

Add new notification method to EventNotificationMethods, e.g. SMS(1) Add an entry representing the SMS notification method to database table event_notification_methods Create EventSenderSMSImpel which implements the EventSender. The class will be responsible for dispatching a notification via SMS
Create NotificationMethodFactorySMS which implements the NotificationMethodFactory. The class will be responsible for instantiating the SMS sender class. Register the notification method and the factory in NotificationMethodMapBuilder#createMethodsMapper(List)
