Subscription and Un-Subscription
When a subscription is done from a JSON-based application, a notification is sent to the ip port where the
application is running when there is change for which the user has subscribed.
Actual notification is sent asynchronously as an HTTP Post, with the following structure:
{result:
{method:
"notification",notificationType: "ScreenDestChanged",change: { add: [2],
remove: [], update: [0, 1, 2] }}}.
The change field contains the XmlId(s) of the screens that were added/removed or updated.
All subscriptions are lost once the Event Master processor is restarted, and they must be
subscribed again if required.
