SubscribeToChanges Operator

The SubscribeToChanges operator supports event subscriptions on any USM type using UCF filters. The parameters identify the MDR and the UCF filter values (entitytype, itemtype, recursive, id, and updatedAfter). In addition, the MaxNumberOfObjects parameter restricts the number of objects that the operator returns. The timeOut parameter specifies the number of seconds after which the subscription expires. The operator completes when either the number of objects are returned or the timeout expires.
