Asynchronous call to create a Subscription
Subscriptions monitor a set of MonitoredItems for notifications and return them to the Client in response to Publish requests.
|

The default constructor.

inlinevirtual |
Checks if encodeable is the same object or has the same content
| encodeable |
Implements UnifiedAutomation.UaBase.IEncodeable.
|
getset |
The maximum number of notifications that the Client wishes to receive in a single Publish response.
A value of zero indicates that there is no limit.
The number of notifiations per Publish is the sum of monitoredItems in the DataChangeNotification and events in the EventNotificationList.
|
getset |
Indicates the relative priority of the Subscription.
When more than one Subscription needs to send Notifications, the Server should dequeue a Publish request to the Subscription with the highest priority number. For Subscriptions with equal priority the Server should dequeue Publish requests in a round-robin fashion. When the keep-alive period expires for a Subscription it shall take precedence regardless of its priority, in order to prevent the Subscription from expiring.
A Client that does not require special priority settings should set this value to zero.
|
getset |
A Boolean parameter with the following values:
The value of this parameter does not affect the value of the monitoring mode Attribute of MonitoredItems.
|
getset |
Requested lifetime count.
The lifetime count shall be a mimimum of three times the keep keep-alive count. When the publishing timer has expired this number of times without a Publish request being available to send a NotificationMessage, then the Subscription shall be deleted by the Server.
|
getset |
Requested maximum keep-alive count.
When the publishing timer has expired this number of times without requiring any NotificationMessage to be sent, the Subscription sends a keep-alive Message to the Client.
The negotiated value for this parameter is returned in the response.
If the requested value is 0, the server shall revise with the smallest supported keep-alive count.
|
getset |
This interval defines the cyclic rate that the Subscription is being requested to return Notifications to the Client.
This interval is expressed in milliseconds. This interval is represented by the publishing timer in the Subscription state table.
The negotiated value for this parameter returned in the response is used as the default sampling interval for MonitoredItems assigned to this Subscription.
If the requested value is 0 or negative, the server shall revise with the fastest supported publishing interval.
