Extension Methods
| Name | Description |
| ChangeDataSetFieldSubscription | Overloaded. Changes parameters of an existing dataset field subscription. |
| ChangeDataSetSubscription | Changes parameters of an existing dataset subscription, specifying a new filter. |
| GetSubscribeDataSetFieldArguments | Obtains parameters of a specified dataset subscription. |
| PullDataSetMessage | Attempts to pull a dataset message event notification subscribed to by the SubscribeDataSet method. |
| PullResolverAccess | Attempts to pull a resolver access notification. |
| PullSubscriptionResolved | Attempts to pull a subscription resolved notification. |
| SubscribeDataSet | Overloaded. Subscribes to a dataset, using a PubSub connection descriptor, and no filter. |
| SubscribeDataSetField | Overloaded. Subscribes to a single dataset field from a dataset, using arguments object. |
| TestConnection | Overloaded. Tests whether an OPC UA PubSub connection can be successfully established. Synchronous.
The method returns normally when the test passes. The method throws a OpcLabs.EasyOpc.UA.OperationModel.UAException when there is an error establishing the connection.
Due to asynchronous nature of some communication channels, successful test outcome does not always imply that a connection has been fully established.
The waitMilliseconds parameter is not a timeout in its traditional sense, i.e. a maximum time allowed for the operation. Here, this method actually waits for the time given by waitMilliseconds parameter unless a failure occurs. |
| TestConnectionAsync | Overloaded. Tests whether an OPC UA PubSub connection can be successfully established. Asynchronous.

| UnsubscribeDataSetField | Unsubscribes from a dataset field specified by its integer handle. |
