Public Methods
 NameDescription
Public Method (Inherited from object)
Public MethodServes as the default hash function. (Inherited from object)
Public MethodGets the System.Type of the current instance. (Inherited from object)
Public Methodstatic (Shared in Visual Basic)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.
