Parameters

state

The state object (can be any value supplied by your code); available in event notifications.

The value of this parameter can be null (Nothing in Visual Basic).

resolverDescriptor

Describes how the PubSub logical information should be resolved to physical.

The value of this parameter cannot be null (Nothing in Visual Basic).

connectionDescriptor

Descriptor for a PubSub connection (using physical parameters, or logical name).

Because the OpcLabs.EasyOpc.UA.PubSub.UAPubSubConnectionDescriptor has an implicit conversion from OpcLabs.BaseLib.Networking.ResourceAddress and System.String, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a OpcLabs.BaseLib.Networking.ResourceAddress object, or a string (the so-called resource description string, usually a resource URL) in place of this parameter, and the corresponding OPC UA PubSub connection descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromResourceAddress or FromString static method instead.

Also, because the OpcLabs.EasyOpc.UA.PubSub.Configuration.UAPubSubConnectionElement has an implicit conversion to OpcLabs.EasyOpc.UA.PubSub.UAPubSubConnectionDescriptor, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a OpcLabs.EasyOpc.UA.PubSub.Configuration.UAPubSubConnectionElement (from PubSub configuration) in place of this parameter, and the corresponding OPC UA PubSub connection descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can convert a OpcLabs.EasyOpc.UA.PubSub.Configuration.UAPubSubConnectionElement to OpcLabs.EasyOpc.UA.PubSub.UAPubSubConnectionDescriptor using the ToUAPubSubConnectionDescriptor static method instead.

The value of this parameter cannot be null (Nothing in Visual Basic).
