UAPubSubConnectionDescriptor Constructor(ResourceAddress,String)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.PubSub Namespace > UAPubSubConnectionDescriptor Class > UAPubSubConnectionDescriptor Constructor : UAPubSubConnectionDescriptor Constructor(ResourceAddress,String)
Network address information in the form of a resource descriptor (can be represented as URL string).

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

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

The URI string of the PubSub transport profile.

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

Initializes a new instance of the class, specifying the resource address, and transport profile URI string.
