UAPubSubResolverDescriptor Constructor(ResourceDescriptor)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.PubSub Namespace > UAPubSubResolverDescriptor Class > UAPubSubResolverDescriptor Constructor : UAPubSubResolverDescriptor Constructor(ResourceDescriptor)
Resource descriptor specifying the location of the PubSub configuration file.

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

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

Creates a descriptor for resolving with use of the specified file resource.
