PublisherEndpointDescriptor Property (UAPubSubResolverDescriptor)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.PubSub Namespace > UAPubSubResolverDescriptor Class : PublisherEndpointDescriptor Property
Endpoint descriptor of an OPC UA server that contains the publisher information.
Syntax
'Declaration
 
Public Property PublisherEndpointDescriptor As UAEndpointDescriptor
'Usage
 
Dim instance As UAPubSubResolverDescriptor
Dim value As UAEndpointDescriptor
 
instance.PublisherEndpointDescriptor = value
 
value = instance.PublisherEndpointDescriptor
public UAEndpointDescriptor PublisherEndpointDescriptor {get; set;}
public:
property UAEndpointDescriptor^ PublisherEndpointDescriptor {
   UAEndpointDescriptor^ get();
   void set (    UAEndpointDescriptor^ value);
}

Property Value

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

Remarks

This property is for accessing a configuration exposed in an information model of an OPC-UA server. In order to load a configuration from a file or similar concept, specify it using the PublisherFileResourceDescriptor property, and set ResolverKind to UAPubSubResolverKind.PublisherFile.

Because the OpcLabs.EasyOpc.UA.UAEndpointDescriptor has an implicit conversion 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 (representing the endpoint URL, or a so-called OPC UA endpoint descriptor string), or a System.Uri object, when setting this property, and the corresponding endpoint descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.UAEndpointDescriptor.FromString or OpcLabs.EasyOpc.UA.UAEndpointDescriptor.FromUri static method instead.

Also, because the OpcLabs.EasyOpc.UA.Discovery.UAApplicationElement and OpcLabs.EasyOpc.UA.Discovery.UADiscoveryElement have an implicit conversion to OpcLabs.EasyOpc.UA.UAEndpointDescriptor, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a OpcLabs.EasyOpc.UA.Discovery.UAApplicationElement or OpcLabs.EasyOpc.UA.Discovery.UADiscoveryElement (results from OPC UA discovery) in place of OpcLabs.EasyOpc.UA.UAEndpointDescriptor when setting this property, and the corresponding endpoint descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can convert a (non-null) OpcLabs.EasyOpc.UA.Discovery.UAApplicationElement or OpcLabs.EasyOpc.UA.Discovery.UADiscoveryElement to OpcLabs.EasyOpc.UA.UAEndpointDescriptor using the OpcLabs.EasyOpc.UA.Discovery.UAApplicationElement.ToUAEndpointDescriptor or OpcLabs.EasyOpc.UA.Discovery.UADiscoveryElement.ToUAEndpointDescriptor method instead.
