Equality Operator (UAPubSubConnectionDescriptor)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.PubSub Namespace > UAPubSubConnectionDescriptor Class : Equality Operator
First object to be compared.

Because the 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 UAWriterGroupDescriptor.FromString static method instead.

Also, because the OpcLabs.EasyOpc.UA.PubSub.Configuration.UAPubSubConnectionElement has an implicit conversion to 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 UAPubSubConnectionDescriptor using the OpcLabs.EasyOpc.UA.PubSub.Configuration.UAPubSubConnectionElement.ToUAPubSubConnectionDescriptor static method instead.

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