OpcBrowseNodeContext Class

Namespace: Opc.UaFx.Client
Assemblies: Opc.UaFx.Advanced.dll

Describes a single node accessed by an OpcClient for browsing.

C# 

public class OpcBrowseNodeContext : OpcNodeAccessContext


Inheritance Object › OpcNodeAccessContext › OpcBrowseNodeContext

Remarks

The OpcBrowseNodeContext is used whenever node browsing is performed using a specific OpcClient. An instance of this class does then provide the OpcNodeId of the node to browse on, the OpcClient, the OpcViewDescription of the view being browsed and a list of OpcNodeId objects identifying the different reference types to include for the browse operation.

Using this class or a scenario specific derivate of this class does simplify the API used for a specific node browse operation by reducing the amount of arguments (bound by the context object) they have to be passed.
