OpcLabs.EasyOpcClassicCore Assembly > OpcLabs.EasyOpc.AlarmsAndEvents Namespace > AENodeDescriptor Class : BrowsePathStartingNodeDescriptor Property
The starting node descriptor of the browse path.
Syntax
'Declaration
 
Public Shadows Property BrowsePathStartingNodeDescriptor As AENodeDescriptor
'Usage
 
Dim instance As AENodeDescriptor
Dim value As AENodeDescriptor
 
instance.BrowsePathStartingNodeDescriptor = value
 
value = instance.BrowsePathStartingNodeDescriptor
public new AENodeDescriptor BrowsePathStartingNodeDescriptor {get; set;}
public:
new property AENodeDescriptor^ BrowsePathStartingNodeDescriptor {
   AENodeDescriptor^ get();
   void set (    AENodeDescriptor^ value);
}

Property Value

This value of this property can be null (Nothing in Visual Basic).

The default value of this property is null.

Remarks

When the starting node descriptor is null, the browse path starts at the root node.

This value is ignored if BrowsePath is null.

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.

Because the AENodeDescriptor has an implicit conversion from System.String and OpcLabs.EasyOpc.AlarmsAndEvents.AddressSpace.AENodeElement, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a string (representing the qualified name of the node), or a OpcLabs.EasyOpc.AlarmsAndEvents.AddressSpace.AENodeElement object (result from OPC browsing), in place of AENodeDescriptor value when setting this property, and the corresponding OPC A&E node descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromString or FromAENodeElement static method instead.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
