HandleChildNodes Property (UAServerNode)



OpcLabs.ServerOpcUA Assembly > OpcLabs.EasyOpc.UA.NodeSpace Namespace > UAServerNode Class : HandleChildNodes Property
Determines whether the events from child nodes will be handled on this node as well.
Syntax
'Declaration
 
Public Overridable Property HandleChildNodes As Boolean
'Usage
 
Dim instance As UAServerNode
Dim value As Boolean
 
instance.HandleChildNodes = value
 
value = instance.HandleChildNodes
public virtual bool HandleChildNodes {get; set;}
public:
virtual property bool HandleChildNodes {
   bool get();
   void set (    bool value);
}

Property Value

true if the events from child nodes should be handled; otherwise, false.

The default value of this property is True.

Remarks

When set to true, events generated by child nodes will be handled by this node. This allows for centralized event handling at higher levels of the node hierarchy.

By setting this property to false, the request processing (using events) is effectively skipped on this node level only - but the request propagation to the eventual parent level is not affected.

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

Requirements

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