CommonMappedNode Class

A utility base class objects mapped to OPC "Classic". Contains commonly used meta-members.

Object Model

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
<ComVisibleAttribute(False)>
<CLSCompliantAttribute(True)>
<TypeConverterAttribute(System.ComponentModel.ExpandableObjectConverter)>
Public Class CommonMappedNode 
   Inherits OpcLabs.BaseLib.LiveMapping.MappedObject

'Usage
 
Dim instance As CommonMappedNode

[ComVisible(false)]
[CLSCompliant(true)]
[TypeConverter(System.ComponentModel.ExpandableObjectConverter)]
public class CommonMappedNode : OpcLabs.BaseLib.LiveMapping.MappedObject

[ComVisible(false)]
[CLSCompliant(true)]
[TypeConverter(System.ComponentModel.ExpandableObjectConverter)]
public ref class CommonMappedNode : public OpcLabs.BaseLib.LiveMapping.MappedObject

Remarks

The DAMappedNode class is a pre-made base class for mapping OPC Data Access nodes. The UAMappedNode class is a pre-made base class for mapping OPC-UA data nodes.

You may (but do not have to) use this class as a base class for your objects that you map to OPC Data Access (or OPC-UA data) nodes. The class is already annotated with the DAType (or UAType) attribute, and contains properties that are mapped to useful meta-members, such as the NodeDescriptor property.

Sometimes it is not possible to use these mapped node classes, usually because you already have a class hierarchy where your objects are derived form a different base that you cannot change. In other cases, however, the DAMappedNode (or UAMappedNode) class serves as a handy shortcut that can make your code shorter.
