Of

static

Creates the model a node type defines for its instances.

public static OpcNodeModel Of(IOpcNodeTypeInfo nodeType)

Public Shared Function [Of](nodeType As IOpcNodeTypeInfo) As OpcNodeModel

Parameters

Name	Type	Description
nodeType	IOpcNodeTypeInfo	The IOpcNodeTypeInfo whose model is to be created.

Returns

OpcNodeModel

A new instance of the OpcNodeModel class with the children of the nodeType and their attributes.

Exceptions

Exception	Condition
ArgumentNullException	The nodeType is a null reference (Nothing in Visual Basic).

Remarks

A node created without a model keeps the defaults of the SDK, such as a variable that clients can read and write. A node created with the model of its type takes the attributes the type defines instead, such as the access levels a companion specification declares in its NodeSet. The node manager can pass it once the NodeSet is imported, for example in CreateNodes:

var type = this.SystemContext.GetNodeType(OpcMachineryNodes.MachineIdentificationType);
var identification = new OpcMachineIdentificationNode(OpcNodeModel.Of(type), machine, name);
