Properties

Attribute

Gets the attribute the operand refers to.

public OpcAttribute Attribute { get; }

Public ReadOnly Property Attribute As OpcAttribute

Property value

OpcAttribute

The attribute of the node; Value if no attribute has been specified.

NodeId

Gets the identifier of the type definition the operand starts from.

public OpcNodeId NodeId { get; }

Public ReadOnly Property NodeId As OpcNodeId

Property value

OpcNodeId

The identifier of the type definition.

Remarks

Despite its name, the property provides the type definition of the operand, not the identifier of a node instance.

NodePath

Gets the path of browse names from the type definition to the node whose attribute the operand refers to.

public OpcNamePath NodePath { get; }

Public ReadOnly Property NodePath As OpcNamePath

Property value

OpcNamePath

The path or a null reference (Nothing in Visual Basic) if the operand has been created without a path.
