Namespace: Opc.UaFx
Assemblies: Opc.UaFx.Advanced.dll

Defines the abstract base class of all type nodes.

C# 

public abstract class OpcTypeNode : OpcNode, IOpcNode, IOpcNodeInfo


Inheritance Object › OpcNode › OpcTypeNode


Derived


Implements IOpcNode, IOpcNodeInfo

Events

Name Description
AfterApplyChanges Occurs after one or more changes on the node has been notified.
(Inherited from OpcNode)
BeforeApplyChanges Occurs before one or more changes on the node are notified.
(Inherited from OpcNode)

Properties

Name Description
Category Gets the NodeCategoryOpcAttribute which identifies the kind of node and is therefore used to classify the node regarding its use and purpose.
(Inherited from OpcNode)
Description Gets or sets the value of the optional DescriptionOpcAttribute which shall explain the meaning of the node.
(Inherited from OpcNode)
Descriptions Gets the OpcNodeGlobalization instance used to control the localization and other globalization related tasks for the Description attribute of the current node.
(Inherited from OpcNode)
DisplayName Gets or sets the value of the DisplayNameOpcAttribute which defines the localizable name of the node.
(Inherited from OpcNode)
DisplayNames Gets the OpcNodeGlobalization instance used to control the localization and other globalization related tasks for the DisplayName attribute of the current node.
(Inherited from OpcNode)
HasPendingChanges Gets a value indiciating whether there exists any pending change on the node.
(Inherited from OpcNode)
Id Gets the value of the NodeIdOpcAttribute which unambiguously identifies the node.
(Inherited from OpcNode)
IsAbstract Gets or sets a value indicating whether the OpcTypeNode is abstract and must be overridden.
Name Gets or sets the value of the BrowseNameOpcAttribute which defines the non-localizable human-readable name used when browsing the address space.
(Inherited from OpcNode)
Namespace (Inherited from OpcNode)
Parent Gets the parent node of the node.
(Inherited from OpcNode)
PendingChanges Gets a value indicating the most recent changes performed on the node since their last notification.
(Inherited from OpcNode)

ReadWriteAccessCallback (Inherited from OpcNode)
SuperTypeId Gets or sets the identifier of the OpcTypeNode which represents the super type of the type represented by this OpcTypeNode.
SymbolicName (Inherited from OpcNode)
Tag Gets or sets the object that contains additional user data about the node.
(Inherited from OpcNode)
UserWriteAccess Gets or sets the value of the optional UserWriteAccessOpcAttribute which exposes the possibilities of a client to write the attributes of the node taking user access rights into account.
(Inherited from OpcNode)
WriteAccess Gets or sets the value of the optional WriteAccessOpcAttribute which exposes the posibilities of a client to write the attributes of the node.
