OpcAddNode(OpcNodeCategory, OpcName)

protected

Initializes a new instance of the OpcAddNode class using the specified category of node to add, which shall be accessible by the name defined. The according OpcNodeId to identify and access the new node is determined by the service.

protected OpcAddNode(OpcNodeCategory category, OpcName name)

Protected Sub New(category As OpcNodeCategory, name As OpcName)

Parameters

Name	Type	Description
category	OpcNodeCategory	The OpcNodeCategory which classifies the new node to add regarding one of the classifications defined by the OpcNodeCategory enumeration.
name	OpcName	The OpcName through that the new node can be accessed.

Exceptions

Exception	Condition
ArgumentException	The name is equals Null.
ArgumentNullException	The name is a null reference (Nothing in Visual Basic).

OpcAddNode(OpcNodeCategory, OpcName, OpcNodeId)

protected

Initializes a new instance of the OpcAddNode class using the specified category of node to add, which shall be accessible by the name and nodeId defined. The new node will be a child of the ObjectsFolder node.

protected OpcAddNode(OpcNodeCategory category, OpcName name, OpcNodeId nodeId)

Protected Sub New(
    category As OpcNodeCategory,
    name As OpcName,
    nodeId As OpcNodeId)

Parameters

Name	Type	Description
category	OpcNodeCategory	The OpcNodeCategory which classifies the new node to add regarding one of the classifications defined by the OpcNodeCategory enumeration.
name	OpcName	The OpcName through that the new node can be accessed.
nodeId	OpcNodeId	The OpcNodeId through that the new node can be identified and accessed. In case there Null is specified the server will determine the according OpcNodeId by its own.

Exceptions

Exception	Condition
ArgumentException	The name is equals Null.
ArgumentNullException	The name or nodeId is a null reference (Nothing in Visual Basic).

OpcAddNode(OpcNodeCategory, OpcName, OpcNodeId, OpcNodeId)

protected

Initializes a new instance of the OpcAddNode class using the specified category of node to add, which shall be accessible by the name and nodeId defined. The new node will be a child of the node identified by parentNodeId.

protected OpcAddNode(
    OpcNodeCategory category,
    OpcName name,
    OpcNodeId nodeId,
    OpcNodeId parentNodeId)

Protected Sub New(
    category As OpcNodeCategory,
    name As OpcName,
    nodeId As OpcNodeId,
    parentNodeId As OpcNodeId)

Parameters

Name	Type	Description
category	OpcNodeCategory	The OpcNodeCategory which classifies the new node to add regarding one of the classifications defined by the OpcNodeCategory enumeration.
name	OpcName	The OpcName through that the new node can be accessed.
nodeId	OpcNodeId	The OpcNodeId through that the new node can be identified and accessed. In case there Null is specified the server will determine the according OpcNodeId by its own.
parentNodeId	OpcNodeId	The OpcNodeId of the parent node.

Exceptions

Exception	Condition
ArgumentException	The parentNodeId is equals Null or name is equals Null.
ArgumentNullException	The name, nodeId or parentNodeId is a null reference (Nothing in Visual Basic).

Properties

Category

Gets a value indicating the classification of the node in the address space.

public OpcNodeCategory Category { get; }

Public ReadOnly Property Category As OpcNodeCategory

Property value

OpcNodeCategory

One of the members defined by the OpcNodeCategory enumeration which classifies the node within the address space.

Description

Gets or sets the localized description of the meaning of the node.

public OpcText Description { get; set; }

Public Property Description As OpcText

Property value

OpcText

An instance of the OpcText class which provides the localized description of the node or a null reference (Nothing in Visual Basic). In case of a null reference (Nothing in Visual Basic) the server defined default value of the attribute is used.

DisplayName

Gets or sets the localized name of the node.

public OpcText DisplayName { get; set; }

Public Property DisplayName As OpcText

Property value

OpcText

An instance of the OpcText class which provides the localized name of the node or a null reference (Nothing in Visual Basic). In case of a null reference (Nothing in Visual Basic) the server defined default value of the attribute is used.

Name

Gets the non-localised human-readable name of the node in the address space.

public OpcName Name { get; }

Public ReadOnly Property Name As OpcName

Property value

OpcName

An instance of the OpcName class used to identify a node when browsing the address space.

ParentNodeId

Gets the identifier of the existing parent node of the new node.

public OpcNodeId ParentNodeId { get; }

Public ReadOnly Property ParentNodeId As OpcNodeId

Property value

OpcNodeId

An instance of the OpcNodeId which identifies an existing node to use as the parent node of the new node.

SupportsNullNodeId

protected · override

Gets a value indicating whether the OpcAddNode supports instances of the OpcNodeId class its IsNull provides a value equals to the value true.

protected override bool SupportsNullNodeId { get; }

Protected Overrides ReadOnly Property SupportsNullNodeId As Boolean

Property value

Boolean

The value true in the case there the OpcNodeId instance of the command can be a null-node-id; otherwise the value false.

Overrides

SupportsNullNodeId

Remarks

In case there this property provides the value false and an instance of the OpcNodeId is passed to the constructor of this class an ArgumentException will be thrown.

UserWriteAccess
