OpcNodeId Members

The value true if the Namespace is an absolute namespace and is therefore not server dependent upon its Index; otherwise the value false.

IsNull

Gets a value indicating whether the node identifier is a null identifier.

csharp

public bool IsNull { get; }

vbnet

Public ReadOnly Property IsNull As Boolean

Property value

The value true if the Value defines a Type specific definition of a null identifier; otherwise the value false.

Remarks

A null identifier originates when a node identifier is created using:

A byte-array as the identifier value. In case there the Opaque identifier value is a null reference (Nothing in Visual Basic) or an empty array (the length is equals zero).
A Guid as the identifier value. In case there the Guid identifier value is equals to Empty.
A int or uint as the identifier value. In case there the Numeric identifier value is equals to zero.
A string as the identifier value. In case there the String identifier value is a null reference (Nothing in Visual Basic) or equals to Empty.

Namespace

Gets the OpcNamespace used by the OpcNodeId to describe the namespace to that the node identifier belongs.

csharp

public OpcNamespace Namespace { get; }

The Uri to that the OpcNodeId refers using the NamespaceIndex.

Null

static

Gets the default null node identifier.

csharp

public static OpcNodeId Null { get; }

vbnet

Public Shared ReadOnly Property Null As OpcNodeId

Property value

An instance of the OpcNodeId which can be used for general purpose in cases there a null node identifier is enough.

OriginalFormat

Gets the original format of the node identifier from that the instance was constructed.

csharp

public OpcNodeIdFormat OriginalFormat { get; }

vbnet

Public ReadOnly Property OriginalFormat As OpcNodeIdFormat

Property value

vbnet

Public ReadOnly Property OriginalString As String

Property value

A string containing the exact node identifier specified from this instance was constructed; otherwise Empty.

Path

Gets the path portion of the Value which refers to the logical (= physically not available in the address space) portion of the identifier.

vbnet

Public ReadOnly Property Path As OpcNamePath

Property value

OpcNamePath

An instance of the OpcNamePath identifying the browse path to use to determine the according entity through the physically existing members in the address space.

Remarks

A OpcNodeId with a OpcNamePath not equals Empty identifies an entity which is not necessarily physically available in the address space. We define that the identifier of the physical ancestor of the entity identified by such an identifier (its logical owner which is physically available in the address space) is encoded in the Value of its OpcNodeId followed by the string formatted Path. Excluding the Path from this OpcNodeId (see ExcludePath) results into the identifier of the 'physical' ancestor. Using these (path-less) identifier the ancestor can be looked up in the address space and can be used to browse for the entity using the Path of the identifier of its successor.
