Properties

Default

static

Gets the default namespace used in cases there the concrete does not matter or is just unknown.

public static OpcNamespace Default { get; }

Public Shared ReadOnly Property [Default] As OpcNamespace

Property value

OpcNamespace

An instance of the OpcNamespace class its IsDefault property always returns the value true. While its Index property is equals to zero, its Uri and Value properties always return a null reference (Nothing in Visual Basic).

Index

Gets the index of the namespace within all namespaces of a server.

public int Index { get; }

Public ReadOnly Property Index As Integer

Property value

Int32

The index value which refers to the namespace in the namespace array of the server this OpcNamespace represents.

Remarks

The available namespaces of a server can be retrieved through reading the value of the namespaces-node using the node identifier 'OpcObjectTypes.Server.Namespaces'.

IsAbsolute

Gets a value indicating whether the namespace is absolute.

public bool IsAbsolute { get; }

Public ReadOnly Property IsAbsolute As Boolean

Property value

Boolean

The value true if an Uri or Value is given; otherwise the value false.

IsDefault

Gets a value indicating whether the namespace defines the default namespace without to refer to a specific address space.

public bool IsDefault { get; }

Public ReadOnly Property IsDefault As Boolean

Property value

Boolean

The value true if the namespace points to the generic address space; otherwise the value false if the namespace points to a foundation or user defined address space.

IsResolved

Gets a value indicating whether the namespace is resolved regarding its Index, Uri and Value.

public bool IsResolved { get; }

Public ReadOnly Property IsResolved As Boolean

Property value

Boolean

The value true if Index is not equals zero and Uri and Value are not a null reference (Nothing in Visual Basic).

Remarks

In case there this property provides the value true any call to Resolve will have no effect to the Index nor to the Uri and Value properties.

Scope

since v2.12

Gets scope within the current OpcNamespace has been declared and its metadata applies to.

public OpcNamespaceScope Scope { get; }

Public ReadOnly Property Scope As OpcNamespaceScope

Property value

OpcNamespaceScope

One of the members defined by the OpcNamespaceScope enumeration.

Uri

Gets the uniform resource identifier (URI) of the namespace represented and referred to by the Index.

public Uri Uri { get; }

Public ReadOnly Property Uri As Uri

Property value

Uri

The Uri to that the OpcNamespace refers using the Index.

Value

since v2.8

Gets the intrinsic value of the namespace represented and referred to by the Index.

public string Value { get; }

Public ReadOnly Property Value As String

Property value

String

The string to that the OpcNamespace refers using the Index.

Methods

Clear

static

Empties the known namespaces.

public static void Clear()

Public Shared Sub Clear()

Remarks

All namespaces retrieved until Clear is called are no longer referenced by the global / static namespace cache. Any so far retrieved namespaces are kept resolved / existing / valid and kept unchanged by subsequent global namespace operations, because they are not longer tracked nor updated by further global namespace retrieval nor resolve operations.
