Type

OpcAnonymousAcl

Namespace

Opc.UaFx.Server

Assembly

Opc.UaFx.Advanced.dll

Package

Opc.UaFx.Advanced v2.59.0

Inherits members from OpcAccessControlList.

Constructors

OpcAnonymousAcl

since v2.6

Initializes a new instance of the OpcAnonymousAcl class using the owner specified.

public OpcAnonymousAcl(OpcServerBase owner)

Public Sub New(owner As OpcServerBase)

Parameters

Name	Type	Description
owner	OpcServerBase	The OpcServerBase the list belongs to.

Exceptions

Exception	Condition
ArgumentNullException	The owner is a null reference (Nothing in Visual Basic).

Remarks

The entries created by the list evaluate operations and endpoints using the mode Whitelist.

Properties

IsConfigured

override

Gets a value indicating whether anonymous access is configured.

public override bool IsConfigured { get; }

Public Overrides ReadOnly Property IsConfigured As Boolean

Property value

Boolean

The value true if the user token policies of the Configuration contain an anonymous policy, or if they contain no policy at all and no other access control list is enabled; otherwise the value false.

Overrides

IsConfigured

Remarks

Since the value depends on the other access control lists, enabling one of them disables anonymous access, as long as IsEnabled of this list has not been set explicitly. While the server runs, the value follows the configuration it has been started with, see IsConfigured.
