Add(UANodeId,UAPermissions) Method



OpcLabs.EasyOpcUAPrimitives Assembly > OpcLabs.EasyOpc.UA.Security.Subject Namespace > UAPermissionAssignment Class > Add Method : Add(UANodeId,UAPermissions) Method
The node ID of the role.

Because the OpcLabs.EasyOpc.UA.AddressSpace.UANodeId has an implicit conversion from System.String, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a string (representing the expanded text of the nodeId) in place of this parameter, and the corresponding OPC UA node Id will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.AddressSpace.UANodeId.UANodeId Constructor(String) constructor instead.

The value of this parameter cannot be null (Nothing in Visual Basic).

The permissions to assign to the role.
Adds a role with the specified permissions to the permission assignment.
