Parameters

client

The client object that will perform the operation.

serverDescriptor

Server descriptor. Identifies the OPC-DA server.

Return Value

If you want to enumerate through a sequence of the tree nodes, convert the result to a sequence using the OpcLabs.BaseLib.Graphs.Extensions.ITreeTraversableExtension.ToEnumerable<T> method.

The method automatically prevents recursion into nodes that have already been traversed.

The root position in a tree will correspond to the ObjectsFolder node. The OpcLabs.EasyOpc.DataAccess.Graphs.DANodeTreePosition object for the root is special one, in that from its OpcLabs.EasyOpc.DataAccess.AddressSpace.DANodeElement properties, only its ItemId is filled in.
