) 

Parameters

client

The client object that will perform the operation.

endpointDescriptor

Endpoint descriptor. Identifies the OPC-UA server.

nodeDescriptor

Node descriptor. Identifies the node in OPC server's address space.

browseParameters

Browse parameters such as node classes and reference types to be returned.

Return Value

Performs a breadth-first traversal.

The root position in a tree will correspond to the specified starting node. The OpcLabs.EasyOpc.UA.Graphs.UATreePosition object for the root is special one, in that from its OpcLabs.EasyOpc.UA.AddressSpace.UANodeElement properties, only its NodeId is filled in.

You can obtain nodeDescriptor e.g. by calling one of the browsing methods on OpcLabs.EasyOpc.UA.EasyUAClient object.

Target Platforms: .NET Framework: Windows 7 with SP1, Windows Server 2012; .NET Core: Linux, Microsoft Windows
