OpcNodeManager Class

Namespace: Opc.UaFx.Server
Assemblies: Opc.UaFx.Advanced.dll

Provides an abstract base class used to organize and maintain the address space or only a part of it. This includes the definition of the nodes in the address space as well as the processing of different node operations to interact with the underlying system.

C#
