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.

ImplementNode(IOpcNode) When implemented in a derived class, implements the logic required to integrate the node into the underlying system.
ImportNodes When implemented in a derived class, offers the different OpcNodeSets which are imported prior any other nodes are created within the address space part organized by the current OpcNodeManager.
