Provides a specialisation of the [OpcNodeManager](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.server.opcnodemanager/) to import nodes from one or more [OpcNodeSet](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcnodeset/)s and implement them using a [OpcImplementNodeCallback](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.server.opcimplementnodecallback/).

| [ImplementNode](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.server.opcnodesetmanager/members#implementnode)<span class="api-meta">protected · override</span> | When implemented in a derived class, implements the logic required to integrate the `node` into the underlying system. |
| [ImportNodes](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.server.opcnodesetmanager/members#importnodes)<span class="api-meta">protected · override</span> | When implemented in a derived class, offers the different [OpcNodeSet](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcnodeset/)s which are imported prior any other nodes are created within the address space part organized by the current [OpcNodeManager](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.server.opcnodemanager/). |

Inherits members from [OpcNodeManager](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.server.opcnodemanager/members).
