메소드	설명
CreateAddressSpace ( IDictionary externalReferences ) : void	Does any initialization required before the address space can be used.
DeleteAddressSpace ( ) : void	Frees any resources allocated for the address space.
HistoricalAccessServerNodeManager ( IServerInternal server, ApplicationConfiguration configuration ) : System	Initializes the node manager.
New ( ISystemContext context, NodeState node ) : Opc.Ua.NodeId	Creates the NodeId for the specified node. This method is called by the NodeState.Create() method which initializes a Node from the type model. During initialization a number of child nodes are created and need to have NodeIds assigned to them. This implementation constructs NodeIds by constructing strings. Other implementations could assign unique integers or Guids and save the new Node in a dictionary for later lookup.
