CreateAddressSpace ( IDictionary externalReferences ) : void	Does any initialization required before the address space can be used. The externalReferences is an out parameter that allows the node manager to link to nodes in other node managers. For example, the 'Objects' node is managed by the CoreNodeManager and should have a reference to the root folder node(s) exposed by this node manager.
DataAccessServerNodeManager ( IServerInternal server, ApplicationConfiguration configuration ) : System	Initializes the node manager.
DeleteAddressSpace ( ) : void	Frees any resources allocated for the address space.
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.

CreateAddressSpace() 공개 메소드

Does any initialization required before the address space can be used.

The externalReferences is an out parameter that allows the node manager to link to nodes in other node managers. For example, the 'Objects' node is managed by the CoreNodeManager and should have a reference to the root folder node(s) exposed by this node manager.

public CreateAddressSpace ( IDictionary externalReferences ) : void
externalReferences	IDictionary
리턴	void

DataAccessServerNodeManager() 공개 메소드

Initializes the node manager.

public DataAccessServerNodeManager ( IServerInternal server, ApplicationConfiguration configuration ) : System

New() 공개 메소드

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.

public New ( ISystemContext context, NodeState node ) : Opc.Ua.NodeId
context	ISystemContext	The context.
node	NodeState	The node.
리턴	Opc.Ua.NodeId
