C# Class Opc.Ua.Server.CustomNodeManager2

A sample implementation of the INodeManager interface.

This node manager is a base class used in multiple samples. It implements the INodeManager interface and allows sub-classes to override only the methods that they need. This example is not part of the SDK because most real implementations of a INodeManager will need to modify the behavoir of the base class.

Inheritance: INodeManager2, INodeIdFactory, IDisposable

Public Methods

Method	Description
AddReferences ( IDictionary references ) : void	This method is used to add bi-directional references to nodes from other node managers. The additional references are optional, however, the NodeManager should support them.
Browse ( OperationContext context, ContinuationPoint &continuationPoint, IList references ) : void	Browses the references from a node managed by the node manager. The continuation point is created for every browse operation and contains the browse parameters. The node manager can store its state information in the Data and Index properties.
Call ( OperationContext context, IList methodsToCall, IList results, IList errors ) : void	Calls a method on the specified nodes.
ConditionRefresh ( OperationContext context, IList monitoredItems ) : ServiceResult	Tells the node manager to refresh any conditions associated with the specified monitored items. This method is called when the condition refresh method is called for a subscription. The node manager must create a refresh event for each condition monitored by the subscription.
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.
