C# Class Quickstarts.QuickstartNodeManager

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: INodeManager, INodeIdFactory, IDisposable

Méthodes publiques

Méthode	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.
