Public Methods

Method	Description
Clone ( NodeSource parent ) : NodeSource	Makes a copy of the node without any node ids specified.
Create ( NodeId parentId, NodeId referenceTypeId, NodeId nodeId, QualifiedName browseName, uint numericId, object configuration ) : void	Updates the object based from a configuration.
CreateCopy ( NodeId nodeId ) : ILocalNode
Delete ( ) : void	Deletes the Node from the address space. This method is called deletes all nodes created when the type was instantiated. The subclass must implement DeleteChildren() to remove nodes that are not part of the type model. Before any processing starts this method calls OnBeforeDelete(). After successfully deleting all nodes this method calls OnAfterDelete().
Dispose ( ) : void	Frees any unmanaged resources.
GetDisplayPath ( int count ) : LocalizedText	Builds a path of display names starting with the top most parent.
Initialize ( NodeSource source ) : void	Initializes a node from another node.
MemberwiseClone ( ) : object	Makes a copy of the node without any node ids specified.
OverrideValueStatus ( StatusCode statusCode ) : void	Recursively overrides the status for value of any child variables.
Read ( IOperationContext context, uint attributeId, DataValue value ) : ServiceResult
Subscribe ( IMonitoredItem monitoredItem ) : void	Adds a subscription to the source.
SupportsAttribute ( uint attributeId ) : bool
ToString ( ) : string	Returns a string representation of the HierarchyReference.
ToString ( string format, IFormatProvider formatProvider ) : string	Returns a string representation of the HierarchyReference.
Unsubscribe ( IMonitoredItem monitoredItem ) : void	Removes a subscription from the source.
Write ( uint attributeId, DataValue value ) : ServiceResult
