C# Class FileSystem.FileSystemNodeManager

A node manager for a variety of test data.

Inheritance: Opc.Ua.Sample.SampleNodeManager

Exibir arquivo Open project: OPCFoundation/UA-.NET

Public Methods

Method	Description
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.
FileSystemNodeManager ( Opc server, string systemRoot ) : System	Initializes the node manager.

Protected Methods

Method	Description
Dispose ( bool disposing ) : void	An overrideable version of the Dispose.
GetManagerHandle ( ISystemContext context, Opc.Ua.NodeId nodeId, NodeState>.IDictionary cache ) : object	Returns a unique handle for the node. This must efficiently determine whether the node belongs to the node manager. If it does belong to NodeManager it should return a handle that does not require the NodeId to be validated again when the handle is passed into other methods such as 'Read' or 'Write'.
LoadPredefinedNodes ( ISystemContext context ) : NodeStateCollection	Loads a node set from a file or resource and addes them to the set of predefined nodes.
OnCreateMonitoredItem ( ISystemContext systemContext, MonitoredItemCreateRequest itemToCreate, MonitoredNode monitoredNode, DataChangeMonitoredItem monitoredItem ) : void	Does any processing after a monitored item is created.
OnDeleteMonitoredItem ( ISystemContext systemContext, MonitoredNode monitoredNode, DataChangeMonitoredItem monitoredItem ) : void	Does any processing after a monitored item is deleted.
OnModifyMonitoredItem ( ISystemContext systemContext, MonitoredItemModifyRequest itemToModify, MonitoredNode monitoredNode, DataChangeMonitoredItem monitoredItem, double previousSamplingInterval ) : void	Does any processing after a monitored item is created.
OnSetMonitoringMode ( ISystemContext systemContext, MonitoredNode monitoredNode, DataChangeMonitoredItem monitoredItem, MonitoringMode previousMode, MonitoringMode currentMode ) : void	Does any processing after a monitored item is created.

Private Methods

Method	Description
AddNodeHierarchyToCache ( ISystemContext context, NodeState root ) : void	Adds the hierachy of nodes to the cache.
RemoveNodeHierarchyFromCache ( ISystemContext context, NodeState root ) : void	Removes the hierachy of nodes from the cache.
StartMonitoring ( ISystemContext context, MonitoredNode monitoredNode ) : void	Returns true if the system must be scanning to provide updates for the monitored item.
StopMonitoring ( ISystemContext context, MonitoredNode monitoredNode ) : void	Returns true if the system must be scanning to provide updates for the monitored item.

Method Details

CreateAddressSpace() public method

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
return	void

Dispose() protected method

An overrideable version of the Dispose.

protected Dispose ( bool disposing ) : void
disposing	bool
return	void

FileSystemNodeManager() public method

Initializes the node manager.

public FileSystemNodeManager ( Opc server, string systemRoot ) : System
server	Opc
systemRoot	string
return	System

GetManagerHandle() protected method

Returns a unique handle for the node.

This must efficiently determine whether the node belongs to the node manager. If it does belong to NodeManager it should return a handle that does not require the NodeId to be validated again when the handle is passed into other methods such as 'Read' or 'Write'.

protected GetManagerHandle ( ISystemContext context, Opc.Ua.NodeId nodeId, NodeState>.IDictionary cache ) : object
context	ISystemContext
nodeId	Opc.Ua.NodeId
cache	NodeState>.IDictionary
return	object

LoadPredefinedNodes() protected method

Loads a node set from a file or resource and addes them to the set of predefined nodes.

protected LoadPredefinedNodes ( ISystemContext context ) : NodeStateCollection
context	ISystemContext
return	NodeStateCollection

OnCreateMonitoredItem() protected method

Does any processing after a monitored item is created.

protected OnCreateMonitoredItem ( ISystemContext systemContext, MonitoredItemCreateRequest itemToCreate, MonitoredNode monitoredNode, DataChangeMonitoredItem monitoredItem ) : void
systemContext	ISystemContext
itemToCreate	Opc.Ua.MonitoredItemCreateRequest
monitoredNode	Opc.Ua.Sample.MonitoredNode
monitoredItem	Opc.Ua.Sample.DataChangeMonitoredItem
return	void

OnDeleteMonitoredItem() protected method

Does any processing after a monitored item is deleted.

protected OnDeleteMonitoredItem ( ISystemContext systemContext, MonitoredNode monitoredNode, DataChangeMonitoredItem monitoredItem ) : void
systemContext	ISystemContext
monitoredNode	Opc.Ua.Sample.MonitoredNode
monitoredItem	Opc.Ua.Sample.DataChangeMonitoredItem
return	void

OnModifyMonitoredItem() protected method

Does any processing after a monitored item is created.

protected OnModifyMonitoredItem ( ISystemContext systemContext, MonitoredItemModifyRequest itemToModify, MonitoredNode monitoredNode, DataChangeMonitoredItem monitoredItem, double previousSamplingInterval ) : void
systemContext	ISystemContext
itemToModify	Opc.Ua.MonitoredItemModifyRequest
monitoredNode	Opc.Ua.Sample.MonitoredNode
monitoredItem	Opc.Ua.Sample.DataChangeMonitoredItem
previousSamplingInterval	double
return	void

OnSetMonitoringMode() protected method

Does any processing after a monitored item is created.

protected OnSetMonitoringMode ( ISystemContext systemContext, MonitoredNode monitoredNode, DataChangeMonitoredItem monitoredItem, MonitoringMode previousMode, MonitoringMode currentMode ) : void
systemContext	ISystemContext
monitoredNode	Opc.Ua.Sample.MonitoredNode
monitoredItem	Opc.Ua.Sample.DataChangeMonitoredItem
previousMode	MonitoringMode
currentMode	MonitoringMode
return	void
