C# Class MemoryBuffer.MemoryBufferNodeManager

A node manager for a variety of test data.

Inheritance: Opc.Ua.Sample.SampleNodeManager

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.
DeleteAddressSpace ( ) : void	Frees any resources allocated for the address space.
MemoryBufferNodeManager ( IServerInternal server, ApplicationConfiguration configuration ) : System	Initializes the node manager.

Method	Description
CreateMonitoredItem ( ISystemContext context, NodeState source, uint subscriptionId, double publishingInterval, DiagnosticsMasks diagnosticsMasks, TimestampsToReturn timestampsToReturn, MonitoredItemCreateRequest itemToCreate, long &globalIdCounter, MonitoringFilterResult &filterError, IMonitoredItem &monitoredItem ) : ServiceResult	Creates a new set of monitored items for a set of variables. This method only handles data change subscriptions. Event subscriptions are created by the SDK.
DeleteMonitoredItem ( ISystemContext context, IMonitoredItem monitoredItem, bool &processed ) : ServiceResult	Deletes a monitored item.
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.
ModifyMonitoredItem ( ISystemContext context, DiagnosticsMasks diagnosticsMasks, TimestampsToReturn timestampsToReturn, IMonitoredItem monitoredItem, MonitoredItemModifyRequest itemToModify, MonitoringFilterResult &filterError ) : ServiceResult	Modifies the parameters for a monitored item.
SetMonitoringMode ( ISystemContext context, IMonitoredItem monitoredItem, MonitoringMode monitoringMode, bool &processed ) : ServiceResult	Changes the monitoring mode for an 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

CreateMonitoredItem() protected method

Creates a new set of monitored items for a set of variables.

This method only handles data change subscriptions. Event subscriptions are created by the SDK.

protected CreateMonitoredItem ( ISystemContext context, NodeState source, uint subscriptionId, double publishingInterval, DiagnosticsMasks diagnosticsMasks, TimestampsToReturn timestampsToReturn, MonitoredItemCreateRequest itemToCreate, long &globalIdCounter, MonitoringFilterResult &filterError, IMonitoredItem &monitoredItem ) : ServiceResult
context	ISystemContext
source	NodeState
subscriptionId	uint
publishingInterval	double
diagnosticsMasks	DiagnosticsMasks
timestampsToReturn	TimestampsToReturn
itemToCreate	Opc.Ua.MonitoredItemCreateRequest
globalIdCounter	long
filterError	MonitoringFilterResult
monitoredItem	IMonitoredItem
return	Opc.Ua.ServiceResult

DeleteAddressSpace() public method

Frees any resources allocated for the address space.

public DeleteAddressSpace ( ) : void
return	void

DeleteMonitoredItem() protected method

Deletes a monitored item.

protected DeleteMonitoredItem ( ISystemContext context, IMonitoredItem monitoredItem, bool &processed ) : ServiceResult
context	ISystemContext
monitoredItem	IMonitoredItem
processed	bool
return	Opc.Ua.ServiceResult

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

MemoryBufferNodeManager() public method

Initializes the node manager.

public MemoryBufferNodeManager ( IServerInternal server, ApplicationConfiguration configuration ) : System
server	IServerInternal
configuration	ApplicationConfiguration
return	System

ModifyMonitoredItem() protected method

Modifies the parameters for a monitored item.

protected ModifyMonitoredItem ( ISystemContext context, DiagnosticsMasks diagnosticsMasks, TimestampsToReturn timestampsToReturn, IMonitoredItem monitoredItem, MonitoredItemModifyRequest itemToModify, MonitoringFilterResult &filterError ) : ServiceResult
context	ISystemContext
diagnosticsMasks	DiagnosticsMasks
timestampsToReturn	TimestampsToReturn
monitoredItem	IMonitoredItem
itemToModify	Opc.Ua.MonitoredItemModifyRequest
filterError	MonitoringFilterResult
return	Opc.Ua.ServiceResult

SetMonitoringMode() protected method

Changes the monitoring mode for an item.

protected SetMonitoringMode ( ISystemContext context, IMonitoredItem monitoredItem, MonitoringMode monitoringMode, bool &processed ) : ServiceResult
context	ISystemContext
monitoredItem	IMonitoredItem
monitoringMode	MonitoringMode
processed	bool
return	Opc.Ua.ServiceResult
