UaStatus ServerManager::browse	(	const UaNodeId &	startingNode,
		const UaNodeId &	referenceTypeFilter,
		ContinuationPointWrapper &	continuationPoint,
		UaReferenceDescriptions &	references
	)

Browse function for internal use for forward browsing.

This method provides a simplified browse function for internal use. It uses the normal NodeManager::browse but hides the handling that is necessary for the remote access from a client.

This version of the simplified browse is browsing forward and returns all node classes.

Returns:: Status result code for the call.

Parameters:

[in]	startingNode	Starting node for the browse call
[in]	referenceTypeFilter	Reference type filter to return only nodes referenced from the starting node with this reference type or a subtype
[in,out]	continuationPoint	Continuation point for the browse. Indicates if more results are available
[out]	references	List of browse results for the browsed node

UaStatus ServerManager::browse	(	const UaNodeId &	startingNode,
		OpcUa_Boolean	isInverse,
		const UaNodeId &	referenceTypeFilter,
		OpcUa_UInt32	nodeClassMask,
		ContinuationPointWrapper &	continuationPoint,
		UaReferenceDescriptions &	references
	)

Browse function for internal use.

This method provides a simplified browse function for internal use. It uses the normal NodeManager::browse but hides the handling that is necessary for the remote access from a client.

Returns:: Status result code for the call.

Parameters:

[in]	startingNode	Starting node for the browse call
[in]	isInverse	Flag indicating if the browse is inverse (True) or forward (False)
[in]	referenceTypeFilter	Reference type filter to return only nodes referenced from the starting node with this reference type or a subtype
[in]	nodeClassMask	Node class filter mask identifing the node classes to include in the browse result Bit mask containing the following options: OpcUa_NodeClass_Object = 1 OpcUa_NodeClass_Variable = 2 OpcUa_NodeClass_Method = 4 OpcUa_NodeClass_ObjectType = 8 OpcUa_NodeClass_VariableType = 16 OpcUa_NodeClass_ReferenceType = 32 OpcUa_NodeClass_DataType = 64 OpcUa_NodeClass_View = 128 If set to zero, all node classes are returned.
[in,out]	continuationPoint	Continuation point for the browse. Indicates if more results are available
[out]	references	List of browse results for the browsed node

UaStatus ServerManager::call	(	Session *	pSession,
		const UaNodeId &	objectId,
		const UaNodeId &	methodId,
		const UaVariantArray &	inputArguments,
		UaStatusCodeArray &	inputArgumentResults,
		UaVariantArray &	outputArguments
	)

Internal function to call a method.

Returns:: Status result code for the call.

Parameters:

[in]	pSession	Session context for the function call
[in]	objectId	Object node for the call
[in]	methodId	Method node for the call
[in]	inputArguments	Array of input arguments
[out]	inputArgumentResults	Array of input argument results
[out]	outputArguments	Array of output argumens

void ServerManager::changeServerState ( OpcUa_ServerState newState )

Change the server state represented in the address space.

This method allows the application to change the server state if the state is not longer running or to change the stat back to running after an error situation.

Parameters:

[in] newState New server status

UaStatus ServerManager::createDataMonitoredItems	(	Session *	pSession,
		DataMonitoredItemSpecArray &	dataMonitoredItems
	)

Internal function to create a list of data monitored items.

Returns:: Status result code for the call.

Parameters:

[in]	pSession	Session context for the function call
[in,out]	dataMonitoredItems	Array of DataMonitoredItemSpec objects containing the information for the creation in a data monitored item.

UaStatus ServerManager::createEventMonitoredItem	(	Session *	pSession,
		const UaNodeId &	objectToMonitor,
		EventCallback *	pEventCallback,
		OpcUa_EventFilter *	pEventFilter,
		OpcUa_UInt32 &	monitoredItemId
	)

Internal function to create an event monitored item.

Returns:: Status result code for the call.

Parameters:

[in]	pSession	Session context for the function call
[in]	objectToMonitor	Object node used as event notifier
[in]	pEventCallback	Event callback interface for the event monitored item
[in]	pEventFilter	Event filter for the monitored item
[out]	monitoredItemId	Id of the created monitored item

NodeManager * ServerManager::createNodeManagerNS1 ( const UaString & sServerUri ) [protected, virtual]

This function creates the NodeManagerNS1. The virtual function can be overwritten by a derived class to create a class derived from NodeManagerNS1 instead of NodeManagerNS1 An instance of a derived class of ServerManager can be passed to CoreModule::initialize() to force the CoreModule to use this instance instead of creating a ServerManager

SessionManager * ServerManager::createSessionManager ( ) [protected, virtual]

This function creates the SessionManager. The virtual function can be overwritten by a derived class to create a class derived from SessionManager instead of SessionManager. An instance of a derived class of ServerManager can be passed to CoreModule::initialize() to force the CoreModule to use this instance instead of creating a ServerManager

UaStatus ServerManager::deleteMonitoredItems	(	Session *	pSession,
		const UaUInt32Array &	monitoredItemIds,
		UaStatusCodeArray &	results
	)

Internal function to delete a list of monitored items.

void ServerManager::registerDynamicEventManager ( EventManager * pEventManager )

Inform the server manager about a new event manager added after server start up.

EventManagers can be responsible for information requests from clients even if they are created after the client initiated the request. This happes especially if a client is interested in all events from the server and a new event manager is added. This method allows an EventManager to get informed about already created event subscriptions.

Parameters:

[in] pEventManager New and dynamically added EventManager

Parameters:

[in]	secondsTillShutdown	Seconds till shutdown of the server
[in]	shutdownReason	Reason for the shutdown

UaStatus ServerManager::startUp ( ServerConfig * pServerConfig )

		const UaWriteValues &	nodesToWrite,
		UaStatusCodeArray &	results
	)

Write function for internal use.
