pure virtual

Callback function for a historical read of data.

Parameters

hTransaction	Handle for the transaction used by the SDK to identify the transaction in the callbacks. This handle was passed in to the HistoryManager with the beginHistoryTransaction method.
callbackHandle	Handle for the node in the callback. This handle was passed in to the HistoryManager with either beginReadRawModified, beginReadProcessed or beginReadAtTime.
result	The result of the current Operation.
pContinuationPoint	The continuation point data if not all results can be returned in one Read call. Implementers of this interface can store the continuation point data in a derived class.
dataValues	The requested Values for this operation. The values array will be detached by the SDK.
allowThreadUse	Indicates if the calling thread can be used by the SDK to send the response to the client. This can happen if this method is the called for the last node in the transaction. True: The thread calling this method can be used to send the response and may block False: The SDK is using a worker thread to send the response to the client.

		const UaStatus &	result,
		HistoryReadCPUserDataBase *	pContinuationPoint,
		UaHistoryEventFieldLists &	events,
		OpcUa_Boolean	allowThreadUse = `OpcUa_False`
	)

pure virtual

Finishes a historizing ReadEvent.

Parameters

hTransaction	Handle for the transaction used by the SDK to identify the transaction in the callbacks. This handle was passed in to the HistoryManager with the beginHistoryTransaction method.
callbackHandle	Handle for the node in the callback. This handle was passed in to the HistoryManager with the beginReadEvents method.
result	the result of the current Operation.
pContinuationPoint	The continuation point data if not all results can be returned in one Read call. Implementers of this interface can store the continuation point data in a derived class.
events	a list of events that match the read filter. The event array will be detached by the SDK.
allowThreadUse	Indicates if the calling thread can be used by the SDK to send the response to the client. This can happen if this method is the called for the last node in the transaction. True: The thread calling this method can be used to send the response and may block False: The SDK is using a worker thread to send the response to the client.

virtual UaStatus HistoryManagerCallback::finishHistoryReadModifiedData	(	OpcUa_UInt32	hTransaction,
		OpcUa_UInt32	callbackHandle,
		const UaStatus &	result,
		HistoryReadCPUserDataBase *	pContinuationPoint,
		UaDataValues &	dataValues,
		UaModificationInfo &	modificationInformations,
		OpcUa_Boolean	allowThreadUse = `OpcUa_False`
	)

pure virtual

Callback function for a historical read of modified data.

Parameters

hTransaction	Handle for the transaction used by the SDK to identify the transaction in the callbacks. This handle was passed in to the HistoryManager with the beginHistoryTransaction method.
callbackHandle	Handle for the node in the callback. This handle was passed in to the HistoryManager with the beginReadRawModified method.
result	The result of the current Operation.
pContinuationPoint	The continuation point data if not all results can be returned in one Read call. Implementers of this interface can store the continuation point data in a derived class.
dataValues	The requested Values for this operation. The values array will be detached by the SDK.
modificationInformations	The modification information for the requested Values for this operation. The information array will be detached by the SDK.
allowThreadUse	Indicates if the calling thread can be used by the SDK to send the response to the client. This can happen if this method is the called for the last node in the transaction. True: The thread calling this method can be used to send the response and may block False: The SDK is using a worker thread to send the response to the client.

virtual UaStatus HistoryManagerCallback::finishHistoryUpdate	(	OpcUa_UInt32	hTransaction,
		OpcUa_UInt32	callbackHandle,
		const UaStatus &	result,
		UaStatusCodeArray &	operationResults,
		UaDiagnosticInfos &	operationDiagnosticInfos,
		OpcUa_Boolean	allowThreadUse = `OpcUa_False`
	)

pure virtual

Finishes a historizing Update.

Parameters

hTransaction	Handle for the transaction used by the SDK to identify the transaction in the callbacks. This handle was passed in to the HistoryManager with the beginHistoryTransaction method.
callbackHandle	Handle for the node in the callback. This handle was passed in to the HistoryManager with either beginUpdateData, beginUpdateEvents, beginDeleteRawModified, beginDeleteAtTime or beginDeleteEvents.
result	the result of the current Operation.
operationResults	The results for the requested updates.
operationDiagnosticInfos	The diagnostic for the requested updates.
allowThreadUse	Indicates if the calling thread can be used by the SDK to send the response to the client. This can happen if this method is the called for the last node in the transaction. True: The thread calling this method can be used to send the response and may block False: The SDK is using a worker thread to send the response to the client.
