Member Function Documentation

virtual UaStatus HistoryManagerCallback::finishHistoryReadData	(	OpcUa_UInt32	hTransaction,
		OpcUa_UInt32	callbackHandle,
		const UaStatus &	result,
		HistoryReadCPUserDataBase *	pContinuationPoint,
		UaDataValues &	dataValues,
		OpcUa_Boolean	allowThreadUse = OpcUa_False
	)			[pure virtual]

Finishes a historizing ReadData.

Parameters:

	hTransaction	Handle for the transaction used by the SDK to identify the transaction in the callbacks. This handle was passed in to the IOManager with the beginTransaction method.
	callbackHandle	Handle for the node in the callback. This handle was passed in to the IOManager with the beginStopMonitoring 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.
	allowThreadUse	Indicates if the calling thread can be used to send the response if this is the callback for the last node in the transaction.

Returns:

Error code

Implemented in UaTransactionManager.

virtual UaStatus HistoryManagerCallback::finishHistoryReadEvent	(	OpcUa_UInt32	hTransaction,
		OpcUa_UInt32	callbackHandle,
		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 IOManager with the beginTransaction method.
	callbackHandle	Handle for the node in the callback. This handle was passed in to the IOManager with the beginStopMonitoring 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 to send the response if this is the callback for the last node in the transaction.

Returns:

Error code

Implemented in UaTransactionManager.

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 IOManager with the beginTransaction method.
	callbackHandle	Handle for the node in the callback. This handle was passed in to the IOManager with the beginStopMonitoring method.
	result	the result of the current Operation.
	operationResults	the results of an actual operation.
	operationDiagnosticInfos	the diagnsotic information of the current operation.
	allowThreadUse	Indicates if the calling thread can be used to send the response if this is the callback for the last node in the transaction.

Returns:

Error code

Implemented in UaTransactionManager.
