UaStatus InternalDurableSubscriptionCallback::finishModifyMonitoring	(	OpcUa_UInt32	hTransaction,
		OpcUa_UInt32	callbackHandle,
		OpcUa_Double	revisedSamplingInterval,
		const UaStatus &	statusCode
	)

inlinevirtual

Finished modify monitoring of an attribute value of a node.

The method is called to finish the modifying of the sampling attributes for a monitored item. The modifying is started with the beginModifyMonitoring method of the interface IOManager.

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 beginModifyMonitoring method.
revisedSamplingInterval	The corresponding revised sampling interval for the requested sampling interval in beginModifyMonitoring.
statusCode	Result of the ModifyMonitoring operation. Optional diagnostig information requested by the client in the parameter ServiceContext::returnDiagnostics of IOManager::beginTransaction can be provided through UaStatus::setDiagnosticInfo().

Returns: Error code

Implements IOManagerCallback.

		OpcUa_UInt32	callbackHandle,
		OpcUa_UInt32	eventManagerIndex,
		OpcUa_Double	revisedSamplingInterval,
		const UaStatus &	statusCode,
		OpcUa_EventFilterResult *	pEventFilterResult
	)

inlinevirtual

Finished transaction to modify monitoring an event item.

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 EventManager with the beginModifyMonitoring method.
eventManagerIndex	an Index of different EventManagers.
revisedSamplingInterval	The corresponding revised sampling interval for the requested sampling interval in beginModifyMonitoring.
statusCode	Result of the ModifyMonitoring operation.
pEventFilterResult	Detailed result for the event filter. Can be NULL if no error occurred. The SDK detaches the result content.

Returns: Result code of the method call

Implements EventManagerCallback.

		OpcUa_UInt32	callbackHandle,
		UaDataValue &	dataValue,
		OpcUa_Boolean	detachValue,
		OpcUa_Boolean	allowThreadUse,
		UaDiagnosticInfo *	pDiagnosticInfo
	)

inlinevirtual

Finished reading of an attribute value of a node.

The method is called to finish a read call for an attribute value of a node. The read is started with the beginRead method of the interface IOManager.

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 beginRead method.
dataValue	Contains the value, timestamps and result code for the Read operation.
detachValue	Indicates if the method can detach the value from the wrapper class.
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.
pDiagnosticInfo	Optional diagnostig information requested by the client in the parameter ServiceContext::returnDiagnostics of IOManager::beginTransaction

Returns: Error code

Implements IOManagerCallback.

		OpcUa_Boolean	initialDataValueAvailable,
		const UaDataValue &	initialDataValue,
		const UaStatus &	statusCode
	)

virtual

Finished transaction to start monitoring a data item.

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 beginStartMonitoring method.
hIOVariable	The handle of the variable in the IOManager created with beginStartMonitoring. The handle was passed to the SDK in the callback finishStartMonitoring.
revisedSamplingInterval	The corresponding revised sampling interval for the requested sampling interval in beginStartMonitoring.
initialDataValueAvailable	the available initial data value.
initialDataValue	the actual data value.
statusCode	Result of the finishStartMonitoring operation.

Returns: Error code

Implements IOManagerCallback.
