void UaMonitoredItemData::dataChange ( const UaDataValue & dataValue ) [virtual]

Signal a change in value or state.

Parameters:

dataValue the requested Value for this operation.

Implements IOVariableCallback.

OpcUa_DataChangeTrigger UaMonitoredItemData::dataChangeTrigger ( ) const [inline]

Get the data change trigger for the monitored item

OpcUa_Boolean UaMonitoredItemData::discardOldest ( ) const [inline]

Get the discard policy for the monitored item

UaDataValue * UaMonitoredItemData::getChangedValue ( )

Get changed value from item and reset changed flag.

Returns:: the changed value from item and reset changed flag.

virtual UaDataValue UaMonitoredItemData::getLastValue ( ) [inline, virtual]

Get last value send with dataChange.

Implements IOVariableCallback.

OpcUa_Boolean UaMonitoredItemData::hasChanged ( ) [virtual]

Check if the value or status of the item has changed.

Returns:: true if changed false if not.

Implements UaMonitoredItem.

IOManager* UaMonitoredItemData::pIOManager ( ) const [inline]

Get the related IOManager

VariableHandle* UaMonitoredItemData::pVariableHandle ( ) const [inline]

Get the related VariableHandle

OpcUa_UInt32 UaMonitoredItemData::queueSize ( ) [inline]

Get the queue size of the monitored item

void UaMonitoredItemData::setAbsolutDeadband ( OpcUa_Double absoluteDeadband )

Set the absolute deadband for the monitored item.

Parameters:

absoluteDeadband the absolute deadband for the monitored item.

void UaMonitoredItemData::setDataChangeTrigger ( OpcUa_DataChangeTrigger dataChangeTrigger )

Parameters:

dataChangeTrigger the data change trigger for the monitored item.

void UaMonitoredItemData::setDiscardPolicy ( OpcUa_Boolean discardOldest )

Set the discard policy for the monitored item.

Parameters:

discardOldest discards the oldest.

void UaMonitoredItemData::setIOVariableHandle ( OpcUa_UInt32 hIOVariable )

Set the related IOVariable handle.

Parameters:

hIOVariable The handle of the variable in the IOManager created with beginStartMonitoring. The handle was passed to the SDK in the callback finishStartMonitoring.

void UaMonitoredItemData::setMonitoringMode ( OpcUa_MonitoringMode monitoringMode ) [virtual]

Set the Monitoring Mode

Parameters:

monitoringMode the Monitoring Mode

Reimplemented from UaMonitoredItem.
