Detailed Description

Class connecting a UaVariableCache object with a monitoring item.

This class is used to connect a UaVariableCache object with a monitored item for sampling data by implementing the interfaces CacheSignal and SamplingEngine

Constructor & Destructor Documentation

CacheVariableConnector::CacheVariableConnector	(	OpcUa_Int32	samplingInterval,
		UaVariableCache *	pUaVariableCache,
		IOVariableCallback *	pIOVariableCallback,
		Session *	pSession
	)

Parameters:

[in]	samplingInterval	This interval defines the sampling rate of the monitored item
[in]	pUaVariableCache	UaVariableCache used in the monitored item
[in]	pIOVariableCallback	Callback interface for data changes
[in]	pSession	Session object responsible for the sampling item

CacheVariableConnector::~CacheVariableConnector ( ) [virtual]

OpcUa_UInt32 CacheVariableConnector::getSamplingRate ( ) [virtual]

Get the sampling rate of the item

Implements CacheSignal.

UaVariableCache* CacheVariableConnector::pUaVariableCache ( ) [inline]

Get UaVariableCache used for the variable

void CacheVariableConnector::sample ( ) [virtual]

Sample signal for the item

void CacheVariableConnector::setChanged ( ) [virtual]

Signal a change in value or state

Implements CacheSignal.

void CacheVariableConnector::setInvalid ( ) [virtual]

Set the item invalid

Implements CacheSignal.

void CacheVariableConnector::setSamplingRate ( OpcUa_UInt32 samplingRate ) [inline]

Set the sampling rate of the item

Parameters:

samplingRate the sampling Rate in Milliseconds.
