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
	)

Constructs a CacheVariableConnector object.

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
