Detailed Description

Helper class for the EventManager interface implementation in EventManagerBase.

This class is used to represent an event filter element in the EventFilter class.

Constructor & Destructor Documentation

EventFilterOperand::EventFilterOperand ( )

Constructs an event filter operand object.

EventFilterOperand::~EventFilterOperand ( )

Destroys the event filter operand object

OpcUa_Boolean EventFilterOperand::boolValue	(	UaEventData *	pEventData,
		Session *	pSession,
		OpcUa_Boolean &	isNull
	)

Tries to resolve the operand to an boolean value. Returns NULL indicated by the isNull flag if this is not possible.

Parameters:

[in]	pEventData	Event data for the new event
[in]	pSession	Session context for the event monitored item
[in]	isNull	Flag indicating if the operand can not be resolved to a boolean value and the result is NULL

UaVariant EventFilterOperand::value	(	UaEventData *	pEventData,
		Session *	pSession
	)

Returns the operand value
