Detailed Description

Wrapper class for the OPC UA EventFilter structure

The EventFilter provides for the filtering and content selection of Event Subscriptions. If an Event Notification conforms to the filter defined by the where parameter of the EventFilter, then the Notification is sent to the Client. Each Event Notification includes the fields defined by the selectClauses parameter of the EventFilter.

void UaEventFilter::detachFilter

(

OpcUa_ExtensionObject &

filter )

Creates the extension object for the filter and detaches the EventFilter data to the extension object.

void UaEventFilter::setSelectClauseElement	(	OpcUa_UInt32	index,
		const UaSimpleAttributeOperand &	selectElement,
		OpcUa_UInt32	arraySize
	)

Sets one element of the event filter select clause.

The select clause is composed of an array of SimpleAttributeOperands.

void UaEventFilter::setWhereClause

(

UaContentFilter *

pWhereClause )

Sets the where clause of the event filter.

The passed content filter will be deleted by the UaEventFilter. If an Event Notification conforms to the filter defined by the where parameter of the EventFilter, then the Notification is sent to the Client.
