Member Function Documentation

virtual void UaVariableType::arrayDimensions ( UaUInt32Array & arrayDimensions ) const

pure virtual

Get the arrayDimensions value for the passed UaNode.

Parameters

arrayDimensions the arrayDimensions value for the passed UaNode.

Implemented in UaGenericVariableType, and UaVariableTypeSimple.

virtual UaNodeId UaVariableType::dataType ( ) const

pure virtual

Get the DataType for the DataVariable.

Returns: the DataType for the DataVariable.

Implemented in UaGenericVariableType, and UaVariableTypeSimple.

void UaVariableType::getAttributeValue	(	Session *	pSession,
		OpcUa_Int32	attributeId,
