Public Member Functions
virtual	~ArtificialSignalSource ()
	Destructor.
virtual SampleBlock< double >	getSyncData ()
	Method to achieve synchronous data acquisition (method is blocking).
virtual SampleBlock< double >	getAsyncData ()
	Method to achieve asynchronous data acquisition (method is non-blocking).
Protected Member Functions
	ArtificialSignalSource (boost::asio::io_service &io, ticpp::Iterator< ticpp::Element > hw)
	Constructor for initialization with an XML object.
virtual void	run ()
	Method to start data acquisition.
virtual void	stop ()
	Method to stop data acquisition.
void	init ()
	Method initializing the artificial signal source object.
virtual void	setHardware (ticpp::Iterator< ticpp::Element >const &hw)=0
	Set the configuration of the SineGenerator with a XML object.
virtual void	generateSignal ()=0
	Abstract method generating the artificial signal.
virtual void	setDeviceSettings (ticpp::Iterator< ticpp::Element >const &father)=0
	Set configuration listed in the <device_settings> section in the XML file.
virtual void	setChannelSettings (ticpp::Iterator< ticpp::Element >const &father)=0
	Set configuration listed in the <channel_settings> section in the XML file.
Protected Attributes
