Member Function Documentation

virtual int AL::ALExtractor::getCurrentPeriod ( )

virtual

Called by the "client" to get the current period chosen by the Extractor.

Returns:: current period

virtual float AL::ALExtractor::getCurrentPrecision ( )

virtual

Called by the "client" to get the current precision chosen by the Extractor.

Returns:: current precision

virtual int AL::ALExtractor::getDefaultPeriod ( )

protectedvirtual

Specifies the advertised period that should be chosen by default when subscribe(std::string name) is used.

Implementing this method is optional. If not implemented, 30 ms will be chosen.

Returns:: info, names and parameters of all subscribers

virtual std::string AL::ALExtractor::httpGet ( )

virtual

Called by the broker webpage to detail the module.

Returns:: an optional extra description of the module

Reimplemented from AL::ALModule.

virtual void AL::ALExtractor::subscribe	(	const std::string &	pSubscribedName,
		const int &	pPeriod,
		const float &	pPrecision
	)

virtual

Called by the "client" to tell that it is interested in the output values.

Parameters:

pSubscribedName	Name of the client module
pPeriod	period of the extractor
pPrecision	precision of the extractor

void AL::ALExtractor::subscribe ( const std::string & pSubscribedName )

Called by the "client" to tell that it is interested in the output values. Period and Precision specified by getDefaultPrecision() and getDefaultPeriod() will be used by default.

Parameters:

pSubscribedName Name of the client module

virtual void AL::ALExtractor::unsubscribe ( const std::string & pSubscribedName )

virtual

Called by the "client" to tell that it is not interested anymore in the output values.

Parameters:

pSubscribedName Name of the client module

virtual void AL::ALExtractor::updatePeriod	(	const std::string &	pSubscribedName,
		const int &	pPeriod
	)

virtual

Called by the "client" to update the periode.

Parameters:

pSubscribedName	Name of the client module
pPeriod	period of the extractor

virtual void AL::ALExtractor::updatePrecision	(	const std::string &	pSubscribedName,
		const float &	pPrecision
	)

virtual

Called by the "client" to update the precision.

Parameters:

pSubscribedName	Name of the client module
pPrecision	precision of the extractor

virtual void AL::ALExtractor::xStartDetection	(	const int	pPeriod,
		const float	pPrecision
	)

protectedpure virtual

What the extractor shall do to start detection.

This method is called only once: when the first module subscribes.

Parameters:

pPeriod	period of the extractor
pPrecision	precision of the extractor

virtual void AL::ALExtractor::xStopDetection ( )

protectedpure virtual

What the extractor shall do to stop detection.

this method is called only once: when the last module unsubscribes.

virtual void AL::ALExtractor::xUpdateParameters	(	const int	pPeriod,
		const float	pPrecision
	)

protectedvirtual

updates fCurrentParameters from fSubscribedList.

This method is called each time the parameters has changed because of a new subscribtion or unsubscription or when a module calls updatePeriod or updatePrecision.

Parameters:

pPeriod	period of the extractor
pPrecision	precision of the extractor
