Detailed Description

This class is for run-time selection of a frame grabber driver.

This will export the --fg-type=XX command-line option and will instantiate a FrameIstream of the desired type as the option gets assigned a value. As this happens, new options may become available in the command-line. To see them, use --help AFTER you have chosen the type of grabber to use. The current grabber may be retrieved using getFrameGrabber().

Member Function Documentation

nub::soft_ref< FrameIstream > FrameGrabberConfigurator::getFrameGrabber ( ) const

Get the chosen grabber.

You should call this during start() of the ModelComponent that needs the FrameIstream. CAUTION: this may be a null soft_ref if no grabber has been chosen.

Definition at line 61 of file FrameGrabberConfigurator.C.

void FrameGrabberConfigurator::paramChanged	(	ModelParamBase *const	param,
		const bool	valueChanged,
		ParamClient::ChangeStatus *	status
	)			`[protected, virtual]`

Intercept people changing our itsGrabberName ModelParam.

See ModelComponent.H; as parsing the command-line or reading a config file sets our name, we'll also here instantiate a controller of the proper type (and export its options)

Reimplemented from ModelComponent.
