Constructor & Destructor Documentation

pcl::PCDGrabberBase::PCDGrabberBase	(	const std::string &	pcd_file,
		float	frames_per_second,
		bool	repeat
	)

Constructor taking just one PCD file.

Parameters:

[in]	pcd_file	path to the PCD file
[in]	frames_per_second	frames per second. If 0, start() functions like a trigger, publishing the next PCD in the list.
[in]	repeat	whether to play PCD file in an endless loop or not.

pcl::PCDGrabberBase::PCDGrabberBase	(	const std::vector< std::string > &	pcd_files,
		float	frames_per_second,
		bool	repeat
	)

Constuctor taking a list of paths to PCD files, that are played in the order the appear in the list.

Parameters:

pcd_files	vector of paths to PCD files.
frames_per_second	frames per second. If 0, start() functions like a trigger, publishing the next PCD in the list.
repeat	whether to play PCD file in an endless loop or not.

Member Function Documentation

virtual float pcl::PCDGrabberBase::getFramesPerSecond

(

)

const [virtual]

returns the frames_per_second.

0 if grabber is trigger-based

Implements pcl::Grabber.

virtual std::string pcl::PCDGrabberBase::getName

(

)

const [virtual]

Returns:

name of the grabber

Implements pcl::Grabber.

bool pcl::PCDGrabberBase::isRepeatOn

(

)

const

returns whether the repeat flag is on

virtual bool pcl::PCDGrabberBase::isRunning

(

)

const [virtual]

whether the grabber is started (publishing) or not.

Returns:

true only if publishing.

Implements pcl::Grabber.

template<typename T >

bool pcl::Grabber::providesCallback

(

)

const [inherited]

indicates whether a signal with given parameter-type exists or not

Returns:

true if signal exists, false otherwise

Definition at line 261 of file grabber.h.

template<typename T >

boost::signals2::connection pcl::Grabber::registerCallback

(

const boost::function< T > &

callback

)

[inherited]

registers a callback function/method to a signal with the corresponding signature

Parameters:

[in]

callback,:

the callback function/method

Returns:

Connection object, that can be used to disconnect the callback method from the signal again.

Definition at line 232 of file grabber.h.

virtual void pcl::PCDGrabberBase::rewind

(

)

[virtual]

rewinds to the first PCD file in the list.

virtual void pcl::PCDGrabberBase::start

(

)

[virtual]

starts playing the list of PCD files if frames_per_second is > 0.

Otherwise it works as a trigger: publishes only the next PCD file in the list.

Implements pcl::Grabber.

virtual void pcl::PCDGrabberBase::stop

(

)

[virtual]

stops playing the list of PCD files if frames_per_second is > 0.

Otherwise the method has no effect.

Implements pcl::Grabber.

virtual void pcl::PCDGrabberBase::trigger

(

)

[virtual]

triggers a callback with new data
