Constructor & Destructor Documentation

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

Constructor taking just one PCD file or one TAR file containing multiple PCD files.

Parameters
[in]pcd_filepath to the PCD file
[in]frames_per_secondframes per second. If 0, start() functions like a trigger, publishing the next PCD in the list.
[in]repeatwhether 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 
)

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

Parameters
[in]pcd_filesvector of paths to PCD files.
[in]frames_per_secondframes per second. If 0, start() functions like a trigger, publishing the next PCD in the list.
[in]repeatwhether to play PCD file in an endless loop or not.
pcl::PCDGrabberBase::PCDGrabberBase ( const PCDGrabberBase src)
inline

Copy constructor.

Parameters
[in]srcthe PCD Grabber base object to copy into this

Definition at line 78 of file pcd_grabber.h.

virtual pcl::PCDGrabberBase::~PCDGrabberBase ( ) throw ()
virtual

Virtual destructor.

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
The 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.

PCDGrabberBase& pcl::PCDGrabberBase::operator= ( const PCDGrabberBase src)
inline

Copy operator.

Parameters
[in]srcthe PCD Grabber base object to copy into this

Definition at line 87 of file pcd_grabber.h.

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 265 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 236 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.
