virtual float pcl::Grabber::getFramesPerSecond ( ) const

pure virtual

returns fps.

0 if trigger based.

Implemented in pcl::HDLGrabber, pcl::OpenNIGrabber, pcl::PCDGrabberBase, pcl::ImageGrabberBase, pcl::ONIGrabber, pcl::PXCGrabber, pcl::DinastGrabber, and pcl::RobotEyeGrabber.

virtual std::string pcl::Grabber::getName ( ) const

pure virtual

returns the name of the concrete subclass.

Returns

the name of the concrete driver.

Implemented in pcl::HDLGrabber, pcl::OpenNIGrabber, pcl::PCDGrabberBase, pcl::ImageGrabberBase, pcl::PXCGrabber, pcl::ONIGrabber, pcl::RobotEyeGrabber, and pcl::DinastGrabber.

virtual bool pcl::Grabber::isRunning ( ) const

pure virtual

Indicates whether the grabber is streaming or not.

This value is not defined for triggered devices.

Returns

true if grabber is running / streaming. False otherwise.

Implemented in pcl::HDLGrabber, pcl::OpenNIGrabber, pcl::ONIGrabber, pcl::PCDGrabberBase, pcl::ImageGrabberBase, pcl::PXCGrabber, pcl::RobotEyeGrabber, and pcl::DinastGrabber.

template<typename T >

bool pcl::Grabber::providesCallback

(

)

const

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

Returns

true if signal exists, false otherwise

Definition at line 264 of file grabber.h.

template<typename T >

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

(

const boost::function< T > &

callback

)

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.

virtual void pcl::Grabber::signalsChanged ( )

inlineprotectedvirtual

Reimplemented in pcl::OpenNIGrabber.

Definition at line 112 of file grabber.h.

virtual void pcl::Grabber::start ( )

pure virtual

For devices that are streaming, the streams are started by calling this method.

Trigger-based devices, just trigger the device once for each call of start.

Implemented in pcl::HDLGrabber, pcl::OpenNIGrabber, pcl::PXCGrabber, pcl::PCDGrabberBase, pcl::ONIGrabber, pcl::ImageGrabberBase, pcl::DinastGrabber, and pcl::RobotEyeGrabber.

virtual void pcl::Grabber::stop ( )

pure virtual

For devices that are streaming, the streams are stopped.

This method has no effect for triggered devices.

Implemented in pcl::HDLGrabber, pcl::OpenNIGrabber, pcl::ONIGrabber, pcl::PXCGrabber, pcl::PCDGrabberBase, pcl::ImageGrabberBase, pcl::DinastGrabber, and pcl::RobotEyeGrabber.
