Detailed Description

Grabber class that grabs images from SharedMemorySegment instances.

Images that are published using the SharedMemoryPublisher can be grabbed with this grabber type. Please don't use this Grabber class directly, but instantiate GenericGrabber with Devide type 'sm'.

icl::io::SharedMemoryGrabber::SharedMemoryGrabber

(

const std::string &

sharedMemorySegmentID = ""

Member Function Documentation

virtual const core::ImgBase* icl::io::SharedMemoryGrabber::acquireImage

(

)

[virtual]

grabbing function

grab function calls the Grabber-specific acquireImage-method and applies distortion if necessary

If dst is not NULL, it is exploited and filled with image data

Reimplemented from icl::io::Grabber.

static const std::vector<GrabberDeviceDescription>& icl::io::SharedMemoryGrabber::getDeviceList

(

bool

rescan

)

[static]

returns a list of all available shared-memory image-streams

void icl::io::SharedMemoryGrabber::init

(

const std::string &

sharedMemorySegmentID

)

throw (utils::ICLException) [private]

Connects an unconnected grabber to given shared memory segment.

void icl::io::SharedMemoryGrabber::processPropertyChange

(

const utils::Configurable::Property &

prop

)

callback for changed configurable properties

Reimplemented from icl::io::Grabber.

static void icl::io::SharedMemoryGrabber::resetBus

(

bool

verbose

)

[static]

resets all 'shared-memory-segents and system-semaphores'
