Detailed Description

Camera factory.

This camera factory provides access to all cameras in a unified way. You just supply a camera argument string and depending on the camera ID and compile-time support of camera types an instance of the desired camera is returned or otherwise an exception is thrown. See instance() for a list of supported camera types.

static C* CameraFactory::instance ( const char *  as  )  [inline, static]

Get typed instance of camera.

Creates a new instance and converts it to the requested type. If the type does not match the requested camera an exception is thrown.

Parameters:
as camera argument string
Returns:
typed camera instance
Exceptions:
TypeMismatchException thrown, if requested camera does not match requested type.

Camera * CameraFactory::instance ( const CameraArgumentParser *  cap  )  [static]

Get camera instance with parameters from given camera argument parser.

This is a convenience method and works like instace(const char *as).

Parameters:
cap camera argument parser
Returns:
camera instance
Exceptions:
UnknownCameraTypeException thrown if camera type is not known or was not available at build time.

C * CameraFactory::instance ( const char *  as  )  [inline, static]

Get camera instance.

Get an instance of a camera of the given type. The argument string determines the type of camera to open. Supported camera types:

  • firewire, FirewireCamera, compiled if HAVE_FIREWIRE_CAM is defined in fvconf.mk
  • leutron, LeutronCamera, compiled if HAVE_LEUTRON_CAM is defined in fvconf.mk
  • file, FileLoader, compiled if HAVE_FILELOADER_CAM is defined in fvconf.mk
  • shmem, SharedMemoryCamera, compiled if HAVE_SHMEM_CAM is defined in fvconf.mk
  • net, NetworkCamera, compiled if HAVE_NETWORK_CAM is defined in fvconf.mk
  • v4l, V4LCamera, compiled if HAVE_V4L_CAM is defined in fvconf.mk
    Parameters:
    as camera argument string
    Returns:
    camera instance of requested type
    Exceptions:
    UnknownCameraTypeException thrown, if the desired camera could not be instantiated. This could be either to a misspelled camera ID, generally missing support or unset definition due to configuration in fvconf.mk or missing libraries and camera support compile-time autodetection.
