Constructor & Destructor Documentation

HDLGrabber() [1/2]

pcl::HDLGrabber::HDLGrabber ( const std::string & correctionsFile = "",
const std::string & pcapFile = ""
)

Constructor taking an optional path to an HDL corrections file.

The Grabber will listen on the default IP/port for data packets [192.168.3.255/2368]

Parameters
[in] correctionsFile Path to a file which contains the correction parameters for the HDL. This parameter is mandatory for the HDL-64, optional for the HDL-32
[in] pcapFile Path to a file which contains previously captured data packets. This parameter is optional

HDLGrabber() [2/2]

pcl::HDLGrabber::HDLGrabber ( const boost::asio::ip::address & ipAddress,
const std::uint16_t port,
const std::string & correctionsFile = ""
)

Constructor taking a specified IP/port and an optional path to an HDL corrections file.

Parameters
[in] ipAddress IP Address that should be used to listen for HDL packets
[in] port UDP Port that should be used to listen for HDL packets
[in] correctionsFile Path to a file which contains the correction parameters for the HDL. This field is mandatory for the HDL-64, optional for the HDL-32

~HDLGrabber()

pcl::HDLGrabber::~HDLGrabber ( )
noexcept

virtual Destructor inherited from the Grabber interface.
