ConcurrentQueue &	events (const std::size_t n=0)
	Read a given number of events, add them to the queue, and return it.
void	prefetch (const std::size_t n)
	Keep the queue at a given number of events from a background thread.
std::size_t	prefetchCapacity () const
	Number of events prefetch() keeps in the queue.
void	reset ()
	Go back to the beginning, discarding the events in the queue.
void	setTimeTransform (const TimeType offset, const TimeType scale=1)
	Transform the timestamp of every event read from now on as (t - offset) * scale.
void	setRoi (const cv::Rect &roi)

Detailed Description

This class extends AbstractReader_ to read event data from HDF5 files.

// Default paths match the common /events/{t,x,y,p} layout:
ev::HDF5Reader reader("recording.h5");
 
// Custom paths:
ev::HDF5Reader reader("recording.h5",
                      "/davis/left/events/timestamp",
                      "/davis/left/events/x",
                      "/davis/left/events/y",
                      "/davis/left/events/polarity");
