Methods Documentation

close()

write_frame(data, header=None, **kwargs)

Write a single frame (header plus payload).

Parameters:

data : ndarray or VDIFFrame

If an array, a header should be given, which will be used to get the information needed to encode the array, and to construct the VDIF frame.

header : VDIFHeader

Can instead give keyword arguments to construct a header. Ignored if data is a VDIFFrame instance.

**kwargs

If header is not given, these are used to initialize one.

write_frameset(data, header=None, **kwargs)

Write a single frame set (headers plus payloads).

Parameters:

data : ndarray or VDIFFrameSet

If an array, a header should be given, which will be used to get the information needed to encode the array, and to construct the VDIF frame set.

header : VDIFHeader, list of same

Can instead give keyword arguments to construct a header. Ignored if data is a VDIFFrameSet instance. If a list, should have a length matching the number of threads in data; if a single header, thread_ids corresponding to the number of threads are generated automatically.

**kwargs

If header is not given, these are used to initialize one.
