Dimitri Vorona commented on ARROW-2816:
---------------------------------------
Hi Antoine. Since RawIOBase is an ABC, couldn't we just register NativeFile
with it, after we've added all the methods? Should take care of any instanceof
checks.
> [Python] Add __iter__ method to NativeFile

> Currently, NativeFile does not pass the check of pandas for being a
> "file-like" object because it does not have __iter__ method. It can be easily
> added using code from native python io module as a reference. Another way
> would be to subclass io.IOBase.
> The exact code of pandas check can be found here.
> Code for __iter__ method and io.IOBase can be found here.
