Add seek to FileIO via RandomAccessInputStream and BufferedInputStream,
by introducing a Seek() API to those implementations. Seek is different
than SkipNBytes in that you can Seek backwards, whereas on a stream,
you can only move forwards. While Seek() on RandomAccessInputStream
sort of makes sense, Seek() on BufferedInputStream makes a little less
sense. I avoided adding Seek() to the InputStreamInterface because I didn't
want all implementors of InputStreamInterface to have to implement Seek(),
only those for which it made some sense. However, I did have to add
a Reset() API to InputStreamInterface to allow reseting + skipping as the
method of seeking backwards.
Adds read(n) to FileIO. Defaults to 'read to the end of the file' as
usual, and allows reading n bytes.
This change is to help enable FileIO to be used as a fileobj for gzipfile,
among other things.
