Matt Corgan commented on HBASE-7233:
------------------------------------
Yeah - inverse of CellOutputStream is CellScanner, though now thinking it
should not even have the resetToBeforeFirstEntryMethod() for cases where you
can no longer access the beginning of the stream, like when scanning chunks of
cells coming across the wire. CellScanner is basically taking the sequential
access methods of KeyValueScanner, while CellSearcher has the random access
methods. I was thinking they should be separate because you can't always do
random access, like when streaming server->client.
I was leaving them in the prefix-tree module in case we wanted to adapt
KeyValueScanner rather than replacing it. But it looks like you need something
to work with in the mean time, so I'd say using the CellScanner is a good
solution.
I'm not sure about the IOException on CellOutputStream.write() given that the
interface also has the flush() method. Like what does flush do if write is
doing IO? All of my use cases use it more like a buffer/append method where
you are writing it only to memory structures. That being said, looks like
java.io.OutputStream.write() throws it, so i suppose we should follow suit.
