Look at merging the interfaces PositionedStream and Resetable into one
----------------------------------------------------------------------
Key: DERBY-4002
URL: https://issues.apache.org/jira/browse/DERBY-4002
Project: Derby
Issue Type: Task
Components: JDBC, Store
Affects Versions: 10.5.0.0
Reporter: Kristian Waagan
Priority: Minor
>From DERBY-3935:
"By the way, would it make sense at some point to merge the PositionedStream
interface with Resetable? Or perhaps make PositionedStream extend Resetable?
Resetable.resetStream() is just a special case of
PositionedStream.reposition(), and it seems like both PositionStoreStream and
LOBInputStream have methods that match the functionality defined by Resetable
(PSS actually implements Resetable)."
and
"Regarding Resetable and PositionedStream (PS), the former is more tightly
bound to store.
For instance, initStream handles locking, which is probably not required for
data streams outside of store. I don't see any immediate need to add the three
methods resetStream, initStream and closeStream to LOBInputStream.
I'm opting for committing what I have now, and look at combining the interfaces
later if it turns out that is the best thing to do."
Note that this task may also conclude that the two interfaces shouldn't be
merged, but if so the rationale should be documented under this issue.
