OGF.22 SAGA-SESSION I: Java Language Bindings
When: 9:30 - 11:00 What:
- IPR - sessions during this OGF - agenda accepted
- SAGA spec landscape
- design choices
Q: Malcolm: on what level should concurrency be? Every call? A: yes. But not enforcing execution order
Q: why IOException, not SAGA_IO_Exception? A: lets check... - yep, should do
Q: where are infos encoded in ERRNO? A: inside the exception. Extra field?
Q: no permissions? really? A: yes, really. ;-)
Note: Java-7 will have permissions.
- interfaces & factories
Q: Malcolm: with boostrap loader, you can't mix two implementations in one VM A: right. We discussed this, but cuold not find a sensible use case... A: Daniel: Actually, does not prevent that, as you can use multiple class loaders
Q: Hidemoto: Which ways to set that property? A: usual Java ways...
Q: Why not have session.createFile (URL) 'Solves' the default session problem (missing) looks simple gives same signature for both versions A: Hmm, why not...
- SAGAObject
Q: do you need getType A: could use isInstanceOf
- saga.error
Q: SagaError? What is the supposed action? Q: Daniel: do NOT call it an Error A: Hmmm... Yep, could use NoSuccess If not, discuss again on mailing list.
Q: Hidemoto: add 'Exception' to names. Q: Exception -> SAGAException Q: move exceptions to org.ogf.saga? A: possibly yes to all of them
- tasks:
Q: task container: possibly get_task_type (cookie)? A: not possible
- job
Q: Daniel: Task<Object> -> Task<?extendsObject> A: aha
- buffer
Q: can you have impl managed buffers? A: yes
Q: Thilo: should we use java.nio.ByteBuffer A: Hmm, dunno.
Q: buffer should have long for size? A: yes
- summary
Q: open points? A: address all 'binding issue' tags in the core spec
Q: intro sections? A: remove intros if semantics is the same A: Daniel: keep it so user does not need to jump so often
-> tough call, probably should keep it.
Q: Shantenu: how many people intent to use that spec? A: not many....
