FW: [Fwd: RE: [OJB-developers] Oracle sequences]

[Bischof, R. <rai...@ed...>]

All, 

please find attached an implementation of the High/Low SequenceMgr including
DDL and repository mapping definition.
In order not to re-invent the wheel I decided to extend the default
SequenceMgr. Therefore I had to change some access modifiers in the default
implementation from private to protected. The modified default
implementation is also attached.

Thomas, 
pls have a look and feel free to change whatever is not appropriate for OJB
(the coding conventions for example).

Cheers
Rainer

The OJB SequenceManager is really rather simple (not to say primitive).
The OJB SequenceManager is pluggable. That is, it can easily replaced by
user defined version that implement different semantics (say HIGH/LOW key,
etc.).
See http://objectbridge.sourceforge.net/system/sequencemanager.html on this
subject.
I personally do not intent to implement an improved sequencemanager.
I just can't do ALL the work and want to encourage user contributions to the
OJB codebase.

Thus I'm cc'ing this mail to the OJB developer list. Maybe someone
volunteers for this...

HTH,

Thomas
