Subject Proposal to factor Common code in James Protocol Servers into AbstractService.
Date Wed, 02 May 2001 12:11:44 GMT
There is a some common code in


All of these classes derive from

If the base class handled <configure> then the only code needed would be
implementation of
    protected ConnectionHandlerFactory createFactory();

I don't think this vastly improves the James system but it would have these
- duplication would be removed. This would mean consistent behaviour and
better maintainability.
- If the code could be factored into Avalon, other prototocol servers that
are not related to James but do similar things to POP, SMTP etc. could reuse
the same pattern.
- Avalon Stack will be more full featured and would capture the code pattern
better. This may make Avalon more attractive.

Here is a specific proposal.
a) have AbstractService handle configure and any other code in James
protocol servers for logging etc.
b) James protocol servers POP3Server etc. will only implement 1 method
<createFactory>. Nothing else.

This is not directly related to the 'Logging' emails but, but by reducing
code it would be easier to spot inconsistencies.

thoughts, votes ?
