[Babeldoc-devel] Rationalising LightConfig and SqlConfig

[Michael A. <mic...@ze...>]

Hi, all,

It seems to me that LightConfig and SqlConfig could be rationalised into
a single Config class.  This would mean adding two methods to the
IConfigService interface: setConfig(String key, String value) and
setConfig(String name, String value, Locale locale).  What this means is
that the IConfigService interface implies updatability.  In the case of
LightConfigService, this could simply throw a NotImplemented exception.

I think the implementations of both LightConfig and SqlConfig are very
generic, and I think the linkage between each of them and their services
(LightConfigService and SqlConfigService) would be clarified by this
change.  Also, it codifies the principle that the service is changeable,
while the config structure isn't, i.e.: no matter which config service
you use, the actual config structures stay the same.

The rationalised Config class could be extended if necessary to take new
functionality into account, but at least would provide a reasonable
default implementation, which could probably be used for any new service
types that might be written.

Thoughts, ideas, pros, cons?
