Ivan Habunek commented on LOG4PHP-161:
--------------------------------------
I can see two problems with the above ideas:
1. In both cases, the configurator would have to know how to validate
parameters. Currently, this is not the case, and I would like to keep it that
way. The object which is being configured (appender/filter/whatever) is the
only one which knows how to validate it's own parameters.
2. If one was to programatically configure log4php (without using the
configurator), the parameters should still be validated. For example, if I was
to do this:
$appender = new LoggerAppenderFile();
$appender->setAppend("not a boolean");
I would like the appender to throw a warning, since the "append" property is
boolean.
The only other solution I can see is to do this individually in each setter as
it is done at the moment (in places where it is implemented at all). And this
means a LOT of code recycling.
I'm not a big fan of the base class solution, but it seems as the most
economical one. Why do you think it's such a bad idea?

> Project: Log4php
> Issue Type: Improvement
> Components: Code
> Affects Versions: 2.1
> Reporter: Ivan Habunek
> Labels: configuration, validation
> Fix For: 2.2
>
>
> This includes: appenders, layouts, renderers, filters (and any future ones).
> This is usually implemented in the property setter (sometime in
> activateOptions()). The problem is that the code for checking if something is
> an integer/boolean/string/whatever, and reporting an error is relatively long
> (cca 5-10 lines). We do not want to recycle this code for each and every
> setter.
> The proposed solution is to make a base class from which all configurable
> classes will inherit. This class will provide generic setters which include
> validation and error reporting.
> This is a mockup:

> I believe a solution to this issue should be included in 2.2 to complement
> the new configurator.
