Appenders
Hi,
I would love to have a direct access to the target of a ConsoleAppender (as
I can directly get the fileName of a FileAppender). Do you plan to
implement this feature ? (and also for others properties like
ConsoleAppender.isFollow or FileAppender.immediateFlush, ...)
I also would love to be able to dynamically update thess properties. I
don't think it is currently possible.
Or at least I would like to be able to replace an Appender in the
Configuration (by a new one) without removing the Appender from all the
previously associated LoggerConfig.
Regards,
Clément

Yes, I'm programmatically adding appenders. I understand the point of view.
And what about having access to the properties of the appender as the
target of the ConsoleLogger? I know that this property is wrapped into an
OutputStream and into a OutputStreamManager but I think it could be nice to
have access to it from the ConsoleAppender.

Are you programmatically adding the Appender?
I suggest the reconfiguration method because it allows for gracefully
switching to a new configuration. Some appenders need fields to remain
immutable for performance or safety reasons, so creating a new Appender on
reconfigure is generally the safer option.

Yes, I know that.
So if I have 10 LoggerConfigs that use the same Appender and I want to
change a property of this Appender, I should create a new one and update
the appender list (remove the old one and add the new one) of my 10
LoggerConfigs?
There isn't a simpler way, is there?

If you reconfigure Log4j at runtime, you can switch over to a new
LoggerConfig without losing any messages. If you're holding direct
references to LoggerConfig, you should probably step back a level and get
that on demand instead.
