Subject Re: Trigger RollingRandomAccessFile appender programmtically?
Date Mon, 21 Dec 2015 21:22:01 GMT
I can easily write an "OnDemandTriggeringPolicy" class that implements TriggeringPolicy.
I just don't see how I can get the RollingRandomAccessFile to use it.
I'd prefer to just put it in my log4j.xml as one of the <Policies>, but I don't see
how to configure log4j to allow that.

on whatever your criteria is.  As an alternative you can locate the Appender in the configuration,
obtain its manager and kick off the rollover in your code.
