Both or either ;) I used an
interface RollCondition
{
boolean roll( LogEvent event, File file );
}
that allowed you to select the conditions under which you roll.

Abvsolutely. The other thing I started to implement was an interface like
interface RollStrategy
{
File nextFile( File oldFile );
}
Which would do the actuall rolling. So you could select the strategy with
which you name files - ie
my.log
my.log.1
my.log.2
my.log.3
(Files after 3rd generation are deleted)
vs
my.log
my.log.20010722
my.log.20010611
...
(logs are infinite and use dates to roll)
etc.
So you had configurable generation count (ie number of files that could be
present), format of filename etc.
Howeverything I did was raw and untested properly so it may be better to work
together to get once better tested system ;)
