Class RotatingLogfile

java.lang.Object

to.etc.util.StandardLogfile

to.etc.util.RotatingLogfile

All Implemented Interfaces:

ILogSink

public class RotatingLogfile
extends StandardLogfile

Encapsulates a rotating logfile. It contains methods to write log records to a file; the file will rotate to a new name every day round midnight. By default it will clear out files older than 7 days when rotating. Before using the logfile you MUST have called setName, or you must have used the constructor which passed a name. The name is the full path to a logfile including a filename. The system will insert a date part BEFORE the filename extension for every logfile generated. So when entering a name like /var/log/serverinfo/mailer.log a generated name could be something like /var/log/serverinfo/mailer2001-12-31.log
