CFileLogRoute

Package	system.logging
Inheritance	class CFileLogRoute » CLogRoute » CComponent
Since	1.0
Version	$Id$
Source Code	framework/logging/CFileLogRoute.php

CFileLogRoute records log messages in files.

The log files are stored under logPath and the file name is specified by logFile. If the size of the log file is greater than maxFileSize (in kilo-bytes), a rotation is performed, which renames the current log file by suffixing the file name with '.1'. All existing log files are moved backwards one place, i.e., '.2' to '.3', '.1' to '.2'. The property maxLogFiles specifies how many files to be kept.
