RollingFileAppender extends FileAppender to backup the log files when they reach a certain size.
The default constructor simply calls its parents constructor.
| RollingFileAppender | ( | const LayoutPtr & | layout, |
| const LogString & | fileName, | ||
| bool | append | ||
| ) |
Instantiate a RollingFileAppender and open the file designated by
filename.
The opened filename will become the ouput destination for this appender.
If the append parameter is true, the file will be appended to. Otherwise, the file desginated by filename will be truncated before being opened.
| RollingFileAppender | ( | const LayoutPtr & | layout, |
| const LogString & | fileName | ||
| ) |
Instantiate a FileAppender and open the file designated by
filename.
The opened filename will become the output destination for this appender.
The file will be appended to.

Reimplemented from RollingFileAppenderSkeleton.
| int getMaxBackupIndex | ( | ) | const |
Returns the value of the MaxBackupIndex option.
| long getMaximumFileSize | ( | ) | const |
Get the maximum size that the output file is allowed to reach before being rolled over to backup files.
| void setMaxBackupIndex | ( | int | maxBackupIndex | ) |
Set the maximum number of backup files to keep around.
The MaxBackupIndex option determines how many backup files are kept before the oldest is erased. This option takes a positive integer value. If set to zero, then there will be no backup files and the log file will be truncated when it reaches MaxFileSize.
| void setMaxFileSize | ( | const LogString & | value | ) |
Set the maximum size that the output file is allowed to reach before being rolled over to backup files.
In configuration files, the MaxFileSize option takes an long integer in the range 0 - 2^63. You can specify the value with the suffixes "KB", "MB" or "GB" so that the integer is interpreted being expressed respectively in kilobytes, megabytes or gigabytes. For example, the value "10KB" will be interpreted as 10240.
| void setMaximumFileSize | ( | int | value | ) |
Set option to value.
The handling of each option depends on the OptionHandler instance. Some options may become active immediately whereas other may be activated only when activateOptions is called.
Reimplemented from FileAppender.
