Constructor & Destructor Documentation

RollingFileAppender (   )

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.

Member Function Documentation

void activateOptions (  log4cxx::helpers::Pool &  pool  )  [virtual]

Prepares RollingFileAppender for use. 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  )

virtual void setOption (  const LogString &  option, const LogString &  value )  [virtual]

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.
