   void log4tango::PatternLayout::clear_conversion_pattern () [virtual]
   std::string log4tango::PatternLayout::format (const LoggingEvent & event) [virtual]
       Formats the LoggingEvent in the style set by the set_conversion_pattern call. By default,
       set to '%%m%%n'

       Reimplemented from log4tango::Layout.

   std::string log4tango::PatternLayout::get_conversion_pattern () const [virtual]
   int log4tango::PatternLayout::set_conversion_pattern (const std::string & conversionPattern)
       [virtual]
       Sets the format of log lines handled by this PatternLayout. By default, set to '%%m%%n'.
        Format characters are as follows:

       • %%%% - a single percent sign
       • %c - the logger
       • %d - the date
          Date format: The date format character may be followed by a date format specifier
         enclosed between braces. For example, %d{%H:%M:%S,%l} or %d{%d %m %Y %H:%M:%S,%l}. If no
         date format specifier is given then the following format is used: 'Wed Jan 02 02:03:55
         1980'. The date format specifier admits the same syntax as the ANSI C function strftime,
         with 1 addition. The addition is the specifier %l for milliseconds, padded with zeros to
         make 3 digits.
       • %m - the message
       • %n - the platform specific line separator
       • %p - the level
       • %r - milliseconds since this layout was created.
       • %R - seconds since Jan 1, 1970
       • %u - clock ticks since process start
       • %x - the NDC
       Parameters:
           conversionPattern the conversion pattern
       Exceptions:
           ConfigureFailure if the pattern is invalid
