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
