void log4tango::PatternLayout::clear_conversion_pattern () [virtual]
std::string log4tango::PatternLayout::format (const LoggingEvent & event) [virtual]

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.
