Static Public Attributes
static const char * DEFAULT_CONVERSION_PATTERN = '%m%n'
The default conversion pattern.

A conversion pattern equivalent to the SimpleLayout.
static const char * BASIC_CONVERSION_PATTERN = '%R %p %c %x: %m%n'
A conversion pattern equivalent to the BasicLayout.
static const char * TTCC_CONVERSION_PATTERN = '%r [%t] %p %c %x - %m%n'

Member Function Documentation
void log4cpp::PatternLayout::clearConversionPattern () [virtual]
std::string log4cpp::PatternLayout::format (const LoggingEvent & event)
[virtual]
Formats the LoggingEvent in the style set by the setConversionPattern
call. By default, set to '%%m%%n'
Implements log4cpp::Layout.
std::string log4cpp::PatternLayout::getConversionPattern () const [virtual]
void log4cpp::PatternLayout::setConversionPattern (const std::string &
conversionPattern) throw (ConfigureFailure) [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 category %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 priority %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

const char * log4cpp::PatternLayout::BASIC_CONVERSION_PATTERN = '%R %p %c
%x: %m%n' [static]
A conversion pattern equivalent to the BasicLayout.
const char * log4cpp::PatternLayout::DEFAULT_CONVERSION_PATTERN = '%m%n'
[static]
The default conversion pattern.
const char * log4cpp::PatternLayout::SIMPLE_CONVERSION_PATTERN = '%p -
%m%n' [static]
A conversion pattern equivalent to the SimpleLayout.
const char * log4cpp::PatternLayout::TTCC_CONVERSION_PATTERN = '%r [%t] %p
%c %x - %m%n' [static]
A conversion pattern equivalent to the TTCCLayout. Note: TTCCLayout is
in log4j but not log4cpp.
