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)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

Member Data Documentation

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.
