Detailed Description

PatternLayout is a simple fixed format Layout implementation.

Constructor & Destructor Documentation

◆ PatternLayout()

virtual

Member Function Documentation

◆ clearConversionPattern()

void log4cpp::PatternLayout::clearConversionPattern ( )
virtual

◆ format()

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.

◆ getConversionPattern()

std::string log4cpp::PatternLayout::getConversionPattern ( ) const
virtual

◆ setConversionPattern()

void log4cpp::PatternLayout::setConversionPattern ( 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 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
conversionPatternthe conversion pattern
Exceptions

Member Data Documentation

◆ BASIC_CONVERSION_PATTERN

const char * log4cpp::PatternLayout::BASIC_CONVERSION_PATTERN = "%R %p %c %x: %m%n"
static

A conversion pattern equivalent to the BasicLayout.

◆ DEFAULT_CONVERSION_PATTERN

const char * log4cpp::PatternLayout::DEFAULT_CONVERSION_PATTERN = "%m%n"
static

The default conversion pattern.

◆ SIMPLE_CONVERSION_PATTERN

const char * log4cpp::PatternLayout::SIMPLE_CONVERSION_PATTERN = "%p - %m%n"
static

A conversion pattern equivalent to the SimpleLayout.

◆ TTCC_CONVERSION_PATTERN

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.
