Public Member Functions¶

PatternLayout ()
virtual ~PatternLayout ()
virtual std::string format (const LoggingEvent &event)
Formats the LoggingEvent in the style set by the setConversionPattern call. virtual void setConversionPattern (const std::string &conversionPattern)

Public Member Functions inherited from log4cpp::Layout
virtual ~Layout ()
Destructor for Layout.

Static Public Attributes¶

static const char * DEFAULT_CONVERSION_PATTERN = '%m%n'
The default conversion pattern. static const char * SIMPLE_CONVERSION_PATTERN = '%p - %m%n'
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'
A conversion pattern equivalent to the TTCCLayout.

log4cpp::PatternLayout::PatternLayout ()¶

log4cpp::PatternLayout::~PatternLayout () [virtual]¶

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) [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

Exceptions

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.
