class PatternComponent

Public Member Functions¶

PatternLayout ()
virtual ~PatternLayout ()
virtual std::string format (const LoggingEvent &event)
Formats the LoggingEvent in the style set by the set_conversion_pattern call. virtual int set_conversion_pattern (const std::string &conversionPattern)
Sets the format of log lines handled by this PatternLayout. virtual std::string get_conversion_pattern () const
virtual void clear_conversion_pattern ()

Static Public Attributes¶

static const char * BASIC_CONVERSION_PATTERN = '%R %p %c %m%n'
A conversion pattern equivalent to the BasicLayout.

log4tango::PatternLayout::PatternLayout ()¶

log4tango::PatternLayout::~PatternLayout () [virtual]¶

void log4tango::PatternLayout::clear_conversion_pattern () [virtual]¶

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

Formats the LoggingEvent in the style set by the set_conversion_pattern call. By default, set to '%%m%%n'

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.
• %m - the message
• %n - the platform specific line separator
• %p - the level
• %r - milliseconds since this layout was created.
• %R - seconds since Jan 1, 1970
• %u - clock ticks since process start
• %x - the NDC
