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.
