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.
