## Detailed Description

This is the central class in the log4cplus package.

One of the distintive features of log4cplus are hierarchical loggers and their evaluation.

See the user manual for an introduction on this class.

## Constructor & Destructor Documentation

## ◆ LoggerImpl()

dcmtk::log4cplus::spi::LoggerImpl::LoggerImpl | ( | const log4cplus::tstring & | name,
|  | Hierarchy & | h )
| protected

This constructor created a new `Logger` instance and sets its name.

It is intended to be used by sub-classes only. You should not create loggers directly.

Parameters

  name | The name of the logger.
  h | Hierarchy

References name.

Referenced by setAdditivity().

## Member Function Documentation

## ◆ callAppenders()

virtual void dcmtk::log4cplus::spi::LoggerImpl::callAppenders | ( | const InternalLoggingEvent & | event | ) |
| virtual

Call the appenders in the hierrachy starting at `this`.

If no appenders could be found, emit a warning.

This method calls all the appenders inherited from the hierarchy circumventing any evaluation of whether to log or not to log the particular log request.

Parameters

  event | The event to log.

## ◆ getChainedLogLevel()

virtual LogLevel dcmtk::log4cplus::spi::LoggerImpl::getChainedLogLevel | ( |  | ) | const
| virtual

Starting from this logger, search the logger hierarchy for a "set" LogLevel and return it.

Otherwise, return the LogLevel of the root logger.

The Logger class is designed so that this method executes as quickly as possible.

Reimplemented in dcmtk::log4cplus::spi::RootLogger.

## ◆ getLogLevel()

LogLevel dcmtk::log4cplus::spi::LoggerImpl::getLogLevel | ( |  | ) | const
| inline

Returns the assigned LogLevel, if any, for this Logger.

Returns
  LogLevel - the assigned LogLevel.

References ll.

## ◆ isEnabledFor()

virtual bool dcmtk::log4cplus::spi::LoggerImpl::isEnabledFor | ( | LogLevel | ll | ) | const
| virtual

Check whether this logger is enabled for a given LogLevel passed as parameter.

Returns
  boolean True if this logger is enabled for `ll`.

References ll.

## Member Data Documentation

## ◆ additive

bool dcmtk::log4cplus::spi::LoggerImpl::additive
| protected

Additivity is set to true by default, that is children inherit the appenders of their ancestors by default.

If this variable is set to `false` then the appenders found in the ancestors of this logger are not used. However, the children of this logger will inherit its appenders, unless the children have their additivity flag set to `false` too. See the user manual for more details.

Referenced by setAdditivity().

## ◆ parent

SharedLoggerImplPtr dcmtk::log4cplus::spi::LoggerImpl::parent
| protected

The parent of this logger.

All loggers have at least one ancestor which is the root logger.
