class Foundation_API Logger : public Channel
/// Logger is a special Channel that acts as the main
/// entry point into the logging framework.
///
/// An application uses instances of the Logger class to generate its log messages
/// and send them on their way to their final destination. Logger instances
/// are organized in a hierarchical, tree-like manner and are maintained by
/// the framework. Every Logger object has exactly one direct ancestor, with
/// the exception of the root logger. A newly created logger inherits its properties -
/// channel and level - from its direct ancestor. Every logger is connected
/// to a channel, to which it passes on its messages. Furthermore, every logger
/// has a log level, which is used for filtering messages based on their priority.
/// Only messages with a priority equal to or higher than the specified level
/// are passed on. For example, if the level of a logger is set to three (PRIO_ERROR),
/// only messages with priority PRIO_ERROR, PRIO_CRITICAL and PRIO_FATAL will
/// propagate. If the level is set to zero, the logger is effectively disabled.
///
/// The name of a logger determines the logger's place within the logger hierarchy.
/// The name of the root logger is always "", the empty string. For all other
/// loggers, the name is made up of one or more components, separated by a period.
/// For example, the loggers with the name HTTPServer.RequestHandler and HTTPServer.Listener
/// are descendants of the logger HTTPServer, which itself is a descendant of
/// the root logger. There is not limit as to how deep
/// the logger hierarchy can become. Once a logger has been created and it has
/// inherited the channel and level from its ancestor, it loses the connection
/// to it. So changes to the level or channel of a logger do not affect its
/// descendants. This greatly simplifies the implementation of the framework
/// and is no real restriction, because almost always levels and channels are
/// set up at application startup and never changed afterwards. Nevertheless,
/// there are methods to simultaneously change the level and channel of all
/// loggers in a certain hierarchy.
///
/// There are also convenience macros available that wrap the actual
/// logging statement into a check whether the Logger's log level
/// is sufficient to actually log the message. This allows to increase
/// the application performance if many complex log statements
/// are used. The macros also add the source file path and line
/// number into the log message so that it is available to formatters.
/// Variants of these macros that allow message formatting with Poco::format()
/// are also available. Up to four arguments are supported.
///
/// Examples:
///     poco_warning(logger, "This is a warning");
///     poco_information_f2(logger, "An informational message with args: %d, %d", 1, 2);
