LoggerFactory	The LoggerFactory is a utility class producing Loggers for various logging APIs, most notably for log4j, logback and JDK 1.4 logging.
LoggerFactoryBinder	An internal interface which helps the static LoggerFactory class bind with the appropriate ILoggerFactory instance.
LoggerRepository	A LoggerRepository is used to create and retrieve Loggers.
LoggingEvent
LoggingEvent
LogLog	This class used to output log statements from within the log4j package.
LogManager	This class is a minimal implementation of the original org.apache.log4j.LogManager class (as found in log4j 1.2) delegating all calls to SLF4J.
Marker	Markers are named objects used to enrich log statements.
MarkerFactory	MarkerFactory is a utility class producing Marker instances as appropriate for the logging system currently in use.
MarkerFactoryBinder	An internal interface which helps the static MarkerFactory class bind with the appropriate IMarkerFactory instance.
MarkerIgnoringBase	This class serves as base for adapters or native implementations of logging systems lacking Marker support.
MDC
MDC	This class hides and serves as a substitute for the underlying logging system's MDC implementation.
MDC.MDCCloseable	An adapter to remove the key when done.
MDCAdapter	This interface abstracts the service offered by various MDC implementations.
MDCFriend
MessageFormatter	Formats messages according to very simple substitution rules.
NamedLoggerBase	Serves as base class for named logger implementation.
NDC	A log4j's NDC implemented in terms of SLF4J MDC primitives.
NoOpLog	Trivial implementation of Log that throws away all messages.
NOPLogger	A direct NOP (no operation) implementation of Logger.
NOPLoggerFactory	NOPLoggerFactory is an trivial implementation of ILoggerFactory which always returns the unique instance of NOPLogger.
NOPMDCAdapter	This adapter is an empty implementation of the MDCAdapter interface.
NullEnumeration	An always-empty Enumerator.
OptionHandler
OutputChoice	This class encapsulates the user's choice of output target.
OutputChoice.OutputChoiceType
PatternLayout	This class is a minimal implementation of the original Log4J class.
Priority	Refrain from using this class directly, use the Level class instead.

RollingFileAppender	This class is a minimal implementation of the original Log4J class.
SimpleLayout
SimpleLog	Simple implementation of Log that sends all enabled log messages, for all defined loggers, to System.err.
SimpleLogger	Simple implementation of Logger that sends all enabled log messages, for all defined loggers, to the console (System.err).
SimpleLoggerConfiguration	This class holds configuration values for SimpleLogger.
SimpleLoggerFactory	An implementation of ILoggerFactory which always returns SimpleLogger instances.
SLF4JBridgeHandler	Bridge/route all JUL log records to the SLF4J API.
