AbstractFileAppender.Builder<B extends AbstractFileAppender.Builder<B>>	Builds FileAppender instances.
AbstractManager	Abstract base class used to register managers.
AbstractOutputStreamAppender<M extends OutputStreamManager>	Appends log events as bytes to a byte output stream.
AbstractOutputStreamAppender.Builder<B extends AbstractOutputStreamAppender.Builder<B>>	Subclasses can extend this abstract Builder.
AbstractWriterAppender<M extends WriterManager>	Appends log events as strings to a writer.
AppenderSet	A deferred plugin for appenders.
AppenderSet.Builder
AsyncAppender	Appends to one or more Appenders asynchronously.
AsyncAppender.Builder
ConfigurationFactoryData	Factory Data that carries a configuration.
ConsoleAppender	Appends log events to System.out or System.err using a layout specified by the user.
ConsoleAppender.Builder<B extends ConsoleAppender.Builder<B>>	Builds ConsoleAppender instances.
CountingNoOpAppender	No-Operation Appender that counts events.
DefaultErrorHandler
FailoverAppender	The FailoverAppender will capture exceptions in an Appender and then route the event to a different appender.
FailoversPlugin	The array of failover Appenders.
FileAppender	File Appender.
FileAppender.Builder<B extends FileAppender.Builder<B>>	Builds FileAppender instances.
FileManager	Manages actual File I/O for File Appenders.
HttpAppender	Sends log events over HTTP.

HttpManager
HttpURLConnectionManager
MemoryMappedFileAppender	Memory Mapped File Appender.
MemoryMappedFileAppender.Builder<B extends MemoryMappedFileAppender.Builder<B>>	Builds RandomAccessFileAppender instances.
MemoryMappedFileManager	Extends OutputStreamManager but instead of using a buffered output stream, this class maps a region of a file into memory and writes to this memory region.
NullAppender	An Appender that ignores log events.
OutputStreamAppender	Appends log events to a given output stream using a layout.
OutputStreamAppender.Builder	Builds OutputStreamAppender instances.
OutputStreamManager	Manages an OutputStream so that it can be shared by multiple Appenders and will allow appenders to reconfigure without requiring a new stream.
RandomAccessFileAppender	File Appender.
RandomAccessFileAppender.Builder<B extends RandomAccessFileAppender.Builder<B>>	Builds RandomAccessFileAppender instances.
RandomAccessFileManager	Extends OutputStreamManager but instead of using a buffered output stream, this class uses a ByteBuffer and a RandomAccessFile to do the I/O.
RollingFileAppender	An appender that writes to files and can roll over at intervals.
RollingFileAppender.Builder<B extends RollingFileAppender.Builder<B>>	Builds FileAppender instances.
RollingRandomAccessFileAppender	An appender that writes to random access files and can roll over at intervals.
RollingRandomAccessFileAppender.Builder<B extends RollingRandomAccessFileAppender.Builder<B>>
ScriptAppenderSelector
ScriptAppenderSelector.Builder	Builds an appender.
SmtpAppender	Send an e-mail when a specific logging event occurs, typically on errors or fatal errors.
