"15:49:37,459".Deprecated.
Implement this interface for your own strategies for outputting log
statements.
Interface for attaching appenders to objects.
A straightforward implementation of the
AppenderAttachable
interface.AppenderFinalizer has a single method that will finalize
resources associated with a LogBrokerMonitor in the event
that the LF5Appender class is destroyed, and the class loader
is garbage collected.Abstract superclass of the other appenders in the package.
The AsyncAppender lets users log events asynchronously.
Render
org.xml.sax.Attributes objects.Use this class to quickly configure the package.
BoundedFIFO serves as the bounded first-in-first-out
buffer heavily used by the AsyncAppender.This class has been deprecated and
replaced by the
Logger subclass.Implemented by classes capable of configuring log4j using a URL.
ConsoleAppender appends log events to
System.out or
System.err using a layout specified by the user.Counts the number of bytes written.
CyclicBuffer is used by other appenders to hold
LoggingEvents for immediate or differed display.DailyRollingFileAppender extends
FileAppender so that the
underlying file is rolled over at a user chosen frequency.This abstract layout takes care of all the date related options and
formatting work.

Throwable.printStackTrace.
This filter drops all logging events.

This interface defines commonly encoutered error codes.
Appenders may delegate their error handling to
ErrorHandlers.This appender listens on a socket on the port specified by the
Port property for a "RollOver" message.
The
FallbackErrorHandler implements the ErrorHandler
interface such that a secondary appender may be specified.FileAppender appends log events to a file.
Check every now and then that a certain file has not changed.
Users should extend this class to implement customized logging
event filtering.

FormattingInfo instances contain the information obtained when parsing
formatting modifiers in conversion modifiers.
HardenedObjectInputStream restricts the set of classes that can be
deserialized to a set of explicitly whitelisted classes.

maintaining the logger hierarchy.
Listen to events occuring within a
Hierarchy.This layout outputs events in a HTML table.

JMSAppender.Extend this abstract class to create your own log layout format.
Defines the minimum set of levels recognized by the system, that is
OFF, FATAL, ERROR,
WARN, INFOinvalid input: '<'/code, DEBUG and
ALL.This is a very simple filter based on level matching.
This is a very simple filter based on level matching, which can be
used to reject messages with priorities outside a certain range.
LF5Appender logs events to a swing based logging
console.Load resources (or images) from various sources.
The internal representation of caller location information.
An
EntityResolver specifically designed to return
log4j.dtd which is embedded within the log4j jar
file.A
Log4JLogRecord encapsulates
the details of your log4j LoggingEvent in a format usable
by the LogBrokerMonitor.This is the central class in the log4j package.
Implement this interface to create new instances of Logger or
a sub-class of Logger.
A
LoggerRepository is used to create and retrieve
Loggers.The internal representation of logging events.
The LogLevel class defines a set of standard logging levels.
Thrown to indicate that the client has attempted to convert a string
to one the LogLevel types, but the string does not have the appropriate
format.
This class used to output log statements from within the log4j package.
Use the
LogManager class to retreive Logger
instances or to operate on the current LoggerRepository.This class provides parameterized logging services
using the pattern syntax of java.text.MessageFormat.
LogRecord.
An interface for classes which filters LogRecords.
This class provides parameterized logging services
using the SLF4J pattern syntax.
This is a base class for LogMF and LogSF parameterized logging classes.
The main application.
The MDC class is similar to the
NDC class except that it is
based on a map instead of a stack.Render
javax.jms.Message objects.The NDC class implements nested diagnostic contexts as
defined by Neil Harrison in the article "Patterns for Logging
Diagnostic Messages" part of the book "Pattern Languages of
Program Design 3" edited by Martin et al.
No-operation implementation of Logger used by NOPLoggerRepository.
No-operation implementation of LoggerRepository which is used when
LogManager.repositorySelector is erroneously nulled during class reloading.
Append to the NT event log system.
A NullAppender merely exists, it never outputs a message to any
device.
An always-empty Enumerator.
Implement this interface in order to render objects as strings.
The
OnlyOnceErrorHandler implements log4j's default
error handling policy which consists of emitting a message for the
first error in an appender and ignoring all following errors.A convenience class to convert property values to specific types.
A string based interface to configure package components.
An implementation of LogRecordFilter which always returns true.
PatternConverter is an abtract class that provides the
formatting functionality that derived classes need.
A flexible layout configurable with pattern string.
Most of the work of the
PatternLayout class
is delegated to the PatternParser class.Refrain from using this class directly, use
the
Level class instead.Allows the configuration of log4j from an external file.
Used for inferring configuration information for a log4j's component.
Prints the configuration of the log4j default hierarchy
(which needs to be auto-initialized) as a propoperties file
on a
PrintWriter.General purpose Object property setter.
Thrown when an error is encountered whilst attempting to set a property
using the
PropertySetter utility class.QuietWriter does not throw exceptions when things go
wrong.
Formats a
Date by printing the number of milliseconds
elapsed since construction of the format.Map class objects to an
ObjectRenderer.The
LogManager uses one (and only one)
RepositorySelector implementation to select the
LoggerRepository for a particular application context.A simple application to send roll over messages to a potentially
remote
ExternallyRolledFileAppender.RollingFileAppender extends FileAppender to backup the log files when
they reach a certain size.
Deprecated.
RootLogger sits at the top of the logger hierachy.
SimpleLayout consists of the level of the log statement,
followed by " - " and then the log message itself.
A simple
SocketNode based server.Send an e-mail when a specific logging event occurs, typically on
errors or fatal errors.
Sends
LoggingEvent objects to a remote a log server,
usually a SocketNode.Sends
LoggingEvent objects to a set of remote log servers,
usually a SocketNodes.Read
LoggingEvent objects sent from a remote client using
Sockets (TCP).A
SocketNode based server that uses a different hierarchy
for each client.Starts an instance of the LogFactor5 console for off-line viewing.
This is a very simple filter based on string matching.
Use SyslogAppender to send log messages to a remote syslog daemon.
SyslogQuietWriter extends QuietWriter by prepending the syslog
level code before each printed String.
SyslogWriter is a wrapper around the java.net.DatagramSocket class
so that it behaves like a java.io.Writer.
The TelnetAppender is a log4j appender that specializes in
writing to a read-only socket.
Render
ThreadGroup objects in a format similar to the
information output by the ThreadGroup.list() method.ThreadLocalMap extends InheritableThreadLocal
to bequeath a copy of the hashtable of the MDC of the parent
thread.ThrowableInformation is log4j's internal representation of
throwables.
Implemented by classes that render instances of
java.lang.Throwable (exceptions and errors)
into a string representation.
Implemented by logger repositories that support configurable
rendering of Throwables.
Utility class for transforming strings.
Implementions of this interface allow certain appenders to decide
when to perform an appender specific action.
TTCC layout format consists of time, thread, category and nested
diagnostic context information, hence the name.
